davey 0 Posted July 21, 2008 Hi im responsible for the overall working cond of our CCTV system, just ensuring it works and nothing else. The problem we have is when pressing the EVENT key on the keyboard you only get camera 1 events. The set up is a digi sprite 2 and 2 colour vcl domes, when you power the system down and re boot for the first five mins or so the camera's will auto swop when a alarm is received, but after mins no event is captured on the camera 2 and both camera's stop swopping over when a alarm is picked up. I have had a cctv company trying to help with the problem, but we are all scratching our heads. DM has suggested it could be the hard drive corrupted or the memory module on the board, can anyone suggest any ideas. Regards davey Share this post Link to post Share on other sites

alanjh1965 0 Posted July 23, 2008 When you reboot do you just pull the plug or power down using the 1 or 4 key? I say this because this can cause the Telematary parameters to reset back to default (NONE) How are the alarms recieved at the DM is it motion or do you have detectors wired into the DM ? DM Tech support are usually good at diagnosing problems so you might have to send it back Share this post Link to post Share on other sites
davey 0 Posted July 24, 2008 Thanks for the reply, using gjd passive's which when activated go to the dome camera and from dome to the dm unit, the domes move to the correct pre sets and we definently have a signal going to the DM unit. Power the unit down using correct procedure through menu and no 1 camera key for five seconds then pull the supply plug. Re loaded the software today just in case, but still not cured.

galaxy60 0 Posted August 9, 2008 With the alarms on the DM units either it be the internal or external alarm module you can not go over 1 ohms resistance and the GJD detectors have an inbuilt 36 ohm resistor across the relay contacts causing the DM to not see any activity. I would recommend you have each alarm input to drive a relay and then use the clean pair of contacts to activate the alarm inputs of the DM unit. Share this post Link to post Share on other sites
