HD and IP CCTV Systems in Sydney for Optimal Security Solutions
HD vs IP CCTV Systems in Sydney – A Complete Guide to Choosing Between High-Definition and Internet Protocol Security Solutions for Homes and Businesses
Choosing between HD over coax and IP CCTV ultimately comes down to the picture quality, the cabling, and how you intend to use the footage.
SCES designs and installs both for apartments, strata and commercial buildings across Sydney, Central Coast and Wollongong.
If you need clear images, fast searching and clean links to access control and alarms, IP is usually the better fit.
If you have good coax cabling you want to reuse and a tight budget, HD over coax can still make sense.
Quick Answer
Quick insights to guide your CCTV upgrade or installation.
Choose IP
When you want higher resolution now or later, flexible storage, remote access and easy integration to other systems.
Choose HD over coax
When the existing coax is in good condition, you have a fixed camera count and you need a cost-effective refresh without recabling.
What Is the Difference?
Understanding the two main CCTV signal types and where each fits best.
HD over Coax
Sends video over existing coaxial cable to a digital video recorder (DVR). It is simple, cost-effective and suits many retrofit jobs.
IP CCTV
Sends digital video over your network to a network video recorder (NVR) or cloud. It is flexible, easier to scale and integrates well with access and alarms.
Comparison at a Glance
A quick side-by-side look at how HD over coax and IP CCTV differ across key aspects.
Image quality and upgrades
HD over coax
Solid 1080p to 4MP typical. Higher resolutions exist but are less flexible across brands.
IP CCTV
Wide choice from 1080p to 4K and beyond, with brand-agnostic upgrades later.
Cabling and power
HD over coax
Reuses coax, power is usually separate. Good for sites with clean coax runs.
IP CCTV
Single network cable with PoE where supported. Easier adds and moves.
Storage and search
HD over coax
Uses a digital video recorder. Search is fine, but analytics are more limited.
IP CCTV
Uses a network video recorder or cloud. Strong analytics and fast event jumps.
Integration
HD over coax
Basic event links possible, but options vary by recorder.
IP CCTV
Integrates with access control and alarms so door or alarm events jump to the right clip.
Scale and flexibility
HD over coax
Best when camera counts are fixed and cable routes are known.
IP CCTV
Scales well, supports mixed manufacturers and more camera choices.
Total cost
HD over coax
Often the cheapest way to refresh using existing cabling.
IP CCTV
Higher up-front, but pays off with features, search speed and upgrade paths.
When Each Makes Sense
Practical guidance to match your site, cabling and future plans.
When HD over coax makes sense
- You have reliable coax to all camera locations.
- You need a budget refresh without network changes.
- You are happy with today's views and do not plan to add many new cameras.
- You prefer simple plug-and-play upgrades without complex IP configurations.
When IP is the smarter choice
- You want clearer images for identification and evidence.
- You plan to link cameras to access control and alarms.
- You expect to add cameras, change positions or move to cloud storage.
- You want modern analytics in a video management system (VMS).
Upgrades and hybrid options
- Keep good coax where it saves money and run IP to new locations.
- Use encoder or balun options where appropriate.
- For IP, plan PoE switches sized to your final camera count and recording goals.
- For either path, we set user roles, strong passwords and audit logging.
How SCES Helps
- We survey the site, check cables and confirm what footage you need to capture.
- We design a clear camera layout with lenses and positions that match your goals.
