ATN OTS 4T 384 4.5-18x

• 384x288 thermal sensor: The 384x288 sensor gives this handheld thermal monocular enough detail for reliable spotting and target discrimination while keeping the image processing fast and responsive in the field.
• 4.5-18x viewing range: The 4.5x base magnification helps with positive identification at distance, while the extended digital zoom range lets the user inspect heat signatures more closely without carrying a larger observation device.
• 60 Hz refresh rate: A 60 Hz refresh rate keeps motion looking smoother when scanning moving animals, tracking across uneven ground, or panning quickly during search work.
• 18-hour Li-ion battery life: Long battery endurance reduces the need for spare power solutions and makes the monocular more practical for extended hunts, night observation, and long shifts outdoors.
• WiFi streaming and onboard recording: Built-in connectivity and video capture make it easier to document sightings, review observations later, or share the live view with a paired mobile device.

About the ATN OTS 4T Series

ATN OTS 4T is a family of handheld Smart HD thermal monoculars built within ATN’s Obsidian 4T line. The series is designed for users who need a compact thermal imaging tool for spotting, hunting, stalking, game recovery, and search-and-rescue work. Rather than functioning as a weapon sight, the OTS 4T platform is made for observation first, giving the user a dedicated handheld device for scanning terrain, checking treelines, and locating heat sources before moving in closer.

Across the series, ATN offers 384 × 288 and 640 × 480 Gen 4 thermal sensor options with different magnification ranges to suit shorter- and longer-distance observation. Shared core features include Wi-Fi video streaming, onboard video recording, an electronic compass, and a Smart Range Finder, all supported by ATN’s Obsidian IV Dual Core T processor. Every OTS 4T model also uses a 1280 × 720 HD microdisplay, which gives the user a clear viewing interface for scanning, tracking, and recording thermal scenes in varied field conditions.

About the ATN OTS 4T 384 4.5-18x

ATN OTS 4T 384 4.5-18x is the longer-range member of the 384-sensor branch of the series, built for users who need more reach from a handheld thermal monocular. Its 4.5-18x magnification range favors observation at distance, making it well suited to open-country scanning, checking field edges, and identifying heat sources before closing the gap. With a stated detection range of 1800.00 m, it is configured for finding thermal signatures far beyond normal visual range, which is especially useful in darkness, haze, or broken cover.

The thermal system combines a 384x288 sensor with 60.00 Hz refresh rate and 60.00 mK NETD. In practice, that means smoother viewing when panning and enough thermal sensitivity to separate heat signatures from the background in changing outdoor conditions. The 1280x720 Micro - HD display gives the image a clear presentation inside the eyepiece, while video recording at 1280x960 and video output support both evidence capture and post-use review.

This model is also shaped around practical field use. WiFi connectivity allows streaming and device integration, while the 18.00 h Li-ion battery life supports long sessions without frequent charging breaks. At 235.00 mm in length and 875.00 g in weight, it remains manageable as a handheld observation tool. Waterproof and fogproof construction adds confidence when moving between cold air, damp vegetation, and changing weather during night hunting or thermal surveillance work.

About ATN

ATN was founded in 1995 in Silicon Valley, California, and is a United States company now headquartered in Doral, Florida. The company focuses on night vision, thermal imaging, and digital day-and-night optics, with a product range that spans traditional image-intensifier systems as well as digital and thermal devices.

ATN is particularly known for bringing digital features into field optics. It introduced the X-Sight II HD digital day-and-night sight series in 2015, and in 2018 it launched products built around its Obsidian 4 Dual Core platform. That background is directly relevant to the OTS 4T, which belongs to ATN’s Smart HD thermal category and reflects the company’s emphasis on integrating imaging, recording, wireless connectivity, and onboard processing into practical hunting and observation optics.
