I am a Loss Prevention Detective, though I am not at liberty to disclose where I work.
We are currently having playback problems with our Time Lapse VCR. Our CCTV system is out dated, but we have managed to work successfully with it for several years.
We recently added a multiplexer (MV99p Multivision PRO) and a Time Lapse VCR (Sensormatic RV2400) to set-up to reduce the number of VCRs and tapes we use. The system is used and was procurred from another store. We have seven stationary B&W cameras hooked into the multiplexer and the Time Lapse VCR is recording device for it. Because of the Time Lapse VCR, whenever we need to review any footage of from this set-up, we must use the Time Lapse VCR for playback.
Now, the problem: When we review our VCR footage, the Time Lapse VCR is not giving us playback. Upon inspection, it was revealed that the system is recording, and we can view playback on the settings L06, L12, and L24. (We record on the setting L24 to get 24 hour footage from each T-120 tape... or 34 hours from a T-160.) However, through the use of the Multiplexer, we can view all 7 at once, or an individual camera, and when we view an individual camera the playback is further restricted to L12 and L24.
This system was installed by me in early June and we have not had any problems. This current issue began Friday, August 17th to our knowledge. We have not yet checked through older tapes to see if it was a problem before then but we are checking it. Incidently, Friday we had a power surge cause our whole CCTV system to blink out for a brief instant. Two more surges occured on Saturday, the following day.
We have checked and all of the system's plugs and cords are securely installed, but we have not performed a master reset yet. We do plan to do this, after having read a few other help requests on this and other sites, but if that does not help, can anyone here help?
