Home > Case Studies > Case Five System required to allow a police dog carrying out a search to send back visual information to it's handler The Problem The existing systems were heavy, cumbersome, uncomfortable for the dogs to wear and limited in range. There was a need for a versatile, lightweight and easy to use dog mounted camera system with an improved range, more dynamic operating range and effectiveness. It had to be robust while lightweight, simple to operate but effective in a demanding environment, able to operate in low light conditions, provide clear video feedback in buildings with obstructions such as walls and remain operational for the duration of the mission. The Solution The FIDO system addresses the above problems with a simpler, more user-friendly design, which reduces the weight carried by the dog by over 75%. This enables the dog to negotiate steep downward slopes without danger of overbalancing and also considerably reduces fatigue. The system comprises a miniature television camera and radio transmitter mounted on a lightweight head harness. There is a quick-release facility, allowing the harness to be worn at all times the dog is operational if required whilst the camera is attached only when needed. Rechargeable batteries, able to provide power for 2 -4 hours, are contained in a collar, the attachment of the camera to the harness automatically making the required electrical connection. To allow operation in darkness, infra-red lights are incorporated in the camera housing, and provide pictures in total darkness to a range of 3-5 metres from the dog. An audio facility can be provided if required, allowing the handler to listen to any activity in the area of the dog. Pictures are viewed on a combined video recorder/monitor/receiver unit carried by the handler. This unit is provided with a neck strap and waist belt to allow easy mobility whilst leaving the hands free. |
