How to Start/Stop the Recording Schedule of a Specific Camera via Server API?

Nx Witness doesn't have a direct API method to start or stop recording on certain cameras. But there is one called "saveCameraUserAttributes" that can change the additional attributes of a specific camera. We can use this API to enable or disable the recording schedule; in other words, start/stop recording. Visit the Server API page for more information.

How To enable/disable recording via Server API

1. Get the camera's full parameter list JSON through /ec2/getCamerasEx
2. Extract the parameter id (not physicalId). Since Nx Witness v3.0, it's possible to get the Camera ID directly from Nx Witness. You can find it by going to Camera Settings > Advanced tab.
3. Use the id as the index, construct the JSON with required parameters of /ec2/saveCameraAttributes, you can refer to the API documentation.
4. Change the parameter - scheduledEnabled to enable/disable the recording of the camera. True is enabled. False is disabled.
5. Send POST request to Media Server, using the API /ec2/saveCameraAttributes.

Authentication

All requests to the Server application are required to provide correct user authentication. The Server supports two types of HTTP authentication: basic and digest.

• Digest is more secure, the workflow is described in the API documentation.
• Basic is much simpler to use, just add user login and password to the link.
