Second order of this unit

This is our second order of this unit. We wanted to increase the cameras on our truck. As usual the service was great and the delivery time was quick. I would highly recommend this unit to any trucker that wants to put a security camera system on his truck. It does everything they say it does and the video quality it’s absolutely great.
