Connect a PTZ device to the GXV3500
1. Connect the PTZ device to GXV3500 by using the RS-485 port. Connect the A pin to
the positive cable of the PTZ device. Connect the B pin to the negative cable of the
PTZ device. The PTZ device has its own power
2. Click Advanced Settings > PTZ; in PTZ page, configure the PTZ Protocol and
Baudrate according to your connected PTZ device.
3. Click Save and reboot the device to apply all changes.
4. Use those PTZ buttons on the homepage to tilt, pan the GXV3500 and also adjust the
speed.
NOTE: GXV3500 itself does not support PTZ. The users can connect a PTZ device to the
GXV3500 via RS485 pins to pan, tilt and speed.
The FOCUS function may not work as many dome cameras support auto focus.
Press and hold the corresponding control button to adjust the pan, tilt, and speed.

GXV3500 Alarm Event
The GXV3500 supports alarm inputs, for example, infrared detector, smoke detector and so
on. Follow the steps to make Alarm Input work:
1. Connect alarm input equipment to the GXV3500.
2. Set up the alarm event time schedule.
3. Configure the alarm actions which you would like the GXV3500 to take when alarm is
triggered.
How Alarm Input and Alarm Output Work
Alarm-in is the alarm input port; users are able to connect sensors such as infrared sensor,
smoke sensor or light sensor to it. The detectable signal voltage range for alarm-in is from
2.5V to 45 V NOTE: Please do not connect a device that has a signal voltage that is higher
than 60V, this will damage the IP encoder/decoder.
Internally, the Alarm-out uses relays as a switch (30VAC/2A); users can connect devices such
as alarm siren or alert light to this port. Under normal circumstances, the circuit is open.
When there is an alarm event, the GXV3500 will close the circuit to trigger the alarm.
