Has your CCTV been tampered with?

We’ve all seen Hollywood movies and TV dramas showing criminals tampering with CCTV systems prior to committing the crime.

Admittedly, they’re often pretty far fetched, but there are methods used by everyday criminals or disenfranchised employees to tamper with CCTV systems and leave them vulnerable.

Here’s 5 ways that your security system could be compromised through tampering, and how to detect that it is happening…

  1. Disconnected Cameras – A pretty basic one, a CCTV system can’t record what it can’t see. If the power or video cables can be seen by a would-be criminal, they can be disconnected. Check that cameras have not been disconnected from the system, especially ones around opportunist targets such as POS areas or Staff exits.
  2. Camera Tampering – As a camera that is disconnected produces an alarm condition, cameras are often moved, obscured, or otherwise tampered with to ensure the system is not recording the criminal activity. Check that the cameras are pointing where they should be, and the image is not obscured or blocked. It’s worth taking a snapshot reference image from each camera and comparing against that.
  3. Time or Date Adjustment – Adjusting the date or time on a DVR may be used to cover up a crime being committed, or at least make it difficult to find. Check that the time and date is accurate, there may only be a few minutes discrepancy either way, but that’s all it takes.
  4. Disarming the system – Some CCTV systems may use a keyswitch or timer to Arm or Disarm the alarms – especially if it is being monitored remotely. If a system has been accidentally (or purposely) left in a disarmed state then it may be leaving the site vulnerable. Check that your RVRC is receiving alarms from your site at the expected times.
  5. Disconnecting Alarms – If the site connects to a central monitoring station on alarm activations, damaged or disconnected alarm sensors can leave the site vulnerable by not signalling alarm triggers back at the central station. It could be many days before the central station realises that alarms are not triggering. Again, check that your RVRC is receiving the expected amount of alarms.

If you think it seems like a lot of work to check that your systems have not been tampered with and make sure they are working – you’re absolutely right, it would take a huge amount of resource to conduct these tests even once a day.
