Phone Call-In and Camera Remote Control Using VoIP or ISDN

If your camera is connected to a network or to ISDN, you can call the camera from any SIP phone (for Voice over IP, short VoIP telephony) or from a regular telephone.

You can then remote-control the camera using the phone's touchtone keys. The telephone must support tone (Dial Tone Multi-Frequency) dialing, sometimes also called touchtone dialing. If you are using VoIP telephony and a SIP provider, this provider also has to support DTMF dial tones (for further information, see the VoIP Settings help page).

Note: This feature is not available for Web and Basic models.


Phone Call-In Settings

In order for the camera to answer VoIP and ISDN phone calls, you need to set the corresponding options in the Phone Call-In dialog first.

Among other parameters, you can set the phone number (MSN) to which the camera will answer in this dialog. In addition, you can select a message that the camera plays when answering a call.

Description of Parameters

Parameter Description
Phone Call-In

Select if and how you would like to allow voice phone calls (from a normal phone and from VoIP phones) to the camera.

If the VoIP options are not shown, you need to activate VoIP in the VoIP Settings dialog and enter the desired settings.

Camera MSN

Normally, three MSNs (Multiple Subscriber Number) are assigned to every ISDN network termination. By its factory default settings, the camera will answer to every MSN that is called on the ISDN S0 bus.

The camera software can assist you in finding and entering the MSN. Call your camera and reload this dialog or re-open it by clicking on this link: Phone Call-In. The last MSN called is displayed and you can copy it to the text box.

Note: This parameter is only displayed if Phone Call-In has been set to ISDN only or ISDN and VoIP.

Accepted Phone Numbers or SIP Addresses

The camera can be configured to either react to all incoming calls (not recommended) or only to the phone numbers and SIP addresses entered here.

In order to create a list of accepted telephone numbers, enter the accepted phone numbers and SIP addresses in the text box, one per line.

The camera software can assist you in finding and entering the phone numbers and SIP addresses. Call your camera and reload this dialog or re-open it by clicking on this link: Phone Call-In. The last calling phone number or SIP address is displayed and you can copy it to the text box by clicking on the corresponding button.

Note: If you leave this text box empty, the camera will answer every call. This is not recommended for security reasons.

Welcome Message Select one of the audio messages that have been stored using the Manage Audio Messages dialog. The camera will play this message upon every call.
PIN Enter a Personal Identification Number to avoid unauthorized access to your camera. If you have set a PIN, every caller needs to enter this number using the telephone keys. This will only work if you call from a phone that supports tone dialing (DTMF). If you are using VoIP telephony and a SIP provider, make sure that this provider also supports DTMF dial tones, since you will not be able to access the camera otherwise.
Audio Mode Select the audio mode to be activated after calling the camera:
No audio Audio mode is deactivated.
Listen After the voice message has been played, the connection remains active and you can listen to what is going on in the room.
Speak After the voice message has been played, the connection remains active and you can make an announcement using the camera speaker.
Intercom After the voice message has been played, the connection remains active and you can communicate with a person via the camera.
Intercom Settings The Intercom audio mode simulates an intercom device. To minimize distortions, the camera's microphone is deactivated while you speak.
Threshold The threshold controls the volume at which the audio channel from the telephone is put on the camera's speaker while the microphone is deactivated.
Duration Sets the minimum duration during which the microphone is switched off.
Hangup Call After The maximum connection time before it is terminated.
E-Mail Profile

After successfully connecting to the camera, you can send the last event image via e-mail by pressing "5" on your telephone's keyboard.

Select the e-mail profile you would like to use for sending. You can select any of the profiles created in the E-Mail Profiles dialog.
