Hi, I am Ziyad, Project In-Charge for a company called GIS in UAE. We are facing a problem with the DVRs that we installed in one of our projects. we have got 7 DVRs with 10/13 cameras connected to each. 2 PTZs per DVR till DVR-4. Also, we have connected Intrusion Detection/Alarm System to these DVRs so that the PTZ will jump to the pre-assigned presets according to the Alarms. The problem is that the DVRs hang frequently. Then we need to restart the DVRs for it to function again. Please reply if you have any idea about it or ask me for more details/conditions at site. BR, Ziyad

Hi All, This is to inform you that DM has replaced all 7 DVRs to newer model and now everything is working fine. Thanks for all your comments. Ziyad

yes, DM is about to replace the DVRs.....

Exactly... this is on more than on 1 DVR.... So I am scratching my head!!!!!! WE are going to replace the DVRs with another model because the client is important... lets check.. meanwhile wait for all your replies and solutions....

Soundy, Here below i mention the model info, Brand: Dedicated Micros (UK) Model: DVIP- EXPRESS, 16 channel, 2 TB storage.

Hi Rory, We have tried the same, disonnected the alarm inputs at this time the DVR works smoothly but some of them still hangs at some time. No we dont have a voltage regulators but here no need of that. we usually dont use that. Some DVRs still records some not... We also doubt the Hardware!!!..

hi Tom, sorry for the late reply. They are new installs but running for last 3 months in the same manner. the Manufacturer tried upgrading them many times but still same..

Hi Matt, The DVRs are Standalone. Most of them have same symptoms. No, they are in clean and Air Conditioned Control room. They are just locking up, no error displays.. nothing. When DVR is working fine and all Alarms connected, it gets hanged after a while or a day. Hanging means, it doesn't hang the whole system. it still shows the monitor with real time view (people/car moving), but we will not have any control over it. like we will not be able to control with the Keyboard, cannot playback, no TCP/IP connection, date and time freezed... All these happens till we restart the DVR. then it will work normal for sometime/day. Again Hangs!!!!
