Gazelle™ is designed from the ground up to provide hot-swappable receiver modules for in-the-field installation and includes an internal 12-channel/satellite GPS receiver.
Gazelle supports 120 MHz – 6000 MHz (CW only) with the following module choices in stock. Custom bands also available:
120 – 180 MHz, 6 / 12 kHz IF BW, 250 Hz step
400 – 512 MHz, 6 / 12 kHz IF BW, 250 Hz step
690 – 960 MHz, 6 / 12 kHz IF BW, 250 Hz step
800 – 960 MHz, 12.5 / 25 kHz IF BW, 250 Hz step
1700 – 220 MHz, 6 / 12 kHz IF BW, 250 Hz step
2200 – 2700 MHz, 6 / 12 kHz IF BW, 250 Hz step
3300 – 3800 MHz, 6 / 12 kHz IF BW, 250 Hz step
Gazelle’s unique, modular high-speed receivers exceed the distance based averaging required to meet standard and 40 lambda averaging criteria essential for critical propagation analysis. The Gazelle is a low-cost test system ideal for advanced pre-buildout drive-studies for optimizing WiMAX and LTE networks.

Does WallHound-Pro identify callers or their phone numbers?
No. WallHound-Pro is a passive RF cellular scanning receiver and deterrent that identifies cellphone activity (both standby mode and active modes) and alerts security personnel. It is a fixed wireless device used by security officers and personnel that require a NO WIRELESS security policy
How far away can I detect wireless devices?
Typical range varies based upon the device and if optional direction finding antennae are used. Bluetooth devices can be detected from about 50 to 100 feet away. Wi-Fi devices can be detected from about 100 to 150 feet away. Cellular devices can be detected about 125 to 250 feet away. These numbers vary even more depending upon RF interference, environment, line of site, placement/installation of unit.
Can I detect phones in standby mode?
WallHound-Pro can detect phones in the standby mode but keep in mind when a phone is ON in standby, it is not constantly transmitting. Phones register to the local cell tower/base stations at different intervals that the tower/carrier determines (could be every few seconds, minutes, and we have seen up to 20 minutes). When a phone registers, it is a short pulse of less than 1 second so the WallHound might only flash once and play the audio alert once instead of continually.
Can WallHound-Pro be networked to other devices or security systems?
WallHound does not contain any wired or wireless networking hardware such as an ethernet port but it does contain a USB port for firmware upgrades. This port is only accessible when the security key is used. WallHound-Pro also includes dry contacts that allow it to be triggered from other detection devices such as our SentryHound-Pro.
