This project requires stringent security with the given terrain constraints of a very vast cleared land with a step gradient, surrounded with dense jungle and vegetation. Vdosoft was specially engaged to consult, design and provide a secured environment for the memorial park of the Late Tan Sri Lim Goh Tong.
The technologies used are Active Infra Red Beam Detectors and specialized CCTV cameras integrated with infra red floodlights. This ensures optimized viewing possibilities during day and night times The perimeter technology chosen for this particular scenario is Active Infra Red Beam Detectors. Although passive Infra Red Motion detectors would have been a common choice, these devices DO NOT perform well under outdoor conditions based on tropical climates, where rapid temperature change is inevitable. We have chosen beam detectors with high immunity to environmental change and with a beam detection range of 25m ~ 75m. Each Pole is further equipped with a Power Control Unit that rectifies and regulates the incoming low voltage 48VAC to DC voltage that is utilized by the various electronic devices on the pole. The Power Control unit is also equipped with a standby battery power and has the ability to signal the Control room during any power failure. Each pole is also equipped with a wireless 868 MHZ telemetry system that monitors for any breach in the perimeter beams. Integration of strobe light at the poles gives instant visual confirmation of the area under duress.The proposed CCTV system has two primary functions. The first is to act as a backup perimeter detection system using Video Motion Detection (VMD) technology. The second is to fulfill its objective as a surveillance camera. To achieve both these requirements, we have chosen a high resolution B/W camera with Wide Dynamic Range ... [continues]
