Specification

The QS4M, Q4M and Q8M are the digital devices enabling the simultaneous displaying of 4 or 8 cameras on one monitor in high resolution. The Q4M and Q8M enable the camera switching according to the pre-programmed sequence and alarm processing.

Monitor Outputs

The QS4M, Q4M and Q8M have one main (MAIN) and one spot (QUAD) video output. The main video output is used for connecting a monitor and enables the displaying of split screen or cameras in full size. The spot video input is used only for the displaying of split screen and is usually used for recording to a VCR.

Alarm Processing

The Q4M and Q8M have one alarm input for each videoinput. The alarm output (relay) is switched ON during the alarm detection. The alarm output is signalled acoustically. The corresponding camera is displayed during the alarm. The alarm is put out of operation after finishing the set up time interval or after pressing any button.

Switching Sequence

The Q4M and Q8M enable the manual or automatic switching of particular cameras and split pictures on the main monitor output. The switching sequence can be set with the help of menu (TIME) in 1 - 99 sec.
