How do I configure my iPhone/iPad to connect to the SanDisk connect USB device?


Please follow these steps:

  • Switch to the WiFi network created by the USB device
That's it!




Some videos stall when I try to play using SanDisk Connect USB device. What should I do?


Turn off Bluetooth temprarily on your iPhone. Bluetooth may interfere with WiFi associated with Sandisk Connect.




I'm using a SanDisk Connect device (with WiFi) and I keep getting "Empty Folder" or "Cannot Connect" messages. How to fix this?


Please use the SanDisk app to change the name of the WiFi to something simple that does not have spaces. Then delete and re-install the app and enter the name of the WiFi in the settings screen of the SentryView app.

You do not need to go to the Settings app and switch the WiFi on your iOS device manually; the app does that automatically.
Make sure that the name of the folder on the USB drive is TeslaCam. This is case-sensitive. For example, TESLACAM or teslacam would not work.




I can see the files on the USB drive on my computer, by my Tesla does not recognize the USB drive. What should I do?


Tesla requires USB drives to be formatted as FAT32. On Windows: Follow these instructions On Mac: Follow these instructions
You can also google "how to format FAT32" and find a lot of related answers. Please also watch this useful video about how to set up the USB device using a Mac.




I see "No internet connection" in the settings app when SanDisk WiFi is selected. Is that normal?


Yes, that is normal. The WiFi from SanDisk is not connected to internet. Your device is still connected to internet via cellular while your device is on SanDisk WiFi.




Do I need to unplug the SanDisk USB drive from the car to be able to use this app to view the videos?


Yes. All usb drives which have more than one interface (in this case WiFi) require you to unplug from USB before the data is available through the other interface (WiFi in this case).
This is a hardware requirement and is unrelated to the app.




How do I use a Mac to format my USB drive?


Use the Disk Utility app that comes with macOS. Make sire that you follow all the steps shown above exactly in-order. The "Master Boot Record" setting is important.

My car does not recognize the USB device. What is the problem?


Tesla requires USB drives to be formatted as FAT32 (this i not specific to SentryView).

  • You can also purchase pre-formatted USB drives compatible with SentryView app from PureTesla.com
Important: After formatting the device, you need to create a TeslaCam folder on the USB drive. The folder name must be TeslaCam and it is case-sensitive, so it cannot be Teslacam or any other variations.

During formatting, you must set the "scheme" to "Master Boot Record" (iOS requirement). See step 4 below
