How do I connect a PTZ device to work with my GXV3504?

After connecting the PTZ controller to the GXV3504(See User Manual for RS485 connection setup) and configuriring the correct PTZ protocol, you can then set the address code. Most PTZ devices have ON/OFF switches that allow address code configuration. To allow the PTZ control of the GXV3504, it must match the address code of the GXV3504. For example, the address code of the GXV3054 is 1-2-3-4. The user will also set the PTZ address code to 1-2-3-4 using the ON/OFF switches. (Please refer to the PTZ user manual to see how to setup the ON/OFF switch to match address codes.)

How do I disable audio from the camera during a SIP call?

You cannot disable the audio during a SIP call between IP phone and camera. By current design, the IP camera will always have microphone enabled (if supported) during a SIP call. However, you can enable "Disable audio in SIP call" to prevent the camera from outputting your voice to speaker or audio line out. If you wish to view the camera without hearing the audio from the camera's microphone, you can use the live stream interface of the camera's web gui or use the RTSP url to stream the camera.

How does the Alarm_Input & Alarm_Output work?

The Alarm_In port needs DC voltage less than 15V. Users are able to connect 3rd party sensors such as infrared sensor, smoke sensor or light sensor to this port.

The Alarm_Out port can be connected to either AC or DC circuits with 125VAC/0.5A or 30VDC/2A. Users can connect 3rd party 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 device will close the circuit to trigger the alarm.

Note: This info can be used for all of Grandstream devices with Alarm_In/Alarm_out ports, e.g. GXV3500, GXV3504, GXV3601_HD, GXV3611_HD, GXV3651_FHD and GXV3662HD/FHD.

If one stream, primary or secondary, is set to H264, then motion detection will take effect. Only when both primary and secondary are set to MJPEG will the motion detection not work. Motion detection is based on H264. MJPEG is not support for this feature.

Will the GXV3500 Decoder/Encoder be compatible with third party cameras?

Encode Mode: (Analogue Camera)

Generally, most 3rd party analogue cameras will be digitized to IP Camera when connecting to GXV3500 BNC port at Encode Mode.

Decode Mode: (IP Camera)

Whether GXV3500 can decode the data stream from a 3rd party IP camera is dependent on how the stream was encoded. GXV3500 utilizes the RTSP stream and is capable ONLY H.264 formats decoding (so MJPEG is out of luck). General rule of thumb is if the RTSP stream of 3rd party IP Camera can be viewed by VLC Player (free open source media player software), the GXV3500 will very likely be able to decode the stream, but no guarantee due to the variety of H.264 encoding implementation by different IP Camera vendors.
