NVR 16 port included power adapter enough to run 16 cameras + 2 HDD?

I have the 16 port NVR from Reolink and need information on what to do if I use all 16 ports for the following cameras:

4x RLC-423

3x RLC-420

9x RLC-410

2x internal SATA hard drive.

I currently have 3x RLC-420, 9x RLC-410 and 2x hard drives connected and my power draw at the wall is at 100watts. The supplied AC adapter is rated for 48V x 2.5amps = 120watts. Taking into account 90% efficiency of the AC adapter that means I am currently using 90 watts out of the available 120 watts. Adding just 2x RLC-423 would put me over the edge.

What are my options if I want to add more power hungry cameras?

Well, you can use power adapter (DC12V) to power the added rlc-423 in case the total power all your cameras comsume exceeds 120watts.

Hi Alireza

Refer to：

Base on your calculation, your available watts has only 30 watts left, but one RLC-423 use 22W. so as you said, there is not enough watts for the RLC-423s.

howdymoody was right.
You can use PoE switch to connects RLC-423 and NVR and make sure to use a power adapter on PoE switch that provides watts required for RLC-423s.

phraew - I prefer to connect all my devices directly to the NVR without using an additional injector or separate PoE switch. One possible solution is to buy a AC to 48v DC inverter that goes up to 200watts and install the same power tip the NVR uses. This should work right?

Also, is that table correct?
802.3af = 15.40 watts max

802.3at = 25.50 watts max

I think the table has it backwards if I am not mistaken.

Hi Alireza

Thank you for the reminder. I've correct it.

We recommend to use the adapter in the box we provided. By this way, you may connects only one RLC-423 to the NVR directly without separate adapter. For more RLC-423s, we suggest you to use additional PoE injector/switch (802.3AT) or adapter.
The method you mentioned has the possibility burn up the NVR board.
