overview The D-Bolt Electronic Bolt System is a new and innovative security system to protect expensive and/or sensitive equipment against theft.
How it works D-Fence's Strain Gauge Sensors are embedded into bolts and screws of different calibers and then connected to an electronic box containing a PC Board card connected to a Wireless transmitter, a GPRS transmitter, an SMS system or a GSM system and to contacts. Any attempt to open or loosen the bolt/screw generates a warning and sends its location.
Installation and Maintenance One screw/bolt with D-Fence's strain Gauge Sensor is installed into the equipment to be protected, replacing any common bolt. The system operates on the same battery for years (stand alone), and does not require any routine maintenance.
