CCTV Camera Installation Perth — Complete Buyer's Guide

CCTV camera systems have become standard in Perth homes and businesses. Prices have dropped, image quality has improved dramatically, and remote viewing via smartphone has made them genuinely practical. Here's everything you need to know before making a purchase or booking an installer.

IP Cameras vs Analogue

Modern CCTV systems use IP (internet protocol) cameras that transmit digital video over your home network. These offer superior resolution (1080p to 4K), easier remote access, and greater flexibility in placement compared to older analogue systems. If you're starting fresh or upgrading an old system, IP cameras are the right choice. Analogue cameras remain in use on existing systems but are not recommended for new installations.

Wired vs Wireless

Wired cameras (PoE — Power over Ethernet) provide the most reliable connection and image quality. The cable runs from each camera to a central recorder, providing both power and data through a single cable. Installation requires cable routing through walls and ceilings — this is the main practical consideration. Wireless cameras are easier to install but depend on Wi-Fi signal strength and are vulnerable to interference and battery management. For permanent Perth installations, wired PoE systems are preferred by professional installers.

Resolution

1080p (2MP) cameras provide clear, usable footage for most residential applications. 4K (8MP) cameras deliver significant detail improvement, particularly useful if you need to read number plates or identify faces at distance. The trade-off is larger file sizes and higher cost. For most Perth homes, a mix of 4MP cameras at entry points and 2MP for general coverage is practical and cost-effective.

Storage Options

Video footage is stored on a Network Video Recorder (NVR) for IP systems or Digital Video Recorder (DVR) for analogue. Modern NVRs store several weeks of continuous footage on internal hard drives. Cloud storage offers off-site backup but involves ongoing subscription costs. For Perth residential systems, a local NVR with 1–4TB storage and cloud backup for critical areas is a solid approach.

Camera Placement Tips

Cover all entry points: front door, garage, side gates, and rear sliding doors. Position cameras at 2.5–3 metres height for the best angle and to minimise tampering risk. Ensure the camera captures faces, not just the tops of heads. Use weatherproof cameras outdoors (IP66 rated minimum for Perth's conditions).

Privacy Law in Perth

Under WA privacy guidelines, you should avoid cameras angled to capture neighbours' private areas or public footpaths in ways that could constitute surveillance of third parties. Cameras covering your own property — driveway, garden, entry points — are generally unproblematic. If in doubt, discuss placement with your installer.
