Do you remember the pop star drama "You From the Stars" in previous years? I believe that in addition to the professor's boyfriend and Qian Song Yi's beauty and emotional drama that, the most intriguing is the use of keyless door locks on the two protagonists - home password and fingerprint identification access control system. This kind of seemingly high-tech, high-cost open door-to-door approach is actually not “people-friendly†as it was not imagined. The application of access control systems to the homes of ordinary people is not uncommon. On the contrary, the popularization of access control systems has become a general trend. So how do ordinary users who do not understand vulnerabilities and who do not understand the access control system to be installed in the home access control system are not pitted? Do not worry, pay attention to the following three points to help you not be a layman.
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 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 access controller and system software debugging
System debugging 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.
