Future
Installation & Remote Monitoring of Detector Activated CCTV Systems
• Detection area should fall within the field of view of the cameras
• Dual technology detectors when facing boundaries, adjoin roads, playgrounds, public footpaths to reduce unwanted alarms
• Detectors should be adjustable in both horizontal and vertical axis
• Tamper circuits to detect e.g.– Opening by normal means– Removal from mounting– Orientation adjustment– Tamper circuits must be continuously monitored

BS8418 2010 Review
• Now covers wireless & semi-wireless detectors• Low battery• Loss of wireless signal• Individual identification of detector in these
conditions• Consideration should be given to positioning
detectors facing away from the boundary• Wireless detectors also offer a very good
solution to positioning detectors on the outside of a perimeter

BS8418 2010 Review
• 10 detector wired system: alarm, tamper, anti-mask & power requires 4 pairs per detector
• Potentially 16 terminations per detector – 160 in total
• Wireless system: loss of signal, low battery, tamper, alarm & anti-mask minimum 5 pairs per detector
• 20 terminations per detector – 200 in total

Future
Conventional Wired vs Digital
• CP249 open protocol• Up to 32 detectors on 4 core cable• RS485 bi-directional comms• Addressable detectors• More alarm states possible: back & front
tampers, supply voltage & RF signal strength
• Remote diagnostics, check settings, make adjustments remotely
• Install time reduced – less site visits
