Since the S1 Pro Max dashcam comes with a weather sealed 4K rear camera, I was very eager to see what the video feed would look like with the camera mounted externally. It would eliminate the terrible rear dash and window glare that I'm getting and the result will fill the frame with a full rear view from the car rather than giving me half a frame of trunk lid and rear dash. I did spend some time removing a few trim pieces from the exterior of my trunk and looking for a relatively easy way to run the USB cable from the outside of the car to the inside. The cable on the rear camera has a 15mm wide USB plug on it. That's a pretty large hole that needs to be drilled, then you need to find a mounting grommet that is "just" the right size. Then it needs to be caulked.
I didn't have a suitable place on my car to accomplish this, so I did a quick and dirty external mount using the clear static mounting sheet and just ran the cable in through the trunk lid for a quick drive. The USB cable itself has a 5mm diameter, which is a pretty substantial cable. Instead, I just ran the cable back into the trunk, clamping the cable with the trunk lid. This is less than ideal and I only wanted to leave it for a short time period so it didn't deform the trunk lid seal. Here is what the mounting looked like:
There was plenty of room on the overhang area of the trunk, right next to my backup camera by the rear license plate. The mounting mechanism works well, but the thickness of the cable makes it rather stiff and inflexible. This made it somewhat difficult to achieve and maintain the desired positioning of the camera. As I adjusted it, the spring in the cable pushed it back out of place again. After some fiddling around, here is what I ended up with.
Anyhow, here are two videos that I made with the rear facing camera mounted externally. I have to say that I REALLY like this view and I enjoy the unobstructed field of view that it provides. VERY NICE! The perspective is a bit lower than being mounted at the top of the windshield, but I really like this view and the lack of window glare. It's just too bad that I can't keep the camera there. With a ribbon cable or other suitably thin cable, I would definitely leave the camera on the outside of the car!
Edit: Ha, the camera picked up some Classic Yes that I was listening to while I drove. Surprised youtube didn’t flag it for IP…
A few thoughts and suggestions for
@Jeff_Vantrue
- the cable that exits the rear of the camera sticks straight out. Because the cable is relatively stiff (due to thickness) the camera needs too much space behind it to accommodate a bend in the cable. This limits mounting positions.
- is it possible to use a flat ribbon cable instead of a 5mm diam round cable for the rear camera? This would facilitate easier mounting, either by running the flat cable under a trim piece or just clamping it down through the lower trunk seal. In the second case, I could probably run the cable down behind my license plate and then just run the thin cable across the trunk seal without much risk of water intrusion
- maybe also consider a flat USB connector as well (just a blade that fits into a USB connector like some USB string lights use), rather than the bulky oval one that is used. This will make sealing the connection to the rear camera cable with heat shrink more difficult, but will better enable easier external mounting.
- i would be very willing to test a prototype flat cable rear camera for you
🙂
Here is an example of a thinner USB plug from an LED strip. Not perfect, and it’s a USB-A example, but thinner would be better. If Vantrue could make a thin cable mount for the rear camera, I’d leave it there forever!
A little thinner than this would be ideal
👍 Then I could tuck it under the trunk release mechanism without risking much water intrusion during the rain.
