Hi guys, looking to install a blackvue 900 dashcam in my car. I've read on a couple threads from 2018 that Tesla will show a service battery message if the camera's wired directly for parking mode. The workaround I saw was buying blackvue's battery that plugs into the 12v in the console. Was wondering if it's still necessary? Thanks.

No. It was a "yes" prior to Sentro Mode but not since Sentry Mode.
Sentry Mode keeps your constant 12V going so there is no longer need to get a portable battery.
Unless, of course, if you turn off Tesla Sentry Mode then your 12V would time out and you would still need a portable battery.

A'-Lo-HA ! y'all
Tam, But just to be clear, the Blackvue needs to be plugged into the power port in the console? And not wired directly to the battery?

Correct.
Your dash cam should be plugged into Model 3 cigarette lighter outlet in the console. And that outlet used to be timed out prior to Sentry Mode but now, you can turn on Sentry Mode and that outlet is no longer timed out.

1) Sentry Mode was not implemented so people had to buy their own portable battery until that mode was released.
2) Now that Sentry Mode is released, it drains quite a lot of battery so some might want to use their own portable battery instead.
3) Some homes are nudist colonies so they don't want to turn on Sentry Mode at home until the society is more open.
Oh... I think I misunderstood the question. The question is why not using Sentry Mode instead of going through the trouble of adding duplicating dash cam?
I would say since Tesla Cam is still in beta so it may work in one firmware but then broken the next... and also Tesla only has video not audio, and it doesn't display the rear camera view (directly rear, not talking aobut side rears) ... so it is prudent to add a non-beta dash cam with audio for your Model 3.

Tam: Would the dashcam drain the 12V battery if in parking mode ? I am thinking of adding the dashcam too, but was worry about draining the 12V battery
I had a blackvue battery before sentry and no longer use it. Maybe it's a defective, but the battery remains at full charge with sentry and no longer powers the dashcam.
