    Thermal Sensor Options

    The GOYOJO thermal viewer is available with three detector resolutions.

    256 × 192 Sensor

    The 256 × 192 configuration may be suitable for basic observation and general heat-source detection where compact size and lower cost are priorities.

    384 × 288 Sensor

    The 384 × 288 version offers a higher native pixel count and may provide improved image detail and subject separation.

    640 × 512 Sensor

    The 640 × 512 configuration provides the highest listed native resolution and may support:

    • Greater visible thermal detail

    • Better subject separation

    • Improved image quality during digital zoom

    • Clearer observation of smaller heat sources

    • More detailed long-distance viewing

    Each sensor version should have a separate SKU, specification sheet, product image, and price.

    Objective Lens Options

    Available objective-lens focal lengths include:

    • 25 mm

    • 35 mm

    • 50 mm

    25 mm Lens

    A 25 mm lens generally provides a wider field of view and may be more suitable for closer-range scanning and broad-area observation.

    35 mm Lens

    A 35 mm lens provides a balance between field of view, apparent magnification, and observation distance.

    50 mm Lens

    A 50 mm lens generally provides a narrower field of view and larger apparent subject size for longer-distance observation.

    Exact performance depends on the selected sensor resolution and lens aperture.

    Field of View

    Field-of-view information has not been supplied.

    Before publishing, provide separate values for every available combination, including:

    • 256 × 192 with 25 mm lens

    • 256 × 192 with 35 mm lens

    • 256 × 192 with 50 mm lens

    • 384 × 288 with 25 mm lens

    • 384 × 288 with 35 mm lens

    • 384 × 288 with 50 mm lens

    • 640 × 512 with 25 mm lens

    • 640 × 512 with 35 mm lens

    • 640 × 512 with 50 mm lens

    Field of view should be stated in degrees and, where available, metres at 100 metres.

    50 Hz Refresh Rate

    The listed 50 Hz frame rate supports smooth thermal-image presentation during:

    • Handheld scanning

    • Subject tracking

    • Walking observation

    • Vehicle inspection

    • Machinery inspection

    • Outdoor monitoring

    Final image smoothness also depends on the processor, display, and image-enhancement system.

    Internal Display

    The thermal device includes a listed display resolution of 1024 × 768 pixels.

    Before publication, confirm:

    • OLED or AMOLED technology

    • Screen size

    • Display brightness settings

    • Diopter-adjustment range

    • Eye relief

    • Contrast adjustment

    • Image sharpening

    • Noise reduction

    • Colour-palette support

    The display resolution should not be confused with the thermal detector resolution.

    Digital Magnification

    The device supports stepped electronic magnification at:

    • 1x

    • 2x

    • 4x

    • 8x

    Digital zoom enlarges the displayed image but does not increase the thermal detector’s native resolution. Image detail may decrease at higher magnification settings.

    The final listing should also include the base optical magnification for each lens configuration.

    Photo and Video Recording

    The device supports photo and video recording.

    Before publishing, confirm:

    • Photo resolution

    • Video resolution

    • Video frame rate

    • File formats

    • Internal storage capacity

    • Available recording duration

    • Memory-card compatibility

    • Audio recording

    • USB file transfer

    • Date and time stamping

    RAW Thermal Data

    The supplied specification mentions “RAV” recording, which may be a typographical error for RAW thermal data recording.

    Confirm whether the device records:

    • Standard images only

    • Standard video only

    • Radiometric thermal data

    • Raw sensor data

    • Temperature-measurement information

    Do not advertise radiometric recording unless the device stores measurable temperature data for later analysis.

    IP66 Environmental Protection

    The listed IP66 rating indicates that the verified enclosure may provide:

    • Complete protection against dust ingress

    • Resistance to powerful water jets

    Before publication, confirm:

    • Valid IP test report

    • Exact covered model

    • Required charging-port covers

    • Battery-compartment sealing

    • Water-exposure limitations

    • Warranty conditions

    IP66 does not mean the device is designed for immersion underwater.

    Battery Life

    The thermal viewer provides a listed operating duration of up to approximately eight hours.

    Actual battery life may vary according to:

    • Display brightness

    • Video recording

    • Wi-Fi usage

    • Ambient temperature

    • Digital zoom

    • Battery age

    • Image-processing mode

    Before publication, confirm the battery chemistry, capacity, charging time, and whether it is replaceable.

    Thermal Sensitivity

    The supplied information does not include a NETD value.

    NETD is an important specification because it indicates how effectively the device can distinguish small temperature differences.

    Confirm:

    • NETD value

    • Test temperature

    • Lens used during testing

    • Image-processing mode

    • Sensor refresh rate during testing

    Detection and Recognition Distance

    Detection-distance information is missing.

    For each sensor and lens configuration, confirm:

    • Human-sized target detection range

    • Human-sized target recognition range

    • Vehicle detection range

    • Vehicle recognition range

    • Test conditions

    • Target dimensions

    Detection means noticing a heat source and should not be described as positive identification.

    Thermal Colour Palettes

    Confirm whether the device includes image modes such as:

    • White Hot

    • Black Hot

    • Red Hot

    • Iron Red

    • Rainbow

    • Target Highlight

    • Edge Enhancement

    Only verified firmware features should appear in the final listing.

    Suitable Applications

    Depending on the selected configuration, the thermal monocular may be suitable for:

    • Wildlife observation

    • Farm monitoring

    • Property inspection

    • Search support

    • Night-time outdoor observation

    • Building heat-loss inspection

    • Electrical inspection

    • Machinery maintenance

    • Security patrols

    • General heat-source detection

    Performance depends on target size, temperature contrast, weather, lens selection, and sensor resolution.
