CCTV Guru stocks Australia’s best range of analogue HD security cameras, including Dahua HD-CVI fixed domes, motorised varifocal bullets, and PTZ cameras from 2MP to 5MP Starlight resolution. Transmit crystal-clear HD video over your existing RG59 or RG6 coaxial cable and transform your legacy system into a modern surveillance solution.
What Are Analogue HD Security Cameras?
Analogue HD cameras — including HD-CVI, HD-TVI, and AHD — are the modern evolution of traditional analogue CCTV. They transmit high-definition video (1080p up to 4K) over standard coaxial cable, making them the most cost-effective upgrade path for any site with existing coax infrastructure.
HD-CVI (High Definition Composite Video Interface) is Dahua’s proprietary analogue HD standard, supporting video, audio, PTZ control, and alarm signals over a single coax cable up to 500m. HD-TVI is a competing standard used by Hikvision and others with similar capabilities.
- Full HD (1080p), 4MP, and 5MP resolution over existing coax — no rewiring required
- Cable runs up to 500m on RG59 — far exceeding the 100m limit of IP cameras on Cat6
- Lower system cost than a full IP camera upgrade
- PTZ control, audio, and alarm signals over the same coax cable
- Compatible with HD-CVI/TVI DVRs and hybrid XVRs that also accept IP cameras
Why Choose Dahua HDCVI?
- Starlight Low-Light Performance — Sony Starvis-based sensors deliver full-colour or high-contrast monochrome images in near-darkness, outperforming standard analogue cameras in every lighting condition.
- Motorised Varifocal Lenses — Remote zoom and focus adjustment without physically accessing the camera — ideal for hard-to-reach mounting positions.
- IP67 Weatherproofing — Fully dust-tight and jet-water resistant for outdoor Australian conditions.
- IK10 Vandal Resistance — Impact-rated dome housings for high-risk or public-facing installations.
- Smart IR Night Vision — Adaptive IR illumination prevents overexposure at close range while maintaining visibility at distance.
- HDCVI 4.0 Protocol — Simultaneous video, audio, PTZ, and alarm data over a single coax cable.
- Hybrid DVR Compatible — Mix HDCVI cameras with IP cameras on a single Dahua XVR for a staged, budget-friendly upgrade.

Frequently Asked Questions
Only if your DVR supports HD-CVI. Standard analogue DVRs do not. You’ll need a Dahua XVR (hybrid DVR) or HD-CVI-compatible DVR to use these cameras.
Standard RG59 or RG6 coaxial cable — the same as traditional analogue CCTV. No rewiring required when upgrading from analogue.
Up to 500m on RG59 coax for 1080p, and up to 300m for 4MP/5MP — far exceeding the 100m Cat6 limit of IP cameras.
No. HD-CVI/TVI cameras require a DVR or hybrid XVR. They cannot connect directly to an IP NVR without a video encoder.
Both transmit HD over coax. HD-CVI is Dahua’s standard; HD-TVI is used by Hikvision and others. They are not cross-compatible — your cameras and DVR must match (or use a hybrid XVR that supports both).
