RIX Stride ST3 Lite Thermal Monocular
Thermal Monocular
Core Features
The Stride ST3 Lite is a 0.42 lb, 1x thermal monocular made to be carried for hours or worn on a helmet. Its 384x288 sensor with thermal sensitivity under 20 mK sits behind a 15 mm F1.0 lens for a wide 17.5 x 13.1 degree field of view, true 1x base magnification that keeps your natural sense of the surroundings, 1-6x digital zoom and an 852 yard detection range. A 1024x768 OLED display, six color palettes, 32 GB of recording, Wi-Fi to the RIX+ app and a replaceable 18650 battery are built in. Two helmet adapter kits ship in the box. IP67 rated with a 5 year warranty.
Wide Field, True 1x
At 1x the ST3 Lite shows the world at its natural scale, so you can walk, scan and move with it to your eye. The 17.5 degree horizontal field covers more ground per sweep than a magnified scanner, and 1-6x digital zoom is there when you need a closer look.
384 Sensor and OLED Display
The 12 micron 384x288 sensor at 50 Hz with sensitivity under 20 mK keeps the image sharp in fog and humidity. Six selectable palettes, including eye-care options for long sessions, show on a 1024x768 OLED display with -5 to +5 diopter adjustment.
Helmet, Vehicle or Hand
Two adapter kits are included so the ST3 Lite can go on a helmet mount without extra parts, and built-in screw mounts suit vehicle and tripod use. The optional BM-01 bridge mount is available separately.
Recording and RIX+ App
32 GB of built-in storage captures photo and video at 1024x768 with sound from the built-in microphone. Built-in Wi-Fi connects to the RIX+ app on iOS and Android for live streaming, file transfer and firmware updates.
Power
A swappable 18650 battery (70 mm length) runs about 4 hours at 72 F, and the USB-C port accepts 5V external power. Battery, charger and fireproof bag are included.
Durability
IP67 waterproof and dustproof, rated for -4 F to 122 F, with a 5 year warranty.
