Can I only record a 4k camera at 5fps on my ProConnect NVR?

The 16 channel ProConnect NVR’s stated frame rate specification on 4k cameras of 5 fps (10fps on the 8 channnel ProConnect NVR) when recording on all channels simultaneously. Network video recorders are rated and limited by their total recording bandwidth, not a per channel maximum. 

The ProConnect NVR can record at the maximum frame rate of any connected camera, including 4k at the expense of other connected cameras framerates. This is a limitation of all Network Video Recorders and not specific to AvertX.
