MAINTENANCE
The Vantage Video Detection System, once correctly installed, requires a minimal amount of maintenance.
Camera Cleaning
Because Vantage video detection is a machine vision based system, one of the big operational concerns is
keeping the front camera glass reasonably clean. A regular maintenance program should be implemented to
ensure the front camera glass is kept free from dirt and debris. The camera housing glass should be cleaned
at least once a year, or more frequently if required, especially under severe environmental conditions. Dirty
camera glass is one of the leading contributors to decreased Vantage system performance. The use of a soft
cotton cloth (non-abrasive) and water is the recommended method for camera glass cleaning. Avoid leaving
streaks on the glass. Avoid anything that might scratch the glass, cloud the glass, or leave an undesirable
residue.
Connector and Cable Inspection
Periodically, it is wise to check camera power and video connections. Look for connector corrosion or
moisture damage. Replace any defective connectors. Cabinet power and video cable and connections can
also be checked for excessive wear or other defects. Repair or replace the defective cable or connectors as
needed.
