HOW TO CONFIGURE SIP OPEN DOOR VIA GRANDSTREAM
NVR/GVR355X AND WEATHERPROOF SERIES IP CAMERAS
Unlike plastic case indoor camera GXV3611IR_HD, the metal case outdoor IP66 weatherproof
IP cameras GXV3672, GXV3674 and GXV3610 series do not have built-in Alarm_In and
Alarm_Out interface. But when combined with Grandstream GVR355X, SIP Prox or IP-PBX, the
GVR355X’s built-in Alarm_In and Alarm_Out interface can be used to connect to related 3rd
party device like Door Bell/Intercom and Relay or Door Strike, to accomplish the SIP Open Door
function when configured with related SIP IP-PBX.
The benefit of such solution is that the GVR355X can only record all the person pressed the door
bell and door can be controlled (local or remotely) via video SIP calls, either via Grandstream IP
video hard phone like GXV3240 or GXV3275, or Grandstream GS_Wave soft phone (pending)
running on Android or iOS.
Following is the example of how to configure this feature. Recommend using latest firmware for
all related Grandstream device. The FW used in below example are:
•GVR355x FW: 1.0.1.29
•GXV3610/3672/3674: FW: 1.0.3.13
Firmware beyond the above versions are required for this feature to function properly.
GXV3672/GXV3674/GXV3610 (IP Camera) Side:
•Basic - SIP Setting:

Make sure configure correct SIP Proxy or IP-PBX by using either FQDN domain name or IP
address. Also fill in extension and password, save the setting and make sure the IP camera is
registered to the SIP server, as shown in Figure 1, the green “Online” status will be displayed
once the IP camera registered to the SIP Proxy or IP-PBX.
At the “Phone List for Alarm Out”, please fill in the extension of the IP video phone to receive
the Alarm_Out calls, this could be Grandstream SIP video hard phone or software phone. Make
sure the video phone is indeed registered to the SIP Server or IP-PBX.
Figure 2-1: IP Camera Basic Settings – Alarm Out Phone Number
Once click “Add”, the phone number will be added as shown in below:
Figure 2-2: IP Camera Basic Settings – Alarm Out Phone Number
In this example configureation, the IP camera with extension number 809, once Alarm_In
(sending from GVR355X via the Door Bell Operation) triggered, will make SIP phone call to
extension 806, the IP Video Phone configured to receve the Alarm_Out call to execute the open
door operation. The IP video phone could be Grandstream GXV3240/3275 hard phone, or
GS_Wave soft phone runing at Smartphone, like Android or iOS (Pending).
This finished the SIP related configuration on IP Camera side.
NOTE:
Make sure to DISABLE the Voicemail or Faxmail at SIP Proxy or IP-PBX side for the
extension that receving the Alarm_Out call. (Extension 806 in the example).

GVR355X (NVR) Side:
GVR355X has to configure the “IO Alarm Config” correctly to allow the “SIP Open Door”
feature function properly.
•
Software Configuration
GVR355X can be configured either via Local View interface or WebGUI interface.
Below example is using web interface of GVR3552, the GVR3550 is similar:
Figure 3: Open Door Configuration
•Alarm_In Port:
Slelect “Input Port” from pull-down selelction, this port has to be connected to the wire
connecting to the Door Bell or Intercom circuit.
•Alarm_Out Configuration:
Select “Open Door Request” to enable “Open Door” feature.
Once selected, the system will automatically enable the Alarm Input port just chosen.
Select the related IP Camera from the “Authenticaton Camera” pull-down selection (Camera 2 or
Channel 2 in this example), also select related “Open Door Port” from the pull-down selecton.
(Alarm_Out port 2 in this example).
Make sure the related Open Door Port has physical connection or circuit to the door strike.
Fill in correctly the digit key to open door, and the Alarm Duration which is the timer the
Alarm_Out port will send signal to relay to restore the state (10 seconds in the example).
NOTE:
Enter “#” key following the digits key to execute the operation.

Hardware Wiring
Below are illustration of wiring diagram for the GVR355X.
Figure 4: Alarm_In and Alarm_Out Connection Circuit Sample for GVR355X
NOTE:
The Alarm_In and Alarm_Out circuit connection has to be similar to above circuit
diagram and meet following requirement:
Alarm Input
Vin<15V, PINs (1.02KΩ)
Alarm Output
125VAC/0.5A, 30VDC/2A, Normal Open, PINs
The Alarm_In circuit (like above photocoupler), if there is any voltage change smaller
than 15V, as specification listed), the GVR355X Alarm_In port will detect it and trigger
the action and event
The minimum duration is 500ms for the Alarm_In to trigger and the minimum voltage
change should be bigger than 3V.
Higher voltage and wrong polarity connection are prohibited because this will damage
the devices. So please wiring correctly and do NOT connect the polarity wrong.
Any Door Bell circuit should be able to connected as Alarm_In, just make sure the
polarity connected correctly and make sure the voltage change meets the requirement.

Figure 5: Alarm_In andd Alarm_Out Wiring Diagram for GVR355X
NOTE:
Alarm_In will share the “G” as Ground, make sure to connect the “Negative” or “-“ cable
into the interface marked with “G”.
Alarm_Out port marked with A, B, please make sure to connect “Positive” or “+” cable
into the port with “A”, the “Negative” or “-“ cable into the port with “B”. (In the
example, Port 2 configured as Alarm_Out operation to Open Door, see the cable
connected into the GVR3552).
Alarm_Out duration in the above example is configured as “10 seconds” at the
GVR355X. So the Alarm_Out will act for 10 seconds before revert back to previous
state. In the example, the default is circuit “Open”, when Alarm_Out triggered, the circuit
state changed to “Close”, as illustrated below for 10 seconds and then switch back to
prevoius “Open” state.
If connecting to a multimeter, you will see the Ohm changed from unlimited to serveral
hundred Ohms during the Alarm_Out port action. See below Figure 8.
Also a “click” audiable relay switching sound can be heard if closing enough to the
GVR355X when the inside circuit doing the job.

Please contact Grandstream technical support if followed the above instructions but the
feature still not working as expected. Please make sure the SIP Proxy or IP-PBX indeed
have the related IP Camera and IP Video Phone registered.
