5. Setup
5.1 Physical Installation
- Choose a Mounting Location: Select a suitable indoor or outdoor location. The camera supports wall mounting. Ensure the chosen location provides a clear field of view and is within reach of power and network connections. The camera dimensions are 6.3 x 6.3 x 10.63 inches.
- Prepare the Mounting Surface: Use the provided mounting template (if applicable) to mark drilling points. Drill pilot holes for the mounting screws.
- Secure the Camera: Attach the camera securely to the mounting surface using the provided screws and anchors. Ensure the camera is stable and properly oriented.
- Cable Management: Route the power and Ethernet cables. Use the waterproof connector kit for outdoor installations to protect connections from moisture.
5.2 Power and Network Connection
- Connect Power: Connect the camera to a suitable power source using the provided power adapter. The camera operates on corded electric power.
- Connect Network: Connect an Ethernet cable from the camera to your network switch or router. This camera uses an Ethernet connectivity protocol.
5.3 Initial Configuration
- Access the Camera: Use the ENS App or a compatible Digital Video Recorder (DVR) to discover and access the camera on your network. Refer to the ENS App or DVR manual for specific instructions on device discovery.
- Set Up Network Settings: Configure IP address, subnet mask, gateway, and DNS settings as required by your network.
- Change Default Password: For security, immediately change the default administrator password to a strong, unique password.
- Firmware Update: Check for and install any available firmware updates to ensure optimal performance and security.
6. Operation
6.1 Basic PTZ Control
The camera's Pan-Tilt-Zoom (PTZ) functions can be controlled remotely via the ENS App or a connected DVR/NVR interface. Use the directional controls to pan (horizontal movement) and tilt (vertical movement) the camera. Use the zoom controls to adjust the 25x optical zoom for wider or more detailed views.
6.2 Night Vision and Illumination
The camera features Starlight technology for enhanced low-light performance, providing color images in minimal ambient light. It also includes infrared (IR) illumination for complete darkness and built-in LEDs for full-time color illumination when needed. These modes can typically be configured for automatic switching based on ambient light conditions.
6.3 Smart Features
- Auto Tracking 3.0: Enable auto-tracking to allow the camera to automatically follow moving subjects within its field of view. Configure tracking sensitivity and duration in the camera settings.
- Perimeter Protection: Set up virtual tripwires or intrusion zones to detect unauthorized entry into specific areas. Alarms can be triggered upon detection.
- Face Detection: Configure the camera to detect human faces. This feature can be used for event triggering or recording specific incidents.
- Smart Motion Detection (SMD) 4.0: SMD 4.0 intelligently distinguishes between human and vehicle movements and other environmental factors (e.g., animals, leaves), significantly reducing false alarms. Adjust sensitivity and target types in the settings.
7. Maintenance
- Cleaning the Lens: Gently wipe the camera lens with a soft, clean, lint-free cloth. If necessary, use a mild lens cleaning solution. Avoid abrasive materials.
- Housing Cleaning: Clean the camera housing with a soft, damp cloth. Do not use harsh chemicals.
- Firmware Updates: Regularly check the manufacturer's website or the ENS App for firmware updates. Keeping the firmware updated ensures optimal performance, security, and access to new features.
- Cable Inspection: Periodically inspect all cables for signs of wear, damage, or corrosion, especially for outdoor installations.
