When wearing these sun glasses the hidden video camera lets you record exactly what you are looking at. The hidden hardwired color CCD camera built into these trasparent lents sunglasses has a 92° field-of-view so you will not miss any action. You simply run the small wire down trough your shirt or jacket and plug into your own digital recorder or small camcorder. You can place the included battery pack in your pocket or even in a back pack or gym bag with your digital recorder then leave the glasses on top. Cool portable video for fun or covert work. A tiny video camera is hidden inside a pair of sunglasses. Great for private investigators and law enforcement.
