Frequently Asked Questions

Can the TransitHound be used to locate cell phones?

No, because the TransitHound unit is usually deployed in a fixed position, it precludes the possibility to "triangulate" and locate the source of RF signals. By contrast, a hand-held cell detector like the Wolfhound-PRO can locate cellphones by taking two or more bearings (or, Lines of Position) of the source.
Can the TransitHound run out of power?

No, because the TransitHound does not use batteries, it derives its power from a 12-50VDC input.
Can the TransitHound store data?

No. TransitHound is a receiver that scans live for nearby cellular usage. It has a serial conenction that allows the receiver to be controlled and data to be stored on any connected PC.
What kind of antenna is used by the TransitHound?

The TransitHound can be deployed either by an Omnidirectional or Directional antenna. When deployed at large inner open spaces the Omnidirectional antenna would be used. When deployed in corridors or otherwise constricted spaces a Directional antenna could be more effective.
Does the TransitHound provide audible or visual alerts?

No but custom triggers and alerts can also be created via optional software.
Does theTransitHound identify callers or their phone numbers?

No. TransitHound is a simple, low-cost scanning device that simply triggers when nearby cellphone activity is detected. It is a wireless tool used by security officers and personnel that require a NO WIRELESS security policy.

How far away can I detect cellphones?

Typical range is about 100 feet but this varies depending upon the environment.


Can TransitHound track phone numbers or IMEI codes?

No, TransittHound only detects RF signals.


Does Transithound Cell Phone Detector detect phones that are powered off?

No but Manta Ray and SentryHound both detect phones ON or OFF even with the battery removed.
