I think air conditioning is the best cover to hide IR marked cards camera. There is an infrared receiver for its own remote controller, so we can take use of this infrared receiver to install the juiced marked cards spy camera.
The set of air conditioning IR poker camera including a lens, one transmitter, one signal receiver and a pair of bugging earpiece. Because of installing position, normally we recommend you the IR lens that cannot zoom in and zoom out. Because of this, it would be easier to install.
There are two ways for you to receive the cheating result image. First one is connecting the transmitter and receiver with wires. You can see the cheating outcome on a monitor on the next room, downstairs room and the upstairs room. And the second way is using radio waves to transmit and accept the message. In this way, you no need to use the wires to connect the transmitter and the receiver. And if you want to enhance the signal, you can use a bigger transmitter. And the structure of the air conditioning supports you to use a bigger transmitter.
If you want to see the whole poker table and avoid some possible condition that would affect you see the poker trick playing deck, you need to find a nice place to install the air conditioning. It would be perfect if the air conditioning is on the back of banker.
As I say, air conditioning is a best way to hide the invisible ink marked deck camera for its structure and size.
