@Vol,
In theory, you can set the camera up at home on your personal WiFi network and configure it to record to the microSD card. Choose Record events only, and it will then only record video to the SDcard when motion is detected. Set the Detection zone to whatever is appropriate to capture the alleged thief. The camera will then record video in 1-minute ‘chunks’, saving to the SDcard any minute in which motion was detected. Once the camera is configured for local recording, you can relocate the camera from home to the office and connect it to power. It will power up, and start recording to the SD card when motion is detected.
I say ‘in theory’ because there is a known bug in the camera firmware. The camera will stop recording after about 1.5 hours if it is not connected to a WiFi network. It’s not supposed to stop, but that’s what it does. The bug has been acknowledged by @WyzeTao at Wyze, but the ETA for a bug fix is unknown.
More information on the topic along with a workaround can be found in this thread:
One caution on the above recipe - there are reports of SD cards becoming damaged in the cameras, sometimes permanently. Some have suggested that this might happen if power is disconnected from the camera at the instant that it is writing video data to the SD card. To guard against this, it might be best to put the camera in a quiet place (i.e., where it is not seeing any motion), wait at least a minute, then pull the power. That will reduce the likelihood that it will be writing to the card when it loses power.
If you’re keen to put the camera into ‘full service’ at the office (and you won’t jeopardize your employment by deploying hidden surveillance technology), there are ways to get the camera on-line that accommodate the company’s authentication procedure.
