Hikvision has developed a new video intercom system called 2-Wire HD, presented as an innovative solution to modernize older video intercom installations.
This Hikvision 2-Wire HD system combines cutting-edge technology and features with an analog installation. This is a major revolution because by reusing the building's original 2-wire cabling, it's possible to install high-resolution, highly customizable exterior panels and large interior touchscreen monitors. It even offers the ability to use a mobile application to receive calls, view images, and open the door from anywhere - all with simple and quick installation and configuration.
Analog video intercoms are characterized primarily by their installation simplicity: just place the devices in their respective locations, connect the existing cables in the installation, and assign their addresses so calls can be made correctly.
While this installation simplicity saves time and costs, it also has a major drawback: the lack of current or notable technological features. For example, these systems typically don't have a mobile application to receive calls or open the door remotely, the camera-equipped devices have poor resolution, and their operation isn't very intuitive in terms of configuration.
For this reason, Hikvision - a manufacturer with extensive experience in video intercom systems - has developed the 2-Wire HD system that combines the best of analog systems with the best of the latest generation IP systems.
Benefits of the Hikvision 2-Wire HD Video Intercom System
Exterior Panels
Unlike conventional analog systems, these devices feature a 2MP FHD wide-angle camera. This provides exceptional high-resolution image quality with a wide viewing angle, allowing more peripheral areas to be observed.
They're also equipped with infrared, so when it gets dark and light dims, the image switches to IR mode for noise-free night vision.
Additionally, they feature WDR (Wide Dynamic Range), allowing you to eliminate backlight and see clearer images in situations or areas where light shines directly on the camera.
The modular design means exterior panels can be adapted to different shapes and solutions, making installation much more versatile. Combined with the wide variety of available modules, this enables different call or access methods. For example, RF card reader modules (either EM 125 kHz or MF 13.56 MHz) can be used to give neighbors access to their homes using key fobs.
Hikvision's modules also include information modules that display different floors and call codes, and contain installer information among other details.
Interior Monitors
- These are color touch monitors with a 7" screen. This type of equipment not only makes operation much easier, more convenient and more intuitive, but also provides clear, high-quality display of images from the exterior panel.
- They feature buttons for hanging up and answering calls, as well as opening the door. In conventional analog systems, screens aren't commonly found in the equipment installed in homes.
- They have a faulty cable detection function that assesses cable quality and indicates if replacement is needed.
- They feature a doorbell input, allowing conventional doorbell buttons to be wired directly to the monitor.
- They include a microSD card slot for saving screenshots of people who rang the video intercom.
Wiring and Installation
Regarding Wiring
The connection and communication of conventional analog video intercoms occurs through multi-core cables, requiring 4 + N wires. The usual cable cross-section for this type of system is 0.22 mm², which allows perfect operation with the Hikvision system.
Regarding Power Supply
Another distinguishing feature is that they don't require additional power supplies on each floor.
The small distributors feature status LEDs to indicate whether wiring is in optimal condition.
Regarding Connection Type
The Hikvision system supports both series and star connections between monitors and small distributors.
Configuration
To configure the equipment, simply assign addresses using the rotary switches on the back of each panel.
Configuration is simple and intuitive compared to modern systems requiring network knowledge.
Mobile Application
The Hikvision 2-Wire HD system includes a mobile app to receive calls and open doors remotely.
Conventional systems typically don't offer this, further highlighting Hikvision's differentiation.
In conclusion, the Hikvision 2-Wire HD system is the best and most complete alternative for rejuvenating old installations seeking new technologies and market requirements.
