Do IP PTZ's need extra power

[bm_99]

Evening all, new member on here so hopefully can get some good info and give some out

Just wanted to find out for IP systems mainly HIK, do the PTZ (mainly DE range) need extra power, like 24 ac or even Hi-POE or is the 16 channel NVR enough to give out power?

Thanks

The camera can be powered entirely through PoE+ fine, but you need to make sure your NVR's available power budget is adequate to power the camera. What NVR specifically will you be using? It all depends on how many cameras are already being powered by the NVR etc. See Dan's post in this PoE vs PoE+ thread below:

Be aware of the power budget of the NVR, the 7616-K2 model has a 200W budget and so you have to be aware if you have all or almost all the PoE ports being used that you have enough budget left to support the 2 PTZs, standard PoE cameras usually uses a max. of 15.4W but more often they use around 8-12W and the 4225IW PTZ camera you want uses a max. of 18W

You can check the PoE power usage of your cameras if you have a directly connected monitor as there is a menu you that shows you the live power usage of the cameras connected, but unfortunately this menu is not available via browser access. To be safe and to make sure you don't exceed that power budget of the NVR we usually recommend connecting PTZs remotely to a switch and power with a separate PoE+ injector - Trendnet TPE-115GI Gigabit Power over Ethernet Plus Injector

NVR on site is the DS-7616NI-K2/16p

Cameras wise it probably will total 14 with 2 or 3 PTZ's (the DS-2DE4225-IW-DE Models)

You should be fine. Your NVR ports support PoE+ and has a 200W power budget.

Standard cameras will use an absolute max of 10W, and those PTZs a max of 18W, so should be well under the budget all in.

The below is from the NVRs datasheet, IEEE 802.3 af/at is just the techy term for PoE+.
