ATN OTS 4T 384 7-28x

• 384x288 thermal sensor: The 384x288 sensor gives this monocular the resolution needed to separate animals, people, and background heat sources clearly enough for observation, scanning, and target confirmation at longer distances.
• 7-28x magnification range: This high base magnification favors long-distance detection and detailed observation, while the extended digital zoom range helps inspect heat signatures more closely without carrying a larger device.
• 3000 m detection range: A long stated detection range makes the OTS 4T suitable for open-country use, search tasks, and surveillance where early heat-signature pickup matters more than close-range field of view.
• 18-hour Li-ion battery life: Long runtime reduces the need for spare power management during night hunts, patrol work, or extended observation sessions in the field.
• WiFi and onboard video recording: Wireless connectivity and internal recording make it easier to save observations, review footage later, or share the live view with a phone or tablet during team use.

About the ATN OTS 4T Series

The ATN OTS 4T series is a family of handheld thermal monoculars in ATN’s Obsidian 4T line, built for users who need a compact observation device rather than a weapon-mounted optic. The series is intended for spotting, hunting, stalking, game recovery, and search-and-rescue, so the emphasis is on fast thermal detection, practical field features, and straightforward handheld use. Across the range, ATN pairs its Obsidian IV Dual Core T processor with Smart HD functions that go beyond simple image viewing.

Depending on the model, the series is available with 384 × 288 or 640 × 480 Gen 4 thermal sensors and different magnification ranges, letting users choose between wider-area scanning or more reach for distant observation. Shared functions such as Wi-Fi video streaming, onboard recording, an electronic compass, and a Smart Range Finder make the OTS 4T series useful not only for finding heat signatures, but also for documenting sightings and maintaining orientation in the field. The result is a thermal monocular family designed for users who want digital functionality and long observation capability in a dedicated handheld format.

About the ATN OTS 4T 384 7-28x

The ATN OTS 4T 384 7-28x is the long-range oriented version of the OTS 4T family. Its 7x base magnification is notably higher than that of general-purpose thermal monoculars, which makes it especially suitable for users who spend more time observing distant terrain, field edges, open ground, or long approach routes than scanning tight woodland or short-range spaces. Combined with a stated 28x maximum magnification, it gives the user more image scale for checking whether a heat source is worth approaching or monitoring further.

The thermal core uses a 384x288 sensor with a 60 Hz refresh rate, helping moving animals or people appear more natural during panning and tracking. A stated 3000 m detection range supports early spotting at distance, while the Micro-HD display with 1280x960 resolution provides a detailed viewing image for extended observation. Video recording at 1280x960 adds practical value for documenting sightings, reviewing movement patterns, or sharing footage after the session.

In the field, the OTS 4T 384 7-28x also benefits from its 18-hour battery life, which is useful for overnight use without frequent charging breaks. WiFi connectivity adds live-streaming and device-linking capability, while the waterproof and fogproof construction supports use in damp or changeable weather. At 900 g and 260.00 mm long, it is a substantial handheld thermal monocular, but that size supports the role of a dedicated long-range observation tool rather than a pocket carry device.

About ATN

ATN was founded in 1995 in Silicon Valley, California, and the company is now headquartered in Doral, Florida. ATN focuses on night-vision, thermal-imaging, and digital day-and-night optics, with product lines that cover traditional image-intensifier systems as well as digital and thermal devices. This specialization has made the brand particularly visible in hunting and observation optics where electronic imaging, onboard recording, and app-connected features matter as much as the optical housing itself.

A key part of ATN’s recent product development has been its Obsidian 4 Dual Core platform, introduced in 2018, which brought Smart HD functions to many of the company’s thermal and digital optics. ATN is also known for its 4K digital day-and-night systems and for expanding thermal imaging into a broad catalog of handhelds, scopes, and binocular-style devices. In this category, the company’s reputation rests on combining thermal detection with practical digital tools rather than treating thermal imaging as a stand-alone viewing function.
