Pulsar Telos LRF XT50 Thermal Camera

Pulsar Telos LRF XT50 is the flagship model of the Telos series and a very high-resolution thermal camera for demanding hunting, game observation, and long-distance surveillance. Its key strengths include a 1280 x 1024 pixel HD thermal sensor, System NETD below 20 mK, a wide 17.5-degree field of view, a detection range of up to 2300 metres, and an integrated 1200-metre laser rangefinder. The XT50 is designed especially for users who want to view a wide area at once while retaining as much detail as possible even at long distances and when using magnification.

The 1280 x 1024 pixel thermal sensor with a 12 µm pixel pitch is one of the XT50's main selling points. The high HD resolution helps distinguish the shape and details of a target considerably better than lower-resolution thermal sensors, and retains more usable information even when using digital magnification. This is particularly useful when a thermal signature is visible at a long distance and the user needs to determine what they are actually looking at, rather than simply detecting a heat source.

The thermal system has a Sensor NETD below 40 mK and a System NETD below 20 mK. Good system-level thermal sensitivity helps reveal small temperature differences, for example in wet weather, fog, or situations where the temperature of an animal and its surroundings are close to one another. The 50 Hz frame rate keeps movement smooth both when moving the camera and when tracking a moving animal.

Wide field of view and long detection range

The fast F50/1.0 objective lens provides a stated detection range of up to 2300 metres. At the same time, the XT50's 2x base magnification and exceptionally wide 17.5-degree field of view, equivalent to 30.7 metres at 100 metres, make systematic observation of large areas significantly easier.

A wide field of view is an important practical feature especially in fields, clear-cuts, and other open or varied terrain. The user does not need to sweep the surroundings back and forth with the camera as much, allowing animals to be found more quickly and moving targets to be kept in view more easily.

The magnification range is 2-16x and up to 24x with the Zoom Boost function. The benefit of the high sensor resolution is particularly apparent here: when magnifying, more detail remains in the image than with a lower-resolution thermal camera. Pulsar has also equipped the XT50 with electronic image stabilisation, which helps steady the image, especially at higher magnifications.

1200-metre laser rangefinder

The integrated laser rangefinder measures distances up to 1200 metres with +/-1 metre accuracy. Measurements can be taken directly with the thermal camera without a separate rangefinder, speeding up target distance assessment and reducing the uncertainty associated with visual estimation.

The rangefinder is particularly useful in open terrain and in darkness, where judging distances can be surprisingly difficult. It can be used for both single measurements and continuous scanning.

Full HD AMOLED display

The XT50's high-resolution thermal image is complemented by a 1920 x 1080 pixel Full HD AMOLED display. The display's high resolution enables inspection of the details produced by the sensor without the display becoming a limiting factor in the system.

AMOLED technology provides high contrast and fast response, keeping the image clear even when tracking a moving target. Together with electronic image stabilisation, the display makes it easier to examine target details at higher magnifications.

Recording, 128 GB memory and wireless connectivity

The Telos LRF XT50 includes 128 GB of internal memory for recording observations. Video and photo recording resolution is 1440 x 1080 pixels, allowing hunting and wildlife observations to be saved directly on the camera without a separate recording device.

The device supports both 2.4 and 5 GHz Wi-Fi connectivity as well as BLE 5.0 Bluetooth. With the Stream Vision 2 app, the thermal camera can be connected to a smartphone for purposes such as transferring recordings, viewing the image, and software updates. The XT50 also supports the Stream Vision Ballistics app.

The XT50 model also features NFC quick pairing. A compatible phone can be paired with the Stream Vision 2 app by bringing it close to the device, without the usual need to search for a Wi-Fi network and enter connection details.

Telos Upgradeability - an upgradable thermal camera

The Telos series is designed for a longer-than-usual service life. Telos Upgradeability makes it possible to upgrade certain device components to newer options through Pulsar's upgrade service, rather than having to replace the entire thermal camera as technology develops.

This is a particularly significant feature in a premium-class thermal camera expected to remain in use for several years. Upgrade options depend on the model and the upgrade services offered by Pulsar at the time.

Designed for demanding outdoor use

The Telos LRF XT50's rubber-coated plastic housing provides a secure grip even in wet and cold conditions. The symmetrical button layout, together with the focus and zoom rings located near the objective lens, enables use with either the right or left hand.

IPX7 waterproofing allows the device to be used in rain and wet conditions. The operating temperature range is -25...+40 °C, making the camera well suited for year-round use in Nordic conditions.

Power is supplied by a replaceable LPS7i 6400 mAh Li-Ion battery, with a stated operating time of approximately 8 hours at 22 °C. USB Type-C Power Delivery enables the use of a 5 or 9 volt external power source during long observation sessions.

Recommended use: The Pulsar Telos LRF XT50 is especially suitable for hunters and demanding wildlife observers who operate in open or varied terrain, at long distances, and in situations where target identification is more important than mere detection. The 1280 x 1024 HD sensor helps solve the problem of lower-resolution thermal images losing too much detail when magnified. The wide 17.5-degree field of view makes scanning a large area easier, electronic image stabilisation makes high magnification more usable, and the 1200-metre laser rangefinder eliminates the need to estimate target distance visually or carry a separate measuring device. The XT50 is a well-founded choice for users who want the most accurate possible image, a large detection area, long-range distance measurement, and comprehensive recording and connectivity features in a single handheld thermal camera.
