What’s the cost for a 5MP security camera system?

Take 5 minutes here to know what a 5MP security camera is, its advantages, potential problems, and the best budget consumer-level real 5MP IP cameras !

5MP Security Camera Definition

5MP (1920p) security cameras are super high definition cameras that record class-leading 5-megapixel images with enhanced camera sensors.

Typically, the 5MP CCTV camera has a high resolution of 3072 x 1728 or 2560 x1920, depending on the camera brands and types.

Every added pixel of the 5-megapixel cameras will improve the image clarity.

So the 5MP security camera is ideal to be used outdoors for clear recognition of human faces and plate number, or mounted in high positions for rich details of far-away objects.

1080p (2MP) vs. 3MP vs. 4MP vs. 5MP Security Cameras

Some of you might be using the analog cameras or the 1080p ones and consider for an upgrade.

Or you may simply want a high definition camera to record things clearly and think about the trendy 5MP CCTV cameras.

Is the 5MP security camera worth your investment?

The answer is an absolute YES. (Actually, the 5MP IP camera is highly affordable.)

A comparison chart shows the resolution  difference between 1080p, 3MP, 4MP and 5MP security cameras:

Security Camera Resolution Pixels Video samples (More>>)
Analog Security camera 720×480 0.4MP
720p HD Security Camera 1280*720 0.9MP
1080p Full HD Security Camera 1920*1080 2MP 2MP video
1440p Super HD Security Camera 2560*1440 4MP 4MP video
5MP Security Camera 2560*1920 5MP 5MP video

Note: The video samples you see with your own eyes may don’t show much difference between the 4MP and 5MP security cameras, yet the 5MP IP cameras will definitely have a better chance to help figure out the details when you are going to shot the distant objects like 30ft away.

Update, Nov 21st: We have also covered the image quality comparison among 4K, 1440p and 1080p cameras in a post. If you want to figure out the image quality differences, don't forget to check it out here>>

Image Quality Comparison

What Defines a Real 5MP IP Camera

A real 5MP security camera should record better images in both clarity and image quality in the aesthetic sense:

#1. Better Clarity

The 5MP security cameras have better clarity than the low megapixel cameras, thanks to their improved resolution. For example, the 5MP IP camera is sure to be at least twice clearer than the 2MP (1080p) ones.

#2. Better Image Quality

Not all 5MP security cameras offer 5MP quality images, and a REAL 5MP IP camera not only has better clarity but also better color purity and balance in the aesthetic sense.

The 5MP security camera image sensor and its lens play the trick.

Some 5MP security cameras improved their resolution without upgrading the sensor and matching lens, resulting in the “rubbish resolution” as some OPs complained in the CCTV forums.

Generally speaking, the 5MP IP camera should have a larger image sensor and better lens in order to produce real 5MP pictures, in both clarity and color performance.

That's why Reolink 5MP security cameras upgraded its image sensor to 1/2.9’’ larger size and matching lens to guarantee real 5MP high-quality images.

Why Buy a 5MP Security Camera

Maybe you have heard of some exciting benefits of megapixel security cameras.

The 5MP security cameras carry them all in a surpassing way, and here are the top 3 reasons you should buy a 5MP CCTV camera.

5MP Security Camera Captures Much Clearer Images

Some of you may take the 5MP security camera as overkill.

I can’t agree when it comes to home security.

You know the human face and license plate recognition requires extremely high resolution and a good angle to catch them. And 5MP security cameras provide you the best possibility to get what you need.

If your house was unfortunately suffered from burglars, break-ins or thefts, isn’t it just a pity that the camera footage is useless? What’s the point of having a security camera if it tells you nothing?

Moreover, the 5MP security camera has already become a consumer type camera these days, with an attractive price tag(Check the best budget picks).

Note: Generally, you’ll need at least 1080p resolution to identify the plate number and people day and night, and the better resolution, the better clarity. Well, some higher megapixels security cameras, like 10MP IP cameras, are usually used on specialized occasions, a real overkill for home use.

5MP Security Camera Has Flexibility in Placement

Thanks to the super clear images, 5MP security cameras fear nothing about the distance challenge for their image quality.

Some of you could mistakenly install the security cameras in high positions in order to cover a larger monitoring area. But finally end up with a useless blurry view.

With 5MP security cameras, you are free to place it on high positions, like the second-floor level, to have it look down on the 150ft driveway or even the whole lack areas without any worry about the blurry resolution.

Better still, if the 5MP IP camera is PTZ enabled, like the WiFi security camera Reolink RLC-523WA, there will be literally NO blind spots around.

5MP Security Camera Can Zoom in for Details

Higher megapixels allow you to zoom in for rich details, even under digital zoom.

Digital zoom is criticized by some as a fake function which will result in blurry images.

But 5MP security cameras can be digitally zoomed in to some extent. In fact, if you digitally zoom in a 5MP image, you will find it still clearer than the 2MP (1080p) cameras (under 2X zooming).

Extra tip: If you want better zooming capability, it’s advised to get a 5MP security camera with optical zoom function, like the Reolink RLC-511WA, with which the images will still be perfectly clear without quality degraded and destroyed.

5MP Security Camera Common Problems & Fixes

5MP security cameras could also cause some concerns, and on the top of the list are the bandwidth and the stream limit issues.

No worries. Here are some easy fixes.

#1. 5MP CCTV Camera Bandwidth Problem

"5MP security cameras are really bandwidth hogs."

The best solution to solve the problem is to get a reputable 5MP security camera with advanced configurations to fit it into any network conditions!

Take Reolink 5 megapixel CCTV cameras as an example:

You can switch between different recording modes according to your home bandwidth. The Clear mode delivers 5MP live streams for best clarity and consumes more bandwidth, and the Balanced mode will record in 1080p lower resolution and saves bandwidth.

#2. Stream Limit Problem

"It has exceeded the bit stream limit, please close channel 9."

Some 5MP security camera users may be troubled by the high resolution “burden”.

In that case, try to lower the FPS settings.

Generally, 15 FPS (or greater) makes a fluent 5MP security camera video, and that can be easily realized for common home networks even if you are using the 8 or 16 channel 5MP security camera system.

Extra tip: There is a simple IP camera bandwidth calculation to see how much bandwidth your 5MP security camera exactly consumes.
