Calibrating your Gotya camera is an important step to ensure that motion detection is executing in the area of the camera viewfinder that you want, as well as detecting the right minimum object size. Setting the “active window” size and location determines where Gotya detects motion within the camera viewfinder. Setting the minimum object size enables you to filter out smaller objects and reduces false alerts. For example, if you want to detect a human size object, you can set the object size accordingly and therefore the movement of smaller objects (such as small animals, or tree branches blowing in the wind) will be filtered out.
You can calibrate the camera two different ways:
1) directly on the device you’re using as the camera by tapping on the calibration icon from the Gotya camera menu.
2) from the device you’re using as the camera remote controller using remote calibration
In some use cases, the placement/positioning of the smartphone that you’re using as the Gotya camera makes it difficult or impossible to see the camera viewfinder and to access the touch screen with your fingers to adjust the calibration settings. This happens when the phone is mounted against a wall or other barrier, is placed high up out of reach , or is otherwise difficult or impossible to reach. This is when remote calibration comes in very handy. Note: regardless of whether you calibrate the camera directly on the device or remotely, the calibration user interface/ user experience (UI/UX) is identical so you only have to learn one way to do it.
To remotely calibrate your Gotya camera, follow these steps (note: the camera and the remote controller must be connected to the Gotya Cloud Service. You connect to the Gotya Cloud Service by tapping on Service Account from the main menu, then logging in with your email address and password from the login screen).
1) Mount the device you’re using as the camera and take your best guess at aiming/orienting it to capture the area that you want to detect motion in.
2) Take a remote snapshot from the device you’re using as the remote controller to see if you’ve got the camera aimed correctly. Repeat 1) and 2) until you have the camera aimed correctly.
3) From the remote controller, tap on calibration.
4) You will see the calibration main menu. From here you can set the active window and the minimum object size as explained in the on-screen instructions.
5) In this example I’ve set the active window to detect motion of a person walking up the path, and filtering out motion that occurs above the active window in the viewfinder.
6) Next I set the minimum object size to roughly the size of a person, thereby filtering out smaller moving objects.
Now that I have the camera aimed and calibrated as I want, I can go ahead and start the camera and start motion detection, picture capture, and alerting when somebody walks on the path.
