Why Separate PoE from Hikvision Surveillance Equipment?385

PoE (Power over Ethernet) is a technology that allows network devices to receive power over the same Ethernet cable that carries data. This can be a convenient and cost-effective solution for powering surveillance cameras, as it eliminates the need for separate power cables and outlets. However, there are some potential drawbacks to using PoE with Hikvision surveillance equipment.

PoE Can Overload Hikvision NVRs

One of the biggest concerns with using PoE with Hikvision surveillance equipment is that it can overload the NVR (network video recorder). This can occur if the PoE switch is not powerful enough to handle the load of all the connected cameras. When this happens, the NVR can shut down or crash, resulting in lost footage.

PoE Can Cause Interference with Hikvision Cameras

Another potential problem with using PoE with Hikvision surveillance equipment is that it can cause interference with the cameras. This can occur if the PoE switch is not properly shielded or if the Ethernet cables are not properly installed. Interference can cause the cameras to lose connection or to produce poor-quality images.

PoE Can Be a Security Risk

Using PoE with Hikvision surveillance equipment can also pose a security risk. This is because PoE switches can be hacked, which can allow unauthorized users to access the surveillance footage. In addition, PoE switches can be used to launch denial-of-service attacks, which can prevent authorized users from accessing the surveillance footage.

Alternatives to PoE

If you are concerned about the potential drawbacks of using PoE with Hikvision surveillance equipment, there are several alternatives available. One option is to use a separate power supply for each camera. This is more expensive than using PoE, but it is more reliable and secure.

Another option is to use a PoE switch that is specifically designed for Hikvision surveillance equipment. These switches are typically more expensive than standard PoE switches, but they are less likely to cause problems with Hikvision cameras.

Conclusion

PoE can be a convenient and cost-effective solution for powering surveillance cameras. However, there are some potential drawbacks to using PoE with Hikvision surveillance equipment. If you are concerned about these drawbacks, there are several alternatives available.
