As 4K TVs and monitors have become increasingly more affordable over the years, it is starting to surpass 1080p as the most commonly known and required high definition resolution for cameras as well. With its advantages and disadvantages, how do you make the right choice for your business? We have joined together our best advice for businesses searching for a new security camera system.
What is 4K?
4K does not mean 4 megapixels, a typical misunderstanding! 4K really corresponds with approximately 8 megapixels . That is around 4 times the particular resolution of a standard high definition 1080p image. We discussed the differences among 4K, 4MP, and 1080p in-depth on our 4K compared to 4MP blog post if you are searching for a detailed explanation.
More Pixels = Much better Image, Right?
While a higher resolution camera gives the potential for a better quality image, which is not always the case. There are many factors that affect the overall quality of the video clip, such as performance in low lighting and wide dynamic range (WDR), frame rate, sensor size, and the ability of the lens to zoom and focus optically. The quality of the camera is often not the most crucial factor in camera selection.
4K Comes With a Cost
With the rise of 4K security cameras, and many options at rock bottom prices online, why would anyone choose a system with less than 4K quality? As with all technology, 4K comes with a cost, and that cost is a tradeoff between quality, performance, and cost. A manufacturer who has designed a low price 4K camera has made significant sacrifices that result in less reliable or durable cameras, and poor performance in low or dynamic lighting conditions. There are great 4K security cameras out there, but they are not inexpensive!
Increased Storage Requirements
More pixels means bigger image size, and video storage capacity is already a major limitation meant for security systems. With standard picture compression, this can mean that a 4K video requires twice as much storage as a 4MP video, and 4 times as much as a 1080p video. Several systems come with advanced compression, like Uniview’s H. 265 Ultra codec, which can minimize this issue. For example , an Uniview 4K camera uses merely a third more bandwidth than their own 5MP, even though the resolution is 60 per cent higher!
Requires A lot more Processing Power
Complete security camera systems with standalone network video recorders (NVR) are essentially computers designed specifically to operate camera systems, and they have run on the processor just like any other computer. The processor is constantly working to decode the video sent by the cameras and report and display that video.
The higher the resolution, the particular harder the processor has to work. Not all NVRs are compatible with 4K cameras, and many systems that are compatible can be overloaded by too many 4K cameras. A system that is overloaded may be laggy and unresponsive, and may also result in cameras dropping offline suddenly.
Viewing in Full Resolution is Difficult
If you plan on watching your camera system on a 4K TV or monitor, it might seem to make sense to get a 4K camera, but do you know how many 4K cameras can be viewed at a time in full quality on a 4K TV? Only one during a period! Most users like to view several cameras at a time, our most commonly utilized viewing mode is probably 8 cameras at a time, and our systems support viewing up to 64 simultaneously. If you’re going to view multiple 4K digital cameras at the same time on a 4K monitor, they have to be viewed in a lower quality, simply because there are not enough pixels on your own 4K TV.
The Cabling is the Same
If you are concerned that having a lower resolution camera system installed may prevent you from ever upgrading in order to 4K, don’t worry. All IP-based systems are connected using system cables, and while we recommend setting up CAT6 cabling for security systems, CAT5E is sufficient for a 4K digital camera system. This means that if you want to upgrade to 4K in the future, when the price comes down and quality has gone upward, you will be able to remove your old digital camera and install the newest 4K camera using the same cabling.
4K Does Have Its Benefits
There are benefits to 4K digital cameras, particularly when viewing playback video. Although it is difficult to view multiple cameras in full 4K at the same time, playback usually focuses on one camera at a time. 4K gives the user a greater ability to digitally zoom in, which is important because it is impossible to adjust the optical zoom on playback footage. Digital zoom increases the size of pixels, possibly enabling the viewer to see greater detail on small objects within the frame.
There’s simply no denying that when comparing apples to apples, a 4K camera from the same manufacturer, with the same features and construction, and a proportionally larger sensor, is going to perform better than a lesser resolution camera. So , if it is within your budget, go for it, you will truly be amazed by the image produced by a good 4K system. However , it is in our experience that you will be significantly less amazed by a cheap 4K camera, and you may get that a lower resolution, higher quality camera outperforms in many conditions.
