Review on 📸 Kingslim D4 4K Dual Dash Cam: WiFi GPS, Front 4K/2.5K Rear 1080P, 3" IPS Touchscreen, Sony Starvis Sensor, 170° FOV, 256GB Max by Ray Welchhance

I have installed the front camera but I have not installed the rear camera yet. The quality and resolution of the front camera is excellent. According to the instructions, the reversing camera can be installed both inside and outside, but indoor installation is not discussed at all and the installation instructions for the outside are quite sparse. Since my car already has a backup camera, I was planning to put it inside, which would be higher and give a better view (and also couldn't be ripped off). The rear camera rotates on a plate designed to be mounted with screws that I don't want to use on my car's interior trim. I considered using velcro or tape, but the rotation made the camera bounce too much while driving. I called their support and asked what they recommend and at first I was told people usually assemble it outside. When pressed, the rep said that "usually people installed them" as if there was a Kingslim installer. She then dropped me off to ask someone else and then came back with a velcro recommendation. It was all I could do. Overall I like the front camera and feel better when it's attached. If I'm sure I can install a backup camera without damaging my car, I will. What I would like to improve: 1. The instructions are printed very small. I use reading glasses and they are still too small.2. There is no information on this model on the Kingslim website (at least at the time of writing) so I was unable to download the manual to view on a computer. Since the model isn't listed on the website, it wasn't mentioned in any of the FAQs either.3. The support team wasn't as knowledgeable about the assembly as I had hoped and honestly didn't seem concerned that the internal assembly was an issue. I felt like I should have just installed it outside and been done with it.
