Vizy AI camera review

Vizy setup

Vizy comes self-assembled (you can choose between 2GB, 4GB, and 8GB Raspberry Pi inside). A microSD card is pre-installed and all you need to do is plug it in and press the button to turn it on.

While there’s no fun in the build process, it is quick to get up and running. On first run, it uses Raspberry Pi’s Wi-Fi module to broadcast a network, which you can join from another computer. You can also connect via an Ethernet cable, which was the approach we favoured.

Once connected, you set up Vizy to automatically connect to a local wireless network so it connects whenever you boot up. Then, you can investigate the built-in software, divided into a range of apps and examples.

Built-in apps include a Bird Feeder (identifies birds), MotionScope (captures the motion of objects), and Object Detector (detects and logs classes with text alerts sent via Signal).

The examples are more simple, including OpenCV Edge Detection, Pet Companion, Pic Taker, TensorFlow Lite, and simple video capture. You can investigate the Python code for each example, to help you start to build your own apps. Detailed documentation at docs.vizycam.com includes a ‘Getting started’ guide, and information about accessories and applications, plus some simple API information. You can access the Python editor directly from the web interface, or log into the Shell and control Raspberry Pi directly.

These built-in programs ensure Vizy is a great platform for exploring machine learning possibilities. We particularly liked MotionScope, which captures the movement of an object (such as a bouncing ball) and provides detailed x, y, and z co-ordinates as graphs and a data dump. We can imagine this working incredibly well alongside calculus learning.

Meanwhile, the Object Detector and Bird Feeder can be used to analyse and respond to scenes, creating alerts for specific items. We had a lot of fun tracking a pet cat and sending alarms when she was detected on a table.

The camera is the equivalent of a Raspberry Pi High Quality Camera, although we’d be happier if it used an official camera offering. We also found the 1.5 m power lead to be a little short for some setups, mainly when we tried to move out into the garden for testing – although we note a Power over Ethernet Splitter (£15/$18) that would work well in this setting. There is also an optional outdoor enclosure with IP66 rating and a 4G LTE cellular network adapter.

Vizy provides you with a great introduction to image recognition that does a lot of the heavy lifting, allowing you to focus on practical projects. We think this would be ideal in a classroom setting.

Verdict

9/10

An interesting camera that allows you to quickly investigate image recognition projects.
