1. A device for electronic control and surveillance, comprising: an electronic access control (EAC) module, comprising a reader sensor that reads access request data, wherein the EAC module generates access control data in response to receiving the access request data, the access control data having an authorization result establishing whether to authorize passage through a portal between a first area and a second area; a surveillance device for continuously surveilling an observation area proximal to the portal at least prior to a detection of an entry through the portal and prior to access being granted or denied in response to a presentation of the access request data or in the absence of the access request data, the surveillance device generating surveillance data related to the continuous surveillance of the observation area, the surveillance data including data related to a presence of people, objects, or a combination thereof at least one of at the observation area proximate to the portal and passing through the portal, the surveillance device generating at least one of image data, video data, and audio data; an analytics module that compares a combination of the access request data, the surveillance data, and the access control data to determine whether the surveilled people, objects, or a combination thereof are authorized to pass through the portal; a housing proximate to the portal, wherein the EAC module and the analytics module are co-located in the housing proximate to the portal.
