These Ethernet IP based video door phone intercoms connect to your network, allowing the user to answer the door from one or more inside network station, or an iPhone or Android phone. Answer the door even when away from the home or work. Some IP video intercoms, also known as video doorbells, can integrate with NVR recorders for security video recording and play back. Start your IP video intercom with a front door station, and at least one indoor monitor station. For NVR integration please reach out to our support department to confirm compatibility.
