4MP vs 5MP CCTV Camera: Which Resolution Is Better in India?

If you are buying a CCTV camera for your home, shop, office or business, you may have noticed that 4MP and 5MP CCTV cameras are among the most common choices.

At first glance, 5MP appears to be the obvious winner because it has more pixels. However, the difference is not as large as the numbers suggest. A good 4MP camera with a better sensor, lens and low-light performance can produce a more useful image than a poorly designed 5MP camera.

For most home and small-business installations, 4MP is the better value. Choose 5MP when you specifically need additional detail and the price difference is reasonable.

Both resolutions are available in modern IP and HD-over-coax CCTV cameras. For example, current 4MP IP cameras can use 2560 × 1440 resolution, while 5MP models commonly use approximately 2560 × 1920 resolution.

What Is a 4MP CCTV Camera?

A 4MP CCTV camera has an image sensor capable of producing approximately four million pixels in its image.

A common 4MP resolution is:

2560 × 1440 pixels

That produces approximately 3.69 million pixels, although manufacturers and the market commonly classify this camera category as 4MP.

Modern 4MP cameras are available with features such as:

• Infrared night vision
• Color night vision
• Wide Dynamic Range
• Human detection
• Vehicle detection
• Two-way audio
• PoE
• Local microSD storage
• H.265/H.265+ compression

For example, current 4MP network cameras can offer 2560 × 1440 resolution together with features such as H.265+ compression and human/vehicle detection.

What Is a 5MP CCTV Camera?

A 5MP CCTV camera provides approximately five million pixels of image information.

A common 5MP resolution is:

2560 × 1920 pixels

Some 5MP cameras use other aspect ratios or image formats, so the exact resolution should always be checked in the specifications.

Modern 5MP cameras can also include:

• IR night vision
• WDR
• AI detection
• Human and vehicle classification
• Audio
• MicroSD storage
• H.265/H.265+ compression
• PoE

For example, a current 5MP IP camera specification lists a maximum resolution of 2560 × 1920 and features such as H.265+ compression and WDR.

4MP vs 5MP: How Much More Resolution Does 5MP Have?

The difference is smaller than many buyers expect.

If you compare approximately 4 million pixels with 5 million pixels, 5MP provides about 25% more pixels.

However, that does not mean the image will look 25% sharper to your eyes.

Resolution is only one part of image quality.

For example, a camera’s image quality also depends on:

• Sensor size
• Sensor quality
• Lens quality
• Lens focal length
• Pixel size
• Low-light performance
• Image processing
• Bitrate
• Compression
• WDR
• Camera positioning

4MP vs 5MP: Resolution Comparison

Resolution Category	Typical Pixel Dimensions	Approximate Pixel Count
4MP	2560 × 1440	3.69 million
5MP	2560 × 1920	4.92 million

The exact resolution can vary by manufacturer and camera type.

Some 4MP cameras, for example, use 2688 × 1520 rather than 2560 × 1440.

This is why it is better to check the actual resolution in the camera specifications instead of relying only on the marketing label.

4MP vs 5MP: Image Quality

5MP has a resolution advantage.

If two cameras have similar sensors, lenses, image processing and lighting conditions, the 5MP camera can capture more image detail.

This can be useful when:

• You need to identify faces
• You need to read signs
• You want more detail in a wide scene
• You need additional detail for digital zoom
• You are monitoring a larger area

However, the difference can be relatively subtle when viewing the complete camera image on a phone.

The advantage becomes more noticeable when you crop or digitally zoom into part of the recorded image.

4MP vs 5MP: Digital Zoom

More pixels can provide more information when digitally cropping an image.

Suppose a person occupies only a small part of the camera frame.

A higher-resolution camera gives you more pixels with which to work when enlarging that region.

Therefore:

5MP → generally better digital cropping potential.

4MP → still very capable for normal surveillance.

However, digital zoom cannot create detail that was never captured.

If you need to identify a person at a long distance, camera placement and lens selection may be more important than simply moving from 4MP to 5MP.

4MP vs 5MP: Sensor Size Matters

This is one of the most important points when comparing CCTV cameras.

Do not assume that a 5MP camera will always produce a better image than a 4MP camera.

Consider two cameras:

• Camera A: 4MP with a large, high-quality sensor
• Camera B: 5MP with a smaller sensor and poor low-light performance

Camera A can produce the better image, particularly at night.

Current 4MP and 5MP models demonstrate that sensor size, aperture, lens and illumination specifications can vary substantially between cameras.

Therefore, never buy a CCTV camera based only on its megapixel rating.

4MP vs 5MP: Night Vision

Megapixel count does not directly determine night-vision performance.

A camera can have 5MP resolution but produce noisy nighttime footage if its sensor and lens are not well suited to low light.

When comparing night performance, check:

• Sensor size
• Aperture
• Minimum illumination
• IR illumination range
• Smart IR
• Low-light image processing
• White-light illumination

For example, current 4MP cameras are available with very low-light specifications and advanced illumination systems, demonstrating why resolution alone cannot predict nighttime image quality.

For more information, see CCTV Night Vision Explained.

4MP vs 5MP: Color Night Vision

Color night vision is another area where megapixels are not the deciding factor.

A 4MP camera with a large sensor, wide aperture and good illumination can produce better nighttime color footage than a poorly designed 5MP camera.

If nighttime identification is your priority, compare the actual low-light specifications rather than choosing 5MP automatically.

See CCTV Color Night Vision vs IR for a detailed comparison.

4MP vs 5MP: Storage Requirements

Higher resolution generally means more image data, although actual storage requirements depend on bitrate, compression, frame rate and recording settings.

Therefore, a 5MP system can require more storage than a comparable 4MP system.

For example, storage requirements increase when you combine:

• More cameras
• Higher resolution
• Higher frame rate
• Higher bitrate
• Continuous recording
• Longer retention periods

Modern compression technologies such as H.265/H.265+ can reduce bandwidth and storage requirements compared with less efficient compression settings. Current camera specifications show H.265+ support on both 4MP and 5MP models.

See How Much Storage Does CCTV Need? before choosing your hard-drive capacity.

4MP vs 5MP: Bandwidth Requirements

Higher-resolution cameras can require higher network bandwidth, although bitrate is ultimately what determines the amount of network traffic.

A 5MP camera configured at a higher bitrate can use more bandwidth than a 4MP camera.

This matters particularly for:

• Multiple IP cameras
• Wi-Fi CCTV systems
• PoE networks
• Large offices
• Factories
• Warehouses

If you are installing several high-resolution cameras, check the NVR’s total incoming bandwidth and the network’s capacity.

4MP vs 5MP: Frame Rate

Do not assume that a higher resolution automatically means a higher frame rate.

Some cameras may support different frame rates depending on the selected resolution.

For example, a 5MP HD-over-coax camera specification can support 5MP at a lower frame rate while supporting 4MP at a higher frame rate.

If you monitor fast-moving subjects, check the frame-rate specification at the resolution you actually intend to use.

4MP vs 5MP for Faces

If your objective is facial identification, 5MP can provide an advantage because more pixels are available for the face.

But camera placement is often more important.

A poorly positioned 5MP camera can be less useful than a properly positioned 4MP camera.

For facial identification, pay attention to:

• Distance from the subject
• Camera angle
• Lens focal length
• Lighting
• Face size within the frame
• Movement
• WDR performance

If the face occupies only a tiny portion of the image, increasing resolution alone may not solve the problem.

4MP vs 5MP for License Plates

5MP can be useful for capturing additional detail in license plates, but resolution alone does not guarantee readable plates.

License plate surveillance often requires:

• Correct camera angle
• Appropriate focal length
• Suitable shutter speed
• Controlled exposure
• Good illumination
• Correct mounting height
• Enough pixels on the plate

If license plate recognition is a primary objective, consider a camera specifically designed for that application rather than simply selecting the highest megapixel rating.

4MP vs 5MP for Home CCTV

4MP is usually enough for most homes.

A 4MP camera can provide excellent detail for:

• Front doors
• Back doors
• Driveways
• Living-room entrances
• Staircases
• Garages
• Side passages

Choose 5MP if:

• The price difference is small
• You want additional digital-crop detail
• You are monitoring a wider area
• You have sufficient storage
• Your NVR supports the required resolution

For a broader selection, see Best CCTV Cameras for Home in India.

4MP vs 5MP for Shops

Both resolutions are suitable for shops.

4MP is usually sufficient for:

• Cash counters
• Entrances
• Small retail spaces
• Interior aisles
• General monitoring

5MP becomes more attractive when you need additional detail across a larger shop floor.

4MP vs 5MP for Offices

For offices, 4MP is generally sufficient for general surveillance.

5MP can be useful for:

• Reception areas
• Entrance monitoring
• Large open offices
• Parking areas
• Higher-detail identification

However, choosing a better lens and positioning the camera correctly can provide a larger practical improvement than moving from 4MP to 5MP.

4MP vs 5MP for Outdoor CCTV

Outdoor surveillance introduces additional factors.

You should evaluate:

• Weather resistance
• Night illumination
• WDR
• Sunlight exposure
• Lens selection
• Mounting position
• IR reflection
• Low-light performance

A 5MP camera with poor WDR can perform worse in a bright entrance than a well-designed 4MP camera.

For outdoor installations, see Best Outdoor CCTV Cameras in India.

4MP vs 5MP: Lens Choice

The lens can be more important than the megapixel difference.

A wide-angle lens captures a larger scene but places fewer pixels on a distant subject.

A narrower lens can place more pixels on a particular area.

For example:

• Wide entrance → wider lens may be appropriate
• Long driveway → narrower lens may be better
• Cash counter → moderate field of view
• Long corridor → narrower field of view can be useful

Some professional cameras use motorized varifocal lenses to allow the installer to adjust the field of view. Current 5MP models are available with motorized 2.8–12mm varifocal lenses.

4MP vs 5MP: WDR

WDR, or Wide Dynamic Range, is important when a scene contains both very bright and dark areas.

Examples include:

• Doors with bright sunlight outside
• Building entrances
• Parking entrances
• Windows behind people
• Shop entrances

A 4MP camera with strong WDR can therefore outperform a 5MP camera with weak dynamic-range handling in difficult lighting.

4MP vs 5MP: AI Detection

AI features are not determined simply by resolution.

Both 4MP and 5MP cameras can be available with intelligent functions such as:

• Human detection
• Vehicle detection
• Intrusion detection
• Line crossing
• Face detection
• Motion classification

For example, current 4MP cameras are available with human and vehicle detection, while 5MP models can also offer advanced analytics depending on the product line.

Therefore, if AI detection is important, compare the actual analytics capabilities rather than choosing based on megapixels.

4MP vs 5MP: Night Vision Range

Night-vision range is determined primarily by the camera’s illumination system and scene conditions, not its megapixel count.

A 4MP camera can have a longer IR range than a 5MP camera.

For example, professional 4MP cameras are available with long-range IR systems.

Do not use the megapixel rating as a substitute for checking the actual night-vision specifications.

4MP vs 5MP: PoE Compatibility

Both 4MP and 5MP IP cameras can be available with PoE.

When building a new system, verify:

• PoE standard
• Camera power consumption
• NVR PoE port capacity
• Total PoE power budget
• Network bandwidth
• Camera resolution compatibility

If you are considering a PoE installation, see Best PoE CCTV Cameras in India.

4MP vs 5MP: DVR and NVR Compatibility

Both 4MP and 5MP cameras can be found in IP and HD-over-coax systems.

However, the recorder must support the camera’s resolution and signal type.

Before purchasing, check:

• Maximum recording resolution
• Maximum camera resolution
• Supported camera protocols
• Maximum frame rate
• Incoming bandwidth for NVRs
• Storage capacity

Buying a 5MP camera does not guarantee 5MP recording if the recorder cannot record at that resolution.

4MP vs 5MP: Storage Example

Consider two identical CCTV systems.

System	Resolution	Relative Data Requirement
System A	4MP	Lower
System B	5MP	Higher

The actual difference depends on the selected bitrate and compression.

If you want longer retention, 4MP may make it easier to achieve your target recording period with a given hard-drive capacity.

If you choose 5MP, consider increasing storage if necessary.

4MP vs 5MP: Price

5MP cameras are often priced higher than comparable 4MP cameras, although pricing varies considerably by brand and features.

The better question is not:

“Which camera has more megapixels?”

Instead ask:

“Does the additional resolution provide enough useful detail to justify the additional cost?”

For a small home where cameras are mounted close to the subjects, 4MP may provide all the detail you need.

For a large property where you need to crop distant subjects, 5MP may be worth the additional cost.

4MP vs 5MP: Which Is Better for Night Recording?

There is no universal winner.

If both cameras have similar sensor technology and lens quality, the 5MP model can provide additional detail.

But a well-designed 4MP camera with a larger sensor and better low-light performance can produce cleaner nighttime footage.

For night surveillance, compare the sensor and low-light specifications before comparing megapixels.

4MP vs 5MP: Which Is Better for Large Areas?

5MP can be useful for large areas because the additional pixels provide more image information.

However, simply increasing resolution is not enough.

For large areas, consider:

• Camera placement
• Lens focal length
• Mounting height
• Field of view
• Lighting
• Target distance

In some cases, adding another 4MP camera is better than replacing one 4MP camera with a 5MP model.

Should You Buy 4MP or 5MP CCTV?

Choose 4MP if:

• You want excellent value
• You are installing CCTV at home
• You want lower storage requirements
• You have several cameras
• You want good image quality without overspending
• Your camera locations are relatively close to the subjects

Choose 5MP if:

• You want additional image detail
• You frequently crop recorded footage
• You monitor larger areas
• The price difference is small
• Your NVR supports 5MP recording
• You have sufficient storage
• You need additional pixels for identification

4MP vs 5MP: Common Buying Mistakes

1. Choosing based only on megapixels

Higher resolution does not automatically mean better image quality.

2. Ignoring the lens

The wrong focal length can make a high-resolution camera ineffective for your intended viewing distance.

3. Ignoring nighttime performance

Many CCTV incidents occur at night, so low-light performance should be part of your buying decision.

4. Buying a camera the NVR cannot fully record

Check the recorder’s maximum supported resolution and recording capability.

5. Ignoring storage

Higher-resolution recording can increase storage requirements.

6. Installing too few cameras

One 5MP camera cannot necessarily replace two strategically positioned 4MP cameras.

7. Ignoring WDR

Entrances and other high-contrast scenes can require strong WDR regardless of resolution.

4MP vs 5MP: Best Choice for Different Applications

Application	Recommended Resolution	Why
Small home	4MP	Excellent balance of quality and cost
Large home	4MP or 5MP	Depends on viewing distance
Apartment	4MP	Usually sufficient
Small shop	4MP	Good general surveillance
Large shop	5MP	Additional detail can be useful
Office	4MP or 5MP	Depends on area and identification requirements
Warehouse	5MP	Useful for larger areas
Parking area	4MP or 5MP	Lens and night performance are critical
License plate monitoring	5MP or specialized camera	More detail can help, but lens and shutter are critical

4MP vs 5MP: Is 5MP Worth It?

5MP is worth it when the additional detail solves a real surveillance requirement.

If you are simply monitoring rooms, entrances and small outdoor areas, 4MP is often enough.

If you regularly need to crop footage, monitor larger spaces or capture additional detail at moderate distances, 5MP can be a worthwhile upgrade.

The difference becomes particularly attractive when a 5MP camera costs only slightly more than an otherwise comparable 4MP model.

Frequently Asked Questions

Is 5MP better than 4MP CCTV?

Does 5MP CCTV use more storage?

Usually, yes, if the camera is configured to record at a higher bitrate. Actual storage requirements depend on resolution, bitrate, compression, frame rate, recording schedule and the number of cameras.

Does 5MP CCTV use more bandwidth?

It can. Higher-resolution cameras may require higher bitrates, although the actual bandwidth requirement depends on the camera’s encoding settings.

Is 5MP better at night than 4MP?

Not necessarily. Night performance depends heavily on the sensor, lens, aperture, illumination and image processing. A high-quality 4MP camera can outperform a poor 5MP camera at night.

Is 4MP or 5MP better for faces?

5MP can provide additional pixels for facial detail, but correct camera placement, lens selection and lighting are equally important.

Is 5MP better for license plates?

It can provide additional image detail, but license-plate capture depends heavily on lens selection, camera angle, shutter speed, lighting and the number of pixels covering the plate.

Can a 4MP camera be better than a 5MP camera?

Yes. A 4MP camera with a better sensor, lens, WDR and low-light performance can produce more useful footage than a poorly designed 5MP camera.

Do I need a 5MP NVR for a 5MP camera?

You need a recorder that supports the camera’s resolution and recording mode. Always verify the NVR’s maximum supported camera and recording resolution before purchasing.

Is 4MP CCTV cheaper than 5MP?

Often, comparable 4MP cameras cost less, but prices vary by brand and features. The difference should be evaluated alongside sensor quality, lens, AI features and night performance.

Final Verdict: 4MP or 5MP CCTV?

For most buyers in India, 4MP is the sweet spot.

It provides enough resolution for most homes, apartments, shops and offices while generally requiring less storage and bandwidth than a comparable higher-resolution system.

Choose 5MP when you genuinely need additional detail. It is particularly useful for larger areas, digital cropping and situations where you want more pixels on the subject.

But do not make the mistake of assuming that every 5MP camera is better than every 4MP camera.

The better buying hierarchy is:

1. Choose the correct camera location.
2. Choose the correct lens and field of view.
3. Compare sensor and low-light performance.
4. Check WDR and night vision.
5. Check AI features if required.
6. Then compare 4MP vs 5MP resolution.

Best value for most homes → 4MP.

More detail for larger areas → 5MP.

Best overall image → depends on the complete camera, not just megapixels.
