Delta Security NI Ltd is the only company in Northern Ireland offering a Private Residential Patrol Service. This service involves patrol officers on the ground and the use of our high profile vehicles. Each residence has an electronic tag fitted to their premises which has a unique ID number. When the officer is checking the premises he swipes the tag using a hand help device and at the end of his duty the information is then downloaded to a PC and a printout sent to the client. We can also create bespoke packages to suit individual requirements.
