What kind of function does this kind of product have? Trouble knowledgeable people to introduce me, thank you
Products are not the same function is not the same, the general price by the access control product cost + wire + installation costs + profit composition
Need to install a set of access control intercom, access control and intercom function, downstairs equipment with camera, upstairs can directly press the button to open the door, or credit card, or use the password to open the door, you can also set the remote control to open the door; Sets of equipment in about 3,000 yuan, but depends on the specific equipment of the brand to set; I wish you a happy life!
You are talking about the visual access control, but you said the secret control I do not know how you want to control, and can clearly point it?
