Dali S242 Thermal Monocular

• 240x180 thermal sensor: The uncooled FPA sensor gives this monocular true heat-based detection, helping users pick out animals, people, and other warm targets in darkness, brush, or poor weather where conventional optics lose contrast.
• 1x native view with up to 4x magnification: A true 1.00 x base magnification keeps scanning natural and easy at short to medium distances, while the extended magnification range helps with closer target assessment without carrying a larger device.
• 50 Hz refresh rate: Fast image refresh makes panning smoother and reduces lag when tracking moving subjects, which is especially useful for handheld observation during hunting or general outdoor use.
• LCOS display with photo and video recording: The 720x540 display presents the thermal image clearly for observation, while onboard image and video capture lets users document sightings, review activity, or share footage later.
• Compact, weather-resistant housing: At 400.00 g and 230.00 mm long, the Dali S242 remains easy to carry for extended sessions, and its waterproof and fogproof construction supports reliable use in damp, cold, or changeable field conditions.

About the Dali Thermal Monoculars Series

Dali Thermal Monoculars sit within the company’s outdoor thermal range and are built for users who need a compact handheld device for hunting, observation, and outdoor travel. Across the series, the emphasis is on practical field use rather than bulky form: small dimensions, one-handed handling, and core thermal functions that help users detect heat sources quickly in darkness or obscured terrain. In DALI’s lineup, these monoculars serve as portable observation tools for users who want thermal imaging without moving to a dedicated weapon sight.

The family is defined by uncooled focal-plane-array detectors and a feature set that commonly includes digital zoom, photo and video recording, Wi-Fi image transmission, hotspot tracking, and picture-in-picture. That combination makes the series suitable for both simple scanning and more deliberate target observation. The range also spans several sensor and display configurations, so different models balance image detail, field coverage, and price differently. Overall, the series is designed around straightforward controls, mobile use, and thermal imaging performance that supports real field observation rather than bench use.

About the Dali S242 Thermal Monocular

The Dali S242 Thermal Monocular is a compact handheld thermal viewer built around a 240x180 uncooled FPA sensor, making it well suited to short- and medium-range scanning where fast heat detection matters more than high optical magnification. Its 1.00 x native magnification gives a natural viewing perspective that is easier to use when sweeping fields, woodland edges, farm buildings, or tracks, and the extended magnification up to 4.00 x provides extra image enlargement when a user needs to inspect a heat source more closely.

The combination of a 15.00 mm objective lens and a wide 15.60 ° field of view favors coverage and situational awareness. In practice, that makes the S242 useful for locating movement quickly instead of searching through a narrow image window. Its 50.00 Hz refresh rate also helps the image remain smoother during handheld panning, which is important when following moving animals or scanning from a vehicle stop or hide.

The thermal image is viewed on a 720x540 LCOS display, and the monocular supports image capture, video recording, and video output, adding value for users who want to document observations or review what they saw later. Automatic and manual calibration modes allow the image to be managed according to conditions, while the waterproof and fogproof housing supports dependable use in rain, cold mornings, and shifting temperatures. With a weight of 400.00 g, the S242 remains easy to carry as a dedicated spotting tool in a hunting optics or outdoor kit.

About Dali

DALI traces its origins to the Zhejiang Provincial Testing Technology Research Institute, established in 1984. The company was restructured in 2001 and was listed on the Shenzhen Stock Exchange in February 2008. Based in Hangzhou, Zhejiang, China, DALI focuses on infrared and optoelectronic technologies rather than general sporting optics.

Its expertise includes uncooled focal-plane-array detectors, infrared thermal-imaging cameras and systems, optoelectronic inertial-navigation products, and more complex optoelectronic systems. That background is directly relevant to handheld thermal devices such as the S242, because the company develops both core infrared components and complete thermal-imaging products. IRtech is presented as a professional thermal-imaging brand originating from DALI, and the company’s outdoor range includes thermal monoculars, riflescopes, and binoculars.
