Yes, there is typically a limit to the number of cameras that can be connected to a single app. The specific limit can vary depending on the manufacturer of the cameras and the capabilities of the app itself. Some apps may have a limit of only a few cameras, while others may be able to support dozens or even hundreds of cameras.
It is important to check the specifications and guidelines provided by the camera manufacturer and the app developer to determine the maximum number of cameras that can be connected. Exceeding this limit may result in reduced performance, connectivity issues, or other technical problems. Additionally, connecting a large number of cameras may require a robust network infrastructure to ensure smooth operation.
