Freescale Semiconductor addresses the growing market for digital video surveillance by developing a new royalty-free IP camera reference design based on the i.MX27 multimedia applications processor. With a comprehensive hardware and software package included, the i.MX27 IP camera reference design is aimed to enable OEMs to deliver IP network cameras that can offer crisp video streaming with ease.

Freescale's hardware-optimised reference design is engineered to allow OEMs and ODMs to easily differentiate their own IP cameras with added features, instead of focusing on core hardware/software design. The Freescale IP camera reference design implements the "must have" features for IP network cameras, beginning with H.264 compression technology to minimise network bandwidth and provide outstanding image quality. Other features include low-power operation, Power-over-Ethernet (POE) technology for seamless integration into existing networks, and D1 resolution image compression for sharp image detail and fast intruder identification.

Features
In addition to IP network cameras, the i.MX27 reference design targets the video and voice over IP (V2IP) market and can be used to create applications such as household doorbell products and consumer baby monitor devices. Consumers may view an enhanced live video feed—from their office, mobile or other connected product—allowing them to remotely track home security and receive email status notifications when a potential threat is detected. The design is ideal for V2IP applications requiring a camera, high-performance video compression, low-power operation and wired or wireless connectivity.

"This market-ready IP network camera reference design unlocks the powerful hardware capabilities of Freescale's i.MX27 multimedia applications processor," said Aaron Shagrin, director of enablement for Freescale's Multimedia Applications Division. "This proven hardware/software design allows OEMs to be creative in adding their unique software features while maintaining quick time-to-market to capitalise on the fast-growing trend towards IP cameras."

i.MX processors
The i.MX27 balances high performance with low power consumption through its intelligent combination of dedicated hardware video accelerators and a fast ARM926EJ-S core. This enables D1 resolution encode of H.264 and MPEG-4 Part 2 video with very low overhead on the ARM926EJ-S core, freeing it up to perform additional software tasks—all on a single SoC. In addition, overall system cost is reduced through intelligent integration of features, such as on-chip Ethernet 10/100 MAC, boot from NAND flash capability and peripheral integration for expandable memory and wireless connectivity.

The comprehensive i.MX27 IP camera reference design, including camera unit with tripod and comprehensive hardware and software packages, is expected to ship in Q2 08. Freescale's i.MX27 applications processor is shipping in volume at Rs.488.32 ($12.11) in 10,000 quantities.
