Ritron Call Box
Ritron call boxes are a combination intercom and 2-way radio in a waterproof outdoor housing. These Made-in-the-USA devices are the perfect way to implement two-way communication anywhere and save thousands of dollars in the trenching cost of wired systems. The callboxes use 2-way radio frequencies so they can be used to communicate over long distances.

The housing on the Q series call box is made of super-tough polycarbonate plastic so it too is very tough. This is a much smaller device so it doesn't require as much physical space. It is also lower cost and is our best seller.
Both devices are available in models that have built-in switches that can connect to a door or gate opener so you can remotely unlock a door or activate a gate. Some models also have the ability to broadcast pre-recorded voice messages.

Each call box is available in VHF, UHF, DMR digital, and license-free MURS frequencies. If you have existing two-way radios, you can give us your radio frequencies and we will program them to communicate with your radios.
At IntercomsOnline.com we specialize in the license-free MURS frequencies so you don't have to get an FCC license to operate your callbox. If you don't require activating a door or gate then we have low cost compatible MURS handheld and base station intercoms if you need to keep the cost as low as possible.
We have a 45-day trial period so you can test out a Ritron call box, and if it doesn't work in your application you can return it for a full refund.
