Are you a warden of a small-town jail, or maybe an raging film theater chaperon who’s sick of ungrateful patrons interrupting Step Up 3D since they can’t be worried to spin of their handsets? Cellphone jamming is, for the many partial, still out of a subject, so Berkeley Varitronics has introduced the small something called the Wolfhound. Previously well known as the Bloodhound, the device lets you file in on RF signals, that equates to it won’t help you if phones have been powered down, though if your perp has one on standby, or if they’re articulate, texting, or surfing the web, you’re golden. Interested? Of course you have been! Hit the association up for the price allude to — but not before checking a video after the break.
