wireless solutions and products to the domestic and international wireless
telecommunications and security markets today announced the release of a
handheld cell phone detector called the Wolfhound(TM)-PRO. It is the third in

for up to 4+ hours enabling security personnel to continuously scan for all
cellular voice, text or data transmissions. The intuitive one-button
illuminated trackball allows for simple operation.

Wolfhound-PRO can also be used in countries with a mixed set of
frequencies, where US and EU frequencies are used in different geographic

targeted cell phone.

detection products from BVS. The original Wolfhound was released in December
of 2009 followed by the Wolfhound-LITE in June of last year. Combined, the
