The world’s most trusted covert camera brand, used by law enforcement and private investigators worldwide.

02 — Looks Like a Normal Key Fob
Designed to look exactly like an ordinary car key remote. Clip it on your keyring and it’s completely undetectable in any environment, at any time.

04 — Silent Vibration Feedback
Know exactly what the camera is doing without looking at it. Different vibration patterns tell you when recording starts, stops, or changes mode — completely silent, completely discreet.
05 — 128GB Micro SD Included (Up to 256GB)
Ships with a 128GB card — holds approximately 4+ hours of 4K footage. Supports cards up to 256GB for extended recording sessions. Auto-overwrite keeps recording continuously.
06 — Motion Detection Recording
Switch to motion-activated mode via the app so the camera only records when something moves into frame. Preserves battery and storage for what matters most.
