Portable Digital Video Surveillance System

Model DVSS-6

 

 





The DVSS-6 is eentec Surveillance’s third generation controller module utilizing current state-of-the-art technology with field proven design concepts. It has been adapted to control up to 6 wireless cameras and monitor up to 7 vibration sensors.

The DVSS-6 Digital Video Surveillance System is a low power, portable, modular system consisting of a controller unit, vibration sensors, power source, and wireless cameras. The controller unit consists of a state-of-the-art microcontroller that acts as the “brains” of the system. It manages the menu driven user interface, signal conditioning and amplification, triggering of the system, power management, control of the DVR module, and wireless camera transmitter and receiver modules. The entire controller unit is housed in an environmentally sealed rugged lightweight engineered plastic case intended for burial. An external battery or batteries power the controller unit, allowing the flexibility of desired operational duration in the field.

The signals from the vibration sensors are band (frequency) limited from 20Hz to 50Hz. These are the frequencies of interest generated by a subject moving within the target area. Lower or higher frequencies will not trigger the system thereby limiting the possibility of false triggers generated by background noise.

The wireless cameras are in a cylindrical PVC housing with sun visor. They are powered by their own power supply via a small wire running to the battery or batteries that are buried. It has no connection to the recorder, so the recorder location cannot be determined in case of camera detection.

The system is designed to add future options such as remote alerting via cell or radiophone and digital sound recording.
