Damn, that's more than I was expecting. Doing some quick math, thats around 250-300 W of power consumption to have 3 cameras running. Agree it sounds like basically the car isn't going to sleep in this mode then. I've estimated previously that the phantom draw is around 60-70W, so this is about 3.5x the idle draw of phantom mode.
I guess its nice to have the feature, but I do think its a bit wasteful for running 3 cameras given that a dash cam maybe pulls 1A/5V, so 5W. That includes the writing to SD card in the dash cam, and usually also for powering a small LCD screen....So in my simple mind I would expect 3 cameras to add less than 25-30W of 'overhead' to the idle draw of a model 3. My 'quick' estimates and reality aren't always in alignment, but it seems excessive to me still

Maybe you are forgetting that it isn't just three cameras running. It is using the AP computer to analyze all three camera feeds, and other sensors, to detect bad acts and turn on the screen/lights/horn/etc. Not to mention that the USB stick is hooked to a different computer, so that computer and network has to be up and running as well. So you have two full blown computers, a network, and a dedicated GPU unit running for Sentry mode.
It isn't a purpose built dashcam that was designed for low power consumption.

You're still going to use it regardless, what's 300W's compared to a damaged door/panel?

Anyone knows if the Saved Clips from Sentry Mode will be automatically overwritten or not ? What happen if the USB drive get filled up ?
Parked at work today for around 9 hours and with Sentry Mode on, it chewed up about 2.5% of battery.

Doesn't appear to overwrite. I noticed my recording red dot is gone this morning. Time to pull the USB and see what's on there

Hope this is something they are going to fix in the future. For the time being I may need a 2nd USB key for backup ...

Just got the update today. Looks like Sentry mode only records from 2 side and 1 front cam. For some reason I thought it was doing a 360.

Same thing happened this morning to me. Recording dot was off. Didn’t have a chance to check the key but seems like a glitch.Doesn't appear to overwrite. I noticed my recording red dot is gone this morning. Time to pull the USB and see what's on there
