Local storage provides convenient access to recorded footage without requiring the user to purchase a separate hard drive for initial setup.

Actual recording duration depends on:

Benefits include simplified installation, centralized connectivity and fewer separate camera power adapters.

The exact PoE power budget and individual port capabilities should be verified before installation.

Remote two-way talk functionality depends on the compatible mobile application, network connection and device configuration.
