Intruder Detection System

receiverSentinor also have a foothold in both the military and police security sector. Our award winning CobWeb range is made up of 3 unique products; CobWeb-SF, CobWeb-AT and CobWeb-MT, each varying in sophistication, technology and operational use. The CobWeb-SF is our most advanced tactical force protection. CobWeb-SF provides a GUI display receiver, GPS, low battery and tamper alerts. We also have an Android based mobile application, CobWeb-C2iM, capable of providing tactical mapping, remote communications and strategic integration.

“We use CobWeb SF with PIR and break-wire sensors with a CTR camera trigger receiver. The CTR does everything we need. Under test it has proven to be robust, reliable and with a range of multiple shots, optional timing and repeat trigger settings for the surveillance team to capture the best pictures of targets in a variety of situations. The sensors work perfectly with even greater range and sensitivity than Sentinor claimed.”

website-NT407-pendantHeritage Protection

Sentinor have been actively working with and alongside the National Trust and some English Heritage sites for the past 15 years. Our paging and alarm security systems protect National Trust sites up and down the country. Our most recent developments for the National Trust made way for our new LEGACY Pendants. The pendants are designed and engineered to be a direct replacement for the obsolete Scantronic 4601-50 style pendant transmitter and can be integrated in to any fire, security or medical calling alarm system using 173.225MHz receivers.

“I took delivery of Sentinor’s Pendants over a year ago, and have been delighted with their performance. They are discreet, yet not impossible to find, and work well as both static or moveable panic buttons. This month we tried out our old Scantronic pendants, and found that the range is much bigger on the Sentinor ones. The increase was so big that I can now walk the dogs at night, safe in the knowledge that Sentinor’s pendants are looking after us all.”
