Access control is great to ensure the security of your building. But is it really enough to have a key-card swiped and know who swiped it? That is where video surveillance integration for access control comes in.Video surveillance can be a support system for access control. When someone accesses a door, this can trigger a so-called event in the surveillance log. When properly integrated, upon clicking on the access event, the camera footage as well as the access credentials used will come up on the screen. No matter how large your organization is, you will have an image of who should be entering and who is actually entering. This can be driven as far as having an image sent to a specified email address or list, so every access event can be reviewed and authenticated the second it happens.
