Main products: parking system , access control system , smart card , building control, attendance, patrolling, consumption, access to the access control system to do the following three major aspects of preventive measures:
First, prevent electromagnetic interference For readers, open the door button to pay special attention to anti-electromagnetic interference, especially lighting switches, electric typewriters and computers and other interference problems. If conditions permit, the reader should be installed at a distance of more than 30cm from the power source.
Second, to prevent the attenuation of the transmission signal The installation of the access controller must take into account the distance between the controller and the reader. The ideal transmission distance is within 100m. 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 debugging of the access controller and system software debugging system is the key to ensure the quality of the access control system. The emphasis is on the commissioning of the access 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.
