The Oselect - TS004 Thermal Imaging Monocular (OD Green) is a handheld optic designed for wildlife observation, perimeter security, and feral pest spotting through fog, mist, and heavy cover. Built around a 256 × 192 infrared sensor with a 50 Hz refresh rate, the monocular pairs a 13 mm focal length lens with a 720 × 540 LCOS display to detect thermal signatures at distances of up to 410 metres. An internal 5,000 mAh lithium battery provides up to 11 hours of continuous operation and recharges via standard 5V USB power sources. Encased in a protective silicone skin rated to IP67 dust and water resistance with 2-metre drop protection, the unit includes 32 GB of internal storage, integrated Wi-Fi streaming via the TopInfrared application, an onboard LED utility light, and AI-assisted recognition algorithms for people and vehicles.

Key Features

• 256 × 192 Thermal Core: Captures heat signatures with a 50 Hz refresh rate across an 8–14 µm spectral range for smooth target tracking.
• Optical and Digital Zoom: Features a 13 mm manual focus lens combined with 1x, 2x, 4x, and 8x digital magnification levels.
• Extended Battery Life: Built-in 5,000 mAh rechargeable battery delivers up to 11 hours of continuous field runtime on an approximate 4-hour USB charge.
• Ruggedised Housing: IP67-rated waterproof and dust-tight construction with impact resistance tested against drops from up to 2 metres.
• Internal Media & Connectivity: Stores video and still captures on 32 GB of internal memory and streams live footage over Wi-Fi via the TopInfrared mobile app.
• Multi-Palette Imaging: Includes White Hot, Black Hot, Red Hot, Bird, and Dual Fusion/Remix display modes alongside high/low temperature alarms.

Who is the Oselect - TS004 Thermal Imaging Monocular for?

• Close-range feral pest controllers — delivers positive target identification up to 91 metres through a 13 mm focal length lens and 256 × 192 sensor resolution, allowing shooters to confirm small game species in dense scrub before taking a shot.
• Rural property owners — utilizes a 410-metre maximum detection range and up to 11 hours of continuous runtime on a single charge to scan boundary fences, paddocks, and outbuildings for heat anomalies or intruders without requiring mid-shift recharging.
• Spotlighters transitioning to thermal scanning — provides an onboard 50 Hz refresh rate and a 410-metre detection window in a dedicated handheld thermal imaging monocular, eliminating the visible light beam that spooks resting game during nocturnal observation.

Less suitable for: Open-country hunting requiring positive target identification past 100 metres or shooters needing direct weapon mounting on a firearm; long-range field applications require a dedicated weapon-mounted thermal riflescope or a higher-resolution 384×288 or 640×512 thermal monocular with a 19 mm to 35 mm+ optical lens.
