    CCTV 13.8VDC Power supply

    check the voltage at the camera you should not have a problem wth the 13.8 as most cameras will operate withing a range of votages. Check camera specks.

    build my own VMS server question

    On geovisions website you can download the vms manual and it has a list of tested motherboards and chipsets. I would stick with one of those if posssible.
  3. you can connect using the equipment but you wil need some kind of nvr software. You should be able to find some free demo versions if you are only going to be using it for a couple of days. why don't you take some photoes that are time stamped to prove you were not picked up? seems like less fuss
  4. Does your NVR manual state how big of a harddrive it will support?

    Two CCTV cameras look like this

    it could simply be the cameras have taken a surge or something has just gone out. How old are they and how much to replace

    Two CCTV cameras look like this

    Are these IP or analog? I would disconnect one and see if it makes a change in the other. Are these run on the same cable . say different airs on a cat5 cable with baluns. If analog are they using the same power supply. Have you checked voltage at camera and the connectors.

    Coax to Fiber to IP to Coax?

    I would go to a fiber to cat IP and get new cameras. To muddy the waters you can get a converter to run ethernet over coax. My goal would be to have the fewest converts etc as possible. Ip cameras are cheap enough now that ditching the old analog ones should not be that expensive

    CCTV camera Interference Help

    I would run a seperate feed for each camera. check your voltage at each camera. disconnect each camera and add them in one at a time using a known good power supply.

    Android based camera working with Windows pc.

    you can get programs that will allow you to run android operating system on win ten i have one called Bluestacks. works for most Android apps.
  10. Geovision has a ( popup camera function) that changes the default view when motion is detected on a camera. We had this setting at a city hall where all cameras were viewed but when a certain camera detected motion a full screen view of that camera was on the screen for a certain amount of time. I am not sure but I think you can have multiple cameras come up at once.
  11. I guess and extender would be a passive device but your idea would work I thought of a switch (not knowing the physical layout) would work as you would only have to power up one device as opposed to several injectors.
  12. if these cameras use standard POE you may need to placce a switch or extender in the 300 ft range to mantain power. There are extenders to go beyond the 300 ft range but one switch may be cheaper.

    Cat and Cat5e?

    check your local electrical code as cca may not be allowed. Agree with the poster who suggests putting in spare runs. I was in the cabling business for 14 years and neve had a customer say they were sorry that the cable they needed for a new device was all ready installed.

    Cat and Cat5e?

    just checked cat5e is around 14 cents per foot. solid copper at that price why mess around with susect cable? Hoe much do you plan to save?

    Splice COAX to split the feed.

    you could, if you had a spot monitor output. I as guessing their might be some distance issue so the powered splitter would solve that problem. When we are talking about splitting the cable we are talking about BNC connectors on all the cables?
