Mobile Phone Security Monitor


PocketHound Info Pic 1PocketHound™ is the industry’s most sensitive mobile phone detector for it’s size.  This award-winning*, passive receiver is no larger or heavier than a deck of cards and specifically tuned to the RF signature of common mobile phones (both U.S. & international bands) including all 2G, 3G and 4G bands (PCS, CDMA / WCDMA (UMTS), GSM, EGSM).  This breadth of band detection allows any security personnel to locate nearby mobile phones in either standby mode* or during active voice, text or data RF transmissions making it the perfect tool for enforcing your NO WIRELESS security policy.  PocketHound prevents unauthorised mobile phone use by detecting nearby (up to 75 feet indoors) mobile phones all from your pocket.  PocketHound’s auto threshold feature automatically detects mobile phone mobile phone activity only above the RF noise in your environment.  This prevents false triggers and alerts the user to any mobile phone activity with bright LED flashing or vibration for completely covert, in-pocket detection.  PocketHoundis designed and manufactured in the U.S.A and is the perfect device for courtrooms (jurors and court personnel), classrooms (stop cheating students) and boardrooms (prevent corporate espionage) as well as prisons, government secure facilities and military installations.

PocketHound Reviews

“I immediately began successfully detecting hidden cell phones. Being in the Criminal Corrections field, this product is a great tool to have. This product delivers at every level, it is small enough to conceal, easy enough for just about anyone to use properly and accurate enough to trust. Also, this product has worked so well for me that I have recommended it (imparticular) to others working in my field. Great job BVSystems!”Lead Captain Michael Biddle

“I ordered it due to the low cost and the ability to conceal. I use it in a prison setting and have not found any cell phones to date and didn’t expect to as my facility is very clean as opposed to others. I do know the PocketHound works because there are two employees here that are allowed to carry their cell phones inside with them and whenever I am in their vicinity and have the PocketHound on me, it does pick up their phones. This assures me that it works and will pick up a phone if one is ever in the area I am using it.”

Michigan Department of Corrections


“[PocketHound] used in mustering prior to shift change, 2 officers had cell phones on them and were possibly going to take them to their duty stations, and the Pocket Hound detected them and they took them to their vehicles.”

Warden Michael M. Johnston
Blair County Prison


“We use ours in the booking area of the Jail. That way everyone coming into the secure area has to walk by where the PocketHound sits. We also do rounds in the jail with the device to try to detect any cellphone activity in the pods.”

Sheriff Neil Miller
Buffalo County Sheriff’s Office





Frequently Asked Questions

Does PocketHound identify callers or their phone numbers?

No. PocketHound Mobile Detector is a precision RF cellular scanning device that identifies mobile phone activity (both standby mode and active modes) and assists in locating them. It is a wireless tool used by security officers and personnel that require a NO WIRELESS security policy.

How far away can I detect mobile phones?

Typical range is about 75 feet but this varies depending upon the environment.

Can I detect phones in standby mode?

PocketHound can detect phones in the standby mode but keep in mind when a phone is ON in standby it is not constantly transmitting. Phones register to the local cell tower/base station at different intervals that the tower/carrier determines (could be every so many seconds, minutes, 5 minutes, or we have seen 20 minutes). When a phone registers it is a short pulse less than 1 sec so the BLUE LED will light up quickly and vibrator will not vibrate because the pulse is so short. Easy test is if you take your phone and put it next to PocketHound and shut off your phone completely wait a few minutes then turn the phone on your phone should try to register to the base station and you should see a short flash on the pockethound.

Will PocketHound work in a noisy RF environment?

Yes. PocketHound has an auto threshold feature that scans the local RF noise floor in order to identify mobile phone energy just above that level. Auto threshold may also be manually adjusted by the user.

Does PocketHound Mobile Detector detect phones that are powered off?

No. A phone that is turned off cannot be detected by PocketHound.

Can PocketHound detect text messaging as well as voice calls?

Yes; as long as the RF transmissions are made over the prescribed frequency band(s) the PocketHound receiver will detect them. However, since text transmissions tend to be short and intermittent (as opposed to voice or conversation which is more continuous), the user would have to pay undivided attention to the PocketHound alerts to catch text messaging activity.

Can PocketHound only detect mobile phones or can it locate them as well ? If so, how?

PocketHound can both detect and help locate cell phones. The internal antenna has some directionality built-in along with a series of visible LED signal strength indicators on top of the PocketHound. This gives the user the ability to hone in on the nearest mobile phone activity without having to move closer to that mobile phone.

Can PocketHound stimulate a mobile phone to transmit RF signals?

No, PocketHound only detects RF signals; to stimulate a mobile phone it would have to transmit RF signals, which would violate FCC regulations and guidelines.

Can PocketHound track phone numbers or IMEI codes?

No, PocketHound only detects RF signals.

Can PocketHound units be networked together?

Currently, the PocketHound is available as a stand-alone, pocket-sized unit only.
