Firefly DL: Inference-On-The-Edge On-Camera

Deep learning is a robust tool developed for system designers, enabling them to rapidly automate subjective and complex decision-making processes and offer higher quality products and enhanced productivity.

Users can deploy their trained neural network to the FLIR Firefly DL powered by Neurotechnology and decrease the cost and complexity of systems by making decisions on-camera without using a host PC.

The Firefly DL camera is lightweight, has a small size and consumes minimal power, which together make it perfect for incorporating into handheld, desktop and mobile systems.

Deep Learning for Faster Deployment and New Possibilities

Through deep learning, users can rapidly develop and deploy precise solutions to overcome difficult automation issues.

Deep Learning Inference On-Camera

The cost and complexity of the system can be decreased by deploying the trained network to a Firefly DL camera. This prevents the need for a host system to handle classification tasks.

Ideal for Embedding into Compact, Portable Devices

The Firefly DL camera comes in a compact package of 27 × 27 × 14 mm, weighs just 20 g, and consumes only 2 W power.
