Thermal monocular DALI S236P — 640×512 resolution, 35 mm lens

The DALI S236P thermal monocular features a 640×512 uncooled VOx detector with a 35 mm lens and a 12.5° × 10° field of view, designed for handheld single-eye thermal observation. It delivers a 1280×960 color LCOS display, built-in 32 GB memory (expandable via supported external storage), Wi‑Fi streaming, and a laser rangefinder (LRF) with ±1 m accuracy up to 1000 m. The device offers more than 6 hours of continuous operation on its rechargeable Li‑ion battery and has IP66 dust- and water-resistance for outdoor use.

Advantages

The thermal sensor with 640×512 resolution and NETD <40 mK at 30°C provides detailed temperature contrast and clear target detection in low-light or no-light conditions. The integrated LRF and digital compass support accurate distance and directional information while Picture-in-Picture (PIP) and 4× digital zoom allow closer views without losing overall context. Built-in Wi‑Fi enables live streaming to smart devices, and USB Type‑C supports fast data transfer, external charging and connection to power banks. Multiple color palettes and hot-spot detection simplify target identification.

Suitable for

• Wildlife observation and nature monitoring
• Search and rescue tasks in low-visibility conditions
• Security patrols and property surveillance
• Inspection and maintenance of infrastructure
• Outdoor navigation and night observation

How to use

Power on the DALI S236P and allow the detector to stabilize. Use the diopter knob to focus the eyepiece, select a color palette and adjust digital zoom or PIP to refine the view. Press the LRF button to measure distance; the device displays distance readings and can continuously update them. Use the built-in photo and video functions to record observations to internal memory or stream via Wi‑Fi to a compatible smartphone or tablet using the manufacturer app. Recharge the internal battery through the USB Type‑C port or connect an external power bank for extended operation.

Usage recommendations

For best detection performance, operate the monocular after a short warm-up period, keep the lens clean and avoid pointing directly at strong heat sources. Use the appropriate color palette and PIP when identifying small or distant targets, and carry a charged external battery for extended field sessions.
