We installed a mini spy camera inside the bulb. You can scan the whole poker table to see the number and suit of playing cards by adjusting the position or angle of bulb. What I want to note that you should cooperate with your partner in the poker games. When you are in the poker room, your partner can be in other places and see the playing cards by computer or cell phone and tell you the scanning result. If the position or scanning angle is incorrect, you can use wireless remote control to adjust it. This poker cheat device can be used in private poker clubs, Blackjack, Omaha and other poker game you play.
