Blackvue red dot?

I recently installed the Blackvue dash cam in my Model S. In all my videos I have this red dot in the videos. It is especially noticeable at night shots. I'm wondering is this a camera issue or does the Tesla have some kind of sensor that is making it show up?

Could it possibly be a reflection of the recording LED on the camera reflecting off the window? Make sure you turn off all LEDs on the camera (from the app settings).

I wonder if they had a batch of bad sensors. I have a hot pixel in that exact same spot. I purchased mine 2 months ago. For the size of that red dot, it's actually a couple hot pixels next to each other. I also have a couple other individual hot pixels (showing as green dots) but they are much smaller and only noticeable with completely black background.

That's quite a coincidence, so it's possible they have a common problem somewhere, but it smacks of bad quality control whatever it is.

Most consumer-level sensors will have a few bad pixels when they come off the production line. The manufacturer of the camera can get around this once the finished product is QA'd by running a test on the camera which will identify the bad pixels and turn them off so they aren't as noticeable. Maybe that suggests this isn't just a regular bad pixel but another component failure somewhere.

Either way, if some came out of the factory like that, it's pretty shoddy QA IMO.
