Smoking is permitted in many casinos or playing poker rooms, so it is necessary to have a smoke sensor for the security’ sake in those public places.
We fix a spy camera inside the smoke sensor to read the back marked cards in the TV or computer. Together with the wireless sender and the receiver, you can get the poker results at the distance of 50-100m, 200-300m even longer distance by using 3G/4G net.
The distance between the marked cards and the smoke sensor is 2-3m, and the camera can scan at the range of 1.5m. You can use directly AC power or battery for this set.
There are many kinds of filters for this camera. The cards for this camera can not be checked with any other cameras. If you have demand for this latest camera, it is a good choice for your successful poker games.
