TCP/IP SIP Colour Video Intercom System (VoIP)
Colour video intercom systems based on SIP (Session Initiation Protocol) use the same technology as Voice over IP (VoIP) calls. This allows a SIP intercom system to interface with the VoIP telephone network including business IP PBX systems and home based IP PBX systems.
So why should you consider a SIP based system?
SIP is a protocol for connecting devices which allows devices from different vendors to work together. There are many other intercom systems that use IP to connect but unless there is an App or an intermediate device they generally don’t connect to other devices.
Within the SIP intercom range there are subtle differences. Some systems will make calls between devices in the same range without an IP PBX. These use peer to peer SIP and rely on the devices being on the same sub-network. Others must register to an IP PBX or proxy to make calls in the traditional VoIP method.
SIP provides a standards based way of interconnecting different devices including telephones, tablets, some alarm systems, PC systems, some cctv cameras etc.
You should consider SIP based systems if you have an IP PBX and want to receive calls on your business phones or need to connect to another device now or in the future. Of course you may just want an intercom that has some additional features or like the look of the ones on offer.
SIP Video Intercom Components
Outdoor stations or door phones are located at the entrance to a property or area that requires permission to access. They may be a simple door bell style door station where a call is established to a person who can see and speak to the caller and allow access. Other systems may include keypads for calling different locations or allowing access through a pincode, RFID card readers, fingerprint reader, or bluetooth module to allow access without making a call. Generally these devices stream video for monitoring on other systems such as Network Video Recorders.
The C5 is a SIP based Door Station best suited for use with the H5 and HK16 indoor panels. They will also work with Grandstream phones and others have had success with Yealink multimedia phones. These are a cost effective door station with a low feature count that are ideal for installations where budget is a consideration. We import these from China and have had good success with them Note that they are becoming difficult to purchase as they are near end of life. We have limited stocks available.
The 2N® range of door stations are the top of the market for build, features and price. The 2 shown are from the modular Verso range with available modules for RFID card readers, fingerprint sensor, buttons, keypad (as shown), bluetooth sensor etc. These devices will generally work within most systems due to an enhanced configurability. They also work with the 2N Mobile service enabling connection to mobile devices with the 2N Mobile App (a high quality subscription service)
Fanvil offer a range of high end multifeatured door stations with a high level of compatibility with other systems. They are of rugged manufacture and best suited to industrial or business applications or residential where a high level of functionality and/or a tough exterior is required.
Indoor Panels / Phones
Depending on the system the indoor panel or phone maybe a dedicated touch panel, a telephone including multimedia phones, a tablet or smart phone. Extending the system outside the local network requires an IP PBX with external access (so that mobile devices can register) or an account with a VoIP provider. Note that not all VoIP providers support video so you may find you only have audio in this case.
As discussed previously, not all SIP intercom systems require an IP PBX to call between devices on the same network. This is generally limited to devices from the same vendor or IP calls from the door station to the indoor panels – in this case the call is to the IP address of the indoor device.
The H5 is a 7 inch SIP based poe powered touch screen designed to work in peer to peer mode with the C3, C5, C7, and A3K door stations and other H5 or HK16 panels. They have a camera built in so that video calls between units are possible in peer to peer or via a suitable IP PBX. These are made by DNAKE in China and imported by Active Online for use in residential communities and for sale to resellers and home owners. DNAKE have advised that they are nearing end of life and we are hoping to have an alternative in the near future. These screen are customisable (by Active Online) so that the customer can have a unique display panel with their own background image.
The HK16 is a 10 inch SIP based 12VDC powered touch screen designed to work in peer to peer mode with the C3, C5, C7, and A3K door stations and other H5 or HK16 panels. They have a camera built in so that video calls between units are possible in peer to peer or via a suitable IP PBX. These are made by DNAKE in China and imported by Active Online for use in residential communities and for sale to resellers and home owners. DNAKE have advised that they are nearing end of life and we are hoping to have an alternative in the near future. These screen are customisable (by Active Online) so that the customer can have a unique display panel with their own background image.
The 2N Indoor Touch is an Android based 7 inch touch screen designed to a very high quality and comes in poe and WiFi versions. The 2N Indoor Touch has high fidelity sound and excellent video quality and works in peer to peer mode with the 2N Door Stations. With the appropriate licence you can add other software to the panel such as Home Automation to consolidate other functions to the same panel.
The Grandstream Multimedia phones are available in 2 versions – the GXV3275 full touch screen or the GXV3240 touch screen with standard buttons. These devices should work well with all SIP based door stations. The have 6 SIP accounts so you can have 1 for intercom, and others for telephony through different providers.

“I have just installed the C5 Sip intercom panel from Steve and the team from activeonline.com.au. The intercom works really well with my SIP PBX and I can now answer the door from any SIP phone. This product was exactly what I was looking for, and was very reasonably priced.”
