3.5" TFT Color LED Portable Test Monitor CCTV Camera Security Tester for Surveillance Audio Video Input

This little monitor is great! So far, any connected camera, whether using an RCA connector or a coaxial connector (including an adapter) or even a direct USB connector, will detect them and provide clear and clean images. Even after I dropped the damn thing a few times. I installed the monitor on an electric wheelchair and connected it to a very cheap spare camera. My neck doesn't turn, so I can see behind me. Going back is dangerous for our cats, dogs, grandchildren and all kinds of wild animals. The display provides 12 volts to the camera and captures its yellow video through its red RCA female connector. I am attaching a photo of the result.

Great for adjusting a surviving camera. In the past, I had to climb the ladder and look down, look at the screen and do it again. Now I use the monitor and upload it only once. If you think the camera is not getting enough power, the boot option is fine.

Like KKmoon CCTV Tester 3.5" TFT color LED wrist display, the effect is very good, like it. Thank you for purchasing it is a good purchase, thank you again!

Long battery life. Easy to connect, high quality housing.

I bought it 1 year ago. You can top up at any time. Use every day, never flop.
