MX Speed Dome Cameras can move side to side (pan), up and down (tilt), and zoom in and out (zoom). PTZ cameras are controlled either by a remote control, joystick, or computer software. PTZ stands for pan, tilt and zoom, derived from the fact that these cameras can be moved around remotely. Control is either by way of a standalone controller, or in some cases the DVR can be used to control the camera. When your DVR is accessible over a local network or the internet then camera movements are possible even when you are remotely viewing your CCTV system. The nature of a PTZ camera means the lens and electronics move around. Presets are an easy way for you to move your Speed Dome Camera from set location to set location.
