384 × 288 VOx Thermal Detector

The TS-335LRF uses a 384 × 288 uncooled vanadium oxide thermal detector with a 12 μm pixel pitch.

This configuration may provide:

• Detailed heat-signature presentation
• Smooth outdoor thermal observation
• Better image quality during digital enlargement
• Separation of nearby warm objects
• Day and night operation
• Compact and energy-efficient construction

Actual image quality depends on thermal sensitivity, lens quality, target size, atmospheric conditions, temperature contrast, focusing, and image-processing settings.

Missing Thermal Sensitivity

The NETD value is not supplied.

Before publication, confirm:

• NETD in millikelvin
• Test temperature
• Lens aperture used during testing
• Image-processing mode
• Detector calibration standard

NETD is an important indicator of the camera’s ability to distinguish small temperature differences.

35 mm F1.0 Objective Lens

The device includes a 35 mm thermal objective lens with an F1.0 aperture.

This lens configuration may offer a balance between:

• Medium- and long-distance thermal observation
• Subject detail
• Field of view
• Image brightness
• Portable device size

Before publication, confirm:

• Germanium lens material
• Manual or fixed focus
• Minimum focusing distance
• Field of view
• Protective coating
• Lens-cap inclusion

Detection-Distance Clarification

The listing includes several different distance claims:

• Effective visual distance: approximately 1,000 m
• Human detection distance: approximately 1,450 m
• Vehicle detection distance: approximately 3,400 m
• Laser rangefinder distance: 1,000–1,500 m

These figures describe different functions and should not be combined.

Thermal Detection

Detection means that a heat source may be visible against the background.

Recognition

Recognition means the user may determine the general category of the observed object.

Identification

Identification requires sufficient image detail to determine exactly what the object is.

Before publishing the distances, confirm:

• Target dimensions
• Target temperature difference
• Weather conditions
• Detection criteria
• Recognition criteria
• Lens focus
• Test methodology

Integrated Laser Rangefinder

The TS-335LRF includes a built-in laser rangefinder.

Two different maximum range claims are provided:

• 1,000 m
• 1,500 m

Before publication, confirm:

• Maximum range for reflective targets
• Maximum range for non-reflective targets
• Minimum measuring distance
• Measurement accuracy
• Laser wavelength
• Laser classification
• Single-ranging mode
• Continuous-ranging mode
• Measurement units
• Range refresh rate

The rangefinder distance must remain separate from thermal detection distance.

Digital Zoom

The device supports the following listed digital enlargement levels:

• 1x
• 2x
• 4x

A separate marketplace field lists magnification as 2–4x.

Before publication, clarify whether the device has:

• Fixed base optical magnification
• 1x native display view
• 2x and 4x digital enlargement
• Continuous digital zoom

Digital zoom enlarges the displayed pixels and does not increase the detector’s native resolution.

OLED Display

The thermal monocular includes a 0.39-inch OLED display.

OLED technology may provide:

• High image contrast
• Deep black levels
• Clear palette presentation
• Efficient power use
• Smooth viewing in darkness

Before publication, confirm:

• Display resolution
• Physical panel dimensions
• Brightness levels
• Contrast settings
• Diopter range
• Eye relief
• Screen refresh rate
• Automatic sleep function

Display resolution should not be confused with the 384 × 288 thermal detector resolution.

Thermal Colour Palettes

The top specifications list:

• Black Hot
• White Hot
• Pseudocolour

The detailed description also mentions:

• Red Hot
• Iron Red

Confirm the exact available palette list for the production firmware.

Different palettes can help users interpret heat patterns in different environments.

Picture-in-Picture Mode

Picture-in-picture mode displays an enlarged portion of the thermal scene while preserving the wider image.

This may help with:

• Detailed observation
• Maintaining scene awareness
• Examining smaller heat sources
• Using digital zoom more effectively

Confirm:

• PIP magnification level
• Window position
• Window size
• Whether PIP appears in recordings

Hotspot Tracking

Hotspot tracking may automatically mark the warmest visible part of the scene.

This may be useful for:

• Equipment inspection
• Electrical checks
• Property monitoring
• Heat-source location
• General thermal analysis

It should not be described as automatic object identification.

Wi-Fi Connectivity

The TS-335LRF supports listed Wi-Fi transmission.

Potential mobile-app functions may include:

• Live thermal viewing
• Photo transfer
• Video transfer
• Remote recording
• Device settings
• Firmware updates

Before publication, confirm:

• Official application name
• Android compatibility

Before publication, confirm:

• Photo resolution
• Video resolution
• Recording frame rate
• Audio source
• File formats
• Storage capacity
• Maximum recording length
• Date and time stamping
• Playback support
• USB file transfer

Do not advertise audio recording unless the device includes a microphone and the function is enabled in the final firmware.

Internal Storage

The internal storage capacity is not supplied.

Before publication, confirm:

• Total memory
• Available user space
• Photo capacity
• Video recording duration
• File overwrite behaviour
• Storage formatting

• Charging duration
• Charging connector
• Power-bank operation
• Replaceable battery availability
• Low-temperature runtime

Actual battery life may vary according to Wi-Fi, recording, display brightness, rangefinder use, digital zoom, and ambient temperature.

Operating Voltage

The listed operating voltage is 5 V.

Confirm whether this refers to:

• USB charging input
• External operating power
• Battery charging voltage
• Internal system voltage

The final listing should specify the required charging current and adapter rating.

IP66 Environmental Protection

The listed IP66 rating may provide:

• Dust-tight enclosure protection
• Resistance to strong water jets under controlled conditions

Before publication, verify:

• Exact tested model
• Port-cover requirements
• Battery-compartment sealing
• Test laboratory
• Exposure limitations
• Warranty coverage

IP66 does not mean the device is suitable for underwater use.
