Description
The Pixfra Arc range is perfect for:
- Bat surveys of buildings, particularly where a wider field of view is required (A613)
- Bat surveys of more distant structures and trees (remainder of range)
- Nocturnal bird and mammal surveys
- Hunting
- Search & rescue
Manufacturer warranty information
The Pixfra Arc Thermal Monocular is a compact and versatile thermal imaging device designed for wildlife enthusiasts, search and rescue teams, and ecology/conservation professionals. By detecting infrared radiation, it enables observation in complete darkness, fog, or dense vegetation. This monocular is ideal for non-invasive wildlife tracking, long-range detection, and general thermal imaging applications.
The Pixfra Arc A613 has been designed specifically for ecologists, with bat surveys in mind. The wider field of view of 32.3° horizontal x 25.8° vertical, facilitated by a shorter focal length, enables views of larger objects, closer up - perfect for surveying buildings for emerging bats.
Other models in the range have narrower field of view, but are still perfect for bat surveys where the user wishes to target specific roost features, or where it is not possible to position the camera close to the building. All models in this range meet the requirements set out in best practice guidance for bat surveys. Please see the Thermal Imaging: Bat Survey Guidelines published by the Bat Conservation Trust for more advice on how to choose your thermal imaging equipment for bat surveys.
The Arc range is also perfect for other applications, including nocturnal bird surveys, hunting, and search & rescue.
With built-in storage and recording capabilities, users can capture high-resolution thermal footage and images for documentation or review. This feature is particularly useful for surveyors who need to analyse their observations later or keep records of their observations.

Additional information
The built-in recording function allows users to document and revisit their observations. Whether for research, evidence collection, or sharing experiences, the ability to store thermal images and videos enhances the usability of the Pixfra Arc Thermal Monocular.
Unlike traditional optics, which depend on visible light, thermal monoculars detect heat signatures, making them ideal for low-light and obstructed conditions. This technology enables effective monitoring through fog, smoke, and vegetation while ensuring minimal disturbance to wildlife.
The Arc range enhances collaborative fieldwork by allowing simultaneous viewing across multiple users. Using the free Pixfra app, the device can stream its live feed to up to four smart devices within a 20-metre range. This enables every group member to observe key moments - such as the emergence of a bat or the movement of a nocturnal mammal -without needing to crowd around a single viewfinder.
The Pixfra app is available free of charge for both Android and iOS platforms.
