2019-01-11 10:35

There are anti-traffic Access Control system designed for some important places in the industry to prevent robberies. Therefore, it is recommended to prevent the trailing transformation by the following method:

access control system prevent trailing

1. Change the access control equipment:

Access control system can be installed with speed-pass door (three-roll gate). This method also has its shortcomings. It is basically used indoors, the width is only 55cm, only one person is allowed to pass, and there is a counting alarm function. If two people pass at the same time, an alarm will be generated. The three-roller brake can be used outdoors, but for those who cross from above, the preventive effect is not ideal, and the three-roller brakes are suitable for places such as security guards.

2. Install in and out of the card access control:

If a person follows the cardholder's entry, if you want to come out, you must also swipe the card to open the access door, in order to achieve the purpose of anti-tailing. However, when going out, if the trailing person also goes out with the cardholder at the same time, it can not achieve the purpose of true anti-tailing.

3. Two-way card reading plus double door interlocking this way

The double-door interlocking method can basically solve the trailing problem, because to open the second door, the first door must be locked, or the second door cannot be opened at all. There is also a more cumbersome method, which can be installed and used to detect portraits, but this method is cumbersome and requires a lot of knowledge extension.
