With v1 or any other radar detector, u should mount them high, ie near rear view mirror. Mine gives plenty warning for any foward facing camera, and tells me the rear facing one. Just drive 10 km above limit if ur in a hurry u will be fine, rear ones has bigger tolerance than front facing.

Laser jammers should have high power rating and effective coverage to jam tripod, and cover ur headlight and number plate. And they r illegal, so u want one with a kill switch to prevent u jam a laser gun for too long.
