When it comes to security cameras, one of the most important factors to consider is the resolution. After all, a higher resolution typically means a clearer and more detailed image. But with so many options available, it can be difficult to know which one to choose. Two popular resolutions for security cameras are 720P and 960H. But which one is better?
What is 720P Resolution?
720P, also known as HD Ready, is a high-definition resolution that provides a resolution of 1280×720 pixels. This translates to a total of 921,600 pixels. 720P is a progressive scan format, which means that the image is displayed in a single pass, rather than in interlaced lines like traditional TV signals. This results in a smoother and more detailed image.
720P is a popular resolution for security cameras because it provides a good balance between image quality and storage space. It’s high enough to capture detailed images of faces and license plates, but low enough to keep storage costs reasonable.
What is 960H Resolution?
960H, on the other hand, is a higher resolution than 720P, with a total of 976,000 pixels. It’s often referred to as “HD” or “High Definition” resolution. 960H is a CVBS ( Composite Video Baseband Signal) format, which means it’s an analog signal that’s transmitted through a coaxial cable.
960H is a popular resolution for security cameras because it provides an even higher level of detail than 720P. It’s often used in applications where high-quality video is critical, such as in law enforcement or high-security facilities.
Key Differences Between 720P and 960H
So what are the key differences between 720P and 960H? Let’s take a closer look:
Resolution
The most obvious difference between 720P and 960H is the resolution. 960H has a higher resolution than 720P, with a total of 976,000 pixels compared to 921,600 pixels. This means that 960H can capture more detailed images than 720P.
However, it’s worth noting that the difference in resolution may not be noticeable in all situations. For example, if the camera is capturing a scene with low lighting, the higher resolution of 960H may not make a significant difference.
Aspect Ratio
Another key difference between 720P and 960H is the aspect ratio. 720P has a widescreen aspect ratio of 16:9, while 960H has a 4:3 aspect ratio. This means that 720P can capture a wider field of view than 960H, making it better suited for applications where a wider angle of view is needed.
Signal Type
As mentioned earlier, 720P is a progressive scan format, while 960H is an analog signal that’s transmitted through a coaxial cable. This means that 960H is more prone to signal degradation over long distances, whereas 720P is less susceptible to interference.
Compatibility
Finally, 720P is a more widely supported resolution than 960H. Most modern security cameras and DVRs support 720P, while 960H is typically only supported by specialty cameras and DVRs.
When to Choose 720P
So when might you choose 720P over 960H? Here are a few scenarios:

Wide Angle of View
If you need to capture a wide field of view, 720P may be a better choice. The 16:9 aspect ratio of 720P makes it well-suited for applications where a wider angle of view is needed.
Budget-Friendly Option
Finally, 720P is often a more budget-friendly option than 960H. If you’re on a tight budget, 720P may be a more affordable option that still provides high-quality video.
When to Choose 960H
On the other hand, when might you choose 960H over 720P? Here are a few scenarios:
High-Security Applications
If you need the highest level of detail possible, 960H may be a better choice. This is often the case in high-security applications, such as law enforcement or government facilities.
Low-Light Conditions
If you’re capturing video in low-light conditions, 960H may be a better choice. The higher resolution of 960H can help to compensate for low light levels, resulting in clearer images.
Legacy System Compatibility
Finally, if you have an existing analog security system, 960H may be a better choice. This is because 960H is an analog signal that can be transmitted over coaxial cable, making it compatible with older systems.
Conclusion
So which is better – 720P or 960H? The answer depends on your specific needs and application. If you need a higher level of detail and are willing to pay a premium, 960H may be the better choice. However, if you’re on a budget or need a wider field of view, 720P may be the better option.
