Operating the NVR

Lorex Home Mobile App

The Lorex Home app allows remote viewing and control of your security system from a smartphone or tablet. To use:

• Download the free Lorex Home app from your device's app store.
• Create an account or log in.
• Scan the QR code displayed on your NVR (usually during initial setup or in the NVR's network settings) to add your system.
• Once added, you can view live footage, review recordings, and receive motion-activated push notifications and email alerts with screenshot attachments.

Smart Motion Detection

When paired with compatible Smart IP cameras, the NVR utilizes advanced person and vehicle detection. This feature minimizes false alarms by sending notifications only for relevant motion events. Use the Smart Search function to filter recorded footage by area, time/date, and specific detection types (person or vehicle).

Voice Control and Smart Home Integration

The NVR is compatible with Amazon Alexa, Google Assistant, Apple TV, and Chromecast. This allows for hands-free control and viewing of your security footage. Use simple voice commands to activate camera features or access live and recorded video directly on your smart TV or compatible smart display.

Maintenance
