"Here’s a new undercover color camera designed to fit into the proliferation of personal devices (PDA’s, cell phones, MP3s, etc.) that seem to be everywhere these days.
The camera’s pinhole lens aims out of your ear, perpendicular (90°) to your target, allowing for high angle above the neck mobility. The camera has 350 lines of resolution and a super low 0.6 Lux for evening observations.
The 3.6mm lens gives you a sharp 78° field of view. Includes a hardened case, rechargeable battery pack and charger." (more)
