Wire Connectors for CCTV UK 2026: IP68 Gel & Push-In

Getting Connector Type Right for CCTV Wiring

Get the splice wrong and it's rarely the camera that fails first — it's the joint, months later, once damp and thermal cycling have done their work. UK CCTV runs typically carry three distinct signal types — DC power, PoE data, and occasionally coax — and each demands a different connector, from tool-free lever blocks like the WAGO 221-413 for dry indoor splices to gel-filled IP68 joints for anything outdoors. This guide matches connector type to job, conductor size, and BS 7671's rules on accessible, protected connections, so your terminations outlast the install—whether you're wiring a permanent facility or a temporary CCTV setup for construction sites.

What actually matters when choosing wire connectors electrical

Four things decide whether a connector earns its place on the van: port count and configuration, conductor compatibility, reusability, and voltage/current rating. Everything else is preference.

Port configuration first. Match the connector to the actual splice, not the nearest one in the drawer. A single camera tail-to-tail joint needs no more than a 2 In 2 Out, like the SPL-2-2-CL at £0.22, while a PSU distribution point feeding several PIRs or a run of illuminators wants a multi-port block such as a 1 In 5 Out or 2 In 6 Out design like the SPL-2-6 Clear. For panel and rack builds with many branches, a 12x12 splicing terminal keeps a whole distribution board tidy instead of stacking several smaller blocks, or step up to the SPL-3-9-3 at £0.55 for a 3 in, 9 out branch point.

Conductor compatibility is non-negotiable. CCTV wiring mixes solid, stranded and flexible cores across camera tails, alarm cable and mains flex, so a lever connector rated for all three avoids the loose-contact failures that plague connectors sized for one conductor type only. Always check the specific listing for conductor compatibility before ordering, since this varies between colour variants and port configurations even within the same connector family.

**Reusability matters more on a working install than a one-off wiring job.

2-Port Lever Wire Connector SPL-2-6 Clear — best for splitting a single feed across a run of downlights or PIR heads

This lever connector splits two inputs across six outputs in one compact block — our pick whenever a lighting circuit or junction box needs to divide cleanly without a strip of individual wire nuts.

• 2-in, 6-out configuration — one connector replaces several smaller splices where a feed and a switch return both need distributing to multiple points.
• Tool-free lever mechanism — open, insert, close; no screwdriver, no crimping tool, and it's reusable if you get a wire wrong.
• Clear housing — lets you check conductor seating and strip length at a glance, which matters more on site than in a drawer.
• Check conductor compatibility on the listing — the related SPL-2-6 grey variant is rated for solid, stranded and flexible conductors, so confirm the spec against your cable type before you buy.

Where it doesn't fit: a straightforward single wire-to-wire joint doesn't need six outputs — our SPL-2-2-CL 2 in 2 out, priced at £0.22, is the leaner, cheaper choice there, and if you're distributing to nine points rather than six the SPL-3-9-3, at £0.55, has the extra ports built in. This one earns its place specifically at the "one feed, several fittings" stage of a lighting or CCTV power run.

Grey 3-in-9-out Lever Wire Connector | SPL-3-9-3 — best for splitting one supply into multiple runs

Reach for the SPL-3-9-3 when a CCTV or lighting circuit needs one spur feeding a bank of downstream devices from a shared source. A single feed splits to nine outputs in one flame-retardant, tool-free housing, priced at £0.55 — built for panels and junction boxes where a run has to fan out cleanly rather than daisy-chain through multiple smaller connectors.

• 3 input / 9 output terminals — genuinely useful where three feeds (e.g. line, neutral, earth or three parallel supplies) each need to split multiple ways from one point, rather than the more common single-input designs.
• Tool-free lever mechanism — open, insert, close; no crimping tool or terminal block screwdriver needed on site.
• Flame-retardant housing — sensible reassurance inside a packed junction box or camera enclosure where several connectors sit close together.
• Reusable — levers release cleanly for re-termination during fault-finding or a camera swap, unlike a crimped or twisted joint.

The trade-off: this is overkill for a simple two-wire splice — a SPL-2-2-CL 2 In 2 Out at £0.22 does that job for less. And it's still a mechanical splice, not a sealed one — for anything exposed to damp, you want a connector rated for that, not this. Check the listing for conductor compatibility before you buy, and always isolate the circuit before working.

Clear Lever Wire Connector 2 In 4 Out | Tool-Free Splicing — best for splitting a single feed into multiple runs

This connector splits one incoming pair of cores into four separate outgoing terminations without a crimp tool, cable nut, or a trip back to the van for tape. It's the transparent 2-in/4-out lever connector we reach for when a camera home-run needs to feed two or three downstream spurs off a single junction point.

• 2 in, 4 out configuration, so a single mains or low-voltage feed can be split cleanly to multiple onward runs from one connector body
• Tool-free lever mechanism — open, insert, close, no crimping or stripping precision required beyond baring the core
• Clear housing lets you check at a glance that every core is seated and gripped, useful when fault-finding a flickering PIR or camera feed months later
• Reusable design, so a wrongly-terminated run can be opened and redone rather than binned like a single-use crimp or twist connector
• Check the product listing for conductor compatibility (solid, stranded or flexible) before ordering, as this can vary between connector variants

Where it doesn't fit: for a straight one-in-one-out joint the smaller SPL-2-2-CL is more compact and cheaper for the job, and if you're feeding a bank of six or more downstream spurs from a single junction, the 2-Port Lever Wire Connector SPL-2-6 Clear gives more outputs from the same footprint. Keep any connector inside a proper enclosure per your normal practice, not left exposed in a void.

SPL-2-2-CL Lever Wire Connector | 2 In 2 Out — best for small CCTV terminations

The SPL-2-2-CL is our pick for a single camera tail-to-flex splice inside a back box or junction enclosure — it's one of the most compact and lowest-cost lever connectors we stock, and it's the one we reach for most. Two inputs, two outputs, tool-free operation, done in seconds.

• 2 In 2 Out configuration — sized for a single joint rather than a distribution point, so it doesn't waste space in a compact enclosure
• Tool-free lever locking — push the conductor in, close the lever, no crimping tool or screwdriver needed on site
• Transparent housing lets you confirm the copper is fully seated before you close the box up — useful when you're working blind in a ceiling void
• Solid and stranded conductor compatible, so it handles both T&E tails and stranded camera flex without swapping connector types
• Priced at £0.22 each — cheap enough to keep a handful in every van for one-off repairs or PIR/sensor splices

Where it doesn't fit: anything needing more than two outputs — a junction box feeding several downstream cameras is better served by the 2-Port Lever Wire Connector SPL-2-6 Clear (check the listing for conductor compatibility) or a grey multi-port block. It's also not rated or marketed as waterproof, so keep it inside a dry enclosure rather than an external gland box. For a straightforward two-wire splice, though, it's hard to beat on size and price.

Which one should you buy?

Pick by port count and job size: a 2-port clear connector for general splicing, a low-cost 2-in-2-out for single repairs, a high-port-count terminal for distribution boards, and a rated WAGO connector where a recognised 3-conductor spec matters.

For most CCTV and general electrical splicing jobs, the SPL-2-6 Clear 2-Port Lever Wire Connector is the best all-rounder: two inputs, six outputs, tool-free levers, and a transparent housing so you can visually confirm each conductor is seated before closing a back box or camera enclosure. Check the listing for conductor compatibility before ordering, since specs can vary slightly between the clear and grey variants in the range. It suits engineers running multiple PoE or mains spurs off one junction.

If you're working to a tight budget or only need a simple in-line joint, the SPL-2-2-CL at £0.22 is one of the lowest-cost sensible options in the range, suitable for solid and stranded conductors. It's fine for a single camera tail repair or extending a PIR feed, but not for a distribution point with several branches.

For distribution boards, lighting circuits and control panels carrying multiple final circuits, a higher-port-count connector such as a 12x12 splicing terminal is built for exactly that higher-port-count, multi-branch scenario rather than a one-off repair.
