As part of a BJA project I'm helping an agency try to find policies and procedures related to cellphone detection devices. If you have policies related to the BVS SentryHound (tower similar to the Metrasens Cellsense/Ultra) and/or PocketHound, or Wolfhound (cellphone signal detectors) that you can share, please let me know. If you prefer to work directly with the agency, I can facilitate that.
