We usually turn a smoke detector into a back marked cards scanner by installing inside it with a totally concealed poker camera, which can scan corresponding one-to-one back marked cards a few meters away from them.
It’s not easy for smoke detector, such a common item in public areas, to arouse suspicion from other people. Fix the smoke detector above the table on which you play poker games, turn on the poker camera before you gamble, then it will work efficiently in the cheating process: first scanning the back marked cards quickly, then collecting the cards’ information accurately, and last transferring the collected data to a backstage monitor, on the screen of which the invisible marks on the card backs can be clearly seen by human naked eyes. The data can be transmitted by wireless transfer or wifi transfer.
Your cheating partner in the backstage can let you know what he or she has seen on the monitor screen through some other cheating accessories, including two transmitters, a walkie talkie and an earpiece.
Apart from smoke detector, we can also install the poker camera into some other items like ceiling lamp, security camera and TV set, turning them into back marked cards scanners for you. If you are interested in any of them, please don’t hesitate to contact us!
