Add a mic or speaker(sold separately), and as you watch on a monitor you can tell an employee how to change a store layout or discuss a problem on the production line. This kind of real-time conversation is ideal for clear, smooth communication and top work efficiency even when you're away. The camera server has an SD card slot which allows you to record images directly from the camera to an SD Memory Card (sold separately) in the server without going through the network. Or to monitor comings and goings, you can use the camera's motion detection function to record an image every time something moves.
