Thumb Stick Controller
The IR Patrol comes standard equipped with a multi-directional fully ruggedized, weather-proof thumb stock control. The thumb stick is large and easy to find in the dark and is much quicker and easier to use than conventional buttons found on nearly every other thermal system on the market.

QCM - Quick Command Mode
Quick Command Mode(QCM) is featured in all models of the IR Patrol. QCM is a an extremely advantageous tactical feature that is completely user configurable. QCM allows the user to configure 4 icons as seen below, each of which is controlled by the movement of the thumb stick controller in that direction. QCM allows you to configure each location to which ever icon you choose. If you want the same icon in all locations, you can do that. These icons are set by moving the thumb stick in the direction you wish to set while holding the thumb stuck in that direction, each button press will change the icon type. Once you have the icon you desire, release and you are done. The thumb stick featured on the IR Patrol is the easiest to use control system on the market, and with QCM the IR Patrol offers full customization.

Performance, Durability and Affordability
Whether you are protecting our borders, searching for a lost child, or eradicating groups of feral hogs, operators need high resolution thermal images in a small robust device. The IR Patrol thermal monocular is a game changer for the night vision industry. For the first time ever, night vision users can enjoy thermal high definition imagery for under five thousand dollars ($5,000.00 USD).

The IR Patrol features an advanced user interface with a military grade thumb stick that is the perfect size - no more searching for buttons in the dark. With the monocular's ergonomic design, users can take advantage of all the functionality, including the menu system that is engineered to be intuitive and efficient to operate.

Quality, Quality and Quality
The IR Patrol was designed for military applications at a consumer affordable price point. All the components inside the IR Patrol are the highest quality. The BAE Systems long wave infrared (LWIR) uncooled, 60Hz thermal core, combined with Emagin's OLED, 10,000:1 contrast VGA display and our 6061 aircraft aluminum housings, are the highest quality system components available. All made in the USA.

The IR Patrol M250 Thermal Monocular steps up the performance to 60Hz fast frame rate delivering sharp, detailed imagery. The system also features the Wilcox Shoe Interface to allow helmet mounting for hands-free use. Even more, the M250 includes edge detection mode for tactical use.
