@chopstix, Thanks for the priceless advice (well almost - $399), will try to do without, system was working reasonably well for sometime and suddenly stopped - it must be reason for that.

My Reolink Application (Version 4.52.0.13) installed on iPhone (13 Pro) started to “play-up”: failing to connect, not responding when trying to do setting adjustment (IN or OUT – with Recording and Email notification).
NVR used is RLN – 410 (Hw No N7MB01, Fw v3.3.0.282_23103128), system works well when NVR is connected directly to monitor, also Application installed on laptop (Windows 11) works fine.
iPhone Application where I do settings “is dead”, deleting application and reinstalling did not help either.
Any good advice from experts?

@joseph_1979 Thanks Joseph

Haw to add on a new camera to existing system, what steps to follow? (NVR is RLN8-410, Camera RLC-510A)

@md Thanks

@joseph_1979
Thanks for reply. What FW stand for beside of "f*ckwit"? Did you mean sotware running equipment? If yes I checked settings NVR it's got the latest, about cameras I am confused; do I need to check and download it separately? If yes how doI do this?
Regards

About 30% movement in my RLN8-410 is not detected, not recorded, no alarm notification sent which makes me not so happy customer.
What could be the reason for that - deficiency of Reolink software?

@joseph_1979 Tanks for reply, I am not familiar with the system, I did not notice any errors display notification, and by the way on wich part of menu I should be looking to find them?

@joseph_1979 Sorry, perhaps I was not clear enough. Initially I connected 4 cameras and all were working correctly, after a few days one of them failed and I tried to reinstate it without success and after a couple days it started to work again that' the story

@joseph_1979 System I use is: REOLINK 8CH 4MP/5MP Home Security Camera System, 4pcs Wired 5MP Outdoor PoE IP Cameras with Audio Recording, IR Night Vision, IP66 Waterproof, 4K 8CH NVR with 2TB HDD (bought as a set with 4 original cameras). Not sure what do you mean by "restore" - how? Is reset (by dedicated camera push button) not good enough?
Regards
