Many of these types of cameras even have self-adjusting electronic eyes for various lighting situations.

Books and radios are everywhere and never look out of place, that’s why we have decided to carry products such as these high quality board camera digital units that can be concealed virtually anywhere. An extremely low LUX rating makes this camera ideal for low light applications, for example, our pinhole camera has a low lux rating of 0.05 which means it can almost see in the dark.
