What is the design misconduct in building intercom?

A building intercom system project usually has many problems after completion. This is mainly due to poor engineering design and improper engineering. The main performances are as follows:

The design of the door intercom system of the building intercom system is installed in an open place, and the lack of necessary waterproof and moisture-proof treatment causes the equipment to enter the water and cause malfunction;

The door machine is designed on the door panel. When the door panel is opened and closed, the door machine will be vibrated to cause contact failure.

Install networked devices outdoors, causing failures in the absence of measures such as waterproofing and lightning protection;

Poor line construction, causing one household failure, the whole building system is shut down;

Cut corners and reduce the installed power and load, resulting in unstable power supply and image distortion and jitter;

Unstable operation caused by not using the original power supply;

Improper design of the door lock, resulting in door door failure caused by deformation of the door panel or poor quality of the electric lock.

The above-mentioned various faults, users and property management companies are unable to control, and ultimately the responsibility is attributed to the building intercom products and poor construction quality.

In addition, the construction process is rough (for example, the stainless steel screws are not used; the wiring is not welded; the insulated heat-shrinkable tube is not used; especially after the copper wires are twisted together, only the electric tape is used to wrap the grass), the wiring is loose. , broken wire or poor contact, spark interference and wiring oxidation hazards.

In addition, due to natural factors; equipment is not clean and maintenance, no routine inspection, natural failure caused by dust, insects, groin, rat urine. For example, some small insects climb into the floor platform, power supply, extension and mainframe during the winter. Because such equipment will generate tiny heat during work, it can warm the insects for the winter, causing short circuit of the circuit board and causing equipment failure.
