The Reporter Wireless Intercoms use a 900 MHz digitally secure radio link between units, preventing eavesdroppers from listening to you conversations. Signal range is up to 1000 ft between stations, allowing placement in almost any location in your home or small business. Advanced digital circuitry allows these intercoms to be powered by 4 alkaline AA batteries (sold separately) for up to a year, or use the included AC adapters. Stations can be configured to operate on one of four available channels, and can be used in either push-to-talk mode or voice-activated monitor mode (with user selectable sensitivity).
