    Specifying a UPS

    Well, I am not going directly to the UPS vendor. Rather, I will be getting my CTV contractor to supply me the UPS.

    Specifying a UPS

    So, are you suggesting I have 33 UPS's in my CCTV control room?!? Wouldn't economies of scale come into play here i.e. get a larger one at less that 33 times a small one?

    Converting from analog to digital recording

    Yes, I am still inclined towards PC-based DVRs. Wow, plasma?? It is gonna cost right? I know it will look impressive on the wall and even help clear up the cramped space in the CCTV room but the cost of plasma screens might just wipe the budget!

    Specifying a UPS

    Our blackouts or brownouts are not very regular here. At most once in every 3 or 4 months. But we do have occasional LT/HT servicing which would require a shutdown of about 1 minute each time. What, you mean a UPS is no guaranteed protection? Even with the Double Conversion Online Sinewave type of protection?? (heh, got this info from http://www.sinetech.co.za/upsselect.htm) What's this voltage regulator?

    Yup. Me asking them to provide window-based DVRs, not the imbedded ones. Easier to maintain with ample spare parts locally. So, what do I do now??

    Specifying a UPS

    It's mainly to prevent the DVR from crashing. No point having it working during blackout as the cameras would be out anyway! What would it be recording?! : D Yes, of course there is a possibility that there is only a blackout at the CCTV room only but there is still power to the cameras. Well, I might want to consider keeping the DVRs working for a while until the power resumes. But it would depend on the available budget!

    Specifying a UPS

    Hello, hello. It's me- The Guest. I changed my username. So, my details of my earlier posting has been deleted by the administrator. I had inadvertently put in my fullname as my username. I wasn' t too comfortable with that. Anyway, I am back. Okay, METZ recommends 2 DVRs per UPS. I just came off the phone with a colleague from my IT Services Dept who said that since all my DVRs are in one room, it is okay to have a single UPS to protect all. So, I am still a little unsure. More inputs from any of you with UPS experiences ? Also, I understand there is this feature where upon the blackout, the UPS would send a signal to the DVR for it to do an auto log out to prevent HDD crash. What is this feature known as? Do I spec it in the UPS or in the DVR?
