Tesla Dashcam vs Aftermarket Dashcam Comparison

Tesla's built-in Dashcam is convenient because it uses the car's cameras and needs no extra wiring. Aftermarket systems like BlackVue or Garmin add features Tesla lacks, especially audio recording and a dedicated rear window camera. The tradeoff is power draw: hardwired aftermarket cams can drain the 12V system if you leave them in parking mode around the clock. If you just need basic evidence for daily driving, the built-in system is enough; if you want audio and higher bitrates, aftermarket wins.
