Thermal imaging cameras are part of the basic equipment of hunters and wildlife observers. They help with night-time use and in poor visibility conditions. The "Axion XQ19 Compact" offers relevant features at an entry-level price.
The thermal imaging monocular «Axion XQ19 Compact» from Pulsar is designed for hunting use. It is particularly suitable for night stalking and sitting game.
Lightweight and robust
Thanks to its compact size of around 14 × 4 × 7 centimetres and its low weight of around 300 grammes (including battery), the camera can be operated with one hand and is easy to transport. You can also mount it on a tripod using the 1.4-inch thread.
The housing is made from a magnesium alloy. It is designed to protect the inner workings from damage caused by knocks and drops. The device is also waterproof in accordance with protection class IPX7: it is unaffected by rain and can survive brief immersion in shallow water.
The runtime of the replaceable 3200 mAh battery is up to eight hours, according to the manufacturer. You can recharge it via USB-C.
High thermal sensitivity and a detection range of up to 750 metres
The camera has a sensor with a resolution of 384 × 288 pixels and a NETD value of less than 25 millikelvin, which guarantees high thermal sensitivity. This means that subtle temperature differences can be recognised even in rain, fog or high humidity. From eight colour palettes, you can select the one that best suits your current observation conditions.
The lens with a focal length of 19 millimetres and a light intensity of f/1.0 offers a basic magnification of 1.5 and a field of view of 34.7 metres at a distance of 100 metres. The device enables a detection range of up to 750 metres. This makes the camera well suited for observation at medium distances, for example when searching forest edges or fields.
Recordings and WLAN connection
The «Axion XQ19 Compact» has an integrated photo and video recorder with 64 gigabytes of internal memory. This allows you to document your observations and analyse them later or simply share them thanks to the WiFi chip. The camera connects to the «Stream Vision 2» app for Android and iOS. This also enables a live view on your smartphone.
