  1. F 1.0 is a fast lens, and admits more light. The F stop is a logarithmic number, therefore each increment can produce a substantial difference, such as F1.4 is a lot worse in admiting light than a F1.2, and F1.0 is best. Generally, the cheaper the lens, or the wide the focal range, the slower the lens. You can always talk to a film camera enthusiast for more understanding of lens, and F stops. For CCTV purposes you want the lowest F-stop, and a 3x8mm F1.0 is my standard choice for most applications.

    Anyone know what this VOIP device is?

    My guess is that the govenment is trying to protect the local telephone monopoly. But then if u used voip for international calls only it would be very difficult for them to catch that. For local calls the local telephone co would be able to detect voip area codes coming in on local calls if they wanted to.

    why are you handicapping yourself with a 5x50 lens? the f stop sucks on those. move the camera closer

    Help with planning a Geo DVR setup

    I just ran an XP pro SP2 install off the CD and there was 2 choices, NTFS fast or NTFS. No fat/32, unless that option is supressed when formatting large drives (500gb)

    Help with planning a Geo DVR setup

    I checked the Geovison documentation, they recomend a seperate partition for the OS, and they recomend NTFS for both partitions. Also, on XP pro, when formatting, booting off the CD, I don't see a choice of FAT32, only NTFS fast format or NTFS.
  6. Anyone try the Samsung DVR's, like the 2162? Well featured, priced right. Comes with 750gb capacity, user changeable IDE HD's, supports dynamic IP, 120 fps, 16 channels, CDR. mpeg-4 format, remote playback & config.

    Help with planning a Geo DVR setup

    Rory, Why should the partition or drive for the OS be formatted in Fat32 instead of NTFS? I don't see FAT32 mentioned anywhere on Geovisions website. I'm not sure if FAT32 is an option when formatting with an XP cd,, i know W2K it is.

    GeoVision Drive capacity

    I am putting together a Geo 1480 PC. This is my first foray into PC-dvrs. Any limitation on the drive capacity? The motherboard will handle 9 drives (5 ide and 4 sata), so if I leave one drive for the OS, that means I can fit 8 drives x 500gb each. I'm assuming the GEo ver 8 software will see all the drives as one logical drive.

    GeoVision Drive capacity

    The mobo is an Asus P5LD2. It has the Intel Southbridge chip (4 ATA133 + 4 SATA) plus another contoller on board for 1 DMA-100 and 1 ATAPI. http://www.newegg.com/Product/Product.asp?Item=N82E16813131538 Even if some of drives gave me a problem I would throw in a low cost SATA or IDE controller in one of the pci slots as a workaround. Will be mounted in a COGEN rack chassis with a 550w powersupply. Pentium D 930 3.0 mghz/800 FSB, 2 GB DDR2-667 mghz RAM, ATI Radeon 512mb video card

    Although your FSB is a little on the slow side, not sure how much of a difference that will make.

    CCTV Camera From Pentagon 9/11

    interesting that the date & time are wrong, also the camera is mounted too far back in the housing.

    Need camera suggestions

    Rory, I don't see what the color of the camera or housing has to do with anything, especially if it's mounted indoors.

    Lens Comparison. Aspherical

    What's the F-Stop difference between the 5x50 and the 2.8 x 8? If it's F1.4 vs. F 1.0 that's the difference.

    DVR Bandwidth requirements

    I would say you would need at least 300k upload, but faster is better. If you can do 700k+ you shouldn't have any problem. Samsung GVI you can set bandwidth

    Manufacturer Comparison

    One thing I did notice about the Samsung GVI, is that you need to log in as admin to playback recorded video. That means that I had to give admin rights to everyone, and that means they can easily access the setup menu and change the DVR setup. Not a good thing.

    Manufacturer Comparison

    I called Samsung GVI support 2x last week, got right through, excellent support. But you gotta know the right number to call. They are based in Texas. ( I was pulling my hair out trying to get a remote location setup, meanwhile it was my cat5 patch cord 2 pairs were open #^%$^#@@#^@&@&)

    Samsung SHR-2162

    I've got the Samsung GVI 2162 setup and running. Not bad for the price, with 750gb capacity. Have it connected to 4 Sony day/nights box cams in housings. The unit is easy to configure, the network interface is pretty straightforward, and tech support is very good. It even comes with built in dyndns support, but I haven't tried that yet as the linksys router already has that feature.

    Alittle off topic - Perimeter alarm

    Either photo beams like Optex or sesmic sensors. I would contact a licensed professional alarm installer in your area.
