SentryHound-ProFerromagnetic Contraband Portal for Secure Facilities

SentryHound-Pro™ Ferromagnetic Contraband Portal is a dual pole (also works as a single pole) solution to detect unauthorized or illegal PEDs (Personal Electronic Devices) including cell phones, tablets, laptops, smartwatches, wearables and even weapons including guns and knives. SentryHound-Pro’s ferromagnetic inspection zones are highly sensitive to trace amounts of ferrous material found in plastic cell phones and miniaturized electronics. These same cell phones slip through regular metal detection but not SentryHound-Pro because of its sensitivity, unique motion detection and enhanced false trigger rejection. Standard metal detectors falsely trigger on all kinds of commonly used metals including titanium found in medical and prosthetic implants and aluminum used in everyday containers but not SentryHound-Pro. This allows for a rapid security checkpoint of pockets, bags, purses, clothing and even body cavities.

Use a single pole for impromptu checkpoints, doorways and wall mounted ferromagnetic inspection zones.

Use dual pole configuration (wirelessly tethered) to minimize false triggers and expand detection range over 5 feet wide.

Setup is simple and can be done anywhere – Plug and play out of the box with less than 30 seconds from powering up to full operation. No software or assembly required. SentryHound-Pro ferromagnetic contraband portal is lightweight (only 17 pounds per pole) so it can be easily transported and deployed by any security personnel instantly. Unlike most walk-through or gated metal detection systems, SentryHound-Pro detects full head-to-toe (75 inches) with light-up zones to pinpoint the area or zone of interest. The domed, omnidirectional alert is highly visible and the audible alert can be easily adjusted for maximum effect. SentryHound-Pro Ferromagnetic Contraband Portal is fully sealed against the elements for rugged indoor and outdoor use. It contains a sealed gel cell internal rechargeable battery for a full day of continuous power anywhere if needed. SentryHound-Pro also features security key lock and dry trigger contacts for alarms, DVRs, video surveillance and intrusion detection systems as well as our popular WallHound Cell Phone Detector & Deterrent.

*Every device contains different amounts of ferrous material so they do not all trigger from the same distance. SentryHound-Pro will trigger at the high end of the distance range for most every device containing ferrous material.

What does this product detect?

SentryHound-Pro ferromagnetic portal detects cell phones, tablets, laptops, smartwatches, wearables and even weapons including guns and knives.

Can I use two or more sensor poles together?

Yes. You can tether two or more poles together to increase detection range and create different configurations to protect your perimeter security.

What is standard detection range?

SentryHound-Pro ferromagnetic portal detects ferrous devices from 18 to 32 inches using single sensor pole and 32 to 64 inches between 2 gated sensor poles.

Is there any health risk for pregnant women?

No, there is no health risk whatsoever for pregnant women. SentryHound Pro operates entirely passively, meaning it does not emit any energy—no RF (radio frequency), no microwave, no ionizing radiation, and no magnetic pulses. It simply detects changes in the Earth’s natural magnetic field caused by the presence of large ferromagnetic objects, such as weapons.
Because it does not generate any active signal or field, it is completely safe for individuals at any stage of pregnancy and poses zero teratogenic (harmful to the fetus) or thermal risk.

Will it emit any sounds or pose any risk to people with prosthetic components?

The system does not emit any ultrasonic sounds during operation, except for a brief alert tone or visual indicator if a threat is detected. These alerts are purely for human awareness and are non-invasive. There is no interference or risk for individuals with prosthetic limbs, metal implants, or surgical hardware (such as hip or knee replacements, orthopedic rods, or screws). In fact, such individuals routinely pass through the SentryHound Pro without incident. Our system does not induce currents, vibrations, or resonance in metallic or composite materials, so there is no discomfort, noise, or risk to prosthetic devices.

Is there any risk for elderly individuals or those with heart devices such as pacemakers?

Absolutely not. SentryHound Pro is safe for individuals with pacemakers, implanted defibrillators (ICDs), or other cardiac devices. Many detection systems on the market today emit strong magnetic or electromagnetic fields that can, in rare circumstances, interfere with pacemaker function. SentryHound Pro does not fall into this category—it is fully passive, with no active magnetic field generation. It simply senses distortions to the ambient magnetic field, which presents no interference or interaction with medical electronics. The device complies with internationally recognized standards for medical safety and has been used successfully in sensitive environments including hospitals, correctional facilities, and government buildings where medical devices are routinely present.

Does the surrounding environment impact the performance of the Sentryhound-Pro?

Yes, the surrounding environment can significantly affect the performance of the SentryHound-Pro. For optimal accuracy and reliability, the unit should be deployed on a solid, stable surface such as tile or concrete. Avoid deploying SentryHound-Pro on carpeted surfaces. Avoid installing the SentryHound-Pro near large ferrous objects such as metal doors, ceiling fans, or any motorized mechanical equipment as these can interfere with the unit’s ferromagnetic field and reduce detection accuracy.

How fast is detection? How fast can people pass through?

Detection is immediate, but with no detections, the flow rate is approximately 30 people per minute.

How much does a unit weigh?

SentryHound-Pro ferromagnetic single sensor pole weighs 17 pounds including base.

How is this product different from metal detectors?

SentryHound-Pro ferromagnetic portal only detects ferrous material. This means it will not false trigger on commonly used metals including aluminum or titanium found in medical and prosthetic implants. This leads to less false triggering and faster, more accurate security scans.

Does this product scan head to toe?

Yes, it detects full head-to-toe (up to 75 inches) with light-up zones to pinpoint the area or zone of interest.
