Choosing the right CCTV camera for your property in Singapore is a key step in building a reliable security system. While factors like placement, storage, and budget all matter, camera resolution plays the biggest role in determining image clarity and overall effectiveness.
Resolution, measured in pixels and expressed in megapixels (MP), directly affects how much detail a CCTV camera can capture. Higher megapixels provide sharper images, clearer facial recognition, and better identification of people or objects—particularly in high-traffic or sensitive areas such as entrances, lobbies, and carparks.
In this guide, we’ll explain the most common CCTV camera resolutions in Singapore—1 MP, 2 MP, 4 MP, 5 MP CCTV camera, and 8 MP (4K Ultra HD)—and discuss how each option impacts image quality, storage requirements, and suitability for different types of homes and businesses.
What is Camera Resolution and Megapixels?
Resolution
Resolution is the number of tiny dots, called pixels, that make up an image. The more pixels there are, the sharper and clearer the picture looks. Think of it like a jigsaw puzzle—if you only have a few big pieces, the picture looks rough and blurry, but if you have thousands of small pieces, the picture looks detailed and realistic. In CCTV cameras, higher resolution means you can see finer details, like a person’s face or a car’s number plate, more clearly.
Megapixels (MP)
Megapixels (MP) tell you how many pixels an image is made of. One megapixel equals one million pixels. The higher the megapixel number, the more detail the camera can capture. For example, a 2 MP camera shows more clarity than a 1 MP camera, and an 8 MP (4K) camera can capture very fine details like facial features or license plates even from a distance.
The higher the megapixel count, the clearer and more detailed the footage. Let’s break down the different resolutions commonly used in Singapore’s CCTV systems.
CCTV Camera Resolutions Explained
1 MP CCTV Camera (720p Resolution)
A 1 MP CCTV camera is the most basic option, offering entry-level HD quality. It’s good enough to see what’s happening in an area but not detailed enough for things like identifying faces or reading number plates. Think of it as the “starter” level of CCTV—affordable and simple for general monitoring.
• Resolution: 1280×720 pixels
• Quality: Basic HD quality, sufficient for general surveillance but may struggle with fine details like facial recognition or number plates.
• Best For: HDB corridors, small shops, or areas with low security risks.
• Storage Needs: Generates about 500 MB to 1 GB of data per hour.
2 MP CCTV Camera (1080p Full HD)
A 2MP CCTV camera is the most commonly used option in Singapore today. It delivers clear Full HD footage, making it easier to recognise faces, spot movements, and capture small details compared to 1MP cameras. For many homeowners and businesses, 2MP strikes the right balance between image quality, storage needs, and cost.
• Resolution: 1920×1080 pixels
• Quality: One of the most common CCTV resolutions in Singapore. Provides clear images, good for identifying faces and small details.
• Best For: Homes, retail shops, and offices that need reliable everyday monitoring.
• Storage Needs: Requires around 1–2 GB of storage per hour; H.265 compression can cut this by up to 50%.
4 MP CCTV Camera (1440p Resolution)
A 4MP CCTV camera takes image clarity to the next level, offering noticeably sharper footage than 2MP models. This resolution is especially useful when monitoring medium-sized areas where you need to capture more detail, such as recognising faces from a distance or monitoring activity in larger spaces. It’s a popular choice for businesses and property managers who want higher clarity without jumping to 4K.
• Resolution: 2560×1440 pixels
• Quality: Sharper than 2 MP, with more detail for medium spaces.
• Best For: Carparks, condo common areas, and medium-sized businesses.
• Storage Needs: Around 2–3 GB per hour, with 4–6 Mbps bandwidth.
5 MP CCTV Camera (Super HD Resolution)
A 5MP CCTV camera offers sharper images than 2MP or 4MP models while still being more storage-friendly than 8MP (4K). This makes it the sweet spot for Singapore homeowners and business owners who want clear details like faces, license plates, and small movements—without the high costs of 4K setups. For most security needs, the 5MP CCTV camera strikes the right balance between clarity, affordability, and performance.
• Resolution: 2560×1920 pixels
• Quality: Crisp and highly detailed footage, ideal for identifying license plates or small objects.
• Best For: Warehouses, commercial buildings, and large outdoor areas.
• Storage Needs: Around 3–4 GB per hour, with 5–7 Mbps bandwidth.
8 MP CCTV Camera (Super HD Resolution)
An 8MP CCTV camera, also known as 4K Ultra HD, delivers the highest level of clarity available in today’s surveillance systems. With four times the sharpness of Full HD, these cameras capture extremely fine details, making them ideal for critical security zones where every detail matters. From crowded public spaces to large-scale facilities, 4K cameras ensure nothing goes unnoticed.
• Resolution: 3840×2160 pixels
• Quality: Top-of-the-line clarity, four times sharper than Full HD. Perfect for high-security zones and large-scale monitoring.
• Best For: Airports, MRT stations, stadiums, large commercial sites, or any environment requiring maximum detail.
• Storage Needs: Around 6–10 GB per hour, though H.265 compression can reduce this by up to 70%.

How to Choose the Right Resolution in Singapore
Selecting the right CCTV resolution isn’t about picking the highest megapixel camera available—it’s about finding the right balance between clarity, coverage, and cost. In Singapore, where property types range from HDB flats to large commercial facilities, your choice should fit both your environment and security goals. Consider these factors:

Budget
CCTV cameras come in different price ranges depending on their resolution. If you only need basic monitoring to see what’s happening, 1MP or 2MP cameras are affordable options. They give you clear enough footage for general use. If you want sharper images without overspending, 4MP or 5 MP CCTV camera are a good middle ground. For those who want the very best quality—like crystal-clear video in 4K—8MP cameras are considered premium, but they also come with higher costs.
Area Size
The size of the place you want to cover matters a lot. For a small indoor space like a room, office, or retail shop, a 2MP camera is usually enough. If you’re monitoring bigger spaces such as a condo lobby, warehouse, or carpark entrance, you’ll get better results with 4MP or 5 MP CCTV camera, as they capture more detail across wider areas. For very large spaces—like entire carparks, factory floors, or open outdoor areas—8MP cameras work best because they can cover more ground without losing clarity.
Purpose
Think about what you want to see on camera. If it’s just to keep an eye on movement and activity, a 2MP camera will do the job. But if you need to recognise faces, read license plates, or spot smaller details, you’ll need higher resolutions like 4MP, 5 MP CCTV Camera, or 8MP. The clearer the footage, the more useful it is when reviewing incidents.
Storage & Bandwidth
The higher the resolution, the more data your camera creates. This means you’ll need more storage space on your recording device (NVR or hard drive) and more bandwidth if you want to view the footage over the internet. For example, an 8MP camera produces much larger video files than a 2MP camera. If your storage or internet connection isn’t strong enough, the system may slow down or fail to keep recordings for long. That’s why it’s important to check if your NVR and network can handle the resolution you choose.

How Many Megapixels Do You Really Need?
The right camera resolution depends on where you’re installing the cameras and what level of detail you actually need. Here’s a clearer breakdown:
Homeowners (2 MP – 4 MP CCTV Camera):
For most homes in Singapore—whether it’s an HDB flat, condo, or landed property—2 MP or 4 MP cameras are usually more than enough. They provide clear footage to see who’s at the door, what’s happening in the living room, or if someone is loitering outside. A 2 MP camera gives good basic coverage, while 4 MP offers sharper images if you want to recognise faces or details more clearly.
Business Owners (5 MP CCTV Camera):
Shops, offices, warehouses, and F&B outlets often require more detail than homes. A 5 MP camera strikes a good balance between cost and quality. It allows business owners to monitor larger areas—like a retail floor or office lobby—while still being able to zoom in on important details such as cash counters, entrances, or customer interactions without the image becoming too blurry.
High-Security Areas (8 MP / 4K CCTV Camera):
Critical sites like banks, data centres, airports, MRT stations, or large carparks benefit most from 8 MP (4K Ultra HD) cameras. These cameras capture the finest details—like license plates at a distance, crowd behaviour, or even distinguishing individuals in busy areas. They’re designed for maximum clarity, which is crucial when security footage might be used for investigation or evidence.
Future-Proofing Your CCTV System
CCTV technology is improving every year, and what feels “high quality” today might look outdated in just a few years. While 1 MP and 2 MP cameras can still handle simple monitoring, going for higher resolutions like 4 MP, 5 MP CCTV Camera, or even 8 MP (4K) makes sure your system remains useful and reliable well into the future.
Think of it like buying a new phone—if you only choose the basic model, it may work fine now, but you’ll quickly feel its limits as apps and technology demand more. The same applies to CCTV.
A smart, practical approach is to mix different resolutions based on the importance of each area:
Higher MP cameras (4 MP, 5 MP CCTV Camera, 8 MP): Place these at key locations such as entrances, lobbies, cashier counters, and carpark gates—areas where you’ll need sharper images for identification and evidence.
Lower MP cameras (1 MP, 2 MP): Use these for general monitoring like hallways, storage areas, or wide spaces where extreme detail isn’t necessary. This saves both storage space and cost without compromising overall security.
By designing your CCTV system this way, you’re not only cutting costs but also ensuring that your system will still meet modern security standards years down the line.
