Dali S240E Thermal Monocular

• 384x288 thermal sensor: The uncooled FPA sensor gives this thermal monocular enough detail to separate animals, people, and background heat sources more clearly than entry-level thermal viewers, which helps with faster target detection and more confident observation.
• Wide 29.00 ° field of view: A broad viewing angle and 500.00 m/1000m field of view make it easier to scan woodland edges, fields, and open ground without constantly sweeping the device, which is especially useful for short- to mid-range searching.
• 2.00x to 4.00x viewing range: The base 2.00 x magnification keeps the image easier to manage when scanning, while the higher 4.00 x setting lets the user inspect heat signatures more closely when something needs a second look.
• Photo and video recording: Built-in image capture, video recording, and video output let the monocular document sightings and observations, which is useful for reviewing activity later or sharing footage with others.
• Compact, field-ready housing: With a 190.00 mm body, 500.00 g weight, Li-ion power supply, up to 5.00 h battery life, and waterproof and fogproof construction, it is easier to carry and keep in service during long sessions in variable weather.

About the Dali Thermal Monoculars Series

Dali Thermal Monoculars sit in the brand’s outdoor thermal-imaging range as compact handheld viewers built for hunting, observation, and general outdoor use. The series focuses on practical field handling: a one-handed format, straightforward controls, and thermal detection that works in darkness, brush, and other situations where conventional optics depend on visible light. Across the range, DALI uses uncooled focal-plane-array detectors, a format widely used for portable thermal devices because it keeps the system compact while still delivering usable detection performance.

Within the broader family, DALI’s monocular lineup covers several configurations, including models aimed at simple scanning and others with more advanced viewing and connectivity functions. Depending on model, the series can include features such as digital zoom, photo and video recording, Wi-Fi image transmission, hotspot tracking, and picture-in-picture. That makes the line suitable for users who want anything from a basic thermal spotter to a more connected observation tool. The common theme is a portable thermal monocular that prioritizes fast deployment, practical image interpretation, and field usability over unnecessary bulk.

About the Dali S240E Thermal Monocular

The Dali S240E Thermal Monocular is a compact handheld thermal viewer designed for users who need a simple observation tool for short- to medium-range detection. Its 384x288 uncooled FPA sensor and 17.00 μm pixel pitch provide a balanced combination of image detail and practical portability, making the monocular suitable for spotting heat sources during night walks, property monitoring, wildlife observation, and similar field tasks. With a stated detection range of 750.00 m, it is built to reveal heat signatures well beyond normal visible-light limits.

The optical setup favors fast scanning. A 2.00 x base magnification gives a stable, easier-to-read view for searching nearby ground and wider areas, while the maximum 4.00 x magnification helps inspect a detected subject more closely. The 29.00 ° field of view is especially useful in tighter terrain or when tracking movement across a broad scene, because it shows more of the surroundings in a single glance. Since this model uses digital magnification rather than optical zoom, it is best suited to users who value quick area coverage first and closer inspection second.

In practical use, the S240E also benefits from features that support regular field carry. Automatic and manual calibration modes help maintain a stable thermal image under changing conditions. Photo capture, video recording, and video output add documentation capability for review or reporting. The LCD display, Li-ion power supply, and up to 5.00 h battery life keep the unit straightforward to operate, while the waterproof and fogproof housing supports use in damp, cold, or changeable weather.

About Dali

Dali traces its origins to the Zhejiang Provincial Testing Technology Research Institute, established in 1984. The company is based in Hangzhou, Zhejiang, China, and it developed from a research background into a manufacturer focused on infrared and optoelectronic systems. After restructuring in 2001, the business was listed on the Shenzhen Stock Exchange in February 2008, reflecting its growth into a larger technology company.

In the thermal-imaging field, Dali works across a broad product base that includes thermal monoculars, riflescopes, and binoculars, alongside infrared core components and complete thermal-imaging systems. Its expertise includes uncooled focal-plane-array detectors and infrared imaging cameras, which are directly relevant to handheld outdoor devices such as this monocular. The IRtech name is used as Dali’s professional thermal-imaging brand, linking the company’s detector and system experience to products intended for field observation and outdoor use.
