I would also be interested in hearing recommendations for a dashcam installation in DFW. I have heard of other people using Speed Shield - Clear Bra Dallas and have been very satisfied with their work. I don’t have any first-hand experience with them.
I honestly can't speak/quote on their prices for their products/services, because I don't know what they are. I know they do high quality work for clients in Dallas looking for a little more attention to detail.
