The Harbor Dynamics SuperCam is crowdfunding on Kickstarter. The portable gadget combines a security camera with a power bank. The 1080p camera can capture video, images and sound, which you can store locally or have automatically transferred to your phone. A power bank has a total output of 140 W with a 100 W USB-C port and 10 W wireless charging pad.https://www.notebookcheck.net/SuperCam-discreet-security-camera-power-bank-2-in-1-device-has-100-W-charging.640167.0.html
I have heard that FHD is not enough for that security work, but the idea is interesting.
