The Secu-Systems solution for Perimeter protection / detection is a comprehensive onsite and remote video alarm verification and video management solution designed to provide sophisticated video alarm verification for the protection and management of site perimeters.
The site perimeters are equipped at calculated intervals with a combination of equipment which includes Flir F or SR-Series Fixed cameras, video analytics module and single channel video server providing detection and verification of geo fenced areas (analytics) which communicates to an onsite and/or offsite control room.
A typical surveillance pole would comprise of the following;
FLIR Thermal Imaging Cameras: - FLIR thermal imaging cameras are available in a range of lens and detector size options. Using a 640 x 480 or a 320 x 240 detector with lens combinations ranging from 9-100mm achieves human detection from as little as a few meters up to 1.2km's in ideal conditions. Advanced internal camera software delivers a crisp image without the need for user adjustments. It provides high quality thermal imaging in any night- or daytime environmental conditions.
Analytics Module: - The analytics module provides loop through edge based video analytics for perimeter detection purposes, effectively turning the FLIR cameras into long range detectors. Video feeds from the FLIR cameras are fed into the video analytics module, where images are analysed and processed according to a set of predefined rules, resulting in an output feed with analytics information imbedded in the video, which is then fed into the Video Alarm verification transceiver.
Analytics includes:
- Object Detection
- Geo Fencing - Virtual Fence Lines (Alarms triggered only on defined areas)
- Motion Tracking
- Zonal Notification to a Graphical Interface
- Target size filtering / Classification - minimizing false alarms and eliminating smaller or larger objects
- Loitering / Dwell Detection
A single channel network video server converts analogue video into IP-based streams and transmits this video to remote clients over LAN, broadband and mobile network. The server receives live video feeds from the FLIR cameras and analytics unit, as well as alarm signals from the analytics unit and wired detectors such as fence zones, beams or alarm contacts and transmits this information to a local or remote operator, allowing them to broadcast audio warnings and trigger remote switches in order to deter an intrusion or dispatch relevant reaction teams. The server transmits live images to a local network video recording server or DVR (Digital Video Recorder), where images are recorded and stored.
Additional Deterents:
Additional deterents can be installed to enhance any perimeter solution on verification of any would be intruders and these can include:
- Siren and or Strobe light
- Audio warnings from the Control room
- Pepper Spray Systems
- Flood Lights
Why Thermal For Perimeter Detection and Verification:
All around premises, fences and physical barriers have been installed, but fences alone are not enough, fences can be climbed and accessed easily. Even barbed wire or electric fences will not deter all intruders. We therefore need to ensure with physical barriers a complete and reliable intruder detection system, and with analytics and being able to attain crisp images both day and night, this is acheived.
Cost effective solution:
Regular CCTV cameras are of limited use for perimeters as they need a fair lighting to be effective, and associated costs with lighting and infrastructure is expensive, power points are only required at camera locations. With Thermal cameras no lighting is required and yet crisp images day and night or adverse weather conditions, the same images are produced. Not only do thermal imaging cameras produce crisp high contrast thermal images regardless of lighting and weather conditions, fewer cameras are needed to secure the perimeter when compared with that of normal CCTV cameras. This ensures keeping the overall costs of any perimeter project to a minimum, without compromising on the detection performance. Thermal perimeter systems also eleminates costly human patrols (Guards) and management thereof as thermal perimeter systems never sleep.
Reticulation:
Reticulation of the network is normally delivered with a Fibre Ring encompassing the perimter, however in certain circumstances wireless communication can also be achieved with point to point or multi point wireless transmitters and is all dependent on each individual site layout and design. The live thermal footage is then viewed at a central, on site or off site control room, however due to analytics all cameras may be viewed simultaneously or not at all and only on alarm activations does verification of alarms take place by the site controller. As all alarm activations are recorded and stored, management reports and system procedures management ensures ease of managing perimeters and controllers from a higher management perspective.
