This app will log vehicular traffic on a road or thoroughfare. It will also measure the speed of each vehicle and determine if the speed limit is being broken. It can be configured to text you if someone exceeds the speed limit that you set. The pictures are strategically taken to achieve the best possible view of a vehicle's license plate. Additionally, the pictures are uploaded to Google Photos if you wish.

Set up Vizy in the location that you think works best. Here are the general guidelines for setting up Vizy.

1. It's likely that you will need a zoom lens if you want to be able to read the characters on the license plate of a vehicle, but a zoom lens isn't necessary. Without a zoom lens will more likely get a picture of the entire vehicle without a zoom lens.
2. Vizy should be pointed at about 45 degrees with respect to the roadway, so that you can get a good estimate of the velocity, while also being able to see the license plate.
3. You have a choice of pointing Vizy 45 degrees to the left or to the right when facing the roadway. Bear in mind that if you point Vizy to the left (for example), you will get pictures of the rear license plate for cars traveling to the left, and you will get pictures of the front license plate for cars traveling to the right. Not all vehicles have front license plates, so pointing Vizy in the direction that is more important to you is a good rule of thumb. If it makes no difference, pick either direction.
4. An outdoor enclosure will be necessary if you want Vizy to stay outside, but it's probably a good idea to get the Radar application working without an outdoor enclosure first.

Begin by turning on your Vizy and pointing your browser to it. (Please refer to the getting started guide if you need help with connecting to your Vizy, etc.) Run the Radar application by clicking on the ☰ icon in the upper right corner and selecting Apps/examples. Then scroll over to Radar in Apps, then click on Run.

You'll be presented with a screen similar to below. The image at the top of the screen is the live video feed of what Vizy sees (for example, the road). Various controls (buttons, sliders) are shown below the video feed, which we'll describe in more detail.

To test, take your hand and swipe it across the image such that your hand appears on one side of the image and exits the opposite side of the image. It should detect your hand and estimate its speed as shown below.

You'll notice that when detecting vehicles (or, Vizy will display the picture of the bird it detected and a timestamp in the media queue as shown.
