The bbs-tek broadband sound back-up alarms, from Brigade Electronics, emit sound across a broader frequency than traditional reversing alarms. This allows the sound to be better detected in the immediate vicinity. In addition, these alarms emit an audible, directional hiss as opposed to a noisy, narrowband siren that can be heard in a wider but less effective vicinity, the company claims. The overall result is a locatable detection that offers minimal noise pollution. The alarms are designed to fit on heavy equipment and mobile machinery.
Also available is the Backsense radar technology reversing system. It can detect moving and stationary objects, preventing damage to vehicles and property, as well as preventing injury. The system functions by detecting the closest obstacle in the zone of coverage. Three systems are available: BS-1030 detects objects within a 10 foot radius; BS-1045 has a 15 foot radius; and BS-1060 has a 20 foot radius.
The system uses pulsed radar waves, which have a longer range than infra red and ultrasonic waves, and travel through snow, rain, mud, dirt and plastic. The system uses a 5.8 GHz radar frequency and can work on a stand alone basis or be integrated with other Brigade reversing products.
