1080p vs 4K Security Camera

1080p vs 4K Security Camera: Detailed Comparison 

Choosing the right security camera resolution is crucial for capturing clear, usable footage. The debate between 1080p and 4K security cameras is more than just numbers—it’s about finding the balance between image quality, storage requirements, and cost-effectiveness.

Understanding the differences between these resolutions can help you make an informed decision tailored to your surveillance needs.

4K vs 1080p Security Cameras Compared

The resolution is the most significant difference when comparing 4K and 1080p security cameras. 4K cameras, also known as Ultra HD, are higher resolution cameras with a resolution of 3840×2160 pixels.

Such a camera records four times the resolution of 1080p Full HD cameras (at 1920×1080 pixels). This higher resolution translates to superior image quality with sharper, more detailed images.

It makes 4K cameras (vs. 1080p) the best bet for monitoring larger areas or situations where identifying fine details, such as facial features or license plates, is crucial.

However, these sharp images come at a cost—high-resolution 4K cameras require more storage space and more powerful hardware to process the higher volume of data. They also tend to be more expensive regarding initial investment and ongoing storage costs.

Also, 4K cameras may perform differently in low light conditions than their 1080p counterparts, often requiring more light to maintain high image quality.

On the other hand, 1080p cameras offer sufficient resolution for most standard surveillance needs. It is especially true for smaller spaces like front doors or single rooms in multi-tenant buildings. They strike a balance between delivering clear, detailed videos and managing storage and cost more efficiently.

While they may not capture as much detail as 4K cameras, 1080p cameras can still provide high-quality video surveillance for those on a tighter budget or with less demanding surveillance requirements.

In summary, the choice between 4K and 1080p security cameras depends on various factors, including the specific surveillance needs, available budget for purchase and maintenance, and the physical area needing coverage.

Application

1080p security cameras are widely used in scenarios requiring general surveillance, including residential areas, small to medium-sized businesses, and indoor spaces where detailed zooming is less critical. They provide a balance between good image quality and efficient storage use.

4K security cameras, with their higher resolution, are best suited for areas requiring detailed surveillance, such as monitoring large public spaces, high-risk environments, and multi-tenant buildings where capturing the finest details is crucial.

They offer superior clarity, making them ideal for facial recognition and license plate identification even over wider areas.

Pricing Options

1080p cameras are more budget-friendly, making them a cost-effective option for those needing comprehensive coverage without breaking the bank.

Their lower price point does not significantly compromise quality, offering sufficient clarity for most standard surveillance needs. The pricing will also depend on various factors, not just the video resolution.

4K Cameras come at a higher cost due to their advanced technology and the better image quality they provide. The investment is justified for environments where the highest level of detail is necessary.

Still, it’s important to consider the total cost, including the need for more powerful hardware and increased storage capacity.

Detail & Clarity

The big difference in video resolution between 1080p and 4k cameras directly impacts the level of detail and clarity. 4K cameras can capture more detail in a larger scene with the same number of cameras, reducing blind spots and the need for additional units. It makes them the best solution for monitoring activities with precision.

Features

While both camera types have various features, 4K cameras often include advanced functionalities such as enhanced zoom capabilities without compromising image quality. Their powerful processing hardware supports more sophisticated video analytics, making them a versatile tool in security surveillance.

Storage and Bandwidth

4K cameras require more storage space and bandwidth (when it is an IP camera) to handle the higher resolution and video data they generate. It necessitates powerful hardware and possibly additional investments in storage solutions.

1080p cameras, with their lower resolution, consume less bandwidth and storage, making them more manageable for systems with limited resources.

FAQs

Can you really tell the difference between 4K and 1080p?

Yes, the difference between 4K and 1080p is noticeable, especially regarding video surveillance cameras. 4K resolution offers significantly more detail and clarity, making identifying faces, license plates, and other important details easier. The higher resolution provides a wider field of view and allows for effective digital zoom without compromising image quality.

Are 4K CCTV cameras worth it?

4K CCTV cameras are worth the investment for areas where high detail is crucial, such as monitoring entrances, cash registers, or large spaces. They offer superior image quality and the ability to capture more detail with fewer cameras. However, the value depends on specific surveillance needs, available infrastructure, and budget.

Is 1080p good for a security camera?

1080p is still a good resolution for security cameras, providing sufficient detail for most standard surveillance needs. It’s a cost-effective solution that balances quality and storage requirements, making it suitable for smaller businesses or areas where ultra-high detail is less critical.

Is 4K better than 1080p for an action camera?

For action cameras, 4K is better than 1080p as it captures much more detail and offers a wider field of view. It is particularly beneficial for capturing fast-moving scenes with clarity. However, it requires more processing power and storage space.

Key Takeaways

When choosing between 4K and 1080p security cameras, consider the balance between detail, storage, bandwidth, and budget.

4K cameras offer unparalleled clarity and detail, making them the best solution for critical surveillance areas. However, 1080p cameras still provide excellent image quality for general monitoring purposes and are more budget-friendly.

Differences H.265 and H.264

Differences between H.265 and H.264



A codec is an encoder and a decoder. An encoder compresses audio or video so it takes up less disk space. A decoder extracts audio or video information from the compressed file. Video and audio compression is a complex technical process, but the basic aim of a codec is quite straightforward:

(a) Reduce the size of the compressed media file as much as possible, but...(b) Keep the quality of the decoded audio and video as good as possible.

What is H.264?
H264 (aka MPEG-4 AVC) is currently a mainstream video compression format. It is widely used in Blu-ray discs, internet sources like videos in YouTube and iTunes Store, web software, and also HDTV broadcasts over terrestrial, cable and satellite.

What is H.265?
H.265 (also known as HEVC, short for High Efficiency Video Coding, developed by the Joint Collaborative Team on Video Coding (JCT-VC)) is a video compression standard whose predecessor is H.264/MPEG-4 AVC. H.265 HEVC ensures to deliver video quality identical to H.264 AVC at only half the bit rate, including better compression, delicate image and bandwidth saving. It Support up to 8K, Support up to 300 fps. It is likely to implement Ultra HD, 2K, 4K for Broadcast and Online (OTT).

H.265 vs H.264: Differences between H.265 and H.264

In general, H.265 has several big advantages over H.264, including better compression, delicate image and bandwidth saving. For more detailed differences, please read H.265 vs H.264 comparison table.

4 pcs 2MP IP cameras for 1 month, stream: 4096Kbps. 
H.264 IP camera need 42G×4×30=5T=1×3T+1×2T, so need 1 pc 3T and 1pc 2T HDD. 
H.265 IP camera need 21G×4×30=2.5T, so need 1 pc 3T HDD only, save at least 1 pc 2T HDD cost.

Difference between 1080p and 2160p

Difference between 1080p and 2160p 

1080p

1080p (aka Full HD/ FHD and BT.709) is a set of HDTV high-definition video modes characterized by 1080 horizontal lines of vertical resolution and progressive scan(p), as opposed to interlaced, as is the case with the 1080i display standard. The term usually assumes a Wide screen aspect ratio of 16:9, implying a resolution of 1920x1080 (2.1megapixel) often marketed as Full HD.



2160p
2160p is an alternative name for 4K UHD, a resolution supported by UHDTV products and which offers four times the definition of 1080p. The number 2160 stands for a display resolution which has 2160 pixels along the shortest side, while the letter p stands for progressive scan or non-interlaced. In a progressive image, the lines of resolution of the image go from the top of the screen to the bottom. The only planned higher definition format for television is 8K UHD.

Resolution of Network Camera

Resolution of Network Camera
This time I will try to discuss the resolution of the image of the network camera. Resolution which is the number of pixels (pixel) different in each dimension that can be displayed. The greater the resolution of an image, the more have the number of dots and more detailed image will be displayed.
If you want to buy a camera network device that can display video images are detailed and clear, then you should choose a network camera that has high resolution. Currently network video camera technology has a lot to offer features Full HD resolution (1080p).But perhaps for the people of Indonesia arguably the price is still relatively expensive, because there are around 4 million more.

1080i VS 1080p The Difference

1080i vs. 1080p: What's the Difference?

Progressive (1080p) video is considered better than interlaced (1080i), but it's not always clear why; here's what's actually happening on your TV screen.
Today's HDTVs can display beautiful, 1,920 X 1,080-pixel video, but the actual quality of what you're viewing depends on the source material. A lot of the time, you're not seeing exactly 1080p. In fact, most TVs today have two modes with similar names: 1080i and 1080p. Both have the same screen resolution, so what's the difference between the two? Here are five things you need to know:

1080i video is "interlaced." 1080i video plays back at 60 frames per second, but that's a bit deceptive, because it's actually broadcast at 30 frames per second. The TV then displays those frames twice, the first pass is 1,920 X 540 for the even scan line field, and the second pass is 1,920 X 540 for the odd scan line field. The process by which this occurs is called interlacing. It contributes to a sense of motion and reduces perceived flicker.

1080p video is called "progressive scan." In this format, 1,920-by-1,080-pixel high-definition movies are progressively drawn line after line, so they're not interlaced. On paper, that may not seem like a huge deal. But in the real world, what you end up seeing looks sharper and more defined than 1080i, particularly during scenes with a lot of fast motion.
Sometimes 1080p is termed "Full HD" or "True HD," to distinguish it from 1080i or 720p video. Blu-ray discs contain 1080p video at 24 Frames Per Second, and then, using a method known as 3:2 pulldown, display it at 30 frames per second on screen.
Data compression can confuse the issue. Sometimes cable companies will deliver a 1080i picture, but then compress the data significantly in order to use up less bandwidth. The result can mean smeared details or pixelated color gradations in certain scenes. It's still technically HD, and still looks better than standard-definition cable, but it's not as good as it could be.
This also happens with 1080p streaming Internet video, but in that case, it's usually dependent on the speed of your data connection. In fact, Blu-ray is currently the only practical format for watching lots of pure 1080p content. Even the latest Apple TV, which supports 1080p streaming, does so in a compressed format that loses a bit of quality (although it still looks quite good).

Both formats look similar on smaller TVs. As a general rule, you need a larger TV to notice the difference between 1080i and 1080p. Depending on your eyesight, you can probably pick up the difference on a 32-inch LCD if you're particular about it. But most consumers don't really see a marked difference until at least a 42-inch screen, if not larger. In fact, many people are perfectly happy with 720p HDTV sets even at higher sizes; we recently named one, the 51" Samsung PN51E490B4F, best Choice for budget large-screen HDTVs.

1080p isn't even the best anymore. Technology never stands still, of course. Five years from now, you'll probably just want Ultra High Definition (aka 4K) video instead. (For a closer look at 4K video, check out What is Ultra HD?) But for now, if you're a videophile who appreciates a sharper picture, 1080p is definitely the way to go—both in HDTV capability and in the source material you're viewing.

Choose an HDMI Cable

How to Choose an HDMI Cable

Choosing an HDMI cable can be a complex task. There are several factors that must be considered in order to select the best HDMI cable to meet the user’s requirements:
·         HDMI standards compliance
·         HDMI Cable Categories
·         Cable length
·         Cable quality
·         Active cables
·         HDMI devices
·         Price

HDMI Standards Compliance
Each HDMI cable is rated to comply with a specific revision of the HDMI standards. A cable rated for HDMI 1.2a should meet the requirements of HDMI 1.0, 1.1 and 1.2, but is not guaranteed to meet the standards for HDMI 1.3.
HDMI Cable Categories
The HDMI standards define two cable categories. Category 1 HDMI cables support HDTV resolutions and frame rates. Category 2 cables are required for higher resolutions or higher frame rates.
Cable Length
The HDMI specification does not define a maximum cable length. HDMI cables are commonly available in 3′ to 50′ lengths.
Purchasing a cable longer than necessary will cost more money, but it will also increase signal loss due to attenuation.
Cable Quality
All other factors being equal, a cable that is built to higher tolerances using better materials will outperform a cable that is built merely to meet a standards specification. In addition, these premium cables will often provide longer service lives.
An HDMI cable can be made using 28 AWG wire, but a 24 AWG wire will create a sturdier cable that is more resistant to attenuation.
As with traditional analog stereo cables, premium HDMI cables are often furnished with gold plated connectors to ensure the best possible signal quality.
Active Cables
For specialized high end applications, some manufacturers are selling active HDMI cables. These cables use a variety of technologies that involve boosting the transmission distance or quality through the addition of electrical power to the cable connection.
Some of these active cables run over fiber optics or Cat-5 cable.
HDMI Devices
Another approach to supporting extremely long cable runs is to chain multiple HDMI cables together with amplifiers, repeaters, or equalizers.
