Review on 🚚 Wireless Backup Camera for Trucks with 5'' Monitor, DoHonest S23 HD 1080P Bluetooth Backup Camera for Car Van Camper - Stable Digital Signals, Supporting Additional RV Camera. Built-in Wide Voltage Range of 12V-35V. by Aaron Villanueva

2. Second check The system sucked at first so I contacted the company for help. They sent me a new wire extension antenna which didn't help much. But after emailing them again asking for help, they sent me an updated camera which greatly improved the signal from my truck and trailer to around 99%. I was very disappointed with the system but this company did everything in their power to rectify the situation. This was the best customer service from the Revain seller. Now I am very satisfied with the result of the system. I recommend contacting them first if you have any questions. Excellent work. Many Thanks.
