*See if the camera is physically enabled, gets power, and re-check the RS232 connections. You can also test if the camera is physically enabled by covering the light sensor on the rear camera '''(marked green in the picture below)'''. The rear camera’s IR LEDs should turn on by doing so in a dark environment.

*If the camera seems to be enabled, check the SD card content. See if there are any files and review the footage using TF CardVideoPlayer v1.14. If there is some footage from the time the camera was turned on. The actual time in the camera might differ, therefore check older dates to see if there are any videos.
*If some recent video files were found, it means that the camera is working, but not responding to RS232 commands. Otherwise, the camera is either not working or not responding to commands and does not detect SD card.
