so why oh why don’t Reolink understand this! It’s a level of technical design incompetence that is staggering, I’ve just had this with my 8 week old 823A failing twice, I will address it but what is the Reolink position on this ?

I have the same problem with the same camera, direct power not Poe.
ive had the camera 8 weeks connected to Synology NAS, all works well until a couple of weeks ago when it was disconnected and was hunting and beeped about every 30 secs.
nothing worked, rebooted camera, router and NAS but after a couple hours it reconnected having changed nothing!

all worked well again until this morning - all the same symptoms - disconnected

took a video of its activity:
0-25 secs random Hunting around then stops 
26 secs beeps and stays still until 
42 secs starts random hunting again 
59 secs stops 
60 secs beeps again and continues the cycle

Yup, got it in UK, only seems to envelope vehicles though, not people?

@joseph_1979 thank you, had the same annoying problem - 5 hours of messing about and followed your suggestion - it works , cheers
