I Spy

You install home security systems for a living, not terribly hi-tech, but expensive and effective, lovely little mini cameras which feed to the local police station via the net. What people don't know is that the hardware is cheap, it's the system, the connection and the installation that costs, more importantly the switch has a minimum of 8 ports and most people only use 3-6 of them! Access to the video stream is set by port - in laymans terms that means each camera is set up differently and you control who sees what. So after 2 boring years in the job you realised how you can liven it up!

Mr. and Mrs. Smith (names changed to protect the innocent) or as you know them Simon and Debbie paid to have 7 cameras installed, you however delivered 8, but only you can see the feed from the last one.

You're working in their house, your erection is raging, but you need to work fast, where do you put it!
