Description

Hunter is a professional wireless detection and location system for search teams operating in prisons, government facilities, border environments and other high-security locations. It helps operators rapidly identify wireless activity, narrow search areas and locate the source of detected transmissions.

Why security teams choose Hunter

  • Survey wide, then pinpoint. Sweep a whole wing or site with the omnidirectional antenna, then switch to the directional or probe antenna to track a signal down to the room, cell or hiding place.
  • More than phones. Detects cellular (2G, 3G, 4G and 5G), Wi-Fi and Bluetooth activity, including short bursts such as SMS texts and data uplinks.
  • A record of every detection. Each detection is logged with time, date, frequency, signal level and network provider, and can be downloaded as a daily log file.
  • Passive and discreet. Hunter only listens: it never transmits. Earbuds and vibration alerts allow silent operation during searches.
  • Configurable for any country. Frequency bands are programmable from 400 MHz to 6 GHz, and band updates are delivered by email and loaded via the supplied USB drive.

Applications

  • Prisons and correctional facilities: cell searches, wing sweeps and locating contraband phones.
  • Government and secure facilities: checking restricted areas, meeting rooms and SCIFs for unauthorised devices.
  • Border and perimeter security: surveying large outdoor areas, with up to 300 m outdoor detection range.
  • Investigations: building a timestamped record of wireless activity for follow-up.

Features

  • Detects cellular, Wi-Fi and Bluetooth activity
  • Long-range wireless detection capability
  • Survey large areas quickly
  • Locate signals using directional antennas
  • Detect 2G, 3G, 4G and 5G devices
  • Frequency filtering and attenuation controls
  • Detection logging and record download
  • Built for operational search teams

FAQs

Does Hunter identify callers or their phone numbers?

No. When regional profiles are used, Hunter can identify the service provider of the detected signal, but not the caller or number.

Can Hunter detect more than one phone at a time?

Yes. Survey mode identifies multiple phones using different sections of the cellular spectrum.

How far away can Hunter detect a phone?

Up to 175 feet (53 metres) indoors and up to 1,000 feet (300 metres) outdoors. Range depends on the strength of the target signal and on the surrounding environment.

Does Hunter detect phones that are powered off?

No. A phone that is switched off is not transmitting, so it cannot be detected.

Can Hunter detect text messages as well as voice calls?

Yes. Hunter detects and logs all transmissions, including short bursts such as SMS texts.

Can Hunter detect smartphones browsing the internet or using data-based calling?

Yes. Hunter is designed to detect TDD data transmissions, so it can tell data uplinks from downlinks, a first in handheld phone detector technology.

Can Hunter locate a phone, not just detect it?

Yes. With the directional antenna, the signal bar peaks when Hunter is pointed towards the source. The probe antenna can be slid under the door of a room you suspect contains the phone.

Does Hunter transmit any signals?

No. Hunter is a receive-only detector. It does not transmit.

Can Hunter be used silently?

Yes. Alerts can be delivered through the supplied earbuds and the built-in vibration feedback instead of the speakers.

How long does the battery last?

Over 5 hours of continuous operation, with an 8-hour charge from empty. Hunter can also run on mains power for continuous monitoring.

Can Hunter be set up for a different country’s mobile networks?

Yes. Frequency bands are programmable anywhere from 400 MHz to 6 GHz. Band and software updates are sent by email and loaded using the supplied USB drive.

Can Hunter units be networked together?

No, but for fixed, networked monitoring take a look at Watchman™.
