- Powered by Power Adapter: If not using PoE, connect the camera to a standard power adapter (not included) and then connect it to your router via an Ethernet cable for data transmission.
2. Physical Installation
Mount the camera in your desired location using the provided installation screws. Ensure the camera has a clear line of sight to the area you wish to monitor. The IP67 rating ensures durability for outdoor placement.
3. App Setup and Remote Access
For remote viewing and management, download the "Guard Live" app from your device's app store (available on Android and iOS). Follow the in-app instructions to add your camera to the application. This allows for free remote access to live view, playback, and message notifications.
