Abstract
A surveillance data recording device includes a display, a digital tuner, and a control mechanism. The display displays a received surveillance data signal over a first bandwidth. The control mechanism allows a user to select a frequency band of interest. The digital tuner truncates the received signal to produce a narrowband signal comprised only of portions of the received signal that are within the frequency band of interest. A digital storage unit, such as a fixed or removable hard drive or solid state storage device, stores the narrowband signal over a period of time.
