  • Are the cameras waterproof? Can the dome cameras be used outdoors?

    The outdoor bullet cameras are weatherproof, not waterproof. They cannot be submerged in water, but they can be outside in normal weather conditions. The weather that accompanies extreme acts of nature such as tornados and hurricanes will damage the cameras and this is not covered under warranty. Most dome cameras are not able to be used outdoors unless explicitly stated in their product description.
  • What is the difference between a camera with a 6mm lens and a camera with a 3.6mm lens?

    A camera with a 3.6mm lens will have a wider viewing angle while a 6mm lens will be able to view further out with a smaller viewing angle. Please view our interactive demo at for an example of the differences.
  • Can I connect multiple PTZ cameras to one DVR?

    Yes you can. There is only one connector on the back of the DVR for RS-485, but you could splice all the cables into one cable to plug into the back of the DVR. You will need to set different dip switches on each camera so that each camera has a different address. You will only be able to control one camera at a time.
  • How do I install the new system?

    The physical installation is very simple. Each camera must be wired to the power source and the video input port on the back of the DVR. Please view our wiring diagram at for more information.
  • How many monitors can I attach to the system?

    Most of the DVRs have two video outputs. One VGA and one BNC video out. When using both outputs, most DVRs will have a Main Out and a secondary out. The menu system will typically show up on the Main Out only. The 9216UVDH and the ZMD-DH-SEN6-2TB have a loopout function and can have multiple displays hooked up at once. In order to hook a BNC connection up to a standard television, you will need to purchase a BNC to RCA adapter.
  • Can I change the types of cameras that come in your kits or change the number of cameras? How do I customize my order?

    Pre-made kits cannot be edited. There are many different types of pre-made kits and you should be able to find a kit that meets your specifications. If you are unable to, you may create a custom kit on most websites using the "kit builder" option.

  • I lost my software disc. Where can I get a new one?

    Please check for the model of your DVR.
  • The DVR won't get past the initialization screen?

    a. If your DVR is unable to boot past the initialization screen or is constantly rebooting, it is recommended to check if the DVR behaves properly without the hard drive installed.
    First, unplug the DVR from the power source. Next, use a Phillips head screwdriver to un-screw and remove the top cover of your DVR. This will reveal your DVR's motherboard and HDD. Disconnect the red and multi-colored power cable that connects your HDD to the motherboard. Next, set the cover back on top of the DVR(do not screw it back on yet) and then plug in the power. If the DVR continues to not work correctly, then the issue is likely a problem with the DVR. If it acts normally, then there is an issue with the hard drive.
  • What is the default password for my DVR?

    a. The default password to the H81XX Series is 666666.
    The default password to the H80XX series is 111111.

  • How do I reset my DVR to factory defaults after I forgot my password?

    Please refer to our Knowledge Base at and search for the model number of your DVR and then the word "reset", for example "SBN4 Reset" will show you how to reset the password on the SBN4. If you do not find an article that references your system, you will need to contact our phone support staff directly.
  • I need to run cables more than 165 feet. How can I do this?

    You must use CAT 5E cable to run video feeds longer than 165 feet. You will also need to use this cable with a Video Balun. With a Video Balun and a CAT 5E cable, you can run video signals up to 1000 feet. For any run over 200 feet, please power the cameras with an individual power adapter less than 200 feet away.
  • Can I make an extension cable for the 60ft cable that came with my system? What connector should I use?

    We do not recommend doing this. It will introduce more interference and you will not get enough power to the camera. It is recommended to purchase a cable that is one continuous piece in order to make this run.

  • How do I record on motion only on my DVR?

    Please check our easy to follow tutorials on our Knowledge Base at or for the NVR, use this tutorial instead:
  • Everything is hooked up, but the monitor shows "video loss". I can't get any channels to show up?

    Please view the physical wiring again and compare it to our wiring diagram at:
    If that doesn't help, please view our quick setup guide on our Knowledge Base at:
    If neither of the setup guides help get video to show up, please use your hands to block all incoming light to the camera. The IR LEDs around the camera should light up, if they turn red, the DVR is probably defective. If the bulbs do not light up, then the cameras aren't receiving power.
  • I cannot get clear video at night?

    Usually that means there is a power issue. When night vision is activated, the cameras use substantially more power to keep the IR LEDs on. Please change to a higher amperage power supply to resolve the issue.
