Door Entry Systems

Whatever the size of premises you have, domestic or commercial, it is a basic vital security requirement that you control who enters, where and when.  From simple audio intercom systems to video intercom for multiple tenancy buildings to an online PC based Access Control System across multiple sites, Sigma Engineered Solutions has the right system to meet your needs, budget and all compliant with DDA Regulations.


Door Entry Solutions

Door Entry Systems consist of at least one entry panel, by a locked entry point such as a door or gate.  The entry panel will have at least one button to call up a particular handset allowing for a two way conversation to take place.  Once satisfied of the person at the entry point, access is granted remotely by simply pushing a button at the handset that will release open the door.  Video Entry systems also allow for an image of the person at the entry point to be displayed on the handset.
