PTS Wireless Mesh Networks Distributed IP Video Surveillance
An increasing number of organizations are finding the advantages of networked video so compelling, legacy analog CCTV infrastructure is being replaced by distributed IP video surveillance systems. Distributed IP video surveillance provides the ability to view, control, share, distribute and record video anywhere within or outside the wireless mesh network. Intelligent systems synchronize the functions of access control, intrusion detection, sensors and enables greater control, versatility and can remove issues associated with single point of failure.
Advancements in digital pixel image sampling, used in today’s IP video cameras, surpass previous analog CCD (charge-coupled device) technology. The latest pixel image sampling methods now support low light and special lighting conditions, which was the only remaining benefit of CCD technology. With the introduction of megapixel imaging technology, megapixel IP video cameras now surpasses the industry’s previous highest resolutions defined by analog NTSC/PAL specifications. In comparison with today’s standard IP video cameras, this equates to a maximum of 0.4 megapixels (640 x 408 VGA or 704 x 480 (NTSC 4CIF) or 704 x 576 (PAL 4CIF), megapixel cameras are capable of achieving variations of 1.0 to 5.0 megapixels and greater in the future.
Strix Access/One provides the performance and quality of service required by today’s IP video cameras. With new imbedded intelligent algorithms and the latest innovations in motion detection, automatic compression selection, bandwidth and network optimization controls, as well as decision processing is built-in. In contrast with analog video where no intelligence is built-into the camera, although with the exception of high-end Pan Tilt Zoom (PTZ) cameras, all video is sent from the camera all the time.
