Sentry Mode - USB Data Storage

It appears Sentry mode created a subfolder titled “SavedClips” and stores potential threat recordings there. Most of these recordings are of motion (I.e. people walking by in a parking lot). Curious, as my USB drive gets full, will Sentry Mode automatically write over older files? Details on Sentry Mode data storage would be appreciated. Thanks!

    Good question — see this related thread in the Model S forum: https://forums.tesla.com/forum/forums/problem-camera-fills-thumb-drive-and-then-stops

    Thanks. My guess is that Sentry Mode will fill USB drives fairly quick because all data is located in the “saved” folder. I plan to get a few USB drives and just cycle through them. I love the advice from experts here. Keep it coming!

    After parking with Sentry Mode in effect, the car records a good deal of footage. That doesn't bother me. But i notice that after each such session that I have to remove the USB drive and scan and fix it before the system will use it again. This seems like another bug similar to the one they had when they started recording on the USB drive. Anyone else notice this?

    I haven’t noticed that. I get multiple ‘sessions’ from Sentry Mode.

    Filled up a 16gb memory stick in about a day and a half of testing Sentry Mode. Parked on the street, and a parking garage. It seems everything (cars driving in front of it, tree branches etc,) sets it off. Had to remove it and delete everything.

    I replaced the 16gb usb thumb drive with a 500gb external usb drive. Will let it run for a week and i'll see how that goes.

    Hello, I was wondering if I have to buy a USB or does the car come with the usb installed? If I have to buy one, where do I put in the car?

    Thanks

    You have to get one. I recommend at least 256 GB I have a 500 GB installed and it uses about 12GB per day with sentry mode on always. Create a folder on it named TeslaCam (case sensitive) Plug it into the first usb port. And thats it.

    Sorry a new owner here -
    1) 1st USB port, which one is that one?
    2) Does it need to be a special USB stick (perhaps one with High Endurance which are meant for repeated video recordings?
    3) Does the USB stick need to be pre formatted?

    1. Either of the front 2 ports are data and power, use one of those.
    2. Get at least 256GB USB 3 drive as they are fast at writing and endurance really doesn't matter these all can handle a lot. If you are going to use Sentry mode get 500GB drive.
    3. Yes look at DashCam in manual and format accordingly as well as create the directory it is looking for.

    @alfoguacor - Picking the right USB drive will help make it work right, or picking wrong one will give you an ulcer with various odd problems. This comes up so often, I wrote a detailed guide to picking the USB drive: https://teslatap.com/articles/usb-flash-drives-for-tesla-dashcam/ as it's more complicated than most realize.

    Also, you should expect the drive (if high quality) to die after 1-2 years (128 GB). Cheap drives will last a lot less. The larger the drive the longer it will last. Small drives might only last a few months.

    @asterix007 - Most drives 32 GB and smaller are correctly pre-formatted. Drives > 32 GB are almost always the wrong format and must be formatted for FAT32. My guide in prior post shows you how to format on WIndows and Mac, as it is not straight forward.

    On Sentry mode, there is a bug that once the drive fills up with Sentry mode video, the dashcam stops recording any video. I expect Tesla to fix this at some point, but for now, you'll need to periodically delete the Sentry Mode video from the Dashcam. WIth 128 GB, perhaps every 2-6 weeks. It varies because it depends how much motion occurs while in sentry mode. For a car parked in a home garage, it will store far less video than a car parked on a busy street every night.

    This 128gb sandisk is formatted correctly in the box. Add the TeslaCam folder and plug it in.

    First Sloflo the Model 3 only has USB2, so a USB3 drive will work but not get the added benefit. Look for the blue tab vs black in the USB devices.

    2nd, you might want to buy a USB hub so that you don't lose your USB charging. You can plug in the USB FOB and the charger cord into the hub.

    @sloflo, can I use the 1TB or 2TB or even bigger external HD for Sentry mode (as long as I got it format to FAT32)? I don't use TeslaCam. this HD is solely for Sentry Mode only.

    Tesla service told me today that regardless the size of the USB drive it will get filled with sentry video and requires a manual clearing using your computer.
  • edited March 2019
    yes eventually any size would....it's all about the duration between cleanings! At least until they change the software to wrap around in a smart way.

    I ended up putting a fat32 formatted 750GB hard drive, yes a spinner! Approximated 4W, max 5W, I probably gather it uses around 3W continous.
    Make use of that thing, velcro'ed it to the side wall in the bin.
    USB music on a partition on the drive too, USB scanning for files is much faster and remembers last audio place! With the flash drive, it took too long to scan so it never remembered what it was playing.

    @kallian I'm using a 490 GB SSD formatted with two partitions (Video/Music) that I placed in a USB case (total cost $70). All of my USB problems have gone away. Music and Video have worked flawlessly since I installed it. I suspect there was a seek timeout occurring on slow thumb drives.

    @jvcesare can you describe your setup in detail with model nos?
  • edited March 2019
    FYI - if you need a 500GB portable SSD drive for sentry mode, get the sandisk extreme portable drive for $68 from Sandisk directly. Not sure how long the sale would last. Just bought one for myself.

    Hello Everyone, i am new model 3 owner and love it. Did someone tried to put video format on external usb/hdd to play on the screen or its just capable to play music only?

    The Model 3 cannot currently play video on the screen. Even if you use the web browser and navigate to a video site it will not play. I suspect this is for safety reasons.
