The poe power supply technology allows one cable to transmit both signals and power the camera. This saves the cost of wiring and facilitates construction. Below Hikvision as an agent Beijing Hua An Ruicheng Xiao Bian for everyone to introduce Hikvision poe network camera how to distinguish.
Which network cameras support poe power supply? Can the model be differentiated?
Have you ever studied the model of Hikvision network camera? In fact, it still does not support PoE. The Hikvision network camera model has an annotation.
For example: DS-2CD3120FD-I, this DS-2CD3120FD-I, does not support PoE power supply.
Corresponding, the same appearance of the DS-2CD3120F-I is to support PoE power supply.
Let's compare: DS-2CD3120FD-I, DS-2CD3120F-I
Is it already found?
You guessed it right, for the camera, if the second "-" in the name before, with "D" is the symbol of PoE.
PoE is not supported if the model has "D"; PoE is supported if there is no "D"!
Second, which Hikvision cameras support PoE
For example DS-2DE4572-AE, for the dome camera, whether to support PoE power supply is not reflected in the second "-" before, the power information of the dome is reflected in the end of the model.
For example: DS-2DE4572-AE
The end of the "AE" is the power supply information, A represents the AC, E on behalf of supporting PoE power supply!
Example: DS-2DC2103-DE3/W, DS-2DC2103-DE3/W
When we look at this model again, we know that this dome is a "D"-DC and "E", it also supports PoE!
Third, PoE power supply introduction, at or af?
1.PoE powers the cables in two pairs of network cables.
At present, there are two types of PoE: one is 802.3af (PoE) and the other is 802.3at (PoE+).
Among them, 802.3at (PoE+) can provide more power, so some of Haikang's ball machines support PoE+.
2. The device is detected before PoE power is supplied. If the device does not support this function, or if the device has been powered on independently and does not require PoE power, the power device will not supply PoE to the device.
Therefore, the PoE-powered camera can be connected to an external power supply. When the camera is plugged into a PoE-powered switch or video recorder, the power-supplying device will not supply power to the camera. Don't worry about being burned.
This is why we use a multimeter to measure less than the voltage supplied by PoE.
Fourth, those devices can provide power
Such as the above, Hikvision video recorder model is DS-7108N-SN/P, where "/P" refers to a network port with multiple PoE power supply, which can supply power to front-end equipment that supports PoE.

Fourth, those devices can provide power
PoE-enabled switches and PoE-enabled hard disk recorders provide power.
Such as the above, Hikvision video recorder model is DS-7108N-SN/P, where "/P" refers to a network port with multiple PoE power supply, which can supply power to front-end equipment that supports PoE.
