Hi.
So i have a few DECO mesh networks up and running about the place.
I have recently begun adding some cctv cameras at these locations and have run into some interesting and rather frustrating issues.
 

1. on one network where i have a mesh of 6 deco units across 2 small houses where i am trying to get 12 cameras to record on an 16ch NVR I am experiencing devices jsut dropping off the network completely. As long as I keep the number of cameras linked to the 16ch NVR less than 6 everything is normal.
The moment i add no.6 other devices disappear and then come back randomly. Completely cannot see them on the app network list nor can you ping them.
FYI all cctv equipment set with static IPs below the DHCP issuing range.
I have set all devices to NOT be mesh enabled. Only mesh devices are my laptop and my phone but still 6 cameras and down goes usually the same culprits but nothing to do with IP conflicts, nor signal strength. the most notorious has got a good 54% signal strength and is only 5m open air away from the closest mesh point.
wired cameras are not effected only wifi cameras. I have tried dropping resolution changing frame rates nothing seems to make it better.
Note cameras are all HIK vision devices even the switches and the NVR

2.on another network i have all devices issued IPs from DHCP reservations these behave similar but not entirely the same. Again 6 cameras seems to be a magic number but the devices do not ghost themselves rather just become difficult to reach even though they are in good network coverage and can be reached over the internet via their native platforms. This network i have a mix of devices some porting through iscee platform other through ezviz and others through hikvision onto a smaller 8ch NVR

Is there a streaming limitation on the deco units?
What could be causing the sudden network instability when 6 cameras are trying to be recorded at an NVR?
