Wattage output capacity of the RLN8-410

I recently purchased the RLN8-410 NVR and installed 3 422 cameras, and one 423 camera. The 422 cameras all require 6.5 Watts of power to function, the 423, which has PTZ, requires 22 Watts. I needed an injector for the 423. So my question is this: What's the maximum Wattage output of the RLN8-410? How many more 422 cameras can I set up and not need another injector?

Because, if I were to use all the ports available for just 422 cameras, that's a total of 52 Watts (8 x 6.5). Yet, the NVR would not support 3 422's and 1 423 camera ((3 x 6.5)+22), which is a total of only 41.5 Watts.

Well? What's the answer? I don't see that Reolink replied. I can't find the maximum wattage on the NVR, or on the specs page. So....what is it?

Hi, sorry for our late reply. The maximum Wattage output of the RLN8-410 single port is 25W. And the total output of the RLN8-410(with one HDD) is about 57W. Please kindly note.
