The difference between PoE monitoring and ordinary monitoring: PoE monitoring only requires one network cable to power the camera, which can transmit data and current at the same time; ordinary monitoring requires a separate power supply. Since the power supply power of PoE monitoring cannot be too large, ordinary monitoring can be used for long distances, and PoE monitoring can be used for short distances.

The difference analysis is as follows:

POE camera

POE-enabled network cameras can power the camera through a network cable. Only one network cable is needed for power supply, which can transmit data and current at the same time, and the power supply signal is available.

This POE can eliminate the need to lay out cables and strips, and has a variety of camera deployment points, without being limited by power supply. Moreover, the advantages of centralized power supply can be realized. At the same time, it has energy saving, safety, lightning protection, etc.

The disadvantage is that the power supply cannot be too large. For example, cameras with more LED lights or infrared lights cannot be used. Most dome cameras cannot be used because they are too powerful. The requirements for POE switches are relatively high. Once the switch power supply is damaged, , all cameras cannot work, and it is recommended not to be too far away, otherwise the power supply may be insufficient.

Ordinary camera

Non-POE power supply means that each camera has a separate power supply.

It is generally recommended to use non-POE power supply for long distances, and POE can be considered for short distances.
