CCTV Accessories

CCTV Accessories in South Africa

Cameras and recorders get the attention, and accessories are what determine whether an installation actually works. Power supplies, junction boxes, switches, brackets and adapters are the parts that fail, corrode or turn out to be missing halfway through a job. NeonSales stocks 175 CCTV accessories, from R30 for a kettle plug up to R1,950 for a Hikvision 8 port smart PoE switch.

What this collection covers

  • Power: 12V AC to DC adapters in 5A and 7.5A, multi-way PSU leads, kettle plugs, extension leads
  • Networking: PoE switches, RJ45 CAT5 and CAT6 extenders, network cable
  • Enclosures: junction boxes in several sizes, camera enclosures
  • Video distribution: HDMI splitters, VGA switches, HDMI cable
  • Mounting: monitor and TV brackets, swivel and pivot arms
  • Solar: panels for battery cameras

Sizing a power supply

Rule Why
Match voltage exactly Most cameras are 12V DC. Feeding the wrong voltage damages the camera immediately
Exceed the current draw A 7.5A supply happily runs a 2A camera. The reverse does not work
Add headroom for cable runs Long cable runs drop voltage, so a supply at the exact rating may under-deliver at the camera
Count every camera A multi-way PSU lead shares one supply across several cameras, so total draw is what matters

Junction boxes are not optional outdoors

Every cable join exposed to weather will corrode, and a corroded joint produces exactly the intermittent behaviour that gets blamed on the camera. Cameras that work fine for months then start dropping out at night or after rain are almost always a connection problem rather than a hardware failure. Use a junction box at every outdoor termination, and size it so the connectors sit comfortably rather than being forced in.

PoE or separate power?

Power over Ethernet sends power and data down one cable, which halves the cabling on IP installations and often makes an awkward camera position practical. It requires IP cameras and a PoE switch or a PoE-equipped NVR. Analogue and HDCVI cameras need a separate 12V supply alongside the coax, which is why multi-way PSU leads exist.

If you use a PoE switch, check the total power budget rather than the port count. Four ports does not mean four of any camera, since PTZ units with heaters and illuminators draw considerably more than a fixed bullet.

Common questions

What cable do I need? RG59 coax for analogue and hybrid systems, Cat6 for IP. Solid pure copper rather than copper-clad aluminium, since CCA causes voltage drop on long runs.

How far can I run a camera? Coax and Cat6 both have practical limits, and RJ45 extenders exist for pushing beyond them. Plan the run before buying the camera.

Do I need an HDMI splitter? Only if one recorder feeds several monitors. For a single display, a cable is enough.

Can I use any 12V adapter? Match the plug polarity as well as the voltage and current. Reversed polarity damages equipment.
