Analysing recordings of gunshots could help save endangered species around the world by identifying poacher hotspots.

New technology has been developed by international conservation charity the Zoological Society of London (ZSL) and Google.

Acoustic sensors placed in nature reserves or safaris can record events up to 1km (0.6 miles) away.

It uses artificial intelligence to analyse audio for gunshots, alerting anti-poacher patrols.

Conservationists currently rely on camera traps to track poachers. The traps are activated by movement, and limited to close range within line of sight.

But acoustic sensors are cheaper, record continuously and can detect events further with a 360-degree radius.
