I purchased the Nexus 4 Pro a month ago and had it installed. I am so pleased with my choice to install cameras and my choice for Vantrue. In this environment where large format vehicles dominate the roads, too often I suffered aggressive behavior by other drivers. However, I am very sure that installing the cameras has changed that. Drivers seldom tailgate me and they no longer cut me off. I think when they get close enough and they see the camera in the rear window, they know they’re being recorded and they moderate their behavior. If they aggressively, cut in front of me, I have their license tag documented. I also like that the cabin is recorded, and I like that there is a small remote control that I can quickly tap to snap a picture. I like being able to download images without having to remove the storage card thingy🤣. So this has been a surprising benefit to me. I mainly intended to use it to document any accident while driving or damage to the car while parked and unoccupied. I highly recommend this Vantrue and Nest 4 Pro.
