ATN OTS 4T 384 1.25-5x

• 384x288 thermal sensor: This resolution gives the monocular enough detail for reliable heat-source detection while keeping the image clean and easy to interpret during scanning, stalking, and recovery work.
• 1.25-5x magnification range: The low base magnification supports wide-area observation, while the higher setting helps inspect animals, terrain features, or points of interest without changing devices.
• Obsidian IV Dual Core T platform: ATN’s Smart HD processing supports smooth operation, onboard recording, wireless connectivity, and field tools that make the monocular more useful than a simple viewer.
• 1280x960 video recording and Wi-Fi: Recording and wireless sharing make it easier to document sightings, review observations later, or stream the view to a second device in the field.
• 18-hour battery life: Long runtime reduces the need to manage spare power during extended hunts, patrols, or search sessions, especially in cold and low-light conditions where thermal devices are often used longest.

About the ATN OTS 4T Series

The ATN OTS 4T series is a family of handheld thermal monoculars built around ATN’s Obsidian IV Dual Core T processing system and intended for users who need a compact observation tool rather than a weapon-mounted optic. Within ATN’s thermal lineup, the series sits as a Smart HD thermal monocular range for spotting, hunting, stalking, game recovery, and search-and-rescue work. The design focuses on combining thermal detection with digital functions that are genuinely useful in the field, including Wi-Fi video streaming, onboard recording, an electronic compass, and ATN’s Smart Range Finder.

The series is offered in 384x288 and 640x480 sensor variants, with different magnification ranges to suit either wider-area scanning or more detailed long-range observation. Across the range, the OTS 4T concept is straightforward: give the user a handheld thermal viewer that is easy to carry, quick to operate, and capable of more than passive observation. That makes the series well suited to hunters who want to locate heat signatures before moving into position, landowners and pest controllers working after dark, and search teams that need a thermal device with recording and connectivity features built in.

About the ATN OTS 4T 384 1.25-5x

The ATN OTS 4T 384 1.25-5x is the wider-view model in the 384-series lineup, built for users who need to scan ground efficiently and pick up heat signatures quickly. Its 1.25-5x magnification and 16.00 ° field of view make it especially practical for woodland edges, fields, and general observation where situational awareness matters as much as target recognition. The 750.00 m detection range gives it enough reach for spotting animals or people at distance, while the lower starting magnification keeps the image easier to manage when sweeping larger areas.

The thermal core uses a 384x288 sensor, paired here with a Micro - HD display at 1280x960 resolution. In practice, that combination gives the user a clear viewing image for handheld thermal work, while the digital architecture adds functions that extend the monocular’s usefulness beyond simple detection. Built-in video recording at 1280x960 allows observations to be saved for later review, and WiFi connectivity supports wireless sharing and streaming in the field.

ATN also gives this model the practical handling expected from a handheld thermal monocular. The 850.00 g body remains substantial enough for steady viewing, while the 18.00 h Li-ion battery life supports long sessions without constant power management. Waterproof and fogproof construction helps the unit stay usable in wet weather and changing temperatures, making it a sensible choice for hunting, surveillance, and recovery work where thermal imaging often matters most after dark and in poor visibility.

About ATN

ATN was founded in 1995 in Silicon Valley, California, and focuses on night-vision, thermal-imaging, and digital day-and-night optics. The company is now headquartered in Doral, Florida and is known for building digital optics that combine imaging hardware with onboard electronics and software-driven features. Its product range covers traditional image-intensifier night vision, digital night vision, and thermal imaging devices.

In this category, ATN is particularly associated with its Smart HD approach, which brought features such as onboard recording, wireless connectivity, and integrated sensors into field optics. The company introduced the X-Sight II HD digital day-and-night sight series in 2015, and in 2018 it introduced products based on its Obsidian 4 Dual Core platform. That background is directly relevant to the OTS 4T, which reflects ATN’s emphasis on combining thermal detection with digital functionality in a compact handheld format.
