Q:
When I test my connection under System -> Hostname, I get an error message saying:
  1. "Interceptor connection failed. Your DVR successfully connected to the Internet but your network setup or security settings are preventing people from connecting into your DVR. Verify that port 5005 is not behind a firewall and that your router has port forwarding to 192.168.XXX.XXX."
  2. "Network timeout. Could not connect to the Internet. Your network settings may be incorrect, or a cable is unplugged, or your Internet connection is not working."
  3. "Register failed (Duplicate name server found in database. Please try again.). Contact service provider."
A:
  1. This error is caused when port forwarding is not setup correctly on the router. Please refer to the port forwarding section in Section 5.9 of the Installation Guide for further assistance. Some ISP networks, such as Verizon, will still display this message even though the network is working. If you have followed the port forwarding guide and are still getting this message, please contact technical support for further assistance.
  2. Do the following steps:
    1. Double check to make sure that the cable is plugged in. If you have a computer connected to the same router make sure you are able to get online with that computer.
    2. Check to see if you have the correct network settings under System->Networking. Refer to Section 5.9 of the Installation Guide for help.
    3. If you are still getting this message, try connecting to the DVR locally by opening up Internet Explorer and entering in the IP address of the DVR that shows on Settings->Status page into the address bar. If you are not using the default web port 80, then you need to add a colon and the port number after the IP address. I.E. http://192.168.23.125:81/
    4. If you are unable to connect to the DVR, then the DVR is not on the same network as you or a cable is unplugged somewhere.
  3. A server with the hostname you are using is already in our database. Change one or more characters on the hostname on the DVR (System->Hostname) and click Test. Remember to save your settings.

Q:
My video feed is distorted, washed out, or has flickering artifacts.
A:
If you are experiencing video that is distorted, washed out, too bright, colorless, or erratic, you probably have video signals that are not operating according to proper video standards. These problems could be caused by malfuncuntioning cameras, overpowered or underpowered cameras, bad video connectors, or cabling that is poor quality, old, corroded, or extended over long distances without the use of repeaters.

It is useful to have a CCTV test meter that allows you to check the quality of your video signals. If your video signals are out of spec, they may still show up correctly on some monitors or devices, but they may be of lower video quality, and their behavior may be undefined on other devices. A CCTV test meter will accept a video input and let you read out levels for different attributes of your video signal, including sync pulse, white level, color burst, and vertical interval levels. You can move the meter up and down your video cable until you identify the source of the problem. Here is a description of the different attributes of the video signal and how they will affect video quality on your DVR.

  • Sync Pulse: Sync pulse signals are used to signal the start of every new horizontal line. The sync level should be at 40 I.R.E +/- 5 I.R.E. A low sync signal will result in a picture that breaks up or rolls. If the sync signal is too high, the picture will experience loss of definition and dynamic range.
  • White Level: The white level controls the brightness of the video signal and should be 100 I.R.E. units +/- 5 I.R.E. A low white level will dim the image, and a high white level will result in a video that is bright and washed out. If you are mixing cameras on your DVR with different white levels, you may experiencing flashing brightness artifacts on your video display.
  • Color Burst: The color burst level encodes the chroma portion of the video signal, and should be 40 I.R.E. units +/- 5 I.R.E. If it is too low, colors will be faded, or your DVR will revert to black and white.
  • Vertical Interval: The vertical interval occurs at the gap between video frames and should be 40 I.R.E. units +/- 5 I.R.E.

If possible, you should avoid mixing different types of cameras with different signal levels. If you must mix different types of cameras, group similar cameras on the same capture card (a capture card is a column of 4 BNC connectors)

Q:
I am seeing vertically scrolling horizontal lines on my video feed.
A:
You probably have a ground loop on your video cable.

A ground loop is an electrical problem caused by a voltage difference between the ground located on the chassis of the DVR and a ground on the camera or video cable. If you are seeing a horizontal bar moving vertically through the video display, you probably have a ground loop. Ground loops can cause video distortion, and if severe enough, can cause stability problems or damage to your CCTV equipment.

Ground loops can occur because the reference ground signal in one room or building may be different than the reference ground signal in another room or building. Your DVR is grounded at the point where it plugs into the wall for power. Your camera or video cable may be grounded at a completely different location. The voltage difference between the two grounds causes a current flow that leads to interference in your video signal.

To prevent ground loops:

  1. If possible, do not connect your camera or video cable to ground. Your camera will be grounded through the DVR.
  2. Power all your cameras from the same power source, and make sure this power source is plugged into the same outlet as your DVR.
  3. Avoid contacts between your camera and metal or conducting materials on your building. These conducting materials may be connected to the earth ground.
  4. Make sure your video cables are undamaged and shielded.
  5. Avoid placing cameras and video cables in close contact with high power lines.
  6. Avoid cameras that use certain types of AC power transformers. These transformers can introduce ground loops capacitively. If you find that a particular type of camera leads to ground loops, you should avoid that type of camera in the future.
  7. If you are still experiencing ground loops, you can purchase a video isolation transformer that is designed to eliminate the effects of ground loops.

Q:
What BNC port is camera X?
A:
Channel one starts on the bottom left of the capture cards and continues across cards. That is, channel one is on the bottom closest to the monitor plug and the next channel would be on the bottom of the other capture card. If you have a 16-channel unit, this is what the camera order would be:

Q:
When I save changes under the schedule tab and go back to check them, the settings are reset.
A:
The software is not recognizing the changes. The system software needs to be reinstalled to fix the problem. After that, the settings will start saving.

Q:
My DVR is not recording even though it is set to record in the schedule tab.
A:
Check the recording type under Schedule. If it is set to record on motion, make sure there is motion in the cameras. If there is motion in the camera, check the motion masking under the Settings->Motion menu. If all the boxes are tinted blue, then all the motion is being masked out. If there is no masking and/or the record type is set to continuous, reinstall the Tsunami software.

Q:
I am getting a black screen from my TV/CCTV that is connected to the S-video port.
A:
Any monitor connected to the S-video port has to be connected to the DVR, turned on, and set to the right input before the DVR is turned on. Some CCTV's have a high/low switch on the back, which needs to be set to low. If your CCTV does not have one and you are still not getting a video feed, make sure that your TV has a 75-ohm termination.

Q:
All my video feeds are scrambled, and the DVR is asking for a license.
A:
The video license is missing on the machine. Contact technical support at 1-877-7TEMPEST and a technician can issue you a new license. Please have the serial number off the back of the unit ready along with the key that the screen provides.

Q:
I'm trying to use the remote control but nothing is happening.
A:
If the IR receiver is blinking, try changing the batteries and reboot the system. If the IR receiver is not blinking, make sure that the IR receiver is plugged into the back of the unit. Once it is plugged in, reboot the system and try again.
