Alhua Security Perth: You're Looking for Dahua

If you've been searching for "Alhua CCTV", "Alhua intercom", or "Alhua alarm system" and coming up empty, you're not alone. Alhua isn't a security brand. It's a misspelling of Dahua — one of the world's largest manufacturers of CCTV cameras, video intercoms, and alarm systems. Here's why the confusion happens, what Dahua actually is, and how to get it professionally installed in Perth.

Why People Search for "Alhua" Instead of Dahua

The misspelling comes directly from the Dahua logo. In Dahua's wordmark, the lowercase "d" is stylised — it wraps around the "a" in a circular form that, at a quick glance, reads as an "l". The result is that many people read "Dahua" as "Alhua" the first time they encounter the brand, particularly if they've seen the name on equipment rather than the company's website.

It's an extremely common search. Security installers, facilities managers, and homeowners across Australia have all done the same Google search. If you're on this page, you've found your answer: the product you're looking for is made by Dahua Technology, and it is very much a real, widely stocked, professionally supported brand.

What Is Dahua? CCTV, Intercoms, Alarms and More

Dahua Technology is headquartered in Hangzhou, China, and listed on the Shenzhen Stock Exchange. It is one of the two largest security manufacturers in the world by revenue and unit volume, with products deployed in over 180 countries. Dahua makes far more than just cameras — their product range covers the full scope of a modern security system:

• IP dome and bullet cameras — fixed cameras for perimeter, entry points, car parks, and indoor use
• Full-colour cameras — use warm LEDs to capture colour footage in darkness (no grainy black-and-white infrared)
• 4K cameras — ultra-high resolution for large areas requiring digital zoom after the fact
• AI cameras — on-device detection for people, vehicles, faces, and licence plates
• PTZ cameras — motorised pan-tilt-zoom for active surveillance of large areas
• NVRs (network video recorders) — central storage and management for IP camera systems
• Video intercoms and doorbells — two-way audio and video entry systems for homes and commercial properties, managed via the DMSS app
• Alarm systems (Dahua ARC) — wireless alarm panels, door/window sensors, and motion detectors that integrate with Dahua cameras in the same app

Why Dahua Is a Strong Choice for Perth Properties

Full-Colour Night Vision

Dahua's Full-Colour technology uses F1.0 aperture lenses and warm LED lighting to capture colour video in near-total darkness — down to 0.001 lux. This is a meaningful advantage over standard infrared cameras, which produce greyscale footage that makes identification much harder. For Perth properties where after-dark footage is most likely to matter, colour night vision is worth having.

AI Motion Detection

Higher-tier Dahua cameras include on-device AI that classifies detected objects as people, vehicles, animals, or non-specific motion. This dramatically reduces false alert notifications — you get a push notification when a person enters your driveway, not every time a cat walks past. For Perth homes and businesses, this makes self-monitoring via the DMSS app genuinely practical.

4K Resolution

Dahua's 4K cameras provide enough resolution to digitally zoom in on recorded footage — useful for identifying faces, licence plates, or other details after an incident. Combined with H.265+ compression, 4K footage is stored efficiently without requiring disproportionate NVR storage.

Remote Access via DMSS App

The Dahua DMSS (and gDMSS for Android) mobile app provides remote live viewing, playback, and push alerts from any device. It connects directly to your NVR over your internet connection. Setup is straightforward when installed by a professional who configures the network correctly.

Dahua vs Hikvision: What's the Difference?

The other dominant brand in the same market segment is Hikvision — and the two are frequently compared. Both are strong products at similar price points. The practical differences for most Perth installations:

Both brands are supported by Great White Security. We'll recommend the right product for your specific application after a site assessment.
