I would strongly recommend installing your 4k Blackvue Dashcam for some of the following reasons;
- Sentry doesn't save recordings unless you click on the icon, or use your horn if you have set this option.
- The recording of the four cameras is sequential so you miss a lot of information, not like the separate front and rear constant recording on a dashcam.
- The Sentry image definition is blurry for anything more than six feet away, you cannot read license plate unless a car is very close to your bumper.
- The Sentry recording is not reliable, sometime the recording stop for no reason.
- There is not speed and sound recording.
Some of the Sentry bonus or issues are:
- The side camera is a nice feature, however I would had preferred that the B pillar cameras were used instead of the side fender because if someone hit you on the front side, like passing a red light, and run away, you cannot see the action and the license plate.
- You can access the Sentry live cameras on your phone, including the inside camera, but you cannot access the Sentry recoding from you phone.
Note: Blackvue video can be accessed from the Cloud, but you need to have a Hotspot inside your car or use the WiFi in your garage.
- You cannot select some recording areas when parked, like for the Blackvue, so sometime your Sentry will get triggered a zillion of times because there is a fluorescent light facing one of the Sentry cameras.
Sentry when running prevents the car from going to sleep mode. However you can get a constant 12V from the ODB2 plug
even when the car is sleeping to run your Blackvue all the night without affecting too much the car consumption.
You don't need to use a 12V battery voltage limiter, like Blackvue provides one, because if the 12V battery voltage gets too low
the DC/DC inverter will starts to charge the battery. However I would not keep my Blackvue running all the time, like when parked in an airport.
Still the Blackvue has a sleep mode which gets activated after five minutes of no motion.
When installing the Blackvue, there is no 'Ignition On' wire on your Tesla but this feature is not needed because if you just use the 12V auxiliary plug, this plug will turn off when the car is sleeping.
Note: The newer Model Y has a 16V lithium-ion battery and I don't know if you will need to use a buck converter,
