The camera will usually have volume controls that allow you to adjust the sound level for both the incoming audio and the outgoing audio. This is typically done through an app or software that is used to control the camera.
The volume control is important because it allows you to adjust the audio level to fit the specific environment you are monitoring. For example, if you are monitoring a quiet room, you may want to turn down the volume to prevent any unnecessary noise. On the other hand, if you are monitoring a noisy environment, you may want to turn up the volume to make sure you can hear everything clearly.
Volume control on a two-way voice camera may be limited by the camera’s hardware. If the camera has low-quality speakers or microphones, you may not be able to adjust the volume as much as you would like. Additionally, the sound quality may not be as clear as you would prefer. In these cases, you may need to consider upgrading to a higher quality camera with better audio components.
