384 × 288 Thermal Detector

The HT-C8 uses a listed thermal resolution of 384 × 288 pixels.

This detector configuration may support:

  • Detailed thermal-image presentation
  • Better separation between nearby heat sources
  • More usable detail during digital enlargement
  • Outdoor observation without visible light
  • Property and equipment monitoring
  • Search and inspection applications

Actual image quality depends on detector material, pixel pitch, thermal sensitivity, lens quality, weather, humidity, target size, and temperature contrast.

Detector Information

The supplied information does not identify the detector material or pixel pitch.

Before publication, confirm:

  • VOx or amorphous-silicon detector
  • Cooled or uncooled construction
  • Pixel pitch
  • Spectral response
  • Detector manufacturer
  • Calibration method
  • Defective-pixel correction

Do not assume the detector type without manufacturer documentation.

Thermal Sensitivity

The listed NETD value is 40 mK or lower.

A lower NETD value generally indicates improved ability to distinguish small temperature differences.

This may support clearer imaging in:

  • High humidity
  • Fog
  • Light rain
  • Low-contrast environments
  • Uniform thermal backgrounds
  • Changing outdoor temperatures

Before publication, verify the test temperature, lens configuration, image-processing mode, and laboratory method.

25 mm Infrared Lens

The HT-C8 uses a listed 25 mm infrared objective lens.

This lens configuration may provide a balance between:

  • Field of view
  • Base magnification
  • Medium-distance observation
  • Subject visibility
  • Compact product dimensions

Before publication, confirm:

  • F-number
  • Germanium lens material
  • Fixed or manual focus
  • Minimum focusing distance
  • Field of view
  • Protective lens coating

Magnification and Digital Zoom

The listed zoom levels are:

  • 2x
  • 4x
  • 6x
  • 8x

These values likely refer to digital image enlargement rather than optical zoom.

Before publication, confirm:

  • Base optical magnification
  • Whether 1x viewing is supported
  • Continuous or stepped zoom
  • Zoom control method
  • Picture-in-picture zoom level

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

50 Hz Refresh Rate

The 50 Hz refresh rate supports smoother thermal image presentation during:

  • Handheld scanning
  • Walking observation
  • Monitoring moving heat sources
  • Property inspection
  • Outdoor exploration
  • Search activities

The final image smoothness also depends on display refresh rate and internal processing.

OLED Display

The HT-C8 uses a listed OLED display.

OLED technology may provide:

  • High image contrast
  • Deep black levels
  • Clear thermal palette presentation
  • Reduced motion blur
  • Efficient power use

Before publication, confirm:

  • Physical screen size
  • Display resolution
  • Brightness settings
  • Contrast adjustment
  • Diopter range
  • Eye relief
  • Screen refresh rate
  • Automatic timeout

Display resolution should be listed separately from the 384 × 288 thermal detector resolution.

Picture-in-Picture Mode

Picture-in-picture viewing displays an enlarged section of the thermal image while retaining the wider scene.

This may support:

  • Detailed subject observation
  • Maintaining surrounding scene awareness
  • Examining smaller thermal features
  • Better use of digital zoom

Confirm:

  • PIP magnification
  • Window size
  • Screen position
  • Whether PIP appears in recordings
  • Available palette combinations

Thermal Colour Palettes

The product description states that users can adjust thermal palettes, but the exact modes are not listed.

Confirm whether the HT-C8 includes:

  • White Hot
  • Black Hot
  • Red Hot
  • Iron Red
  • Rainbow
  • Fusion
  • Target Highlight

Only verified firmware modes should appear on the final product page.

Photo and Video Recording

The HT-C8 supports onboard photo and video recording.

Before publication, confirm:

  • Photo resolution
  • Video resolution
  • Recording frame rate
  • File formats
  • Audio recording
  • Maximum clip duration
  • Date and time stamping
  • Playback on the device
  • USB file transfer

Internal Storage

Internal memory is listed as supported, but the storage capacity is missing.

Before publication, confirm:

  • Total storage capacity
  • Available user storage
  • Estimated photo capacity
  • Estimated recording duration
  • File overwrite behaviour
  • Storage formatting procedure
  • Memory-card support

GPS Functionality

GPS is mentioned in the product description.

Before publishing this feature, confirm whether the device includes:

  • Built-in GPS receiver
  • Coordinates displayed on screen
  • Location stored with photos
  • Location stored with videos
  • Compass or orientation data
  • External smartphone-based GPS

Do not advertise GPS if the feature depends on an optional accessory or mobile application.

Battery-System Conflict

The listing states that no battery is included, but the product appears to be an electronic handheld thermal device.

Before publication, confirm:

  • Built-in or removable battery
  • Battery chemistry
  • Battery capacity
  • Number of batteries required
  • Whether batteries are included
  • Operating time per charge
  • Charging method
  • Spare-battery compatibility

The final product page should not show “battery not included” unless the device is genuinely sold without required batteries.

Environmental Protection

No waterproof or dustproof rating is provided.

Before promoting the HT-C8 for outdoor use, confirm:

  • IP protection rating
  • Operating-temperature range
  • Storage-temperature range
  • Humidity tolerance
  • Drop resistance
  • Vibration resistance
  • Port sealing
  • Condensation protection

Do not describe the product as waterproof without a verified IP rating.

Detection Range

No detection, recognition, or identification ranges are supplied.

Before publication, confirm:

  • Human-sized target detection range
  • Human-sized target recognition range
  • Vehicle detection range
  • Vehicle recognition range
  • Target dimensions
  • Temperature difference
  • Weather conditions
  • Test methodology

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

Suitable Applications

The HTI HT-C8 may be suitable for:

  • Wildlife observation
  • Farm monitoring
  • Property inspection
  • Outdoor exploration
  • Search and rescue support
  • Night-time observation
  • Building heat-loss checks
  • Electrical inspection
  • Machinery monitoring
  • General heat-source detection

Actual performance depends on detector quality, thermal contrast, weather, target size, distance, focus, and device settings.

Customization Options

OEM, ODM, and OBM services may include:

  • Custom branding
  • Housing colour
  • Packaging
  • Firmware
  • Menu language
  • Storage capacity
  • Accessories
  • User-interface settings

  • Rechargeable battery
  • Battery charger
  • USB cable
  • Protective lens cap
  • Eye cup
  • Wrist or neck strap

  • GPS module
  • Charging port
  • Buttons and controls
  • Environmental sealing
  • Labour and return shipping

Important Use Information

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

Keep the objective lens clean and dry, protect the device during transport, and use only compatible batteries, chargers, and accessories.

Follow all applicable privacy, observation, and local-use regulations.
