SURVEILLANCE VIDEO COMPRESSION
Security camera video compression works with one or more algorithms, such as creating a compressed file. That means it weighs less when viewed or stored. However, as it weighs a lot, it must compressed to reduce size. The file to compress it can lose image quality.

SECURITY CAMERA VIDEO COMPRESSION
Perform Surveillance video compression through a codec that works on one or more compression algorithms. Compressing video from surveillance systems involves applying an algorithm to the source video to create a squeezing file that is ready for transmission or storage. The applied inverse algorithm produces a video that shows virtually the same content as the source video to play the compressed file. The latency takes time to compress, send, decompress, and display a file—the more advanced the compression algorithm, the higher the latency.
Once a security camera video compresses, its original format changes into a different form (depending on the codec used). Video codecs use two algorithms that work together (encoder/decoder). Usually, the incompatibility of video codecs succeeds if each other takes different standards. You can´t decompress video content compressed using one bar with a different standard. The video player must support an integration of the compressing codec to play the video file in that video format.
SURVEILLANCE VIDEO COMPRESSION - HOW DOES IT WORK?
A security camera video compression is a valuable tool when your security camera system has bandwidth and storage limitations. The squeezing video files will take up less space, allowing you to store more videos or keep the files for more extended periods. However, if your video is shorten too much, the image quality can remain uncompromising. For this reason, it is essential to choose the right surveillance video compression technology to have the best balance possible between video compression and image quality.
SURVEILLANCE VIDEO COMPRESSION - WHAT IS A CODEC?
There are two types of codecs – lossy and lossless. Most video compression is base on the lossy s video compression format, which shorten data to lose some of the original information. In lossless security camera video compression, no pixels change, so the image looks the same after decompression. With lossless security camera video compression, every single bit of data initially in the file remains after the file is uncompressed. Though lossless surveillance video compression is adequate for video compression, its major disadvantage is that it doesn’t reduce the data very much. Deformation. However, it achieves much smaller file sizes while still retrieving a pretty clear image.
Different surveillance video compression standards reduce data by various means. Hence, results differ in bit rate, quality, and latency. Video compression is an essential tool to help prevent network traffic from becoming saturated. What are the most popular surveillance video compression standard or compression schemes? There are three significant security camera video compression worldwide standards:
H264 VS H265 :
H.264 is another name given to MPEG-4 Part 10, also known as AVC (Advanced Video Coding).
H.264 security camera video compression is the newest and most efficient security camera video compression codec. It works by taking small groups of frames and evaluating them together as a series to eliminate duplicate content that appears in each frame without changing. H.264 offers higher shorten rates. It requires much less storage space than MPEG-4 and M-JPEG.
M-JPEG is the compilation of separately compressed JPEGs in a sequence, thus creating a video. It focuses on the quality of the image rather than the quantity, i.e., fewer frames per second and priority give to image resolution. This surveillance video compression is appropriate for megapixels, and many other security cameras are supported. Some advantages of M-JPEG include better decompression on the computer, better live viewing, and excellent image quality (consistently). M-JPEG is also unlicensed, making it accessible for the user and viewer. Another aspect that makes M-JPEG good is its robustness, and if one frame is dropping, it does not affect the video.
MPEG-4 uses techniques similar to M-JPEG, as far as putting pictures in a sequence. Essentially compares two compressed images and saves the photo. It holds only the difference from each additional sequential image, such as movement, thus saving time, memory space, and processing power. Sync audio and video and is excellent for real-time viewing. MPEG-4 was designed to support low-bandwidth applications.
SECURITY CAMERA VIDEO COMPRESSION : CONCLUSION
Surveillance video compression technologies such as Motion JPEG, MPEG-4, and H.264 allow users to transmit and record high-quality security videos without consuming much bandwidth. Even though the surveillance video compression industry is relatively mature, the new video compression H.265+ standard will improve image transmission.
