First Alert CX4AJBFD Product Description:


The First Alert CX4A Extended Junction Box (Part Number: CX4AJBFD) is a dedicated mounting accessory designed specifically for the CX4 fixed dome security camera. It provides a clean, protected space for wiring and connections behind the camera, helping installations look more professional while also reducing exposed cabling. This is especially helpful for surface-mount applications where you want a tidy finish and a more service-friendly setup.

By adding depth and structure at the mounting point, the CX4AJBFD supports more consistent cable routing and secure terminations, which can improve long-term reliability. It's a practical choice for both residential and commercial installs where durability and clean aesthetics matter, such as entryways, offices, retail interiors, covered outdoor areas, and other fixed-camera locations.

The CX4AJBFD is part of a complete CX4 accessory lineup built to maximize installation flexibility. Use wall mounts for optimal positioning, junction boxes like this one for clean, protected wiring, and pair with flush mounts or gangbox converter plates for streamlined, professional finishes on common electrical box formats. Together, these accessories help enable faster installs, improve durability, and expand mounting options across a variety of surfaces so your CX4 fixed dome cameras can be installed securely and cleanly almost anywhere.
