IP vs analogue vs wireless CCTV
For most Sydney homes and businesses, wired IP cameras over PoE are the most reliable option for whole-property coverage, HD-over-coax analogue systems remain a sensible choice where existing coax cabling is already in place, and WiFi battery cameras suit one or two flexible spots rather than an entire property. The right answer depends on what you're covering and whether the cabling is already there, not on which technology sounds newest.
IP (PoE) cameras: the current default
IP cameras send a digital video signal, along with power, over a single Cat6 Ethernet cable back to a network video recorder (NVR) or, for smaller setups, directly to cloud storage. This is what most new installations use today because it supports higher resolutions, doesn't degrade over long cable runs the way analogue signal quality can, and integrates cleanly with phone apps for remote viewing without extra hardware. Hikvision, Dahua and Ubiquiti's UniFi Protect range are all IP systems, and the cabling - Cat6, run once - tends to be future-proof enough to handle a camera upgrade years later without rewiring the property.
The main downside of IP is that it typically costs a bit more upfront than an equivalent analogue setup, largely due to the network switch or PoE-enabled recorder needed to power the cameras, and it requires roughly the same cable-running effort as any wired system, which is to say more effort than clipping a battery camera to a wall.
HD-over-coax (HD-TVI, HD-CVI): still relevant in specific cases
HD-TVI and HD-CVI are analogue formats that send a high-definition signal over the same type of coaxial cable used by older CCTV and even old analogue TV antennas, recorded to a DVR rather than an NVR. The main reason this is still relevant in 2026 is upgrades: a property with existing coax cabling from an older CCTV system can often be upgraded to HD-TVI or HD-CVI cameras and a new DVR without rewiring the property, which can be a genuinely cheaper and faster option than ripping out coax and running new Cat6 everywhere.
Where there's no existing cabling at all, most installers will recommend going straight to IP rather than running new coax, since the cost of running cable is similar either way and IP offers more headroom for future camera upgrades and easier remote access. HD-over-coax systems can still deliver decent image quality - many current HD-TVI cameras support 4K - but they generally lag slightly behind equivalent IP cameras on low-light performance and smart features like vehicle or person detection.
WiFi battery cameras: Arlo, Eufy, Ring, Reolink Argus
WiFi battery cameras from brands like Arlo, Eufy, Ring and Reolink's Argus range are popular for their easy self-install - no cabling, no professional needed, just a mount and a WiFi connection - and they're a genuinely good fit for a single doorbell camera, a shed, or a rental property where you can't run permanent cabling. The trade-offs are real, though: battery life typically runs from a few weeks to a few months depending on activity and needs recharging or a solar panel, WiFi signal strength drops off with distance and through brick or concrete walls, and many of these brands charge an ongoing subscription for cloud storage of recorded clips beyond a short free trial.
For a property that needs six or eight cameras covering multiple angles, relying entirely on WiFi battery cameras usually becomes a maintenance burden - batteries needing attention on a roughly staggered schedule, and WiFi congestion affecting reliability at the exact moment you need footage most. This is the main reason professional installers steer away from an all-wireless approach for whole-property coverage and reserve WiFi cameras for a specific gap a wired camera can't easily reach, like a detached garage with no easy cable path.
Ubiquiti UniFi Protect: the prosumer IP option
Ubiquiti's UniFi Protect sits between basic consumer systems and full commercial-grade CCTV, aimed at people who want a system with proper wired cameras and centralised local recording but also want to manage it themselves afterwards without a complicated interface. Cameras like the G5 and G6 range connect over PoE to a UniFi Dream Machine or a dedicated UNVR recorder, with no ongoing subscription required for local storage and a single, well-regarded phone app for live and recorded viewing.
It costs more per camera than equivalent Hikvision or Dahua hardware, but for a homeowner or small business that wants an IP system without being tied to unfamiliar recorder software, it's a common recommendation, particularly for buyers who already have other Ubiquiti networking gear in the house.
When each option makes sense
Choose IP over PoE for a new installation with no existing cabling, where you want the highest resolution and easiest remote access, or where the property has multiple entry points that genuinely need whole-property coverage. Choose HD-over-coax when there's already usable coaxial cabling in the walls from a previous system and you want to avoid the cost and disruption of rewiring. Choose WiFi battery cameras for a single flexible spot, a rental where permanent cabling isn't an option, or as a supplement to a wired system rather than a replacement for it.
AVsion in Maroubra typically recommends wired IP systems, either Ubiquiti UniFi Protect or Hikvision depending on budget, for whole-property jobs, and will use a WiFi camera as a one-off addition for a spot like a rear shed where running cable isn't practical, rather than building an entire system around wireless cameras.

Frequently asked questions
What's the difference between IP and analogue CCTV?
IP cameras send digital video over a network cable (usually PoE Ethernet) to a recorder, while analogue cameras like HD-TVI or HD-CVI send an analogue signal over coaxial cable to a DVR. IP generally offers higher resolution and easier remote access; analogue can be cheaper to install where coax already exists.
Are WiFi cameras like Arlo or Ring good enough for full home security?
They're good for specific spots - a front door, a side gate - but battery life, WiFi range and per-camera subscription costs make them a harder fit for covering an entire property with many cameras. Most installers use wired PoE cameras for whole-property coverage and reserve WiFi cameras for one or two flexible extra spots.
What is Ubiquiti UniFi Protect and who is it for?
UniFi Protect is Ubiquiti's IP CCTV ecosystem, covering cameras, a recorder (like the UNVR) and often a Dream Machine router, popular with buyers who want a system they can manage themselves with a clean app and no ongoing camera subscription. It sits in the prosumer space between basic consumer cameras and full commercial systems.
Can I mix wired and wireless cameras in one system?
Yes, and it's common - a wired PoE system for permanent coverage points with one or two WiFi cameras added for a spot that's hard to run cable to, like a detached shed or a rear fence. The trade-off is that the WiFi cameras usually live in a separate app rather than the same recorder and interface as the wired ones.
Why do installers avoid wireless cameras for whole-property CCTV?
Reliability. Battery cameras need recharging or a solar panel, WiFi signal weakens at range and through brick walls, and a busy home network can cause dropouts, none of which apply to a wired PoE camera drawing continuous power over a dedicated cable.
What's the difference between IP and analogue CCTV?
IP cameras send digital video over a network cable (usually PoE Ethernet) to a recorder, while analogue cameras like HD-TVI or HD-CVI send an analogue signal over coaxial cable to a DVR.
