Theia Debuts 5-Megapixel, IR Corrected Telephoto Lens

Apr 12, 2011

Theia Technologies announces the expansion of its line of high quality, megapixel resolution lenses with the new SL940 telephoto lens.

With 5 megapixel resolution, IR correction and its compact size, the lens provides a combination of features rarely found in other telephoto lenses available on the market today.

The new SL940 features a focal range of 9 to 40mm providing 36-degree to 7-degree horizontal field of view. With its 5 megapixel resolution, 4.5x optical zoom and 16x digital zoom capability the lens allows the user to drill down into the image capturing subjects in high detail.

The lens is IR corrected, maintaining focus in both visible and Near Infrared areas of the light spectrum and can be used with true Day/Night cameras.

And the lens is only 49.5mm long allowing it to fit in most mini-domes. Many telephoto lenses on the market are 3 inches long or more, often making them unusable in all but the largest and bulkiest dome enclosures.

The lens was developed to offer the security industry another unique product not found today. “Theia developed the SL940 lens to respond to continued security industry complaints about the small offering of good quality megapixel lenses available on the market. The SL940 telephoto lens complements our family of ultra wide undistorted lenses, using patented Linear Optical Technology, expanding the fields of view available in high megapixel resolution lenses,” said Jeff Gohman, president of Theia Technologies.

The CS-mount lens was designed to cover 1/2.5" imagers and smaller including 1/3-inch, 1/2.7-inch HD size sensors. The lens is available in manual and DC autoiris versions.

A8V MIND

Hexagon’s Geosystems presents a portable version of its Accur8vision detection system. A rugged all-in-one solution, the A8V MIND (Mobile Intrusion Detection) is designed to provide flexible protection of critical outdoor infrastructure and objects. Hexagon’s Accur8vision is a volumetric detection system that employs LiDAR technology to safeguard entire areas. Whenever it detects movement in a specified zone, it automatically differentiates a threat from a nonthreat, and immediately notifies security staff if necessary. Person detection is carried out within a radius of 80 meters from this device. Connected remotely via a portable computer device, it enables remote surveillance and does not depend on security staff patrolling the area.
Luma x20

Snap One has announced its popular Luma x20 family of surveillance products now offers even greater security and privacy for home and business owners across the globe by giving them full control over integrators’ system access to view live and recorded video. According to Snap One Product Manager Derek Webb, the new “customer handoff” feature provides enhanced user control after initial installation, allowing the owners to have total privacy while also making it easy to reinstate integrator access when maintenance or assistance is required. This new feature is now available to all Luma x20 users globally. “The Luma x20 family of surveillance solutions provides excellent image and audio capture, and with the new customer handoff feature, it now offers absolute privacy for camera feeds and recordings,” Webb said. “With notifications and integrator access controlled through the powerful OvrC remote system management platform, it’s easy for integrators to give their clients full control of their footage and then to get temporary access from the client for any troubleshooting needs.”
