I've the same problem with the DS-2CD2322WD-I and the DS-2CD2342WD-I.
Both camera's with the latest firmware...
Hikvision can't resolve the problem.
They think it's an hardware problem in the light sensor.
Fidal,
It depends on the ask from the customer.
Mostly i install Hikvision or Panasonic.
When i have an office building with access control etc. I use UTC, just for the great imployment with the ATS860 software!
