11.0 TESTING

11.1 INITIAL SYSTEM TESTING

Before using the newly-installed surveillance system, do the following:
• Make test recordings at the time-lapse speeds you will be using. Test how the
system performs with alarms.
• Interrupt electrical power to check your installed power backup system (if ap-
plicable).
• On playback, verify picture quality and that you can see the time/date display
under normal and alarm conditions.

11.2 REGULAR SYSTEM TESTING

Every day check that the system is operating. Is the REC indicator lit? does the
COUNTER display indicate movement? Does the monitor show proper camera
sequencing and time/date information?
Check for recorded alarms. Multiple alarms could make the tape run out early. Make
sure there is enough tape to record at least five minutes of alarm activity at the
selected speed.
Regularly verify picture quality and operation under normal and alarm conditions.
Play a tape recorded recently under normal conditions, which also includes an
alarm condition that you triggered manually.
Regularly replace tapes (refer to Table D for a schedule). Check tapes for head
scarring. Replace damaged tapes. Always store tapes in their boxes; away from
magnetic fields, heat, direct sunlight, and dust.
