Start-up
Observe all safety and operating instructions before operating the device for the first time.
Warning
When installing the device in an existing video surveillance system, ensure that all devices
have been disconnected from the mains power circuit and low-voltage circuit.
Warning
Improper or unprofessional work on the mains network or domestic installations puts both
you and others at risk.
Connect the installations so that the mains power circuit and low-voltage circuit always run
separately from each other. They should not be connected at any point or become
connected as a result of a malfunction.
Care and maintenance
Maintenance is necessary if the device has been damaged (e.g. damage to the power cable and plug,
or the housing), or if liquids or foreign bodies have got into the interior of the device, or if it has been
exposed to rain or damp, or if it does not work properly or has been dropped.
Maintenance
If smoke, unusual noises or smells develop, switch the device off immediately and unplug from
the socket. In such cases, the device should not be used until it has been inspected by a
qualified technician.
Have all maintenance tasks carried out by qualified technicians only.
Never open the housing on the device or accessories unless this is necessary. As there is
always a risk to life due to electric shock when the housing is open, only open the housing when
the device is disconnected from the power source.
With some devices, opening the device is unavoidable and permitted for the following purposes:
Installing the device
Inserting a storage medium (SD card or hard disk drive)
Accessing essential functions (reset button or WPS button)
Cleaning
Only clean the device housing with a damp cloth.
Do not use solvents, white spirit, thinners etc. or any of the following substances:
Brine, insect spray, solvents containing chlorine or acids (ammonium chloride), or scouring
powder.
Rub the surface gently with the cotton cloth until it is completely dry.
The device operates with a dangerous voltage level. When conducting maintenance
or cleaning work, disconnect the device from the mains.
