Unitech develop a completely solution BSIS (Blind Spot Information System) to comply with the UN ECE requirement of UN R151 for commercial vehicle (M2, M3, N2, and N3). BSIS System consist of two built-in radar PCBA to provide full 180° coverage of the vehicle’s side blind spots. Which effectively detects obstacles within the entire blind spot area. MOIS System use a microwave radar to detect obstacles in front of the vehicle. During startup or low-speed driving, the system provides warnings for potential collision hazards (such as bicycles or motorcycles in front of the vehicle at traffic lights, or pedestrians or bicycles/motorcycles crossing pedestrian crossings). The whole system is the perfect solution to fulfill the regulation requirements of both UN R151 and UN R159. ![](https://superunitechsensor.com/wp-content/uploads/2024/12/PSS-%E9%92%BB%E7%9F%B3%E5%A4%96%E5%A3%B3%E9%BA%A6%E8%B7%91%E6%98%BE%E7%A4%BA%E5%99%A8%E7%89%88%E6%9C%AC.png) ♦Features \*Moving-off Information System(MOIS) and Blind Spot Information System(BSIS) combination kits, uniform alarm display and harness, with more competitive price, save installation time, highly performance cost ratio； \*OEM & ODM service available according to customer’s requirements； \*External output：trigger other warning device； \*Self-diagnosis alert to driver； \*High performance millimeterwave radar module； \*Long range detection distance, can detect the pedestrians more than 45meters in the open area； \*Wide detection angle，horizontal angle can reach 140°- 180°； \*Excellent small blind zone to 20cm； \*High reaction ,and refresh time in 50~100ms； \*Identify stationary or moving objects； \*Flexible radar installation angle adjustable； \*Metal radar bracket with strong radar housing makes the sensor more stronger and stable; \*Multiple waterproof design, internal with [teflon](http://The reason to add this teflon is, while the sensor working, it would create a lot of heat, then the air inside would expand, but after stop working, the air become cold, the size of the air inside sensor would become small, at this time, the outside air would be sucked into the sensor, if without this teflon, the air might come from the cables and connectors, this will result in connector PINs rust, with this teflon, the air would come into sensor via it, and the moisture will be blocked outside the sensor.) ensure the high performance of waterproof; ◊ Multiple function display with integrated form \*Showing with obstacle position and distance,; \*Built in buzzer and volume adjustable; \*High brightness LED display,  no afraid of reflection, stronger indication makes the driving more safer; \*With setup function; \*Tracking led display with runway appearance; \*Tracking led display integrated with showing and alerting, makes installation more easier and convenience. \*High reliability and stability, display with CAN communciation ensure fast signal transmission and strong anti-interference ability. \*Suitable for both road-going and road-off applications. ◊ With Handheld setup tool to adjust detection area freely \*More easier and convenience touch screen setup tool, eliminate the trouble of installing software on the computer and the inconvenience of setting up; \*Detection length and width settable; \*Bootup customization optional. ♦ MOIS Radar Specifications ITEM Parameter ITEM Parameter Rated working voltage（V） 12V /24V Traceable target numberMAX 31 Operating voltage range（V） 9-36V Horizontal angle（°） 140 @ -3dB Working current ＜200mA Vertical angle（°） 20 @ -3dB Operating temperature range（℃） \-40 ~ +80℃ Angle accuracy（°） ±0.5 @ 40° Storage temperature range（℃） \-40 ~ +85℃ Angular resolution（°） 15 Working frequency（GHz） 77G Distance Accuracy（m） 0.1 Transmit power（dBm） 12dBm Distance Resolution（m） 0.1 Modulation mode FMCW Waterproof grade IP67 Antenna form 2TX，4RX ♦ BSIS Radar Specifications No. Part Name Qty 1 AHD camera 4 pcs 2 AI Monitor 1 pcs 3 Extension cable 5m x 3, 10m x 1 4 Main cable 1 pcs 5 Installation kit 1 set ♦ Tracking Led Display Specifications ITEM Parameter Rated working voltage（V） 12V/24V Operating voltage range（V） 9-32V Working current ＜500mA@12V Storage temperature range（℃） \-40 ~ 85℃ Operating temperature range（℃） \-40 ~ 80℃ Volume ≥90dB@12V/10cm
