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 You Need This

  • Keep your vehicle and your passengers safe on the road
  • According to the National Highway Traffic Safety Administration (NHTSA) there are approximately 840,000 side-to-side blind spot collisions in the United States annually
    • Out of these 840,000 collisions there are 300 fatalities
  • Why risk messing up the paint job on your shiny sports car?
  • Why risk messing up ANY kind of vehicle you drive?

General Features:

  • Premium upgraded advanced logic blind spot detection system

    • Algorithm determines when a vehicle is in an actual blind spot rather than alerting you every time a vehicle is next to you

  • Installs in virtually any modern vehicle using a 12V electrical system
  • System comes with 4 sensors with anti-false trigger logic
    • 2 front sensors and 2 rear sensors
  • Provides visual and audible aid

Looks like a good item for my truck
Curtis W on Nov 22, 2017
I have a 2017 Dodge Ram 2500 sits high I am hoping this will help
Belinda B on Apr 18, 2017
It was recommended by a Fiat blog...hopefully it will work as advertised. thanks
Oscar S on Oct 24, 2017
Looks to be a complete system. Just what I was looking for.
Frank S on Dec 20, 2016
How does this system compare to the Goshers premium (4-sensor) system? They look identical, even down to the text on the dip switches of the control box and the alert speaker. I want the best aftermarket blind spot system available, but I don't see a point in spending more than double for different text on the control box.

The Encore Blind-Spot Detection & Assist System - BSD4B looks exactly like GOSHERS BSDS-003016P.

Are they the same items with different names?

Is there a car compatibility list?

hello, does this system alert without using blinkers?
lee s on May 20, 2016
Best Answer: The system I have has lights that go on without using blinkers. If the blinkers are on then there is an audible alert. Unfortunately it doesn't appear to be confined to the blinker being used, right or left. So, if your right blinker is on and the left light goes on, there is an (unnecessary and disturbing) audible alert. Furthermore, the system is not reliable - is gives many false alarms, and in many instances fails to alert. So, add this to the blinker question and you may get an audible alert for nothing, or you may not receive an alert when it is necessary. I don't feel that the system I have has problems due to the install. I feel that I have a defective unit, either by virtue of a quality issue, or by design. Either way, this issue remains unresolved some months later.

A shopper on Apr 19, 2015
Best Answer: Hello,

If you are not familiar with the installation process we highly suggest attempting it. Below is a link to the literature that the manufacture provides.

Will this work for a front blind spot too? I constantly am missing pedestrians if they're in my front blind spot and they're going about the same speed as the car.

Can this be used in a big straight truck like a 26' box uhaul?
A shopper on Nov 21, 2017
Best Answer: I think it should work... but u may need to extend some wires in between the module and the display... I don't think it a better idea is using cameras and multiple angle display.
