Wireless Security Intercom

There are a few choices in wireless technology for a security intercom. The types available are two-way radio, full-duplex 900Mhz, WiFi, and cell phone network based intercoms as discussed below.

Two-way radio security intercoms (also called callboxes) use either VHF or UHF business band two-way radio frequencies. They typically require an FCC license, however we have callboxes in the MURS (multi-use radio service) frequencies that do not require a license. If you have existing radios we can also match the frequencies on those. These callboxes can have a range of up to a mile or cover multiple floors in a building. These callboxes are paired with either handheld or desktop base station intercoms.

The Full-Duplex 900Mhz intercom system can have a range of up to 4000 feet, but they are more sensitive to line of sight than the two-way radio callboxes. While the two-way radio intercoms are push-to-talk, release-to-listen, these operate more like a phone call with both parties being able to speak at the same time. These have noise cancellation and can be used in noisy environments, however for extremely noisy environments we have one that has an external horn speaker.

The WiFi intercoms require a WiFi signal at the gate or door. The best part of these is that they typically include video that can be accessed from an app on a smart phone or via a touch screen tablet.

A cell phone network intercom uses cell phone service just like a mobile phone. It has a phone number just like a cell phone. When a visitor arrives at the security point they press the call button and it then calls any phone number programmed into it. So no matter where you are you can talk to visitors at the gate. You can also use an app to send commands to the door or gate to unlock it or hold it open if your gate operator has that capability.
