Using the RJ45 Cable Gland (Optional)

The Lorex 4K HD IP Dome Security Camera is a robust surveillance device designed for both indoor and outdoor use, offering high-resolution video capture and a range of features for reliable security monitoring.

Function Description:

This dome security camera captures video in 4K HD resolution, providing clear and detailed images for surveillance. It is primarily designed to connect to a Network Video Recorder (NVR) via an Ethernet cable, supporting Power over Ethernet (PoE) for simplified installation. The camera can also be connected to a local area network (LAN) via a router or switch. Its dome form factor allows for flexible angling of the camera lens, and its weather-resistant design, enhanced by an optional RJ45 cable gland, ensures durability in various environmental conditions. The camera incorporates an Auto Mechanical IR Cut Filter, which automatically switches between day and night viewing modes, indicated by an audible clicking sound, ensuring optimal image quality in different lighting.

Important Technical Specifications:

Resolution: 4K HD IP
Dimensions: 3.3" (83mm) diameter x 4" (101mm) height
Connectivity: Ethernet (RJ45)
Power: PoE (Power over Ethernet) or optional 12V DC power adapter (model#: CVA4902, not included)
Cable Type for Extension: CAT5e (or higher) Ethernet cable
Max Cable Run Distance (Extension): 300ft (92m) for up to 3 extensions (using RJ45 coupler or switch)
Environmental Rating: Rated for outdoor use, recommended for installation in a sheltered location. Not intended for submersion in water.
Compatibility: Compatible with select Lorex NVRs. A full list of compatible recorders is available on lorex.com/compatibility.

Usage Features:

Installation Flexibility: Can be mounted on walls or ceilings, with options for running cables through the wall/ceiling or along the surface using a cable notch in the base.
PoE Support: Simplifies installation by allowing both power and data transmission over a single Ethernet cable when connected to a PoE-enabled NVR or switch.
Optional DC Power: For connections to routers or switches that do not support PoE, a 12V DC power adapter can be used.
RJ45 Cable Gland: An included, pre-attached RJ45 cable gland provides weather resistance, protecting the Ethernet connector and plug from dust, dirt, and other environmental contaminants. For enhanced sealing in areas with regular precipitation, the cap can be sealed with silicone or electrical tape.
Night Vision: Automatically activates in low-light conditions. The camera's image sensor is highly sensitive to light, allowing it to remain in color mode even in low-light conditions. Users can adjust settings to force night mode if desired.
Cable Extension Options: Ethernet cable runs can be extended up to 300ft (92m) using CAT5e or higher Ethernet cables. For longer runs beyond 300ft, a switch is required. RJ45 couplers or switches (not included) can be used to connect male ends of Ethernet cables.
Audio Support: Compatible with Lorex HD NVRs that support audio. Users can ensure audio is enabled on the NVR and camera settings, and that the viewing device's volume is turned up.
Troubleshooting Guidance: The manual provides solutions for common issues such as no picture/signal, overly bright or dark images, night vision not working, unclear picture, bright spots in video at night, color in dark conditions, and no audio.

Maintenance Features:

Periodic Cleaning: The camera lens may require periodic cleaning. A damp cloth should be used, avoiding harsh, chemical-based cleaners. This helps maintain clear image quality and prevents issues like unclear pictures due to dirt, dust, or spiderwebs.
Environmental Protection: The RJ45 cable gland helps protect the Ethernet connection, reducing the need for frequent maintenance due to environmental exposure.
Pre-installation Testing: It is recommended to test the camera's functionality by temporarily connecting it to the NVR before selecting a permanent mounting location. This helps identify and resolve potential issues early in the installation process.
Secure Cabling: Ensuring that cabling is secure and not exposed or easily cut helps prevent damage and reduces the need for repairs.
Sheltered Installation: While rated for outdoor use, installing the camera in a sheltered location is recommended to prolong its lifespan and minimize exposure to extreme weather conditions.
