Detailed description of steps

Then it will be equipped with a building intercom door. The power box is generally installed on the inner wall of the anti-theft iron gate, which should not be too far away from the electric lock, generally within 8m. During normal operation, do not turn the power supply upside down or horizontally. Install the mainframe at the door. The door host is generally embedded in the embedded box of the security door or the wall host. The bottom of the main engine should not be higher than 1.5m from the ground, and the operation panel should face visitors for easy operation. The installation should be firm and reliable, and ensure the effective viewing angle range of the camera lens. When installing the outdoor intercom door host. In order to prevent rainwater from entering the room, the gap between the host computer and the wall should be blocked with glass glue. The installation height of the main engine is 1.5m above the ground. Indoor unit installation.

Installation should be firm and reliable, straight and not inclined. The bamboo processor of networked intercom system should be installed in the monitoring center or population duty room in the community, and the installation should be firm and reliable.

Finally, wiring the equipment of the building intercom door. Before wiring, check the insulation between wires and between wires and ground again for the laid cables, and terminate them according to the equipment wiring diagram only after they are qualified. When the intercom host connects cables with special connectors, the press-fit shall be firm and reliable, and the terminals shall be numbered according to the drawings. Building intercom doors and cable shields should be crimped to protect the ground wire, and the grounding resistance value should meet the design requirements.

Selection point

First, stability: the stability of building intercom is very important! The design of building intercom system must be reasonable: all kinds of isolation and protection measures must be in place, and the circuit design must be accurate and reasonable, including not only the reasonable design of components, but also the perfect and stable software design of the system! Secondly, the use of components, we must use brand-new electronic components, and put an end to the use of second-hand and unstable components! The quality of components is also very important! The stability of building intercom can be said as follows: 60% comes from the building intercom system itself; 30% comes from the choice of construction environment and construction supporting equipment; 10% comes from the use of building intercom electronic components!

Second, after-sales service: no product can guarantee 100% perfection! After-sales service is another key issue! Some manufacturers who use second-hand components or inferior products are unwilling to provide after-sales service for users, or delay or deny after-sales service. Such customers mainly rely on low prices to compete in the market! Therefore, we must find a production enterprise with integrity and technical strength to cooperate!

disadvantage?

Anti-interference ability: Anti-interference is a common headache in the building intercom industry. In terms of product quality, the anti-interference ability needs to be improved, especially in some thunderstorm-prone areas. In site construction, improper route selection and irregular wiring will also lead to various interference problems. Therefore, it needs to attract the general attention of product suppliers and construction parties.

Signal attenuation: Video amplifier is usually used to solve the problem, but it can also lead to distortion problems. However, if the conductor is not selected properly, signal attenuation will also occur.

Networking function: both bus and TCP/IP can be networked. Bus is still the mainstream, the networking function is relatively simple, and the transmission distance is limited, which is not conducive to large-scale networking.

Compatibility/standardization: The compatibility/standardization problem caused by the inconsistency of audio and video coding and decoding algorithms, wiring standards, communication protocols and interfaces has been puzzling buyers, and this part still needs the relevant departments to take the lead in promoting the formulation of relevant standards.
