Repair the Cause, Not Just the Visible Symptom
A commercial security failure is not always caused by the device that appears to be malfunctioning.
An offline camera may be affected by:
- Damaged cabling
- A failed PoE port
- Insufficient switch power
- A network-address conflict
- A recorder configuration problem
- Failed surge protection
- Moisture exposure
- A defective camera
- An undocumented network change
A controlled door may not secure because of:
- Strike alignment
- Damaged electrified hardware
- A failing power supply
- Door or frame movement
- Incorrect programming
- A door-position switch problem
- A reader communication fault
- Controller or network failure
An alarm trouble condition may involve:
- A low backup battery
