Hikvision has developed a new video intercom system, called 2-Wire HD, designed as an innovative solution to rejuvenate older video intercom installations.
This 2-Wire HD system by Hikvision combines state-of-the-art features and technology with an analog installation. This is a major revolution, as it is possible to install high-resolution outdoor camera panels and large indoor touchscreen monitors while reusing the building's original 2-wire setup. It even offers the possibility to use a mobile application to receive calls, view the image, and open the door from anywhere. All this with a simple and quick installation and configuration.
Analog video intercoms are particularly known for their ease of installation: simply place the devices in their respective places, connect the existing cables, and assign addresses so that the call works correctly.
Although this installation simplicity saves time and costs, it also has a significant drawback: the absence of modern technological features. For example, these systems usually do not have a mobile application to receive calls or open the door remotely, the camera-equipped devices have poor resolution, and their configuration is not very intuitive.
This is why Hikvision, a manufacturer with extensive experience in video intercom systems, has developed the 2-Wire HD system, which brings together the best of analog systems and the best of the latest generation IP systems.
Advantages of the Hikvision HD 2-Wire Video Intercom System
Outdoor panels
These devices, unlike those in conventional analog systems, have a 2 Mpx FHD wide-angle camera. This results in exceptional high-resolution image quality with a wide viewing angle, allowing for more peripheral area visibility.
They are also equipped with infrared, so when it gets dark and the light dims, the image switches to IR mode for noise-free night vision.
In addition, they feature WDR (Wide Dynamic Range), which eliminates backlighting and allows the image to be seen more clearly in areas where light falls directly on the camera.
Moreover, the modular design allows the outdoor panels to be adapted to different shapes and solutions, making the installation much more versatile. This, combined with a wide variety of available modules, enables different call or access methods. For example, radio frequency card reader modules, EM 125 kHz or MF 13.56 MHz, can be used to allow residents to access their homes using key fobs.
Hikvision modules also include information modules, which help indicate different floors and call codes, and include installer information among others.
Indoor monitors
- These are color touch monitors with a 7" screen. This type of equipment makes it much easier, more convenient, and intuitive to use, while providing a clear and high-quality display of the images from the outdoor panel.
- They have buttons to hang up and answer calls, as well as to open the door. In conventional analog systems, it is not so common to find monitors in household equipment.
- They have a faulty cable detection function, which assesses the cable quality and indicates whether it should be replaced.
- They have a bell input, allowing the conventional doorbell button to be directly connected to the monitor.
- They include a microSD card slot, so you can store screenshots of the people who have called the video door phone.
Wiring and installation
Regarding wiring
The connection and communication of traditional analog video intercom systems is done through multi-wire cables, usually requiring 4 + N wires.
The usual wire cross-section for this type of system is 0.22 mm², which ensures perfect operation with the Hikvision system.
Regarding power supply
Another distinctive feature is that no additional power supply is needed on each floor.
Small distributors are equipped with status LEDs to indicate whether the wiring is in optimal condition.
Regarding the type of connection
The Hikvision system supports both series and star wiring between monitors and small distributors.
Configuration
To configure the equipment, simply assign the address using the rotary switches on the back of the panel.
The configuration is simple and intuitive compared to modern systems that require network knowledge.
Mobile application
The Hikvision 2-Wire HD system has a mobile application to receive calls and open the door remotely.
Conventional systems usually do not offer this, which highlights the difference of Hikvision.
In conclusion, the Hikvision 2-Wire HD system is the best and most complete alternative for upgrading old installations seeking new technologies and market demands.
