• Long-Range Wireless Communication: The system uses a specific radio frequency band (like 410-490MHz) to transmit audio. The wireless voice doorbell can maintain a clear connection over distances up to 1000 meters (3280 feet) in open areas, or 20-50 meters through walls, eliminating the need for buried cables, offering flexible placement.
• Two-Way Full Duplex Audio: Both the outdoor and indoor wireless doorbell have a speaker and a microphone. This allows for natural, simultaneous conversation on the two way intercom doorbell, meaning both parties can talk and listen at the same time without needing to press a "talk" button, ensuring smooth communication.
• IP54 Water Proof Outdoor Unit: The intercoms wireless designed for outdoor mounting (by a gate or door) is rated IP54. This means the home security doorbell is protected against dust ingress and water splashes from any direction, making it suitable for installation in exposed outdoor locations, enhancing durability.
• Rechargeable Battery Powered: Both units contain built-in, rechargeable 2000mAh lithium batteries. The outdoor unit on the wireless intercom doorbells can last for several months on a single charge with typical use, while the indoor unit lasts about a week, and both charge via the included USB cable and dock, supporting cordless operation.
• Ideal for Gated Entries and Multi-Building Sites:​ The wireless intercom system is perfect for situations where a visitor needs to communicate with someone inside a building from a remote entry point. The long range intercom is commonly used at the entrance to a gated home, a hotel front desk to a room, a factory gatehouse.
