Audio and video intercom systems have become very popular as a cost-effective solution to gate and building entries as security has become a higher priority.
Hard wired, wireless and GSM options available to suit your needs.
Audio intercom systems allow you to speak to visitors via a call station at the entry, which is connected to an internal unit that houses a handset and control functions. Once confirming the visitor's identity, you can allow guests into the premises by releasing an electronic door strike that unlocks the door for a timed period.
Video intercom systems allow you to visually monitor an entrance as well as speak to visitors via a built-in camera linked to an internal unit that includes a monitor, handset and control functions. Again, you can release the door via the control panel timed unlock feature.
