Why we need the "surveillance camera"?
Surveillance camera can protect your family's child and old person's safety or it can record who go into your home and doing some thing when you go out. (Some camera have record function, otherwise need record card )
Our surveillance camera you can put inside clock, radio, or other covert environment. Human's eye is very difficult to detect.
What're the difference between a wired camera and a wireless camera?
A wired camera needs a cable connect the camera to a TV or monitor. The image signal is passed through the camera, through the cable, and arrive your TV or monitor, then allows you to watch the video (audio). All wired cameras must use cable to connect the camera.
A wireless camera does not need cable connects the camera to the TV or monitor. The image signal is transmitted through the air to the TV or monitor directly, or to a receiver.
.
How to the wireless camera work?
Like telephone, there have two kinds of telephone, wired telephone and wireless one. Only different is processes that how deal with transmit information with method. Therefore, the wireless camera is also same, they are depend on "the electromagnetic wave"come to arrive that the wireless audio and video.

What are different between CCD and CMOS ?
Both CCD or CMOS image sensors are electronic devices that use a variety of technologies to transform an image into an electric image. In the process of reading the value in the image, CCD sensors supply high-quality, low-noise images. but CCDs consume lots of electric power. CMOSs operate on lower voltage and therefore consume much less power. So CMOS have much longer battery life than CCDs.
Other difference between these two sensors is that the manufacturing costs of CCD much more expensive than CMOS.
Based on these differences,. There is a higher image quality but higher power consumption (CCD) compared with lower image quality but longer power consumption (CMOS).

What is PAL. NTSC and Secam?
PAL , NTSC, and Secam is mode of receive the signal.
NTSC (National Television Standards Committee) is a standard used in North America and Japan . PAL a standard used almost everywhere else in the world, SECAM is used separated around the world and can be found in France, parts of Greece, Eastern Europe, Russia, Africa and a few other parts of the world.
If your TV/VCR/camcorder support multi-systems, you can use either PAL or NTSC camera
NTSC and PAL standard are not interchangeable. For example, you can't display video input from a PAL camera on a NTSC
What is the camera resolution and Lux mean?
Resolution is a measurement unit of the camera's clarity. The resolution is high, the camera image is better clearer. "Lux" can affect account of light .If you want see clear under the low light, the more lower the "Lux" ,the more better one.
pybase.com is a Torrance, CA based business with the expertise and inventory to meet all surveillance and spying needs. Combining the virtues of a brick-and-mortar storefront with a fully functional retail website in English, Spanish, Portuguese, and French, Spybase.com offers the best of both worlds.
The names of the game in surveillance and spying are discrete, secret, and hidden. The successful application of many of the devices offered by Spybase requires particular standards and custom application if they are to go unnoticed. The easiest way to verify if a particular product lives up to expectations is to come in and see it in person. Many people don?t buy clothes and shoes over the internet, despite easy-to-understand standardized sizes, because of sometimes a good fit just isn?t that simple. What goes for a pair of sneakers more than applies to a hidden camera.
A good example of this is the Stealth Telephone to PC Recorder (http://www.spybase.com/stealth-telephone-recorder-p-567.html). With an easy-to-use installation procedure, this device can be up and running in 5 minutes, and will allow for easy telephone conversation recording that will be stored directly in a desktop or laptop PC. However, just because one wants to record their telephone conversations does not mean they want everyone to know they are doing it. Setting up a desk to discretely tuck away the device itself, as well as the telephone cables, is the sort of thing that might be different for every desk an can really only be judged once the buyer has seen the device itself. These considerations doubly apply if the Stealth Telephone to PC Recorder is to be used in recording the conversations of people using your phone, but without their knowledge. In that instance, a good fit in hiding the device and the suspicious cables is a must.
Also available is the Mini Watchcamera Spybase Style (007watchdvrspy/mg - http://www.spybase.com/mini-watchcamera-spy-base-style-p-644.html). This is a very James Bond piece of technology that offers color video recording capacity complete with audio. The memory of the watch allows for 2 hours of video at 352x288 resolution (the equivalent of 2 gigabytes), comes with a USB port, and the watch is warrantied for two years. However, the previously mentioned issues with clothing arise when it comes to this watch. It is a great piece of technology, but does it look like the sort of thing you would wear? You can see a picture on the website, but there is more to it than that. How big is it? Furthermore, is it easy to make surreptitious use of the watchcamera? It doesn?t do much good to have a secret watchcamera if it looks like you are filming people with your watch. These are questions best answered by going down to the store and looking at the watch in person.
These are the advantages of a brick-and-mortar store. The advantages of the a brick-and-mortar store with a substantial retail website are that you can go to the store in person, shop, check out your options, and postpone making a decision for a later date. With the information in hand, you can go home, mull the matter over, perhaps double check the places you wish to secrete your spy gadgets, and then make the purchase online. Just because it is to your advantage to go to the store in person to look at the merchandise does not mean you need to go back to purchase it!
