Tritech Omega

Tritech Omega is top of the line in phone surveillance equipment (besides owning the phone company, of course). When plugged into the phone switching box for a building, it can monitor up to 10 lines simultaneously and record up to 24 hours of conversations onto a standard datachip (8 hours of video phone or data transmission). The Omega can even listen in on and record conversations in any room containing a phone. Best yet, because the unit is self-powered and does not draw any power from the line in use, it is more difficult to detect than other run of the mill line taps.

The Omega really is all it seems to be, and more. the thing can even shunt a copy of every conversation off to another line (like yours) when the datachip is full, or fire off a burst transmission (compressed data at high speed, takes 1 minute of phone time) to any dedicated receiver. When the lines are checked with a line tap detector, roll a D10. On a 1-6, the line tap detector has failed to find the Omega. Of course, anyone going downstairs to check the phone switching box will find it (it's about the size of a Walkman).
