The OSU (Optical Sensing Unit) injects Infrared Laser pulses into Fiber Optic Mesh and it detects Optical echoes of the Infrared Laser pulses caused & backscattered by a cutting or excess force when an intruder pulls or cut off the Fiber Optic Mesh.  The ACS (Alarm Control Station) which is located at MCC (Main Control Center) receives the intrusion data from OSU and generates the audible alarm and pinpoints the intrusion spot.

(2) No Gaps, no compromise - 100% detection • FOM sensor do not compromise and overcome all the limitations of Vibration sensors (3) Accurately locates within 15m • Pinpoint to the exact location of breach for effective security management. • The human eyes have limited night vision range and only able to see up to 30m in twilight. • As such, the PIDS must be designed to address this human limitation and be accurate to pinpoint intrusion within the 30m accuracy. • With Fiber cable sensor, the accuracy is about the 200m range and this definitely not acceptable as the patrol is unableto reach the specific intrusion point to see and apprehend the intruder. 7 (4) Applicable unlimitedly by fence type and terrain condition • FOM can be mounted on any type of the existing barrier or free standing whereas other kind of systems is restricted to the type of existing fence. • For example, vibration cable sensors cannot be fitted onto a loose iron mesh fence or a rigid wall. • It can be only being applied on a high-strength iron mesh fence because the cable sensors require to sense the sound or vibration when the intruder cuts the mesh or scales over the rigid wall. (5) FOM is the effective measure against digging. • FOM can be applied without limitation by terrain condition providing effective anti-digging measures. Shallow digging can be effectively detected by inserting FOM bottom to Grooved Rod top in soil base ground condition. (6) Negligible Maintenance • For FOM Sensor, minimum electronic equipments are placed outdoors and does not need any adjustment or calibration to cater for weather change, hence the system requires negligible maintenance. Unique & Cost Effective perfect Solution - 2 8 (7) Reduce CCTV Cameras • With conventional PIDS such as Cable Sensor or Microwave, with accuracy if about 100m, fixed cameras must be placed at 50m spacing or PZT cameras at 200m spacing for effective coverage. • On the other hand, using FOM Sensor with the ability to pinpoint intrusion with an accuracy of 15M, PZT cameras can be placed at spacing of 400m. This will mean significant savings in the cost of CCTV system required to work effectively in conjunction with the PIDS. (8) Save Security Lighting • The site under protection by FOM Sensor does not need to have Security Lights ON at night unless intrusion happens. • No intrusion no nuisance alarm allows no need to have security lights. • Instead to have Security Lights ON, illuminators with cameras are preferred to illuminate at intrusion scene at alarming by FOM.
