Examples for possible errors reported by error relay:
■
Recording underrun (images are overwritten too early)
■
Recording overrun (insufficient allocated storage)
■
Storage warning threshold reached
■ Hard disk error (not locked, removed, or faulty)
■
Hardware error (e.g. faulty DSP, video decoder, or clock module)
■
Video signal failure (faulty camera or video cable), low contrast image (e.g.
caused by lens cover)
■
Remote connection (triggered by alarm or routine call) cannot be
established
For a detailed list of error messages that can trigger the error relay, refer to
chapter "Log file". Viewing the Log File automatically causes reset of the
error message; the error relay is de-ernergised and Error LED goes out. Refer
to the manual of the respective SmartControl software for more information
on log file configuration and evaluation.
Sabotage protection The error relay is pulled in idle - no error. Therefore the error relay can be used
as sabotage detector, as it automatically falls off in the event of power failure
(e.g. caused by cut power lines). Depending on the error relay wiring, an
interruption of the relay line itself can be reported as well.
There is a theoretical possibility that sabotage protection will not work if
error relay switching is not consistent with the operating mode.
