There was a time when an intercom was simply a pair of boxes with speakers joined by a couple of wires, with an audio amplifier somewhere in the mix. But intercoms have like everything else joined the digital age, so those two wires now carry a load of other functionality as digital signalling. [Aaron Christophel] installs these devices for a living, and has posted a fascinating reverse engineering video that we’ve also placed below the break.

Yes, a CCTV camera (optional) can be installed at the CCTV and GND terminals of the outdoor station No, to control actuations, a call from the entrance panel or alternatively the monitor self-start is necessary. Cameras / Monitors / Handsets / Entrance Panels & Buttons / Door Releases / Trades Timers / Speaker Units / Power Supplies Elvox Intercom devices are designed to be installed in any environment, thanks to the simplicity of installation and the flexibility of the configuration.Control over all video door entry system functions and settings is immediate, thanks to a particularly intuitive scrolling menu. In addition, all alerts are delivered by way of a similarly clear and uncluttered graphic interface. Intelligent and advanced, IP technology takes video door entry systems beyond their traditional limits: increased performance - whatever the building size - with contemporary, multiple audio/video communication between indoor stations and entrance panels with guaranteed, protected signal quality and a potentially infinite number of users. Expansion is as easy and simple as initial installation, also using existing LAN networks, without having to lay dedicated cabling. For efficient, high-performance communication At any time, you can adjust the call ringtone volume, talk/listen volume and display brightness, contrast and colour, even during a conversation. In the 1960s, the boom in production prompted frequent moves and changes of production facilities and the opening of a branch in Milan. The possibility of showcasing its innovative products at major tradeshows enabled Elvox to enter foreign markets.

Following further new thoughts regarding the development of both products and strategic and commercial direction, the 1990s marked a watershed in the history of Elvox. Already a leader in the video door entry system sector, Elvox now began to establish a strong position in the field of automation and safety systems. At the end of the decade, the opening of new market opportunities led to a well-researched entry into the world of telephony. The start-up of new business areas such as CCTV and the intensification of investments in research and development has enabled Elvox to expand its horizons to an even wider range of applications including the integrated management and control of residential, commercial, manufacturing and public spaces by combining its door entry products with a range of domotic controls. Designed to respond specifically to precise needs, Elvox video door entry systems with new IP technology support scalable solutions with a wide range of products offering advanced functions - including management of video door entry phone calls from smartphones and tablets - and making everyday life easier and safer. User-friendly modern design, additional programmable buttons, will allow flexible customization to meet your needs. Choose from various various sizes, colors and features . Ever since Elvox was founded by Orlando Miozzo in 1954, the company has been one of the key players in the intercom and, subsequently, video door entry system sector. Miozzo was an ambitious and intelligent man who was able to exploit his technical knowledge and expertise to launch Elvox onto the market with the determination necessary to cope with the transformation and growth typical of the Italian economy of the mid-1950s. Greater performance is ensured with the installation of the entrance panel at a height of approximately 1.6 m.

The kits are ready to use and do not require any particular programming; maximum distance between the entrance panel and the last monitor: up to 100 m with 1 mm2 You can automatically or manually capture images of the caller at the entrance panel and adding a micro SD memory allows you to capture more images or videos, which you can browse at your leisure The result is an interesting primer for anyone who fancies a bit of serial detective work, even if they don’t have a intercom to hand.

Yes. The system is expandable and up to 3 monitors (including the one in the kit) can be connected for each dwelling, along with 2 external entrance panels (including the one in the kit).If we cannot provide a quote from your specification we will be pleased to send a Surveyor down to your property at no cost, to prepare a report No, kit K40910 does not offer this possibility. For remote management from a smartphone you should opt for K40945. No, the number of cycles cannot be modified, but the volume and melody can be modified (among the 6 available for selection). Yes, simply perform the monitor self-start and the camera can be consulted from the monitor by following the consultation sequence (both in entrance panel call and in self-start), which is: -CAM1 (entrance panel camera 1)-CCTV1 (optional camera 1) -CAM2 (entrance panel camera 2)-CCTV2 (optional camera 2).The sequence of display of the entrance panel cameras or cameras outside the control is chosen on the monitor. This sequence cannot be modified so the first image shown remains the one from the entrance panel.

From any monitor it is possible to call and communicate with other monitors connected to the system in the same housing unit. Power for the system is present as a constant 24V DC, and the audio is still an old-fashioned analogue signal that we’ll all be familiar with. On that 24V DC though are imposed a series of pulse trains to trigger the different alarms and other functions, and he describes extracting these with an oscilloscope before showing us the circuitry he’s used to send and receive pulses with an Arduino. The bulk of the video is then devoted to the software on the Arduino, which you can also find in a GitHub repository. We are not responsible for Australia Post transit times as they do vary depending upon your destination. Ringtone volume and volume for communicating, brightness, colour and contrast are adjustable. Possibility of choosing between 6 melodies available for selection. ‘Mute’ functionThe monitor ringtone can also be turned off for a programmable time. A light indicates when the Do not disturb function is activated. The Vimar 46CAM.136B.8 camera can be connected to the CCTV and GND terminals of the outdoor station; Maximum length: 100 m with SYV75-3/RG59 cable. Depending on the distances to cover between the external entrance panel and the last internal video entryphone, you should identify the cross-section of the cable, specifically:
