Worked for about a dayReviewed in the United States on August 27, 2020
I ordered this in January but didn't have a chance to install it until early August. I followed the (very poorly translated) instructions for charging the front camera before installation, and purchased a 128-gig Vantrue card to use. The front camera worked fine, but when I connected the rear camera, the front camera would freeze up. After doing a system reset and a firmware upgrade, I still couldn't get the rear camera to power up at all. Interestingly, when I connected the rear camera directly to the power source, it powered on. So it's most likely a faulty cable. I contacted customer support, and after explaining the problem and sending pictures, they sent out a replacement rear cam and cable. After two weeks' wait, I received it today, installed it, and... nothing. No power, the front camera doesn't even detect the rear camera.Today, when I popped out the SD card, I realized that over the past two weeks, the front camera has recorded only one drive. I haven't made any changes to the setup, confirmed the power is connected and all settings are correct, but the front camera has not recorded.I'm very disappointed in the poor quality of these materials. I'd expect a $200 camera system to function properly.
