I added one on my MYP for extra "security"

I did the exact same thing in my model 3 to charge my phone. I have an aftermarket phone mount there.

No, there isn’t. Sentry mode is not a dash cam

No one is talking about Sentry Mode.
Teslas have a built in [dashcam](https://www.tesla.com/ownersmanual/modely/en_us/GUID-3BCC07CE-5EA2-4F40-99D1-27690898FF3C.html)

And Sentry Recordings fail to record all the time.

Always have a backup dashcam. I have one setup I like to be able to have audio too! So in case of accident or hit and run I can read off the license plate information.
Sometimes the autosave on the car doesn't fire and if you forget to honk to save or click the cam button you may lose your recording after 10m or how ever long dash cam records for

Dash cam, radar detector, or phone charger

Redundancy. I have had one in my Model 3 in the past.

The camera built in isn’t as high resolution as a purpose made one. Particularly for number plates which can be hit and miss at times. Plus the higher the resolution the better for insurance purposes.

I actually have a backup dashcam that records the screen from my other backup dashcam

It's not an OEM cable. It was left/forgotten by the previous driver.
Looks like a USB-A to USB-C cable. Maybe. I'd have to see the ends.

And I backup the backup dash cam that's backing up lol

That is what it is but what would the use case for this be? Maybe that’s a question for the OG owner lmao

Do you have the usb-a end plugged into the 12V socket in the trunk?

I have a 2020, I don’t think I have one there, I plugged it into one of the rear seat usbs. I routed it like that because I only have 2 usbs upfront, one is used for sentry and the other is used as quick access secondary charging, headphones passengers phone etc.

Well, let's think of all the common things people want to have USB chargers for in their cars:
\- Third-party dash cam.
\- Radar detector.
\- A phone mount+Qi charger to put the phone up in the eye-line of the driver.
