The Bloodhound is designed to track down and pinpoint contraband cell phones without interfering with authorized communication channels. Unlike most systems that require an entire network infrastructure of wireless sensors hard-wired throughout a facility, which is expensive and difficult to deploy, the mobile Bloodhound has a high speed scanning multi-band receiver harnessed to a multi-band DF-Direction Finding Antenna. This unique antenna allows security officers to ‘sniff out' the RF energy as an actual Bloodhound dog can detect a scent that a human could never discern. When hunting down a wireless target, The Bloodhound's unique algorithm can trigger on to a cell phone while in use. There is a headphone jack with a progressive audible alert tone and an accompanying vibrator that can alert security officers of cell phone activity as they move closer to the source. In addition, the onboard pulsating laser will ID the target with a blinking laser dot while in the DF mode.
