How Does Hd Camera 1080p Work?

19 Mar.,2024

 

Too busy to read? Here’s a summary:

  • If your camera is overseeing extensive spaces or capturing high-resolution images for the purpose of identification, a 1080p camera is probably necessary to meet your needs.
  • If your primary concern is basic monitoring and capturing minute details isn't necessary, a 720p camera would likely be adequate to meet your needs.

Advancements in technology over the past decade have led to significant improvements in the field of security cameras. We now have access to high-definition (HD) cameras capable of delivering detailed and clear footage, enhancing the ability of these cameras to protect homes, businesses, and institutions.

Two of the most popular resolutions for security cameras in today's market are 720p and 1080p. But which one is right for you?

This blog post aims to explain what 720p vs. 1080p means and then provides a comprehensive comparison of these two types of security cameras to help you make an informed decision.

720p vs. 1080p: What You Need to Know

Understanding Resolution

Before delving into the comparison, it's crucial to understand what is meant by 720p and 1080p. In essence, these numbers refer to the vertical resolution of the camera or the number of pixels in the vertical line of an image.

The "p" stands for "progressive scanning," which means the image is not interlaced. Progressive scanning produces smoother, cleaner images.

A 720p camera has a resolution of 1280x720 pixels, while a 1080p camera has a resolution of 1920x1080 pixels.

Image Quality

Image quality is, without a doubt, one of the most critical aspects to consider when purchasing a security camera. The higher the resolution, the clearer and more detailed the image.

A 1080p camera, with its higher pixel count, will deliver a sharper image compared to a 720p camera. This superior image quality can make a significant difference when you need to identify faces, license plates, or other specific details.

However, it's important to note that while a 1080p camera provides better image quality, the human eye may not always perceive this difference, especially on smaller screens.

So, if you're monitoring your security feed on a smartphone or small monitor, the distinction between 720p and 1080p might be less noticeable.

Storage and Bandwidth

The increased resolution of 1080p cameras comes with a trade-off: these cameras require more storage space and bandwidth.

In other words, a day's worth of footage from a 1080p camera will take up significantly more space compared to 720p footage. If you're using a cloud storage service, this could also mean higher storage space expenses.

The same goes for bandwidth: a 1080p camera will consume more Internet bandwidth, which could slow down your network, particularly if you have multiple cameras installed.

Low-Light Performance

When considering the performance of security cameras in low-light situations, it’s crucial to remember that resolution isn't the only factor at play.

Sensor size and type, lens quality, and the presence of technologies like infrared (IR) illumination or Wide Dynamic Range (WDR) can greatly influence a camera's low-light performance.

That said, given equal conditions, a higher-resolution camera, like a 1080p, would generally deliver better results due to its ability to capture more detail.

Usage Scenario

Your specific use case will largely determine whether a 720p or 1080p camera is more suitable for you.

If you need to monitor large areas or require detailed images for identification purposes, a 1080p camera might be the better choice.

On the other hand, if you're more concerned about general surveillance and don't need to capture fine details, a 720p camera should suffice.

If budget is a major concern, and storage and bandwidth are limited, a 720p camera would be more economical.

Cost

Cost is another factor that differentiates 720p and 1080p cameras.

720p cameras tend to be less expensive due to their lower resolution. In contrast, 1080p cameras are often priced higher due to their superior image quality and the technology involved.

However, prices for high-definition cameras have been dropping in recent years, making 1080p cameras more accessible to those on a budget than ever before.

Other Factors to Consider

In the end, the choice between 720p and 1080p resolution is just one part of the puzzle.

To get the most out of your security camera system, consider other key factors like camera placement, light conditions, field of view, and additional features your camera may have, such as motion detection and audio recording.

Remember, a security camera, irrespective of its resolution, forms part of a larger security strategy designed to keep your premises safe.

Resolution is a top consideration when deciding between purchasing 1080p or 720p security cameras. While both are suitable for indoor or outdoor use, they differ in the level of detail and clarity for each model—and consequently, how well intruders or vandals would be effectively identified from their footage.

720p models are adequate for many users, and cost about the same as more sophisticated cameras. Those featuring 1080p require more storage and bandwidth, but also provide greater detail for not too much higher a price. 

While either camera is a solid option, higher-resolution surveillance is the slightly better choice, if your budget permits. 

The following is a helpful breakdown of some of the many advantages of 720p- and 1080p-resolution security cameras.

 

What Are 1080p & 720p Security Cameras?

720p models are adequate for many users, and cost about the same as more sophisticated cameras. Those featuring 1080p require more storage and bandwidth, but also provide greater detail for not too much higher a price. 

It’s important to first understand resolution designations. These represent the vertical pixel (p) quantities—tiny dots of color—in recorded images. This affects how much a picture can be enlarged without sacrificing detail—the higher the resolution, the bigger the image.

1080p signifies high definition: 1920 pixels in width and 1080 in height, or a 16:9 widescreen aspect ratio. 720p cameras feature older technology, though legacy installations can be easily integrated with newer systems.

 

Differences Between 1080p & 720p Security Cameras

While 1080p doesn’t seem to provide much greater resolution than 720p, its total picture size actually contains twice as many pixels, since width increases proportionally as images become larger. This can help with better long-distance identification and recognition.

Every area to be monitored demands unique camera specifications, depending on size, shape, and other factors. Smaller, well-lit spaces with a clear field of view can be effectively covered by 720p systems, while larger spaces require an upgrade.

 

 

Camera Memory & Streaming

Higher resolution captures greater details, but also requires more memory. A one-hour, 1080p recording uses 675 megabytes (MB) of space, while the same video at 720p consumes only 288 MB.

It’s important to have enough storage to cover the full duration of when you’ll be away. If you regularly go on vacation, you’ll need enough memory card space to record at least one week of footage.

Real-time video streaming to a mobile device will be easier with 720p quality due to its lower bandwidth requirements. Most internet connections can easily stream at 1080p without issues, but a slowdown may cause lag with higher-resolution cameras.

 

Affordable Storage Space

Even when recording continuously for one week, a 1080p camera will consume only 113 gigabytes (GB) of space. Many modern cameras also have advanced features such as motion sensors and video analytics. Since these are activated only when movement is detected, they extend memory, storage, and battery life.

With cloud storage, some video systems might not even require a memory card. Remote video monitoring captures real-time footage accessible from any mobile device. Varying in price and plans, subscription-based cloud storage holds up to one month of space.

With the advent of cloud storage, some video systems might not even need a memory card. Remote video monitoring enables real-time recordings accessible from any mobile device.

 

Detail Level & Identification

Before selecting a security camera, consider its purpose: to identify or recognize intruders and occupants. The terms recognize and identify are industry standards regarding qualified image sizes.

Video requires a picture at least 20 pixels wide for a viewer to recognize someone from it. Depending on lighting conditions, a legitimate identification requires an image between 40 and 80 pixels.

 

Proximity & Image Resolution

A higher-resolution camera packs more pixels into an image, so it aids with recognition and identification at greater distances. 1080p footage, therefore, is better for deciphering identifications from longer ranges and bigger properties. 

720p footage is high enough quality to identify someone looking directly at the lens from across an average-sized family room with good lighting. Real-life scenarios add another layer of complexity, posing the questions: What if the intruder isn’t looking directly at the camera? What if their face isn’t visible, but a small identifying characteristic is?

No specific system can capture every scene, however a higher-resolution security camera provides a slightly better chance of collecting important details. Stiffer competition has lowered the price of 1080p cameras comparable to 720p models. An upgrade could be worth the slightly higher cost. 

 

Best Uses for 1080p & 720p Cameras

 

1080p cameras are best for recording larger images for longer time periods. Real-time video streaming is easier with 720p due to its lower bandwidth requirements. Depending on the area to be monitored, less cameras but featuring higher resolutions could be utilized. 1080p cameras can effectively safeguard residential yards, walkways, driveways, and more. They’re also ideal for surveilling commercial storefronts, parking lots, and internal employee areas.

Bullet and dome cameras can deter so-called porch pirates, intruders, and vandals. These are also suitable for monitoring employee productivity, capturing criminal activities, and ensuring public safety in commercial settings.  

Closed-circuit television (CCTV) cameras and systems are additional options for critical surveillance of commercial businesses, schools, and public gatherings. This technology can also assist law enforcement with identifying and possibly  apprehending potential perpetrators. 

1080p cameras are best for recording larger images for longer time periods, and real-time video streaming will be easier with 720p quality due to lower bandwidth requirements.

 

Which Camera Is Best?

As outlined above, both cameras will provide surveillance, but the optimal model will depend on a number of factors, including  size and specifics of the property or area to be monitored. While 720p cameras may suffice for smaller coverage zones, upgrading to a 1080p model may be worth it, since there’s a minimal price differential and it captures footage at a greater resolution. 

If you’re still unsure, or have further questions regarding cost, clarity, or resolution, it’s best to consult with a reputable and experienced security provider such as General Security, for guidance.
