First, prevent electromagnetic interference
For readers and door openers, special attention must be paid to electromagnetic interference, especially for lighting switches, electric typewriters and computers. If conditions permit, the reader should be installed at a distance of more than 30cm from the power source.
Second, prevent transmission signal attenuation
The installation of the controller must take into account the distance between the controller and the reader. The ideal transmission distance is within 50m. For signal transmission cables, cable shielding and signal attenuation due to long-distance transmission must be taken into consideration. During the construction of the pipeline, the line pipe and cable tray made of steel should be used, and reliable grounding should be performed.
Third, the controller and system software debugging
System debugging is the key to ensure the quality of the access control system. The focus is on the commissioning of the controller and the operation of the system software. The commissioning of these two parts must be carried out by the manufacturer at the same time. The function of the controller is to set the relay linkage output function according to the need besides the card reader input, the time and location of the alarm generation and start-up such as camera, alarm horn and so on.
Although the access control in the community facilitates the safety of visitors to the majority of residents and the security of vehicles, the disadvantages follow.
If there is no visible end in the household access control, the visiting guests will impersonate the identity of another person, such as X classmates or friends, courier companies, etc., so that the homeowner will open the door without protection. Therefore, it is recommended that the community's contractors use the visual access intercom system as much as possible to improve the security of the residents' access control.
For the vehicle access control system, some car owners will carelessly place the IC-type access control card in the vehicle instead of carrying it. This causes the thieves to have the same car card. Therefore, it is recommended that the card be stored separately and stored with the card. To improve safety.
Although the access control system is convenient to use, if you have problems and you want to find a contractor to carry out repairs, most people will not find people because there is a huge profit in the current access control system. Although the real estate agent will not pay the access control contractors The money (usually 70% will be set aside for the maintenance costs), but the contractor would rather not have the balance and will not perform maintenance. Because the line layout of the access control system is conducted from the ground, once problems occur, it takes a lot of manpower and material resources to carry out line excavation and troubleshooting, which is quite troublesome.
