What makes this "Spy Watch" different than others on the market? This one point - the intelligent mounting of the camera results in the image being correctly orientated when the watch is upside down, so the picture is always perfect when you are naturally resting your arm on a table. As any pro can tell you, with most watch style hidden spy cameras the video ends up being upside down and needs a lot of editing to make it viewable. This this model we have done the smart thing and put the camera in place so that you can rest your arm and get the video right the instant you record it. This spy kit also comes with an advanced wireless DVR having a 2.5 inch LCD and a one touch button for instant recording onto any inserted SD card. This 2.4GHz 4-channel video signal receiver uses the latest in wireless signal technology to make sure you can capture all the action clearly at a resolution of 640x480 and with a frame rate of up to 30FPS.
