at present, the market entrance guard system controller category is various, the sham as the genuine, how to choose the right entrance guard controller?Believe that this is a difficult problem in front of many engineering contractor.Overall entrance guard controller selection are examined from the following aspects: system stability, operational and practical, cost-effective and so on.Let’s take a look at the specific factors of reference of choose and buy. title="nantong huanli"

a, entrance guard control to have crashed and self-check function

entrance guard system controller must have anti freezing function, in response to the controller crashes cause users unable to open or close the door, and cause inconvenience and losses, and prevent freezing function can greatly reduce the amount of maintenance engineering contractor and maintenance costs.Entrance guard controller must have reset function, both reset chip installation and using CPU with reset function, is a must.
the other entrance guard controller should have self-checking function, when the power supply shortage or other anomalies crash, system can be self-checking and start on his own.

2, have three levels of lightning protection function

entrance guard controller due to the distribution of the traffic line is, very susceptible to induction lightning struck by lightning and damaged.In order to prolong the service life and reduce losses, entrance guard controller must have lightning protection function, and the requirement is level 3 of the lightning protection design.Lightning protection index requirement for up to 4000 v, induction thunder for 50 times without damage to equipment, induction index is higher, the equipment of anti surge and antistatic ability is good.

third, be big enough storage

it is understood that the importance of data in the side, we want to highlight requirements, one is the registration card access to large storage capacity, demand about 20000 copies, offline storage record about 100000;Second is to prevent information loss, it is suggested that using nonvolatile memory chips such as Flash, the chip does not lead to meet power or impact on information loss.If USES is RAM + batteries, batteries or poor contact, may make the information lost to paralyze the entrance guard system.


4, control, friendly interface, simple operation and convenient

the application control program requires simple convenient, friendly interface.If too complicated, will increase the training time of project traders to users, increase the cost, and possibly users questioned by failed to grasp the operation of technical ability.Friendly user experience is also an important factor of access control system is good or bad.


ok, that’s entrance guard controller four discloser factors of choose and buy, want to help you, thank you for reading.
