The TS 810 digital door viewer is ideal for house entrance doors and residential entrance doors. The door viewer thus provides more security at home - uninvited guests will have to stay away! The TS 810 has more than just a small viewer: you can see what is going on in front of the door on a 2.8" display, even when it is dark outside. This makes the digital door viewer ideal for children, senior citizens and people with impaired vision or disabilities. In addition, the TS 810 has an integrated bell with adjustable ring tone and an integrated motion detector.
