It used to be that cameras were VGA resolution and that was easier to handle on wireless connections. The RLC-411WS has a resolution of 2560x1440 and a bit rate of about 6144K bps. That’s a lot of data and excellent for reading those auto license plates at distance if you need to zoom a frame. The downside is that on a wireless connection, you will drop frames due to environmental conditions. Consider wiring those cameras. I have three Reolink cameras on my NVR which is a QNAP NAS.
