What is the difference between a wireless surveillance camera and a cable surveillance camera?
CCD is a charge-coupled device (Charge Coupled Device) short, it can turn the light into charge and the charge storage and transfer, can also be stored in the charge out of the voltage changes, it is ideal camera components, with its composition CCD camera has a small size, light weight, free from magnetic field, with anti-vibration and impact characteristics are widely used.
Monitoring camera is a semiconductor imaging device, which has a high sensitivity, anti-glare, small distortion, small size, long life, anti-vibration and so on. Surveillance camera security system, the image generation is mainly from the CCD camera
Wired relative to the wireless signal a little better, the wireless a little easier, the quality of a clear choice of cable is better.
Surveillance camera prices are generally more than 100 to have a million, tens of thousands of precision will be much higher, and very sensitive, such as those according to the license plate, their accuracy is high, can automatically focus. I used to buy home before the home network camera, also asked some of the company's offer, and finally buy the wood Jitong, the effect is very good, the site forgotten! You can Baidu look
