 Choosing between 4MP, 6MP and 8MP? Learn how resolution affects clarity, storage and cost before your security camera installation. Honest CCTV installation Melbourne advice from Auztech Security.


How Many Megapixels Do You Need? 4MP vs 6MP vs 8MP Security Cameras Explained

Walk into any electronics shop and the biggest number on the box wins. But more megapixels isn't always better, and it isn't always worth the money. At Auztech Security, we explain this before every security camera installation so you pay for the clarity you actually need.

What Does Megapixel Mean?

A megapixel is a million pixels. More pixels give you a sharper image and let you zoom into a recording and still see detail, such as a face or a number plate. But resolution is only part of the picture.

4MP: The Everyday Choice

A 4MP camera gives a clear, reliable picture for most homes. It suits front doors, hallways and small yards, and it keeps storage and cost down. For many families, this is all the detail they need.

6MP: The Sweet Spot

A 6MP camera adds noticeably more detail at a sensible price. It works well for driveways, wider yards and entries where you want to identify people clearly. Many of our customers choose 6MP AcuSense packages for exactly this reason.

8MP (4K): Maximum Detail

An 8MP camera captures true 4K video. It's ideal for large properties, car parks, shopfronts and anywhere you need to zoom in on distant detail. The trade-off is a higher price and more storage.

Resolution Isn't Everything

Three things matter just as much:

  • Lens and sensor quality: a good 4MP camera can beat a cheap 8MP one
  • Night performance: clear footage after dark is what you need most
  • Placement: a camera in the wrong spot wastes its resolution

That is why the best CCTV installation near me starts with a site visit, not just a product list.

Think About Storage and Network

Higher resolution means bigger files. Your recorder needs enough hard drive space, and your cabling must carry the data. A well-planned CCTV installation Melbourne matches camera, recorder and storage so nothing is overloaded.

Mix and Match

You don't need the same camera everywhere. Many homes use 8MP on the driveway, 6MP at the front door and 4MP inside. A smart camera installation puts the detail where it counts.

Build a Complete System

Cameras are the eyes, but they work best with the rest of your protection. Adding alarm security and a professional home security system gives you detection, deterrence and proof. If you're still comparing options, our guide to the best home security systems is a good place to start.

The Best Home Security Camera System in 2026: An Installer’s Honest Comparison

Image
  The Best Home Security Camera System in 2026: An Installer’s Honest Comparison Every “best security camera” article you’ve read was written by someone who has never drilled a hole in a wall. They rank cameras by spec sheet. We install these systems in Melbourne homes every week, then get called back when something doesn’t work — which teaches you very different things about which cameras are actually good. This is a straight comparison of the four brands we install: Dahua , Hikvision , HiLook and Uniview . We stock all of them. We have no reason to push you toward one. First: The Thing Nobody Tells You The brand matters less than the install. A $2,000 camera system mounted at the wrong height, aimed at the wrong angle, with the recorder sitting in plain sight by the front door, is worse than an $800 system installed properly. The three things that actually determine whether your cameras identify an intruder: Height and angle. Cameras mounted too high see the top of a head. 2.5-3...
