Ultra Low-Light Internal PTZ Lens (UPATZ)

The Claresys Ultra low light Pan, Tilt and Zoom Lens is a remote surveillance lens/camera solution with a unique internal optical scanning capability that provides covert pan and tilt operation and x35 zoom.  This allows the user to scan across a scene without the camera or lens moving.



Key benefits are the ability to gather video surveillance footage in low/poor lighting conditions with fast and easy deployment in hostile or exposed locations and reducing operational risk.  The 13 degrees of internal optical pan and tilt provides 230m of Pan at 1km, 460m at 2km and 690m at 3km, Therefore, exact positioning is not required and any fine-tuning or adjustment to a changing scenario can be carried out covertly from a remote, safe location.  A NATO/Stanag accessory mounting rail allows for a laser pointer or alignment scope to be fitted to aid alignment and the rugged housing is designed for IP68 environmental sealing therefore capable of surviving harsh environments.

UPATZ is easy to conceal in a covert hide or buried in the ground, simplifying the deployment and helping to reduce cost, complexity and power requirement.

Control is via Pelco D over industry-standard RS232 interface, ensuring compatibility with most common control systems.  The Lens’s intelligent control allows it to retain the position it was powered off in and be zoomed from this position the moment power is restored.  This eliminates the need for calibration cycles and provides maximum useful surveillance footage.

Lens can be purchased as a zoom only Ultra Low-Light Internal Zoom Lens (Long) (LIZL-L) and upgraded using Internal Pan, Tilt Module (long) (IPTM-L) at a later date
