Long range IR technology for perimeter surveillance

Ascendent Technology Group : 17 July, 2009  (Technical Article)
Ascendent Technology explains how its Terra range of long distance day and night IR camera systems can be used as part of an integrated surveillance and access control environment
Long range IR technology for perimeter surveillance
The terra series of long range IR cameras incorporates highly tuned EMCCD imaging equipment that is optimized for long range surveillance to render superb detail in rich colour by day. While At night or in 0lux environments, the Terra series intensifies IR light on an electron level while eliminating glare from visible light rendering clean crisp monochrome images. This allows the Terra series to capture minute details at great distances for 24/7 indisputable identification resulting in the prosecution of trespassing parties.

The IR optimized optics for 24/7 use enable long range surveillance up to 60,000Ft (20KM) by day and 24,000Ft (8KM) in 0lux (complete darkness) while maintain excellent clarity making it the choice for homeland security, critical infrastructure and military logistics world wide.

Ascendent IRBF blocks visible light emitted from streetlights, and other bright sources from (380-800nm) while increasing sensitivity to IR and laser illuminators (840-870NM). DNR and 50DB eliminates blooming, streaking and video noise along with other complications usually associated with IR imaging allowing it to overcome virtually any ambient lighting environment including fog, city, waves, complete darkness etc.

The Terra series PTZ is a true 24/7 surveillance solution with viewing distances up to 60,000Ft (20km) by day and 24,000ft (8km) at night. An endless 360 degree PTZ driver allows it to pan tilt and zoom with micro-step technology for quick accurate manual control or automatic operation via intelligent Video Analytics for flawless uncompromising 24/7 operation.

Although the terra series is extremely sophisticated imaging equipment it is operated by an intuitive user friendly interface that is controlled using a mouse. The PTZ can also be controlled by a 3 axis joystick and since the illumination atomicity syncs with the zoom lens its is just as easy as operating a standard PTZ while maintaining its Superior performance.

The Terra series is comprised of high quality components precision engineered for unparalleled performance and reliability. The heavy duty PTZ driver implements brushless motor technology for endless 360 degree panning and tilting in increments as low as 0.01 degree. The ASC-500MIRF has an industry leading MFTB of 100,000 hours IR lifetime. The lasers have an MFTB of 10,000 hours and can illuminate distances of up to 8KM while only drawing 1.7W power. The Continuous zoom IR corrected Optics (10-1000 2x 20-2000mm and 12.5-750nm 2x 25-15000mm) are manufactured by Raymax and Fujitsu. All these components can be integrated into a rugged IP67 stainless steel, explosion proof housing to suite installation in the most hazardous environments in the world.

The terra series is more then simply a long range camera, it is an complete security management solution that uses IP, analogue and MegaPixel cameras for hybrid operations for limitless camera options. Not only a CCTV management solution, it can also integrate with access control, radar detection and sensors to streamline and increase efficiency of all security systems. These systems can be controlled via wires or wireless networks to effectively control the system up to 500KM away over a LAN network if they have sufficient privileges to do so.

As mentioned above the Terra series has the ability to effectively synchronize CCTV, sensors and access control, allowing all essential security control to be performed using only one system which significantly reduces training and personnel requirements. To further enhance cost savings, the Terra Series allows the system to take advantage of prior security investments and upgrade existing CCTV cameras, sensors and access control to provide an affordable solution without compromising performance.

The terra series PTZ is designed for unmanned operation, the sensors can be set to send telemetry to the PTZ when activated to automatically focus where a perimeter has been breached. Additionally, integrated AVA automatically acquires license plate, facial details, and tracks intruders for absolute perimeter control. AVA's intelligent object detection/tracking /classification and video analysis is controlled by user specified parameters for accurate unmanned 24/7 operation.

AVA (Ascendent Video Analytics) is an innovative product that overcomes the constraints of traditional CCTV monitoring systems. It boasts a180° panoramic display that allows monitoring of a wide area without blind spots by using 5-8 fixed cameras with a terra PTZ that optically zooms and acquires identifying details such as license plate or face. All these events are recorded using a proprietary, self-contained video/event database engine that can easily be accessed by a graphical easy to use interface. Unlike other video analytics, it does not need an external DBMS such as MS-SQL, MS-Access, Oracle, etc. Video recording/search/playback/export can be performed based on events as well as time.

With today's growing security needs, a one size fits all approach no longer works, Ascendent believes every Customer represents its own specific unique challenges and requirements. Through the years, the role of the security industry has dramatically changed and gone far beyond simply protecting assets, it has evolved into a vital operational tool that drives the most successful Governments, corporations, global enterprises and a host of other industries worldwide. Ascendants' tailored customized Approach allows you to design and configure a complete Security solution based on your requirements instead of manufactures specs and limitations with seamless integration of Video Access control, POS and critical data management. For Projects over 2+ million, Ascendent's engineers and technological partners will design a system based solely on your specification and requirements offering unparalleled performance and support. Ascendent saw the need for a Dynamic versatile Solution that grows when you grow and changes as your company changes. Ascendent is proud to release its X3 and X4 platforms to tackle the most Complex Security demands for Government Corporate and Global enterprises.
