Better Technology, Better Drivers

The Encore BSD4B is a premium upgraded blind spot detection system. It uses a brand new complex algorithm based detection system to help better determine if a vehicle is actually in your blind spot, or just to the side of your vehicle. Most other blind spot detection systems simply notify you when a vehicle is next to you so this new algorithm will greatly reduce false alerts. The system includes a total of 4 sensors, 2 for the front of your car and 2 for the rear for even greater accuracy. It is also capable of detecting stationary objects like parked cars, benches and poles. The Encore BSD4B blind spot detection system will let you drive with confidence!

Why did you choose this?
Sonic Electronix Store
Talked with the designer of this product personally on the phone and got specifics of how well it would work. He was honest in stating that it's not quite as accurate as radar based detectors but was a very reliable system and the best value in cost.
Ken F on Jun 17, 2016
Meets my pricing and specs requirements.
Glenn I on Nov 9, 2015
Same price as Amazon. Good description of product.

What is the purpose of the front sensors for the Blind Spot Detecting System please ?
Niel B on Jul 14, 2015
Best Answer: Hello Niel,

The "front" sensor works in tandem with the rears to virtually establish the location of a vehicle. "Front" is a bit misleading, as you probably think the sensor is supposed to go on the VERY front of the vehicle; but in fact the sensor installs on the Side of the vehicle, which is still considered the "front" of the car.
