  • Are Contraband Cell Phones Endangering Your Correctional Facility?

    Yorkie™ detects active 3G/4G/5G cellular use up to 150 feet away. Touch screen & vibrating alerts allow for covert surveillance by corrections & law enforcement staff requiring a NO CELL PHONE policy in their facility. Yorkie supports optional direction finding antenna for pinpointing cellular use up to 1/2 mile away outdoors. The passive receiver does not intercept cellular data so no court orders or warrants are required to operate and perform cellular tracking in the field.
