CAMERA SYSTEM GUIDE

How to choose: HD or IP CCTV?

HD DVR and IP NVR CCTV systems both connected for mobile remote viewing

HD analogue + DVR/XVR

Connection: Camera → 3+1/coax cable → BNC video + DC power → DVR/XVR.

Power: A separate CCTV SMPS or adapter normally powers the cameras.

Mobile viewing: A network-ready DVR/XVR can connect to a router for live view and playback through its compatible mobile app.

Best when: Lower initial budget, familiar coax installation or an existing analogue cable can be reused.

IP camera + NVR

Connection: Camera → Cat6/RJ45 → PoE switch or PoE NVR → NVR.

Power: PoE can carry data and power on one network cable.

Mobile viewing: A network-connected NVR or compatible IP camera can provide live view and playback through its supported mobile app.

Best when: You want higher detail, easier expansion, network flexibility and richer smart features.

Mobile-view rule: Both HD DVR/XVR and IP NVR systems can support mobile viewing when the recorder is network-enabled, connected to the internet and configured with the compatible app. Mobile viewing is not exclusive to IP cameras.

Important: An NVR is not automatically a PoE NVR. When the NVR has no built-in PoE ports, a compatible external PoE switch is required. A video balun carries analogue HD video over Cat6; it does not convert an analogue camera into an IP camera.

ACCESSORY GUIDE

What each CCTV accessory does

Accessories are not random extras. Each one handles storage, power, cabling, internet access, mounting or local viewing.

CCTV accessories including HDD, PoE switch, router, monitor, connectors and camera boxes

Surveillance HDD

Stores recorded video. Capacity decides how many days of footage you can retain.

PoE switch

Powers and networks IP cameras. Port count and power budget must cover the selected cameras.

CCTV SMPS

Supplies 12V power to HD analogue cameras; capacity should match the camera count.

Cat6 cable + RJ45

Standard network connection for IP cameras. It can carry both data and PoE power.

3+1 cable + BNC/DC

Common HD analogue cable: coax video plus power. BNC carries video and DC carries power.

Video balun pair

Sends analogue HD video over a Cat6 pair. One transmitter/receiver pair is used per camera channel.

CCTV rack

Keeps the recorder, switches, router and power units organised, protected and serviceable.

4G/SIM router

Provides internet for remote viewing where broadband is unavailable; a separate data plan is required.

Monitor + HDMI

Shows live view and playback locally. HDMI connects the recorder output to the monitor or TV.

PVC camera box

Protects cable joints and connector termination near each camera; normally one box per camera.

UPS / surge protection

Keeps the system running briefly during power cuts and helps protect equipment from voltage changes.

Cable rule: IP cameras normally use Cat6 and RJ45. HD analogue cameras normally use 3+1/coax with BNC and DC. Video baluns are optional for analogue video over Cat6 and are compulsory only when that analogue-over-Cat6 design is used.
