This harmless looking key fob could be just the thing you’ve been on the lookout for, after discovering some lipstick marks on your man’s collar that do not belong to you because you don’t use Bobbi Brown’s Light Warm Beige semi-matte lipstick. Unfortunately, you lack the hard evidence to bring your man back to his senses, so having this Key Fob Video Camera/DVR with you could be the perfect fodder. After all, you can discreetly place this at a bedroom or living room (or where you suspect the tryst is going on), letting it record videos or snap images that are stored on its 2GB internal memory. Video quality stands at 355 x 288 resolution at 15fps, while images are 1.3 megapixels clear. You will get up to 150 minutes worth of video recording with this, and 2GB will also net you 4,000 still images. It will cost you a handsome £395 (including taxes) to bring this home though.
