IP Security Camera Solutions: Enabling Security and Surveillance Systems

In an increasingly connected world, physical threats continue to be a major concern for governments, industry and consumers alike. With new video processing, motor control and audio processing capabilities, modern security systems include cameras that need to process a large amount of data and transform it into information that can help us identify threats and prevent them from becoming reality. Moderns cameras have IP connectivity, either via wired Ethernet, IEEE802.11 WiFi or HDBaseT, and many need to be deployed in harsh outdoor scenarios, where energy efficiency is of critical importance. Microsemi has been supplying products for the analog surveillance market since the mid 1970’s, and to the IP surveillance market since its inception. Microsemi’s comprehensive complete product portfolio for IP Cameras covers both their implementation and their deployment into virtually any field situation.

Microsemi AcuEdge™ Technology

New high-performance audio processors enable the streamlined development of IP cameras and Enterprise hands-free communication. Microsemi’s voice processing technology integrates industry leading features and dedicated firmware to deliver high-quality hands-free voice performance while reducing system design complexity.

Microsemi’s AcuEdge™ Technology audio processors (i.e. ZL38050) enable the streamlined development of IP cameras for HD Voice capability in 2 way hands-free audio. Microsemi’s AcuEdge Technology integrates industry leading features and dedicated firmware to deliver high-quality hands-free voice performance while reducing system design complexity.

Hands-Free Advantages

In complex noise environments such as large conference rooms and building lobbies, Microsemi’s AcuEdge Technology cancels echo, maintains a constant ambient noise (comfort noise) and converges during double-talk situations. While most solutions deliver only half-duplex operation, Microsemi’s proprietary algorithm is able to continuously converge and track changes in the echo path
to support full duplex operation. DVR, NVR or security camera users have difficulty trying to monitor a large number of video feeds for certain incidents, crimes or events. By adding audio to the surveillance camera, it will enable security personal at the control room to make judgement calls on security concerns Microsemi AcuEdge Technology will provide audio enhancement
to allow more accurate monitoring.

Microsemi Audio Processors complement SoC’s that process video in IP cameras, by adding enhancement features such as Beam Forming, Sound Locator, Far field microphone pick up (up to 20m), Automatic Speech Recognition and Sound Classification.

In our next posts, we’ll write about Diode Bridges, PoE PSE and PD ICs, and other topics relates to this subject.
