Vulpelix is a source-available home and business security system: buy a license once — no subscription — and your footage stays on hardware you own, never a cloud. On-device AI detection, a real alarm with entry delay and per-person PINs, face recognition of enrolled residents, instant notifications with clips, and an open, documented MQTT API so anyone can extend it with any device. At its center is Accalia, a persistent local AI being migrated onto GPUs we own — because we hold our own AI to the same standard as the product: off the cloud, in your control. Available as a DIY self-install license or professional end-to-end installation.
