Bird and bat sound detection using your security cameras

Source preview: Bird and bat sound detection using your security cameras
AI summary

The article describes how the author repurposed his security cameras with microphones into a real-time bird and bat sound detection system using the open-source BirdNet-Go project. The system runs locally on Raspberry Pi or other hardware without cloud services, supports custom alerts for specific species, and integrates with Home Assistant and iOS applications.

Tip author’s note

It's wonderful what technology, AI and enthusiasm can achieve today. But if such an amateur project can detect and recognize birds and bats in real time around your home, what's the other side of this coin? What can a hacker do with your poorly secured home devices and the things inside them?

AI questions & answers
What are the main benefits of running bird detection locally instead of using cloud services?

Local processing provides lower latency, greater privacy, no monthly fees, and full control over your data. Audio never leaves your home unless explicitly shared, and the system runs continuously without depending on external service availability.

How many bird species can BirdNet-Go detect and how has this capability evolved?

BirdNET 2.4 originally detected about 6,000 species, while the newly added Google Perch v2 support enables recognition of up to 14,795 species. The author recorded over 418,000 detections of 271 unique species on his Southern California property during 2026.

What security risks are associated with such internet-connected home devices?

While the article does not address security threats in detail, the mention of sharing access via a public domain name through Cloudflare suggests risks from inadequately secured home-lab devices. Microphones in cameras can capture not just bird sounds but also speech, requiring proper security measures.
