![]() ![]() You will be able to connect more than 2 cameras that way. If you want to be absolutely safe then you will need to get one of the expensive 802.3bt switches from Ubiquiti (like USW-48-POE) which cost a ton of money. In my testing both cameras were pulling about 16.5W during the night. In real life scenario I haven't seen G3 PRO going above 9W when infrared is activated (about 4.5W when infrared is off). So in sum that makes 25W which is well above the 20W threshold. G3 PRO and G4 PRO max power draw is the same - 12.5W. ![]() ![]() My rackmount switch provides 802.3at which is about 30W, but UniFi Switch Flex using 802.3at has a power budget of only 20W. It seemed like a good moment to swap out the G3 (non-pro) camera as well since it's underperforming in dark environment compared to G3 PRO model. Fortunately a friend of mine had UniFi Switch Flex test unit which accepts active 802.3af/at/bt PoE as power input. The voltage drops from 24v to about 22.5v which is enough for G3 (non-pro) model to go into a reboot loop.Īt this point I figured that I have two options - either use multiple single port passive Ubiquiti PoE 24v-24W injectors for each NanoSwitch or go with an active PoE and ditch all the passive PoE injectors and NanoSwitch. However in my testing I found out that there is a voltage sag whenever you try to push more than 15W through the panel. The total max usage in this scenario should not exceed 23W so the 30W output should be sufficient. Not mutch (1.5W), but still it needs to be accounted for when you are pushing to the limits. Also you should not forget that NanoSwitch is also consuming power. Camera specs say that G3 PRO max consumption is 12.5W and G3 is 9W (with optional IR extender). reading the PoE injector specs closely I found that it is compatible with 802.3af and 802.3at standarts which *should* give me about 30W output. Unfortunately the situation didn't unfold like I wanted to. Since I have multiple cameras and multiple NanoSwitches, it was quite a mess in my wall-mount rack cabinet using multiple PoE injectors so I decided to go with a PoE injector panel: PoE injector 12 port Gigabit But when you have multiple devices which are quite demanding on the power, the situation gets quite tricky. Now, if you have only one end device then it's straight forward to just connect either active or passive PoE depending on the device. Unfortunately UniFi NanoSwitch does not accept 802.3af/at active PoE and I had to use passive PoE injector (of course the same brand - Ubiquiti POE-24-24W). My current setup in one particular location involves two cameras - G3 and G3 PRO connected to UniFi NanoSwitch which is connected to TP-Link T1600G-28PS PoE switch. Next few paragraphs will tell you how to set everything up and how not to mess things up. Today I got my hands on G4 PRO and I decided to do a direct comparison on a real life scenario by testing the camera where I have G3 PRO installed right now.įirst of all I must tell you that a setup of more than one camera on one ethernet cable can be a pain in the ass if not done correctly. I have been using UniFi products for some time now, mainly G3 and G3 PRO. ![]()
