Mini CCTV Screw Camera
It's a screw cam! No, not that kind...well. What you use it for is up to you, I guess. But I'm calling it a screw cam because this miniature CCTV camera looks like the piece of hardware--a simple screw just minding its own business. If you're crafty, no one will ever notice it tucked into a bookshelf or mounted to an overhead light fixture. No one will ever notice that through the threads of this screw lies the eye of a 600TVL definition video and still photo camera maker Corprit says delivers high quality images both during the day and at night.
The CCTV screw cam has a 3-pin cable with power, video, and audio ports; you'll need to supply your own power adapter and monitor. Measurements are 14mm long x 14mm wide x 19 mm high.
