VIDEO COMPRESSION SECURITY CAMERA
A video compression security camera is a surveillance camera that uses video contraction technology to reduce the size of video files it records and streams. This saves storage space, minimizes bandwidth usage, and allows faster transmission across networks.
HERE'S HOW IT WORKS
The raw video data is extensive when a camera captures images. Compression algorithms eliminate redundant or unnecessary data while maintaining the highest possible visual quality.
Perform surveillance recording 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.
A video compression security camera is a valuable tool. When your security system has bandwidth and storage limitations, also considering the type of security camera lens. Video files that are compressed will take up less space. Allowing you to store more videos or keep the files for longer periods. However, if your video is shortened too much, the image quality may remain uncompromised. For this reason, it is essential to choose the right film compression technology. This for having the best possible balance between video contraction and image quality.
VIDEO COMPRESSION SECURITY CAMERA - WHAT IS A CODEC?
There are two types of codecs – lossy and lossless. Most film compression is base on the lossy s video contraction format. Which shorten data to lose some of the original information. In lossless camera recording compression, no pixels change, so the image looks the same after decompression. Also, with lossless security compression. Every single bit of data initially in the file remains after the file is uncompressed. Though lossless surveillance film compression is adequate for video contraction. 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.
COMMON FILM COMPRESSION FORMATS
H.264 (AVC)
It is the most widely used format. It offers a good balance between quality and file size.
H.265 (HEVC)
It is newer and more efficient than H.264; it offers more space while maintaining quality
MJPEG
Compresses each frame individually; simpler but less efficient.
THE COMPRESSION FORMAT FOR ITS CONFIGURATION
The film compression format for your types of cameras for security configuration depends on several key factors: storage capacity, network bandwidth, and desired video quality.
RECOMMENDATION
If your cameras and recorder support it, the H.265 or H.265+ is the best choice for modern systems, especially if you use 4K cameras or cloud storage.
HOW DO I CHECK THE COMPRESSION SUPPORT OF MY CAMERA?
Check the camera specifications
- Manufacturer’s website: Search for your camera model and find the technical specifications page.
- Search for terms such as: “Video contraction” and “Supported codecs.”
- You will typically see formats like H.264, H.265, H.265+, or MJPEG listed there.
Access the camera web interface
If your camera has a browser-based configuration page:
- Log in to the camera using your IP address.
- Go to Video Settings, Broadcast Settings, or Encoding Settings.
- There should be a drop-down menu or selection for the compression format (e.g., H.264 / H.265)
Note: You may see different settings for “Main Stream” and “Sub Stream” and can set a different compression for each.
Use the mobile app or NVR software
If you are using an NVR application or software:
- Open the camera settings within the app or software.
- Navigate to the video or streaming settings.
- The compression method must be selectable or visible there.
Refer to user manual or quick start guide
These include tables listing supported resolutions, frame rates, and compression types.
Ask for help or check packing
If you cannot find the information online, contact the manufacturer’s sortation team. Or check the box for the wine camera in the compression standards, which are often printed on the label.
BENEFITS
SAVES STORAGE SPACE
Film compression helps save storage space by reducing the size of video files without significantly compromising quality. Security images from high-resolution cameras can quickly fill hard drives or cloud storage. By using advanced compression formats such as H.264 or H.265. Security systems can store much more material in the same storage device. Which allows longer retention periods and reduces the need for frequent updates or additional hard drives.
REDUCES BANDWIDTH USAGE
Film compression reduces bandwidth usage by minimizing the data transmitted from the camera to remote recording devices or viewers. Besides, this is especially important for IP cameras broadcast over a network or the Internet. Where high-resolution video can cause delays or connectivity issues. Basically, using efficient compression formats like the H.265. Additionally, the camera sends optimized and smaller video streams, ensuring smoother live viewing, faster playback, and better performance even with limited bandwidth connections.
REDUCES COSTS OVER TIME
Video coontraction reduces costs over time by reducing the need for large storage systems. Besides, high-bandwidth internet connections, and frequent hardware upgrades. Definitely, compressed video files take up much less space. Which means fewer hard drives or cloud storage plans are needed to retain the same amount of footage. In addition, lower bandwidth usage can decrease monthly internet expenses, especially in multi-camera business environments. Also, in the long run, these savings add up, making compression a cost-effective solution for maintaining an efficient and scalable security system.
SUPPORTS MORE CAMERAS IN A SINGLE SYSTEM
Video contraction supports more cameras in a single system by minimizing the data each camera transmits and stores, reducing the overall network load and recording device load. Basically, in large surveillance configurations, uncompressed or inefficiently compressed video can quickly overload system resources, resulting in delays, lost material, or limited scalability. Also, by using advanced compression formats such as H.264 or H.265, security systems can handle multiple high-resolution video streams simultaneously; this allows for extended coverage and improved performance without the need for expensive storage or network infrastructure upgrades.
IMPROVES REMOTE ACCESS PERFORMANCE
Device compression improves remote access performance by reducing the size of video streams, allowing the material to load faster and play more smoothly on smartphones, tablets, or computers. Basically, compressed video formats such as H.265 consume less bandwidth, which is especially beneficial for users viewing archive material via mobile data or slower internet connections. This means fewer buffering problems, faster load times, and a more responsive experience when accessing live or recorded video remotely, ensuring users can effectively monitor their property from anywhere.
ALLOWS HIGHER RESOLUTION RECORDING
Video contraction enables higher-resolution recording by efficiently reducing file size. This allows cameras to capture and store detailed images without overwhelming storage systems or network bandwidth. Recording in HD, 4K, or higher resolutions would require a large storage capacity and high-speed data transmission without compression. Besides, compression formats such as H.265 make it convenient to use high-resolution cameras, ensuring clear and crisp video that captures essential details like faces, plates, or movements while maintaining manageable file sizes.
HOW DOES COMPRESSION AFFECT VIDEO QUALITY?
Compression affects the quality of the video by removing or simplifying parts of the video data to reduce the size of the archive. Depending on the level of compression and method used, this can sometimes result in a loss of detail or visible artifacts.
HERE'S HOW IT WORKS
Lossy compression (such as H.264 or H.265) removes data the algorithm considers less critical, such as repeated background details or minor color changes.
- Light compression: Minimal loss of quality, Good visual clarity.
- Heavy compression: This can lead to blocked, blurry, or ghosting images, especially in fast-moving scenes.
Lossless compression keeps all the video data but does not reduce the size of the archive as much. It retains complete quality, but it is not practical for most surveillance systems due to high storage demands.
