Dali S246L Thermal Monocular

• 384x288 thermal sensor: The uncooled FPA sensor gives the Dali S246L Thermal Monocular enough detail for confident target detection and terrain reading, while the 17.00 μm pixel pitch supports a practical balance between image definition and scanning coverage.
• 1600.00 m detection range: Long detection capability helps pick up heat sources well before they enter close range, which is useful for field observation, wildlife spotting, and general night-time area surveillance.
• 50.00 Hz refresh rate: A faster refresh rate keeps motion looking smoother when panning or tracking moving subjects, making the image easier to interpret during handheld use.
• WiFi, photo and video recording: Built-in connectivity and onboard capture functions make it easier to document observations, review footage later, or share the live view with a mobile device in the field.
• Compact 500.00 g handheld design: With its slim 230.00 mm body, tripod adaptability, and 4.00 h Li-ion power system, this thermal monocular remains manageable for extended scanning sessions without adding unnecessary bulk.

About the Dali Thermal Monoculars Series

Dali Thermal Monoculars sit within the brand’s outdoor thermal-imaging range and are built for users who need a compact handheld device for hunting, observation, and outdoor journeys. The series centers on the practical strengths of a thermal monocular: quick deployment, one-handed use, and the ability to detect heat signatures in darkness, brush, or visually cluttered terrain where conventional optics are limited. Across the range, DALI focuses on features that support field use rather than bench use, including uncooled focal-plane-array detectors, digital zoom, WiFi image transmission, and onboard photo and video recording.

Within the broader family, DALI’s monocular lineup covers several formats and performance levels, giving users a choice between more compact entry-oriented models and more capable units intended for longer detection distances or more detailed thermal observation. The series is defined by straightforward controls, mobile-app connectivity, and viewing modes such as picture-in-picture and hotspot tracking on applicable models. In practical terms, the Dali Thermal Monoculars series is aimed at users who want thermal imaging in a portable format that is easy to carry, fast to operate, and suited to scanning large areas without the weight or mounting requirements of a dedicated thermal scope.

About the Dali S246L Thermal Monocular

The Dali S246L Thermal Monocular is a handheld thermal device built around a 384x288 uncooled FPA sensor, a 35.00 mm objective lens, and a 1600.00 m detection range. This combination gives it a useful role as a general-purpose thermal monocular for scanning open ground, checking woodland edges, and locating heat sources at distances where a standard daylight optic is no longer effective. Its 2.00 x base magnification provides an immediately usable image for searching, while the 4.00 x maximum magnification adds extra reach when a closer look is needed without turning the unit into a narrow, difficult-to-hold viewer.

The sensor’s 17.00 μm pixel pitch and 80.00 mK NETD place the emphasis on dependable detection and recognition in ordinary field conditions, while the 50.00 Hz refresh rate helps maintain a smoother image when sweeping across terrain or following moving animals. The 15.70 ° field of view supports efficient area scanning, which matters when the monocular is used as a spotter before switching to another optic or when checking multiple sectors quickly.

The LCD display with 640x480 resolution presents the thermal image in a clear, familiar format, and the monocular adds practical field functions through WiFi connectivity, image capture, video recording, and video output. Its 500.00 g body remains light enough for prolonged handheld use, while tripod adaptability gives the option of steadier observation from a fixed position. Waterproof and fogproof construction, together with an operating range of - 20°C / + 50°C, make the S246L suitable for regular outdoor use across changing weather and temperatures.

About Dali

DALI traces its origins to the Zhejiang Provincial Testing Technology Research Institute, established in 1984. Based in Hangzhou, Zhejiang, China, the company developed specialist expertise in uncooled focal-plane-array detectors and infrared thermal-imaging cameras and systems, which makes it directly relevant to handheld thermal devices such as the S246L. The business was restructured in 2001 and listed on the Shenzhen Stock Exchange in February 2008, reflecting its growth from a research-rooted organization into a broader optoelectronics manufacturer.

In the thermal-imaging field, DALI is associated with IRtech, a professional thermal-imaging brand that identifies itself as originating from DALI. Its product scope includes outdoor thermal monoculars, riflescopes, and binoculars, alongside infrared core components, thermal-imaging systems, optoelectronic inertial-navigation products, and other complex optoelectronic systems. That background shows in products designed around in-house thermal expertise rather than simple consumer-electronics packaging.
