Installation Guide
Before Installation
- Ensure the chosen mounting surface is structurally sound and capable of supporting the combined weight of the junction box and the camera.
- Verify that the PFA122 junction box is compatible with your specific Dahua camera model.
- Gather all required tools, including a drill, screwdriver, measuring tape, and a pencil for marking.
Mounting Steps
- Step 1: Mark Drilling Points. Carefully refer to the provided dimensional drawing for precise measurements. Use a pencil to accurately mark the locations for the four mounting screw holes on your installation surface.
- Step 2: Drill Holes. Drill pilot holes at the marked locations. If mounting on a wall, insert appropriate wall anchors as required for secure fastening.
- Step 3: Secure the Junction Box Base. Align the base of the junction box with the drilled holes and firmly attach it to the surface using the provided screws. Ensure the base is stable and securely mounted.
- Step 4: Cable Management. Route all necessary cables (e.g., power, video, data) through the designated cable entry points on the junction box. The design allows for either rear cable entry (through the mounting surface) or side cable entry (by removing a pre-punched blind stopper).
- Step 5: Connect Wiring. Perform all required electrical connections inside the junction box. Ensure that all connections are secure, properly insulated, and comply with local electrical codes.
- Step 6: Mount Camera. Attach your compatible Dahua camera to the junction box. Follow the specific mounting instructions provided with your camera. The junction box features standard mounting patterns for various Dahua camera models.
- Step 7: Close the Box. Securely fasten the junction box cover, ensuring that all seals and gaskets are correctly seated to maintain the enclosure's weather resistance.

Operation
The Dahua PFA122 is a passive mounting accessory. Its primary function is to provide a secure and weather-protected enclosure for camera wiring and connections. Once properly installed, no direct operational steps are required for the junction box itself. For operational instructions related to the surveillance system, please refer to the manual of your specific Dahua camera.
Maintenance
- Regular Inspection: Periodically inspect the junction box for any visible signs of physical damage, corrosion, or loose connections. Address any issues promptly to ensure continued protection.
- Cleaning: Clean the exterior surfaces of the junction box with a soft, damp cloth. Avoid using abrasive cleaners, harsh chemicals, or solvents, as these can damage the finish or seals.
- Seal Integrity: Ensure that all seals and gaskets remain intact and properly seated, especially for outdoor installations, to prevent water ingress and maintain environmental protection. Replace any damaged seals immediately.
- Fastener Check: Verify that all mounting screws and fasteners are tight and secure to maintain a stable and safe installation.
Troubleshooting
Common Issues and Solutions
| Issue | Possible Cause | Solution |
|---|---|---|
| Water inside the box | Improperly sealed cover or damaged gasket; unsealed cable entry points. | Re-seat the cover correctly, check and replace gaskets if damaged. Ensure all cable entries are properly sealed. |
| Loose camera attachment | Camera mounting screws not adequately tightened to the junction box. | Tighten all camera mounting screws securely to the junction box. |
| Junction box not secure | Loose wall mounting screws or inadequate wall anchors used. | Tighten wall mounting screws. If necessary, use stronger anchors or consider relocating the box to a more secure mounting surface. |
| Cable damage or malfunction | Cables pinched or improperly routed during installation. | Carefully inspect all cables for any signs of damage. Re-route cables to ensure they are not pinched or stressed. |
