Building Video Intercom System Application and Selection

In recent years, the building video intercom system has become an organic component of residential construction as part of building intelligence, and has played an active role in the security of residential quarters and has been recognized by users. However, due to the lack of detailed information and technical support from the manufacturers, the operation of some systems did not achieve the expected results, and even could not be used normally, which had a negative impact on the contractors and developers. In order to make the building video intercom system really play its role, this article will focus on the application of building video intercom system, I hope it can help you.

The video intercom system is a set of modern well-off residential service measures, providing two-way visual communication between visitors and residents, to achieve dual recognition of images and voice to increase safety and reliability, while saving a lot of time and improving work efficiency. More importantly, once the door start, infrared alarm detector, smoke exploration detector, gas alarm and other equipment installed in the home are connected to the security indoor unit of the video intercom system, the video intercom system will Upgraded to a security technology prevention network, it can communicate with the residential community property management center or community guards by wired or wireless communication, thereby playing the role of security protection against theft, disaster, gas leakage, etc. Protection. At the same time, it can also improve the overall management and service level of the residence and create a safe community living environment, so it has gradually become an indispensable supporting equipment for a well-off residence.

Building video intercom system, generally including video intercom and intelligent network alarm, can meet the different needs of different occasions such as single-family, villa, ordinary residence, high-rise building and socialized residential area.

Scheme design and description

In order to ensure that the installation of the project is standard, concise, easy to expand, and simple, the building video intercom system mostly uses an open bus structure; the fully flexible codec mode, the user extension terminal is isolated, ensuring the system can be stable and long-term * operation; user extension The simple installation method of the separation of the terminal block and the body facilitates the engineering installation, avoiding the appearance damage or losing the machine during the installation.

Single building intercom system

The system is suitable for high-rise and multi-story buildings that only require intercom and electronically controlled unlocking and do not require networking. It consists of door host, user extension, uninterruptible power supply and electric control lock. The bus structure is adopted, the main line is a three-core line, and the two-core non-polar line is connected to the user via the interlayer distributor. The bus-to-user extension uses a layered distributor to isolate and protect the bus, so that any extension failure or short-circuit of the extension line will not affect the normal operation of the system, greatly improving the reliability and stability of the system. The user's extension must be coded, and the extensions are interchangeable to facilitate after-sales service. The system also has direct call and digital options.

Network alarm intelligent system

The networked alarm intelligent system is composed of a management center, a community entrance host, a ladder host, a user extension, a floor distributor, and a user extension with various alarms. The system adopts a bus structure. The main line is a four-core line and a video line is added. The staircase host is a four-core line plus a video line through the layer distributor to the user extension.

This building networking system can be equipped with multiple community entrance hosts, and a four-wire cable (an additional video cable for the visual system) is connected to each building's converter with a bus ring structure.

According to the configuration, the system has many functions such as visual intercom, image monitoring, emergency alarm, automatic alarm, security patrol punching, IC card access control, etc., and can carry out intelligent comprehensive management of the community through the computer. Each building is provided with a staircase host machine (when there are multiple entrances and exits, multiple auxiliary staircase machines can be expanded). The staircase host machine is equipped with four large LED displays, which usually display the building number and unit number of the staircase. When the imitation guest calls the resident, the resident's house number is displayed. Each visit to the household management center is recorded.

The visual host adopts a low-illumination high-definition camera, with infrared compensation at night, so that the residents can clearly see the visitors' images at night.

In the community, each host can also play a patrol check function. Each host can also choose to be equipped with a contact IC card or a contactless IC card. Residents can use the IC card to open the electronically controlled door lock. The ladder host with the contactless IC card function can usually store thousands of units. A piece of IC card usage information, if necessary, read the information through the "one card" management module of the management center.

User extensions can be equipped with infrared anti-theft detectors, door magnetic switches, smoke detectors, fire detectors, emergency buttons, doorbells. There are three ways to dismantle and arm the user's extension burglar: the extension is equipped with a remote control, the IC card provided with the host of the ladder, and the password. The remote control can also be used as an emergency button for emergency help, no matter where in the room, users can get timely help. The emergency call will not interrupt the original call in the system.

The management center can accept information such as handling household alarms and management calls, security patrol punching cards, unit electrical control door abnormalities, open alarms, IC card access control systems of various levels, can record the latest 32 items of information, connect to the property management computer, and use property management software Record, query and print various information in real time. At the same time, in the visual system, the management center can be programmed to realize the cycle monitoring of each stairwell of the community when it is empty, and in principle has covered some functions of the community monitoring system.

In short, when users choose a building video intercom system, they should first determine their own functional requirements, and then choose a specific system. After determining the system you need, you should then find the manufacturer that produced the product. The user should have a detailed understanding of the manufacturer, do they have a technical defense production license? Has it passed the test of the public security department or the relevant state unit? Is the manufacturer's quality assurance system complete? Perfect after-sales service system? Technical support? And the successful demonstration projects. Especially the system engineering of the networked alarm type intelligent community should be chosen carefully. After the manufacturer is determined, the user should also conduct a horizontal comparison of the manufacturer's system, focusing on the consideration of system engineering installation, such as wiring, installation, commissioning and so on. It is worth mentioning that whether the user's extension is isolated should be an important factor for selection.

After the above brief introduction, I believe you can find a practical and feasible building video intercom system that suits you.
