I'm very excited about this product, and I'll be at a SOS demo tomorrow to see if this system will meet our needs. We currently have CanTrol and it is not just a light and siren controller. It, like bluePRINT, is complete vehicle integration. Ours is completely tied into the patrol vehicle, powering everything from dashcam, radar, radios, etc.. With the help of CanTrol, the car radio is shut off and broadcasts the police radio over the car speakers while only in slide switch 3. Hitting your brakes while running lights and sirens changes patterns and siren to phaser with Howler for 3 seconds. Hitting brakes without anything on has the tail light vertexs "flicker brake".
There's a K9 vehicle now being installed and the CanTrol is integrated into everything from the AC, windows, and pop door.
I'm sure this is can all be done with bluePRINT too and is why I'm excited. I'm no fan of CanTrol due to its cost and complexity (cars go back and forth for weeks to the installers to work out bugs); I'm just pointing out the system is much more then an expensive light and siren controller.
