This weekend saw the end of British Summer Time with the clocks moving back an hour. Businesses often remember to check time changes on everything from heating systems to computers, but surprisingly they often forget to check their CCTV systems.
Keeping CCTV systems operating to the correct time may seem an obvious measure, but a snapshot survey completed after the last time clocks were changed, illustrated that many businesses are overlooking this issue. The survey looked at 300 systems and discovered that nearly one third were operating one hour ahead or behind the actual time or had other timing related issues.
The survey findings were quite surprising particularly given that the timings on CCTV systems are a critical. An incorrect time can result in problems searching for video evidence and events, especially if these are tied to times from other sources such as till receipts or ANPR (Automatic Number Plate Recognition) collection. Where a system uses recording or alarm schedules it can mean that the CCTV system is not giving users the alarm response coverage they expect.
Another key point to bear in mind is that the CCTV system may be using recording schedules, which change the record or quality patterns of the CCTV system at different times. If the CCTV clock is not adjusted, critically, the record schedule will also be incorrect. Likewise, an alarm schedule may dictate when alarms can be triggered on the system, this is especially important in the case of sites where alarms are fed back to an RVRC (Remote Video Response Centre), as they will not receive alarms at the expected scheduled times.
There are CCTV diagnostics software that can automatically run system time checks and this increasingly is being specified as a mandatory requirement by Alarm Receiving Centres and their customers. These tools can ensure that timing issues can be identified automatically and immediately addressed. This is not necessarily the case with manual or physical site inspections where, sadly, incorrect time settings may not be discovered for weeks or months.
A few minutes checking to make sure your systems are set to the right time, could save hours of work in the event of an incident.
