The 1080p is in reference to one of the dimensions of the screen measurements. The standard measurement is considered High Definition TV with an aspect ratio of 16:9 with 1920 pixels by 1080p. That screen resolution ends up being around 2MP when converted.
4MP camera images are composed of twice the resolution as a 1080p ratio. That’s roughly 4 million pixels. These higher resolution cameras offer better quality. This higher quality helps to better identify security threats.
The most common screen ratio of 4MP is 2592×1520 pixels. The higher MP (million pixels) offers a higher video quality than the 2MP of the old HD ratio.
What is the difference between 720p and 1080p cameras?
There are two different levels of resolution when it comes to HD analog cameras. 1080p and 720 pixels. The major difference is that the 1080p cameras have double the resolution of the 720 that comes in around 1MP.
Due to the large difference in resolution, there is a noticeable difference in picture quality and performance. 1080p cameras can produce more explicit pictures and better functionality. They are making the higher quality camera a worthwhile investment.
Why do security cameras have bad quality?
Security cameras are responsible for saving the captured footage for an extended period of time, sometimes even years. Lower quality images take up less space.
The lower the resolution, the harder it is to enhance the image. While you are still able to still zoom into the lower quality images, it is harder to decipher any details. The images are generally distorted or pixellated.
Higher quality cameras such as those with 4MP compared to a 720-pixel screen can provide more details. Such as the numbers on a license plate or the wording on a t-shirt.

Is 1080p better than 4MP?
1080p is roughly about 2MP. Anything above 1080 is considered to be HD. 4MP is a more pixel-per-square-inch format and can offer higher quality. If you are looking for more storage space for your system, then this option might not be the best solution. When you have a camera with a higher resolution, such as the 4MP, your security system requires more space to store the data.
That means that if you are tight on space, 1080p would be a better fit for your camera needs, but if you can afford to upgrade, the 4MP or HD image would provide a more clear picture. 4MP would also allow for better zooming in or enhancing.
Is 1080p better than 5MP?
As technology advances, it has become the new standard to have 4K video footage. 5MP is referred to as Super HD with a resolution of 2560×1920 pixels. This provides a crisp image compared to 1080p.
Is 4MP enough for CCTV?
While there is a difference between 4MP and 4K security cameras, a 4MP camera captures just under four million pixels. While it’s not the highest quality, it is an excellent balance between the surveillance footage quality and how much storage it takes up.
There are many different reasons to have a security camera, and resolution is only one feature to consider when buying a system. If you cannot afford enough storage, you might consider cutting the quality of your resolution. All of those goals should be established before deciding on a system.

Which is a better IP camera or CCTV?
IP cameras have advanced recording features. They have a higher quality image resolution. An IP system is able to connect many cameras to the same network. Enabling one network to cover a larger area than some CCTV systems. IP systems also utilize a digital storage system that can hold more content than DVR systems.
Traditional CCTV relies on cables and recording equipment, such as DVR and coaxial cable connections. CCTV requires storage to hold the recorded footage. Due to its limitations of cable connections, it can damage its quality by attaching too many cameras to a single system.
What is the best resolution for CCTV?
CCTV is measured by horizontal and vertical pixel dimensions and can be restricted by the camera capabilities and the type of recorder you are utilizing for the CCTV surveillance. These systems rely on an analog video signal. The highest resolution that a CCTV system can capture and store is 704 x 480 pixels. This is referred to as D1 resolution.
How much space does a high-resolution picture take up?
The higher the quality of the recorded image, the more digital storage space you will need. That means there is a limited number of hours that can be saved to a hard drive.
For example, a 4MP image will take twice as much storage space as a 2MP image. 1080p takes up the same amount of space as a 2MP image, and 720 takes up half of that space, which means that the lower quality of 720p can record four times as long as a 4MP quality recording.
