APPENDIX A: TROUBLESHOOTING
A.1 Continuous
Tone
Alarm
The capture cards on your DVR are equipped with a “watchdog timer” that will generate an audible alarm if the cards have power but
the recording software is not communicating properly with them. The most common cause is a power surge or brown out.
•
The DVR may or may not actually be recording. Reboot the DVR by pressing the Reset button or turning power off and back
on.
•
You MUST use the UPS in accordance with installation and setup instructions. Failure to use the UPS properly will subject the
DVR to power glitches and will void your warranty if a power problem is suspected as the cause of failure. A very common
result of such a glitch is activation of the “watchdog timer.”
•
When your DVR is rebooting, always check that you get one beep per camera to verify all cameras are found.
•
If this problem continues after rebooting and you do have the UPS installed correctly, contact Image Vault Technical Service.
A.2
External Inputs Not Working
External inputs allow connection of dry contacts for the purpose of triggering video recording. Problems are either related to wiring or
software setup.
•
Check cables for opens or shorts.
•
Check pin connections to the external input jack.
•
Check sources that actuate the contact closures.
•
Check alarm input setup per Section 5.9.
A.3
Wrong Number of Cameras Recording
The capture cards on your DVR are equipped with a “watchdog timer” that will generate an audible alarm if the cards have power but
the recording software is not communicating properly with them.
•
Check cameras are properly connected.
•
Check cameras are powered.
•
If all cameras connected to the same capture card appear to be connected and powered but are not recording, contact Image
Vault Technical Service.
•
If one camera does not record, swap it temporarily with a known working camera. If the problem follows the camera, replace
the camera. If the problem stays with the input, contact Image Vault Technical Service.
A.4
Images Not Recording
(Assumes hardware setup is okay.)
•
Reboot the DVR to verify that all cameras are found.
•
Try enabling “Auto-Detect” (Part II, Section 7.2). If the recorder is still not recording images contact Image Vault Technical Sup-
port.
•
If Auto-Detect causes images to record, then you have a diff erent setup problem (such as motion not enabled). Review Part II,
Section 7.
A.5 Images
Distorted
This means poor quality image whether viewing locally or remotely.
•
Check camera connections.
•
Check camera focus.
•
Move the camera to another input. If the camera becomes clear, contact Image Vault Technical Service. If the camera remains
distorted try a diff erent camera.
•
If the problem appears on remote playback only, check the VGA settings on your PC. Insuffi
cient color depth on your PC dis-
play settings will cause images to display improperly.
