Designed for Ecology, Birding & Conservation
Engineered with professional ecologists and wildlife researchers in mind, the Arc A613 is a versatile tool for a wide range of fieldwork applications, including habitat assessments, nocturnal species surveys, nest monitoring, and conservation studies. Its tripod-mountable body, expansive 32.3° field of view, and continuous video recording capabilities enable efficient, reliable data collection during extended field sessions.
Extended Wildlife Observation - Day or Night
The Arc A613 comes supplied with two replaceable, rechargeable batteries, offering up to 13 hours of continuous operation - making it ideal for overnight bat surveys, dawn bird watching, or nocturnal mammal tracking without the worry of downtime. Perfect for field ecology projects where uninterrupted monitoring is crucial.
Real-Time Viewing & Collaboration
Facilitating team-based ecological surveys and wildlife observation sessions, the Arc A613 connects to up to four smart devices via the free Pixfra app. This allows multiple researchers or birders to share live thermal footage within 20m, meaning key sightings can be shared instantly, whether you’re recording bat flight paths, spotting elusive birds, or tracking mammals after dark.
Lightweight, Rugged & Weather Resistant
Weighing less than 350g, the Arc A613 is designed for portable wildlife observation and field ecology. Its ergonomic, durable magnesium alloy casing protects against knocks and scrapes, while an IP67 waterproof rating ensures reliable performance in wet, misty, or muddy environments.
