About to invest in new CCTV cameras? If you want them to capture footage that’s crisp, clear, and useful, they’ll need to have the right level of resolution. At the most basic level, resolution refers to the level of detail the camera lens captures while recording.
Low resolution or ‘low res’ cameras tend to offer footage that’s either grainy or blurred, while high res systems provide a much more detailed insight into events captured on CCTV. With that said, the CCTV systems on the market today vary significantly in many aspects, and the resolution level is no exception.
Let’s take a look at the basics of CCTV camera resolution, then explore some of the best options available in Melbourne.
CCTV Resolution: A Brief Overview
When you’re looking at CCTV cameras, resolution is one of the first things to pay attention to. It basically determines how sharp and detailed your footage will be. A 4MP camera is a great starting point if you want clearer images than standard HD. It gives you better visibility of things like faces or licence plates without using up loads of storage. Step up to 6MP and you’ll notice a bump in detail, which is handy if you’re covering a larger area and want to maintain clarity.
If you’re chasing the best image quality, then 8MP or 4K cameras are where it’s at. They give you ultra-sharp footage that holds up even when you zoom in to see something specific. This kind of resolution is perfect for bigger properties, commercial spaces, or anywhere you might need to go back and review footage in serious detail.
Just keep in mind that higher resolution means bigger files, so you’ll need a system that can handle the extra data.

Explaining Resolution From a Scientific Perspective
In the context of security cameras, the term ‘resolution’ refers to the number of pixels in an image, typically measured in megapixels (MP), where one megapixel equals one million pixels. The higher the pixel count, the more information (or detail) the image is able to contain.
For example, a 4MP image (2560 x 1440 pixels) contains over 3.6 million pixels, while an 8MP or 4K image (3840 x 2160 pixels) has over 8.2 million. A higher pixel density allows for more precise rendering of fine details, such as facial features or text on a licence plate.
From a signal processing perspective, higher resolution cameras generate more data per frame. Therefore, they require greater bandwidth to enable the transmission and more storage for archiving. The clarity of captured footage also depends on sensor quality, lens optics, compression algorithms (like H.265 or H.264), and lighting conditions.
While resolution alone doesn’t determine overall image quality, it often plays a critical role in digital zoom performance. Lower resolution footage tends to pixelate or blur when zoomed, whereas high-resolution images retain clarity because of the denser pixel grid.
Product Overview by Brand
If resolution is high on your list of priorities, it’s always safe to go with the leading brands. For us, that means Dahua, Hikvision, TP-Link, and LA Vision. We’ve personally supplied and installed cameras from all these industry names, and stand by the quality of their products.

Understanding the Difference Between 4MP, 6MP and 8MP (4K) Resolution
Struggling to understand exactly what all these figures mean? If so, keep reading and we’ll break it all down for you in simple terms.
4 Megapixels (MP)
Resolution: Typically 2560 × 1440
Pros: Sharper than Full HD (1080p), a good balance between detail and storage use.
Use case: Ideal for small to medium property owners wanting to capture faces and vehicle plates.
Storage/Bandwidth: Lower requirements than 6MP or 8MP.
Explanation: A 4MP camera offers around 1.3 times the resolution of Full HD, which means you’ll get more clarity in details like facial features or small text, especially when zooming in digitally. However, it doesn’t overburden your storage system, making it a popular middle ground for those who want better visuals than 1080p but without the costs of 4K. It’s well-suited for homes, retail shops, and office entrances.
6 Megapixels (MP)
Resolution: Around 3072 × 2048
Pros: Offers finer details, better digital zoom, and improved identification over wider areas.
Use case: Useful in commercial setups where a precise review of security footage is needed.
Storage/Bandwidth: Medium-high; more than 4MP, less than 8MP.
Explanation: 6MP cameras are a sweet spot between image quality and system efficiency. They can cover wider scenes without losing important detail, which makes them ideal for warehouses, parking lots, or building lobbies. When you zoom in digitally, the footage remains clearer than with 4MP, which can make the difference in identifying faces or plates in forensic investigations. Storage use increases slightly, but it’s still manageable with most modern NVRs.
8 Megapixels (MP) / 4K Ultra HD
Resolution: 3840 × 2160 (true 4K)
Pros: Outstanding clarity, great for identifying faces or licence plates at a distance.
Use case: Large properties, public areas, or situations requiring detailed post-event analysis.
Storage/Bandwidth: Highest demand; requires powerful NVRs and more network bandwidth.
Explanation: 4K cameras capture incredibly crisp footage, allowing users to zoom in on footage post-event with minimal image degradation. This level of detail is crucial in environments like airports, city surveillance, or high-security facilities. However, the higher resolution means larger file sizes, requiring more robust network infrastructure, higher-capacity storage, and faster NVR processors. For users willing to invest in performance and future-proofing, 8MP is the top-tier choice.
