Baby Monitor Tips

1. Some baby monitor is too sensitive that all the voice around can be hear from the receiver, then you can't judge which is the you baby, some times you can turn down the voice to solve this problem.

2. The interference signal. if baby monitor's frequence is the similar to other device, they will interfere each other, you can hear the radio from it.



3. Generally speaking, we need a baby monitor in the night, so you must by a night vision baby monitor.

4. If you have a plan to add a camera to you baby monitor system in the future, you can buy a multi-channel monitor like some 4 CH video baby monitor, this type product can receive 4 video signals from 4 cameras.

5. Baby monitor have many style: common style baby monitor, flower baby monitor, toy baby monitor, or multi-camera baby monitor with professional look. Thinking which you baby will like and won't scream to grab it in his hands.

6. Baby monitor screen: baby monitor screen is the critical factor decided the price, 1.5 inch baby monitor mark a price between $80 -$90, 1.8 inch baby monitor more or less $95-$100, and the 2.5 inch baby monitor nearly need $140, all monitors here refers to the wireless video baby monitor.

7. Distance: Many baby monitor told us it can use in 100m, be careful, the 100m lenght here is in direct line condition and without block. Most of the baby monitors effective distance is shorter than this by far.

8. Baby monitor can use three type power source，DV in, AA battery or Lithium battery. The type use li-ion battery is better.

How Captured a Clear Image in The Environment with Very Poor Light Conditions

Surveillance cameras demand captured clear picture in very poor light conditions at night, or no light environments. In the camera's indicators, we often can see the item: low illumination level .

1, the concept of illumination level

Illuminance is a unit to measure the sensitivity of the camera, represent by unit:Lux, that is to say, How dark lighting conditions the camera can capture the image. Indicating the lower the value, a lower light conditions the camera can take images. We know that the camera generated video signal by a nominal value of 1v, the standard value is 700mv, such as using the lens with aperture of F1.2, when the scene's illuminance values being photographed is 0.02Lux, the camera outputs a video signal amplitude is 33%-50% of the standard value of 700mv, when the lowest illumination lever for this camera is 0.02Lux/F1.2. Test the value of the illumination level should be noted that the size of the lens aperture, the smaller the F value, the bigger the aperture, the lower illumination need. The illumination values are different for different aperture.

2, The program to achieve low-light videography

We know that CCD camera can be divided into color and black/white cameras, the lowest illumination of ordinary cameras is in the table below.


The lowest illumination level of common cameras

The wave length range of visible light is 380nm ~ 780nm, wavelength of visible light is divided into red, orange, yellow, green, cyan, blue, purple from long to short, wavelength shorter than purple's wavelengths is known as UV, longer than red light is called infrared light. there is a layer of transparent electrode can absorb UV in the surface of CCD sensor, the CCD can not accept UV. Common color CCD camera chip have red, green and blue color filters, so color camera can not feel the infrared light . While the ordinary black/white CCD camera spectral range is very wide, not only can feel the visible light, but can feel the infrared light.

Based on the above principle, in the environment light conditions are very poor , engineers have often taken the following programs to get the clear images.

(1) general low illumination black and white CCD camera + IR Light

Install infrared light radiation "light" in monitoring site, generate infrared light ordinary camera can capture while the human eye can not see, can achieve night shooting through the black and white CCD camera.

(2) color to black and white camera + IR Light

The color to black and white video cameras means it is a color camera in the day, in the poor lighting conditions at night time, the use of the characteristics black and white images have a high sensitivity to the infrared , automatically switch to black and white mode, shooting in conjunction with infrared. Low-light cameras must be met to the lowest illumination the infrared light support.

(3) IR Illumination Color Camera

Infrared sensitivity of infrared low-light color camera is 4 times higher than the average the common camera, you can work at zero illumination (0Lux).

(4) low-speed shutter camera

Low-speed shutter camera also known as the cumulative picture camera, via store continuous multi-frame (up to 128 ) blurred picture due to insufficient light in computer memory, to build up a clear picture, with the help of SLOWSHUTTER technology to achieve shooting under 0.008LUX/F1 .2 illumination. This low-light video camera apply to museum, night observation of biological activity at night, the military coastline monitoring prohibit red, UV damaged.

(5) ultra-low-light cameras

Ultra-low-light camera use EXVIEWHAD technology to enhanced sensitivity greatly, its color illumination is up to 0.05LUX, black and white is up to 0.003-0.001LUX. When equipped special infrared devices, can get high-resolution black and white images, to achieve 0Lux shooting.

PTZ(Pan/Tilt/Zoom) For Monitoring

In fact, PTZ is a installation platform composed of two AC motors, can move horizontal and vertical direction. However, please note that the PTZ we talk about is different from the PTZ in camera equipment. Camera PTZ equipment is general just a tripod, can only adjust the position through the hands; while monitoring system PTZ can control the rotation and movement direction through the remote control system.

There Are Various Types of PTZ
* PTZ is divided into indoor and outdoor type by the environment used in, the main difference is the outdoor-type have good sealing performance, waterproof, dustproof and heavy load.
* By installation is divided into side-loading and lifting, that is to say, where PTZ is installed, on the ceiling or mounted on the wall.
* According to shape is divided into common type and ball type, ball PTZ is placed PTZ in a hemispherical, spherical shield, besides prevent the dust from interfering the image, it is hidden, beautiful and fast.
* According to motor function PTZ can be divided in to the level PTZ and all-round PTZ.
* In accordance with working voltage is divided into fixed-speed AC and DC high-speed variable-speed PTZ.
* In accordance with load capacity is divided into light-load PTZ, moderateduty PTZ and heavy-load PTZ.
* In accordance with the load installation is divided into top-mounted and side mounted PTZ.
* According to use environment is divided into general-purpose and special-type. Universal one refers to the use in non-flammable, non-corrosive gas or no dust atmospheric environment, can be divided into the use type and outdoor-type. The most typical application for special type PTZ in explosion-proof PTZ.

In the selection of PTZ we must consider installation environment, installation, operating voltage, load size, also have to consider cost performance and the aesthetic appearance and other factors.

The Internal Structure of PTZ
There are two motors within the all-round PTZ, respectively control the up-down direction and left-right direction rotation. The different voltage also determines the overall work voltage of the PTZ, generally the AC 24V, AC 220V and DC 24V. when receive the up-down action voltage, vertical motor rotate, the rotate transmission through the gear box drive wheel rotation; When receive the left and right horizontal move voltage, the horizontal motor rotation drive the horizontal gear at the bottom of the PTZ through gear box.

Be noted that PTZ has a horizontal and vertical spacing restrict bolt, PTZ achieve spacing restriction function by two micro-switches respectively. When the rotation angle achieve a pre-set limit bolt, micro-switch moves to cut off power supply, PTZ stop turning. Limit device can be located outside of PTZ, adjustment process is simply, and can also be located in PTZ inside, adjust through peripheral adjustments, the adjustment process is complexity relatively. But the tightness of the external limit device is not better then the PTZ's limit PTZ devices built-in.

Indoor PTZ and Outdoor PTZ broadly is similar with each other generally, but because the weight of a larger outdoor protective cover, so that the load of capacity the PTZ must increase. Meanwhile, hot and cold changes is obviously in outdoor environment, vulnerable to erosion by rain or moisture. Outdoor PTZ therefore are generally designed as seal water-resistant type. Outdoor PTZ also features a high torque and choke protection circuits to prevent burned by PTZ motor force starting in the freeze. Under the harsh conditions at low temperature can also install the temperature control PTZ-type heater.

Definition and TVLine

Definition refers to the clarity of the detailed pattern and its borders video images.

Definition, generally from the the point of view of VCR, compare the image quality by the clarity of the image replayed, so the term commonly used the world definition. While The camcorder generally used resolution to measure it ability: "decompose the details of scene photographed". Unit is the "TV lines (TVLine, TVL)" also known as line. Means that , equivalent to erect each line of scan lines the horizontal direction from the point of view, and then multiplied by 4 / 3 (Aspect Ratio), Constitute the total number of lines in horizontal direction, saying the horizontal decomposition force. It changes with the number of CCD Pixels, and the video bandwidth, the more pixels and the wider bandwidth is, the higher the decomposition ability is. The 625-line of PAL system is the the nominal vertical decomposition ability, except the the 50 lines in reverse process, the actual effective vertical decomposition ability is 575 lines. The level of decomposition ability up to 575x4/3 = 766 lines. But one of the major factors restricting the lines number is bandwidth. Empirical data shows that use 80 lines / MHz to calculated to reproduce the TV lines (line number) is available. Such as can use 6MHz bandwidth to transmit image quality have 480 line decomposition ability. Low-end home use video recorder, such as VHS, can have up to 240 lines of resolution. Digital camera record data in digital signal format, resolution up to 500 lines or more. (Normal TV resolution is about 280 TVLines, VCD's resolution is 230 TVLines).

How the IR Camera Work

Infrared camera has an addtional active infrared emission devices, receiving systems have a similar principles as natural light camera.



Natural light camera is reflect imaging after received natural light.

So in a dark environment, there is no natural light, we'll turn on the lights to let the camera get light.

Active infrared emission opened the equivalent of a infrared light, illuminated the shooting area, and then accept the reflective infrared to imaging.

While the human eye can not see infrared light, but the infrared camera can get the message.

Multi-point Touch Screen

Multi-point Touch Screen Description:
Different from the traditional single-point touch screen, the most prominent feature of multi-point touch screen is that it can use multiple fingers of two hands even multiplayer control the contents in screen simultaneously, more convenient and user-friendly. Multi-point touch technology also known as multi-touch technology. Multi-touch is divided into two levels in practical applications: one is the master chip can capture multi-point signal simultaneously; the other is able to judge the significance of each way finger touch signal. In other words, is the ability to provide users with gesture recognition. In the products already listed on Apple's iPhone and the MacBook notebook can basically achieve the purpose of this application, but the iPhone is currently only allows two fingers to complete the rotation , zooming and other functions simultaneously, is at best a a double touch, the Microsoft's Surface Computer is even more amazing, and that it can simultaneously generate multiple contacts to reflect. Compared with the small amount of signal lines of 4pin or 5pin in traditional single-point touch screen, the multi-point touch screen, carved out a lot of touch units on the conductive layer, each unit connect to external circuitry through a separate wire. Since all of the touch cell distributed in matrix-shaped row so regardless part of where the user finger access to, the system can react against the corresponding finger movement.



Multi-touch Can Be Divided Into Two Kinds:
Multitouch gestures and Multitouch all point, As our applications in Multitouch gestures, like the rotation, zoom and so on in pictures browse. Multitouch all point such as a game control, gps starting point and end-point control.

The difference between Multi-touch and Normal touch?
Common touch, usually only achieve single-point operation, for the button control, multi-touch can achieve the basic gestures operations, such as parallel move, zoom, rotate, and then by identifying the absolute position of multiple touch points to achieve user-defined gestures operation, more user-friendly operation. There are many factors to consider in design of multi-point touch screen, has a relationship to the number of touch sensor, touch screen controller chip selection, as well as the size of the touch screen, and with the calculation capacitive in touch screen design, touch sensor shape, size, structure, arrangement, the thickness of various materials, the spacing between LCD screen and touch screen, as well as the layout of the. He and finger touch CF related, such as touch-screen surface, the thickness of the thicker protective layer, then the thicker the protective layer is, the worse you touch sensing, also related with the operating position, depending on the touch screen controller chip performance.

Begin Treasure Hunt with Metal Detector

People will associate it with mine detectors when talking about metal detectors, engineers use it to detect buried mines. Metal detector is an instrument designed to detect metal, except for the detection of the mine have a metal or metal parts, it can also be used to detect the wires concealed in the walls, pipes and cables buried in underground, even underground treasure-hunting and found metal objects buried in the ground, of course, more metal detectors are now used in industrial purposes, such as food metallic contamination detection - Food metal detector, machine factory security metal detector - metal detector door, security door, Textiles metal impurities Broken Needle Detection - Needle detector and so on. Metal detectors can also serve as the equipment for youth national defense education and science activities, of course, after all is a fun entertainment device.



Theory of Metal Detector
Metal detectors use electromagnetic induction principle, using a coil with alternating current through, to produce a rapidly changing magnetic field. The magnetic field can be induced eddy currents in the metal object. Eddy currents will produce magnetic field, the magnetic field upside down affect the original magnetic field, triggering an audible warning signal in detector.



Underground Metal Detector
Is the application of advanced technology production, it have features like wide degree of detection, positioning accuracy, strong discernibility, ease operation and so on. Metal detector is mainly used to detect and identify hidden metal objects buried underground. besides used in military applications, is also widely used for: security checks, archeology, mineral prospecting, looking for scrap metal. Againreferred to as "Iron Exploration" is a good helper of waste recycling.



Hand-held Metal Detector
Hand-held metal detectors are designed to detect metal objects carried by people or objects. It can detect weapons, explosives or small metal objects in parcels, baggage, letters, fabric, etc carried by person. Its special appearance of the sensitive surface to make the operation simple and easy. Better than the ring-type hand-detection sensors. Ultra-high sensitivity, use for specific applications, such as prisons, chip plants, archaeological research, hospitals.

Video Doorbell, Let Me See Who Is Knocking The Door

The other name of the video doorbell is "video door phone"

In nowadays, the visual bell as a convenient and practical product, ranging from the late nineties to now, mainly used in commercial , the scale development is rapid, of universal applicate in high-rise residential buildings now in the urban district. when use, household heard the ring, receive the call visitors through the door host downstairs and engage in dialogue like video phone calls, while the host camera to receive video images in the visual extension through the downstairs, households observe the image display on the monitor extension to confirm the identity of visitors and finally decide whether to press the unlock button on indoor extension connect the host electric door locks to open the door, to allow visiting guests to enter.

Visual doorbell, using in one or more buildings in a residential building, when a number of households shared a door host, usually known as video intercom systems, building visual intercom systems; and used in single households, such as villas, often known as single-family video door phone or villa video doorbell.

Video doorbell already widely used in urban housing around the world current, its manufacturers concentrated in cities with relatively well-developed industry in security precautions, Guangzhou in Guangdong Province, Shenzhen of China, and Xiamen in Fujian Province and other cities in China.

Mobile Phone Signal Jammer

Mobile Phone Signal Jammer primarily for various groups of place like examination room, schools, gas stations, churches, courts, libraries, Conference Center (Room), theaters, hospitals, government, finance, prisons, police, military areas and other places prohibit the use of mobile phones.

It is understood that cell phone signal jammers on the market can limit cell phone signal which 500M meters away from the launch pad, and the radius larger then 20-meter. Shielding radius adjustable, it just block mobile phone signals, without an impact on other electronic devices. Save energy, power 20W - 480w.

When Mobile phone work, mobile phones and base stations connected via radio waves in a certain frequency range, complete the data transfer of data and voice via a certain baud rate and modulation manner. Contrapose this communication principle, cell phone signal jammers scan from the lower end of the channel frequency to the high-end in a certain speed in the course of their work. The scanning speed can form a garbled signal interference in the mobile phone when receive messages, the phone can not detect normal data sent from the base station, so that phone can not establish connection with the base station. Mobile perform a phemomenon like search network, no signal, no service system and so on.

The cell phone signal jammers in common market, its role frequency: 869 ~ 894MHz; 825 ~ 960MHz; 1805 ~ 1880MHz and 1900 ~ 1990MHz and so on. Role in Band of CDMA800, GSM900, DCS1800, PCS1900.

WIFI Advantages

WIFI is a wireless networking technology, we connected to a computer via network cable previously, but now it is through radio waves to connect internet; common situation is a wireless router, then in the effective range of radio coverage of the wireless router the WIFI connection can be used to interconnect, if the wireless router connected to an ADSL line, or other device access to the Internet, the wireless router is also known as "hot spots."
The common speed of wireless router now mostly 54M in the market, and then the higher level is the speed of 108M, of course, this speed is not the Internet speed, Internet speed depends mainly on the WIFI hot point internet line.

WIFI outstanding advantages
First, the radio waves have a wide range coverage, radio coverage based on Bluetooth technology is very small, only about 50 feet radius, about 15 meters, while the Wi-Fi is up to 300 feet radius, about 100 meters around, Needless to say the office, it can also be used in the whole building. A new switch launched by the Vivato recently, it is learned that this products can extend the current WIFI communication distance which close to 300 feet to 4 miles (about 6.5 km).

Second, although the wireless communication transmission quality under Wi-Fi technology, is not very good, data security performance worse than the Bluetooth，transmission quality also needs to be improved, but the transfer speed is very fast and can reach 54mbps, in line with personal and social information needs.

Third, the threshold firms entering the field is relatively low. Manufacturers only need to set up "hot spots" in the airport, railway stations, coffee shops, libraries and other densely populated place, and connect internet by high-speed access lines. In this way, because "Hot point" radio waves emitted from the access point can reach a radius of few tens of meters to 100 meters, the user in the region with notebook computer or WIFI mobile phone support the wireless LAN can high-speed access internet. In other words, Manufacturers do not have to spend money to carry on the network cabling, thus saving a lot of costs

No wiring
The main advantage of WiFi is does not require wiring, can be exempted from wiring constraints, so it is very suitable for the needs of mobile users, and has broad market prospects. Currently, it has been open up to to more other special sectors industries from the traditional health care, inventory control and management services, and even begun to enter the family, as well as educational institutions and other fields.

Health and Safety
IEEE802.11 required transmit power can not exceed 100 mW, the actual transmission power is about 60 ~ 70 mW, what this mean? Phone transmission power is about 200 milliwatts to 1 watt, the hand-held walkie-talkie up to 5 watts, and wireless networks is not direct contact with the human body like mobile phone, is absolutely safe.

Mobile Phone Operation System

Mobile phone operating system is generally only used in high-end smart phone. At present, in the smart phone market, the major part is personal information management-type mobile phone, as more manufacturers join the competition in the overall market has begun showing a decentralization trend. View from the market capacity, competition, status and application status point, the whole market is still in start-up phase.



Is currently used in mobile phone operating system, mainly refers six: PalmOS, Symbian, Windows CE, Linux, and Android, iPhoneOS.


Palm OS operating system

Palm OS operating system, self-developed by Palm Inc. and licensed to Handspring, Sony and Qualcomm, and other equipment manufacturers, the operating system is more inclined to PDA operating system.

Palm OS share dominance in the PDA market . Palm's product line itself including smart phones, then announced the merger with first smart phone developers Handspring, while establish the independent software sector.

Symbian system

Symbian is a real-time, multi-tasking pure 32-bit operating systems, with low power consumption, small memory occupation and other characteristics, very suitable for mobile phones and other mobile devices, through continuous improvement can support GPRS, Bluetooth, SyncML, and the 3G technology . The most important thing is that it is a standardized open platform, anyone can develop software for devices support Symbian . The difference with Microsoft products is, Symbian separate the mobile device common technology, which is the operating system kernel, with the graphical user interface technology , can be good adapt to platforms with different ways of input, can also enable manufacturers to produce more user-friendly operating interface for their products, in line with the trend of personalization, which is the the main reason user can see different look symbian system. Now the java process for this platform has begun to flourish on the Internet. Users can install the software, extended phone functions.

In the Symbian development stage, there have been three branches: namely, Crystal, Pearl, and Quarz. The first two principal directed towards the communications devices markets, also appear in the largest number of mobile phones, is the main force in the future smart phone operating system. The first mobile phone based on Symabian system in 2000, an Ericsson mobile phone models. But the real mature one and draw attention to the listing in 2001 at the same time is the Nokia 9210, which uses a Crystal branch system. Nokia 7650 and 3650 launched in 2002 is the Symbian Pearl sub-system models, in which 7650 is the first smart phone based on the 2.5G network products, they all belong to the 6.0 version Symbian. Sony Ericsson introduced a model also used the Pearl branch of Symbian, the version has been developed to 7.0, is designed for 3G network development, can be said to represent today's most powerful mobile operating system. In addition, Symbian support external storage devices started from version 6.0, such as MMC, CF card, making it full play the powerful expand capability, so that store more software and a variety of large-capacity multimedia files is possible.

Windows CE System

Windows CE system, including Pocket PC and Smartphone, the former focuses on the wireless PDA, the latter designed for mobile phones, a number of new mobile phone from the IT industry vendors to use, growth rates is fast.

Pocket PC 2002 launch of the Phone Edition (Phone Edition) application on the phone, the Chinese OEM machine Dopod 686 used this system. But it functions in mobile communications is not very comprehensive. In view of this situation, the end of 2002 Microsoft released an operating system SmartPhone2002 developed specifically for mobile phones , like the symbian Pearl, is a system designed for mobile communication devices .

From the reaction of a number of handphone manufacturers, only Samsung bought Microsoft's software licenses in the global top five handset makers, so its share of the cell phone market is still very low.

Linux Mobile Phone System

Linux system parts is an open source operating system, there are already many versions in vogue. But has not yet received wider support.

What is IPTV?

IPTV or Interactive network TV, is a new technologies which using broadband cable television network, set the Internet, multimedia, communications and other technologies in one, provide a variety interactive services including digital television for home users.



At home, users can enjoy the IPTV services in two ways: (1) Computer, (2) Network + ordinary TV set-top boxes). It can well adapt to the trend of rapid development of today's networks, make full and effective use of network resources. IPTV is different from the traditional analog cable TV, but also different from the classic digital TV. Because the traditional and classic digital TV has a frequency-division system, timing, one-way radio and other features; While digital TV has many technological innovations as opposed to the classic analog TV, but only the change of signal, but does not touch on media content mode of transmission.

IPTV is the use of a computer or set-top box + TV programming to complete receive video on demand, video broadcasting and Internet surfing functions. It uses highly efficient video compression technology that enables video streaming bandwidth 800Kb / s can be close to DVD television ratings (typically DVD video streaming bandwidth requirements is 3Mb / s), is a strong advantage to carry out the future class of video business, such as live video on the Internet, Long-range true video on demand, program source in terms of production, etc., is a new technical concepts.

The problems of traditional television is the one-way broadcast, it greatly limits the interaction between the audience and television service provider, and limits the individuation and real-time of the program. If an audience is not interested for all the channels content being broadcast, he (she) will have no choice. This is not only a loss of time for the viewers but also a waste of resources for cable TV service providers. In addition, the current implementation of the specific content of programs broadcast in a specific period of time for many viewers is inconvenient. The audience on night work might want to sometime in the early morning watching the news, but one ready to take a particular train passengers want to watch a soccer match scheduled for the evening broadcast video before leave home. Now appears to be impossible.

Use the IPTV will solve this problem, in addition, We have some cell phones built in the IPTV module, it is IPTV phone.

Mobile Phone Frequencies

Mobile phone tri-band generally refers to 900MHZ, 1800MHZ, 1900Mhz.

1900MHz is the U.S. GSM band.

900MHZ band is the frequencies of G mobile network, 1800MHz is the D-band network.
Therefore, 3-band phone will switch between 900 and 1800 frequency bands.
Which band specific choose will depend on network parameters at that time.
British bands are now using WCDMA and GSM, China's GSM is imported from Europe. Phone frequency divided into dual, tri-band, quad-band.

How To Sell in Bing Cashback

How Does it Work?

The cashback program is on a CPA basis (Cost Per Action). This means as an advertiser you only pay when a user takes an action in this case that means buys a product from you. Meanwhile to be listed you have "bid" on where you will be listed. The higher the bid the higher the CashBack that shows for the customer and the higher you show for that product in the results. Remember you do not have to pay for views or even clicks only when the customers buys the product. Cashback takes your bid and pays the customer a percentage of it and a percentage is kept by Microsoft. We of course don't know what percantage kept and what is passed to the customer.

Can Anyone Join?

Unfortunately not anyone can joing the CashBack program. There is a list of requirements to join Cashback as an Advertiser! In order to advertise in Live search using the Cashback service you have to meet several qualifications. First you must be headquartered in the United States.

Second you must have a retail site with e-commerce capabilities and be able to "fulfil" the physical shipment of the product. Basically you have to have an online store and be able to ship the product you are advertising. My guess is if your reading this an your not an affiliate you probably already have both.

Third you must be able to create and maintain a product data feed. CashBack needs this to be able to list your products with other competing products when users use Live Search. Depending on the e-commerce software package you are using most likely already have this. If you sell over 50 items I'd be pretty sure that you have it, if not get it not just for CashBack but for your sanity.

Fourth you have to be able to implement a standard tracking pixel on your website's order confirmation page. You should already have some type of tracking if you have an e-commerce site. If your not sure never fear most of the pre-built e-commerce software packages have this capability.

I'm Qualified How do I Join?

Currently most of the major vendors are already on the Cashback program like Borders, Tigerdirect, Ebay, etc. If you want to joind the service and you qualify you just have to fill out an Interest Form.

Or if you already advertise with MSN contact your representative and they will walk you through the rest of Microsoft Live Search Cashback signup.

Once your signed up you still need to bid on key words. Unlike Google Adwords you aren't bidding per click for each keyword which can take a lot of maintenance. Instead you're bidding per action in this case per purchase. Yes, you will be bidding against the "big companies" like Borders, Ebay, Tiger Direct, etc. Like Google adwords the key is to find good overlooked keywords and then get near the top of the search results by bidding higher. The higher you bid the more money that customers will get cashback.
