Mobile surveillance units like this one cost at a minimum $53,900 and come with four pan/tilt/zoom (PTZ) surveillance cameras, remote controls and monitors that can be accessed from anywhere in the world via internet. Optional add-ons come at additional expense and include automatic license plate readers; sirens; two way speakers; infrared cameras; extreme zoom cameras that can see human beings up to 1 mile away; motion detectors; and satellite communications. Wanco, the company that manufactures this particular unit, tells us that DHS and “many government agencies” are among their clients.
