The GOYOJO 256×192 Thermal Imaging Monocular is a compact infrared observation device designed for wildlife observation, farm monitoring, property inspection, outdoor exploration, camping and general heat-source detection.

Equipped with a 256 × 192 thermal detector, 12 μm pixel pitch and 50 Hz refresh rate, the monocular provides smooth thermal imaging for observing heat signatures during both daylight and complete darkness.

Two objective-lens configurations are available: a 10mm fixed-focus lens with a wider 17.5° × 13.1° field of view, and a 15mm manual-focus lens with a narrower 11.7° × 8.8° field of view for more focused observation.

Selectable 1X, 2X and 4X digital zoom, six thermal image modes and built-in Wi-Fi connectivity provide additional flexibility for outdoor thermal observation.

256 × 192 Thermal Imaging

The GOYOJO thermal monocular uses a 256 × 192 thermal detector with a 12 μm pixel pitch.

The thermal detector senses infrared energy emitted by objects and converts differences in temperature into a visible thermal image.

Because thermal imaging detects infrared energy instead of relying on conventional visible illumination, the device can locate heat signatures during both daylight and darkness.

50 Hz Refresh Rate

The thermal imaging system operates at a listed 50 Hz refresh rate, providing smooth image updates during handheld observation.

The faster image presentation is particularly useful when scanning outdoor areas, following moving heat signatures and repositioning the monocular during observation.

10mm Fixed-Focus Version

The 10mm version combines the 256×192 thermal detector with a fixed-focus objective lens.

Lens: 10mm
Focus: Fixed
Field of View: Approximately 17.5° × 13.1°
Digital Zoom: 1X / 2X / 4X

Its wider field of view makes the 10mm configuration well suited to scanning larger surrounding areas, wildlife observation, farm monitoring and general thermal surveying.

The fixed-focus design also simplifies operation because manual adjustment of the objective focus is not required.

15mm Manual-Focus Version

The 15mm version provides a narrower viewing angle with manual focusing.

Lens: 15mm
Focus: Manual
Field of View: Approximately 11.7° × 8.8°
Digital Zoom: 1X / 2X / 4X

Compared with the 10mm version, the narrower field of view provides a larger apparent subject size at the same distance, making the 15mm configuration suitable for more focused observation.

Manual focus allows image clarity to be adjusted according to observation distance.

10mm vs 15mm Lens

The two lens options provide different viewing characteristics.

10mm Fixed Focus: Best suited to wider-area scanning and general observation. Its wider field of view makes it easier to locate heat signatures across a larger scene.

15mm Manual Focus: Better suited to more focused observation. Its narrower field of view provides greater apparent subject size while manual focusing allows image clarity to be adjusted for different distances.

For your website, I recommend offering these as two clear variants:

256×192 – 10mm Fixed Focus
256×192 – 15mm Manual Focus

1X / 2X / 4X Digital Zoom

Both 256×192 configurations support 1X, 2X and 4X digital zoom.

Digital zoom electronically enlarges the displayed thermal image for closer observation. It does not increase the native 256×192 detector resolution.

Six Thermal Image Modes

The monocular provides six thermal image modes, giving users multiple ways to display temperature differences within the observed scene.

Different thermal viewing modes can improve the visibility of heat signatures according to the environment and viewing preference.

Wi-Fi Connectivity

Built-in Wi-Fi connectivity provides wireless connectivity between the thermal monocular and compatible smart devices.

This adds connected functionality to the portable thermal observation system.

Suitable Applications

The GOYOJO 256×192 Thermal Imaging Monocular is suitable for:

• Wildlife observation
• Farm and livestock monitoring
• Property inspection
• Outdoor exploration
• Camping
• Search-support activities
• Building heat-loss checks
• Electrical inspection
• Machinery monitoring
• General heat-source detection

Safety & Care

Avoid pointing the thermal detector directly at the sun, welding arcs, lasers or other intense energy sources, as these can damage the sensor.

Keep the objective lens clean and dry and protect the device during storage and transportation.
