智能视频流功能设置为物联网部署增加重要维度

通信

行业分析公司ABI Research预测，从现在到2020年，连接成像设备市场的价值将大幅增加 - 在此期间，复合年增长率（CAGR）将达到17％。
物联网（IoT）已经被确定为这种增长背后的驱动力。
存在基于物联网的成像技术将被证明是有利的各种不同领域。
其中包括楼宇门禁系统，监控设备，智能照明系统，婴儿监视器，智能设备和远程维护。
在将视频成像方面纳入物联网系统时，工程师必须了解基本标准。
它们如下：
首先，简单性至关重要。
视频子系统应该很容易实现（即使对于成像技术经验有限的工程师也是如此）。
由于大部分物联网应用需要电池供电运行，因此最小化功率预算是另一个重中之重。
通过合适的通信标准传输捕获的视频数据的能力也非常重要。
在大多数情况下，这是无线完成的（由于这可能提供的易于实施）。
还需要具有能够实现一定程度的智能操作的特征，以便在适当的时间启动视频流或静止图像捕获（例如，如果婴儿在睡觉时搅动，或者如果某人正在移动到用户的外面）
家）。
应该使用合适的云平台，以便有效地访问视频数据（亚马逊网络服务和谷歌云平台是最常见的选择）。
安森美半导体充分意识到未来低功耗物联网视频流应用的特点，并作为回应推出了高效的视频开发套件（VDK） - MatrixCam™。
该公司基于公司的AR023Z 1/3英寸CMOS图像传感器，具有1080p（1928x1088）分辨率的有源像素阵列，这种高度灵活的开源成像平台可显着缩短OEM产品开发周期，从而加快产品上市时间。
这种可用于生产的物联网摄像机解决方案可以使用便携式电子设备（如智能手机，平板电脑等）进行控制。
它支持多种接口技术，包括Wi-Fi（802.11b / g / n），以太网（10/100 Mbps），蓝牙低功耗（BLE）和Micro USB（用于电源，调试和固件升级）。
MatrixCam VDK可以连接到云服务，如Google Cloud Platform和Amazon Web Services，用于视频播放，支持视频点播（VoD）和30 fps直播。
智能流功能来自其系统唤醒机制。
这可以通过BLE或内置被动红外（PIR）传感器触发，通过该传感器可以确定运动（具有140°检测角度和10-15英尺检测范围）。
在唤醒时，向所分配的便携式电子设备发送推送通知，以警告用户需要检查实况视频流或静止图像内容。
MatrixCam VDKunit随附8 GB microSD卡，用于存储视频数据。
硬件元件由软件支持补充，可从软件设计文档下载（来自安森美半导体的关键技术合作伙伴）。
可以使用直观的基于Web的图形用户界面或通过专用移动应用程序配置VDK。

Industry analysis firm ABI Research predicts that the connected imaging equipment market will go through a substantial increase in value between now and 2020 - with a compound annual growth rate (CAGR) of 17% being witnessed over this period. The Internet of Things (IoT) has been identified as the driving force behind this ramp up. There are all manner of different areas where IoT-based imaging technology will prove advantageous. Among these are building access systems, surveillance equipment, smart lighting systems, baby monitors, smart devices and remote maintenance.
There are fundamental criteria that engineers must be aware of when incorporating a video imaging aspect into an IoT system. They are as follows:

Firstly, simplicity is paramount. The video subsystem should be straightforward to implement (even for engineers with limited experience of imaging technology).
As a large proportion of IoT applications will require battery powered operation, minimizing the power budget is another high priority.
The ability to transfer captured video data via a suitable communication standard is also of great importance. In most cases this be done wireless (due to the ease of implementation this potentially offers).
There also need to be features in place that will enable a degree of intelligent operation, in order for video streaming or still image capture to be initiated at appropriate times (such as if a baby stirs while sleeping, or if someone is moving outside the user’s home).
A suitable cloud platform should be utilized, so that video data can be accessed effectively (Amazon Web Services and Google Cloud Platform being the most common options).

ON Semiconductor is fully aware of the dynamics that will characterize future low power IoT video streaming applications and in response has introduced a highly effective video development kit (VDK) - MatrixCam™. Based on the company’s AR023Z 1/3-inch format CMOS image sensor, with a 1080p (1928x1088) resolution active-pixel array, this highly flexible open source imaging platform can markedly shorten OEM product development cycles and thereby accelerate time to market. This production-ready IoT camera solution can be controlled using portable electronic devices (such as smartphones, tablet PCs, etc.). It supports a wide range of interface technologies, including Wi-Fi (802.11b/g/n), Ethernet (10/100 Mbps), Bluetooth Low Energy (BLE) and Micro USB (for power, debugging and firmware upgrade purposes).MatrixCam VDK can connect to cloud services such as Google Cloud Platform and Amazon Web Services for video playback, with support for video-on-demand (VoD) and 30 fps live streaming. Intelligent streaming functionality comes from its system wake-up mechanism. This can be triggered either via BLE or the built-in passive infrared (PIR) sensor through which motion may be determined (with a 140° detection angle and a 10-15 ft detection range). Upon wake-up, a push notification is sent to the assigned portable electronic device to alert the user that a live video stream or still image content needs to be examined. The MatrixCam VDKunit is supplied with an 8 GB microSD card for storage of video data.
The hardware elements are complemented by software support, with software design documents available to download (from ON Semiconductor’s key technology partners). The VDK can be configured by utilizing an intuitive web-based graphical user interface, or via a dedicated mobile application. To learn more go to: www.onsemi.com/matrixcam.
