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. An IP PBX or SIP Server connects different devices together like a telephone exchange for SIP devices but SIP as a protocol can work as peer to peer (P2P) enabling devices using SIP to talk to each other directly.
SIP also allows intercom components to work with Cloud solutions providing enhanced feature sets and using the internet for networking rather than replacing or installing cabling.
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. Others still provide local SIP Server within the door station with all other devices registering to that server.
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 devices can also connect to some home automation systems and alarm systems that have built in SIP proxies or use SIP.
There are a number of free and subscription services that allow your SIP intercom to make a video call to an App on your mobile. Please ask us how if you decide you are interested in this feature.
Recent improvements to Cloud solutions offered by several manufacturers are exciting and offering enhanced capability to customers and property managers. Both 2N and now Akuvox are offering cloud services where you purchase a door station and monitor. This allows for centralised management as well as integration with Smartphones. With Akuvox SmartPlus you also can send temporary access to visitors (requires the appropriate door station) within scheduled time and date for service providers, family members, or for short term rental properties like Air BNB or similar.
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. SIP door stations also come in video and audio only varieties with the price proportionate to the features. Generally these devices stream video (Camera devices) for monitoring on other systems such as Network Video Recorders.
Akuvox have a range of door stations and monitors that use SIP protocol to connect. These intercoms vary in size and functionality from a single button audio door station to full touch screen apartment based intercoms with built in display functionality, body temperature meausurement for hands free access control, or face recoginition for hands free access control.
Akuvox have a range of monitors from 7″ to 10″ touch screens. Variations in capability and operating systems ensure there is a model that will suit most projects. The Android versions have extra capability to install Android Apps where centralising screens is desired.
Akuvox SmartPlus is a service that allows you to manage your system via a cloud service and also interconnect devices and Apps for calling and access control. SmartPlus requires a one time license purchased with an intercom system (door station and monitor). Please contact us to discuss SmartPlus for your intercom system.

*VIP Vision intercoms also support SIP for signalling and are not mentioned above as you require a VIP Vision touch screen to work with the VIP Vision door station. They are not recommended for integration in to existing SIP infrastructure but do work very well as standalone intercom systems. They have a free smartphone App for intercom calls (DMSS) that also works with the VIP Vision / Watchguard / Securview CCTV systems.
Indoor Panels / Phones / Receiving Units
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.
Systems with Cloud services generally use the cloud with many added benefits such as online management and smartphone calls.
Akuvox have a range of SIP touchscreens suitable for most SIP based intercoms. As with all these products they work best with door stations of the same brand allowing the system to be almost plug and play and all features available.
