Product Description
The SPL-4 is a 4-port lever connector for terminating CCTV power and low-voltage wiring inside junction boxes and camera back boxes. It suits 12V DC and 24V DC distribution runs, so it fits most single-camera and small multi-camera power layouts fed from a centralised PSU.
Where it fits on a job
On a typical install, one SPL-4 sits at the camera end to split incoming power to the camera and a secondary device — an IR illuminator, alarm contact, or LED strip — without needing a separate junction strip. For larger sites with multiple drops from one power supply unit, installers commonly fit an SPL-4 at each back box rather than running individual home-run cables.
Termination and conductors
Termination is tool-free: open the lever, insert the conductor, close the lever. This suits engineers doing multiple terminations per enclosure where screw terminals or crimping would slow the job down. The connector accepts both solid and stranded copper conductors, so it works with typical CCTV power cable and alarm/control wiring on the same job without swapping connector types.

Frequently Asked Questions
What voltages does the SPL-4 support?
It's suitable for 12V DC and 24V DC power distribution, covering the common CCTV camera power ranges.
Can it take both solid and stranded cable?
Yes, the SPL-4 accepts both solid and stranded copper conductors.
Does it need any tools to terminate?
No — it uses a tool-free lever clamp, so conductors are inserted and secured by hand.
How many connections does one unit provide?
Each SPL-4 gives four independent ports for connecting conductors.
