Difference between monitoring camera dc and poe

The differences between poe cameras and ordinary cameras are as follows:

1, POE camera can supply power to the camera through network cable. Power supply only needs a network cable, which can transmit data and current at the same time, and the power supply signal is available. This kind of POE can save cable and plug-in, and the camera deployment points are diversified, which is not limited by power supply. The advantages of centralized power supply can also be realized. At the same time, it has the functions of energy saving, safety and lightning protection.

2. Ordinary cameras Each camera has an independent power supply. Non-POE power supply is generally recommended for long distance, and POE can be considered for short distance.

Camera or webcam is a kind of video input equipment, which belongs to a kind of closed-circuit television and is widely used in video conferencing, telemedicine, real-time monitoring and other fields. Cameras generally have the basic functions of video shooting, transmission and still image capture. After the image is captured by the lens, the image is processed by the photosensitive element circuit and control element in the camera and converted into a digital signal that can be recognized by the computer. Then it is input into the computer through the parallel port and USB connection, and then the image is restored by software, thus forming a picture.
