Monitoring requires encoders, decoders, storage, display devices, and so on.If you need to connect to the TV can extract the files, then buy a small hard disk recorder machine, plus a special small camera.

Q:What should be paid attention to in the installation of security monitoring?

The correct grounding can minimize the effects of the ground loop. The voltage difference between the different ground shall not exceed 100mVAC (measuring the pressure difference between the disconnected coaxial cable and the shield layer and the ground terminal of the BNC behind the device).

Q:What are the common types of CCTV cameras?

Q:How to choose the transmitter in security monitoring system?

Video bandwidth is an old growth issue. The video bandwidth is not enough, the detail of the monitor screen is not clear enough, the horizontal resolution is low, and even the color distortion or video loss is serious. Because of the importance of video bandwidth for image quality, some unscrupulous vendors intentionally exaggerate the video bandwidth of the product to deceive customers. For example, a digital video optical transceiver manufacturers claim their video bandwidth is 8M, but the release of video sampling frequency is 12.5M. According to Nyquist's law of sampling, the signal should be sampled at least two times as much as the signal frequency. So now, the transmitter manufacturers the theory of video bandwidth in any case can not be more than 6.25M. Obviously, this is a lie to exaggerate the quality of cheating customers, so that no business reputation vendors should not consider the scope of the purchase. But not all customers can accurately identify vendors lie, for general contractors and users, by observing the details of the image, you can rough judgment of the device's video bandwidth.
