Quick Fix Checklist (Start Here)
- Compatibility: Confirm that the junction box is compatible with your Lorex fixed camera at lorex.com/compatibility.
- Load capacity: The total installed weight must not exceed 6.61 lb / 3 kg.
- Surface strength: Confirm that the mounting surface can support the total weight of the junction box, camera, cabling, and any additional accessories.
- Hardware: Check that all included caps, screws, expansion plugs, stoppers, rubber stoppers, and required tools are available before installation.
- Cable routing: Plan cable routing before fastening the junction box to the wall or mounting surface.
- Fit: Do not force the camera onto the junction box. If the mounting holes do not line up, confirm compatibility before continuing.
- Environment: Inspect the installation location for moisture, chemical exposure, salt air, vibration, or other conditions that may affect long-term mounting strength.
- Final check: After installation, confirm that all fasteners are tightened and the junction box and attached camera are secure.
Junction box does not fit the camera or accessory
- Confirm that you are using the correct product: Junction Box for Fixed Cameras (JB301).
- Check compatibility at lorex.com/compatibility before installation.
- Make sure the camera is listed as compatible with the junction box.
- Confirm that the correct mounting holes and hardware are being used for your camera.
- Do not drill, modify, bend, alter, or force the junction box to fit an incompatible camera.
- If the camera does not fit, stop installation and confirm the correct accessory or mounting option for your camera model.
Mounting holes do not line up
- Make sure the junction box is positioned in the correct orientation before securing it to the surface.
- Confirm that the correct compatible fixed camera is being attached to the junction box.
- Check that the mounting surface is flat enough for the junction box to sit securely.
- Loosely position all screws first, then tighten them evenly after alignment is confirmed.
- If the holes still do not align, stop installation and recheck product compatibility.
Junction box feels loose after installation
- Confirm that all screws, bolts, washers, and nuts are securely tightened where applicable.
- Check that the correct included hardware was used where applicable.
- Make sure the mounting surface is structurally sound and strong enough to support the installed equipment.
- If installing into masonry, brick, concrete, wood, or another surface type, use fasteners appropriate for that material.
- Do not install the junction box on weak, damaged, unstable, or unsuitable surfaces.
- Remove the camera and reinstall the junction box if movement remains after tightening.
Camera or accessory feels too heavy for the junction box
- The junction box supports a maximum load of 6.61 lb / 3 kg.
- Confirm the combined weight of the camera, cabling, and any attached accessories.
- Do not exceed the maximum load capacity.
- Make sure the wall, mounting surface, or attached accessory can support the total installed weight.
- If the installed product feels unstable, remove it immediately and verify compatibility, surface strength, and fastener installation.
Installation surface is uneven or not secure
- Install the junction box only on a structurally sound surface that can support the total installed weight.
- Avoid installing on loose siding, damaged masonry, thin panels, or other surfaces that may shift or weaken over time.
- Use fasteners suitable for the surface material.
- If the wall or mounting surface is uneven, cracked, or not structurally sound, choose another installation location.
- For commercial installations, consult a qualified installer if surface strength is uncertain.
Cable routing is difficult
- Plan the cable route before fastening the junction box to the mounting surface.
- Make sure cables are not pinched, sharply bent, or pulled too tightly during installation.
- Confirm that cable openings and routing paths are aligned with the camera and installation location.
- Use the included caps, stoppers, rubber stoppers, plugs, or gland where applicable to help manage cable openings.
- Leave enough service loop for future maintenance where possible.
- Protect exposed cables from moisture, abrasion, and physical damage.
Rust, corrosion, or wear is visible
- Inspect the junction box regularly, especially in harsh environments.
- Installations near salt water, chemical plants, industrial areas, or high-humidity environments may require more frequent inspection.
- Check for loose fasteners, corrosion, cracking, deformation, water intrusion, or other signs of wear.
- Do not install or use the junction box if it is bent, cracked, corroded, loose, or otherwise damaged.
- Replace the junction box or hardware if strength or stability appears compromised.
- Do not continue using the junction box if the camera is no longer securely supported.
