Camera development kits speed home automation projects

Ready-to-use camera development kits for a range of applications in home automation, healthcare and industrial monitoring are offered by Avnet Silica. The advanced camera development kits are based on microcontroller platforms from NXP and STMicroelectronics.

According to the company, improvements in image sensors, processing power, power consumption and computer algorithms, have contributed to the growing use of embedded vision technology in automotive, consumer, healthcare and home automation, in addition to the established area of machine-vision based analysis in industrial applications.

The first kit is the Kinetis camera development kit, which is based on the Freedom K82F low-cost microcontroller development platform from NXP and uses the Kinetis K82F Cortex-M4 MCU. It also includes a TD next miniature TD7740-FBAC VGA camera module with flex connector, a 90 degree horizontal-field-of-view lens and IR filter. The K82F board can capture still images or stream real-time, low-resolution video with QQVGA resolution (160 x 120) at 25frame/s and deliver the still images or video through USB.

The Kinetis K82F is a configurable, low-current-consumption MCU with a FlexIO interface, which can also simulate protocols such as UART and SPI, as well as being capable of integrating a camera interface. The board is suitable for a range of video applications including low-resolution USB video streaming, monitoring systems, automated inspection, part sorting and identification, camera PIR sensors, security and surveillance, home automation, access control systems, as well as logistics and retail analytics.

The second offering is the low-cost, Mbed-enabled STM32F7 camera development kit. It offers low-current consumption, USB interfacing, a 4.3inch colour capacitive touchscreen display, and all the necessary hardware and software to enable the fast development of embedded vision for IoT, home automation and other video applications. The kit is based on the STM32F7 development board from STMicroelectronics and enables applications that require video, audio, multi-sensor support, graphics, security and high-speed connectivity features.

The STM32 Cortex-M7 microcontroller family comes with a variety of memory choices, and is offered with or without a JPEG codec. A range of TD next miniature camera modules can interface with the STM32F7 to deliver VGA quality or lower resolution video. Suitable applications are home automation, security and video surveillance or industrial monitoring systems.
