4-Inch LCD Video Intercom Monitor

The AIPTEK KB-3HRD is a surface-mount video intercom monitor with a 4-inch LCD display. It uses a handset for full-duplex communication with visitors at a connected door station. The unit is designed for residential or small commercial entry control. It requires a 24V DC power source to operate.

Upgrades from audio-only or smaller displays

Replacing an audio-only intercom adds visual verification before granting access. The 4-inch screen provides a clearer view than smaller panels without needing a large dedicated monitor. The jump is worth it when identifying visitors visually is a priority for security. Existing wiring must support the specified 2-conductor cable type.

Fits a surface or desk mount build

The monitor mounts directly to a wall or uses the MCW-S/A bracket for desk placement. It draws 410mA and 80mA from the 24V DC supply, so the PS-2410 power supply is required. Door release operates on 12V AC at 400mA. Wiring must use Aiphone #871802 cable for proper connection.
