AXIS Q3505–V Fixed Dome Network CameraSystem OptionsPorts & DevicesI/O PortsThe Axis product provides two configurable input and output ports for connection of external devices. For information abouthow to connect external devices, see Connectors on page 73.To configure the I/O ports, go to System Options > Ports & Devices > I/O Ports. Each port can function as input or output:• Input as Open circuit – The input becomes active when the circuit is grounded by, for example, a REX device. It remainsinactive as long as its normal state equals its current status.• Input as Grounded circuit – The input becomes active when the circuit is opened by for example a monitor.• Output as Open circuit – The output port is in a non-conductive state when its current status is open circuit. The currentstatus of an output port can be changed by, for example, an action rule.• Output as Grounded circuit – The output port is in a conductive state when its current status is grounded circuit.Port StatusThe list on the System Options > Ports & Devices > Port Status page shows the status of the product’s input and output ports.AccelerometerTilt angle indicates the angle to which the camera’s lens holder is tilted. A 0° tilt is when the camera is pointing to the ground. It’spossible to have a tilt angle between 0 and 180°. To tilt to 180°, tilt to an angle of 90°, rotate the lens holder and tilt to a further 90°.Rotation angle indicates the angle to which the camera’s lens holder is rotated. The rotation range is between 0 to 360°. The camerais considered to be in a level position when the rotation angle is 0°, 90°, 360° or 270°.The leveling assistant that helps to level the camera is enabled by default. To disable it, de-select the Enable leveling assistant optionfrom System Options > Ports & Devices > Accelerometer and click Save.

These are available under System Options > Maintenance.Click Restart to perform a correct restart if the Axis product is not behaving as expected. This will not affect any of the currentsettings.NoteA restart clears all entries in the Server Report.Click Restore to reset most settings to the factory default values. The following settings are not affected:• the boot protocol (DHCP or static)• the static IP address• the default router• the subnet mask• the system time• the IEEE 802.1X settings• the focus position• uploaded applications are kept but must be restarted63
