Video Encoding

Video encoding is the process of taking raw video data and compressing it into a smaller, manageable file while maintaining acceptable visual quality. This is crucial for efficient storage, transmission, and streaming of videos. Imagine a video as a collection of individual images (frames) displayed rapidly in sequence. Each frame contains a lot of information (colors, pixels, etc.), making the raw video data quite large. Video encoding utilizes algorithms to remove redundancies and compress the data, significantly reducing file size without sacrificing too much quality.

H.264, H.265, H.265+ & Ultra 265:

These are all video codec standards, meaning they define specific ways to encode and decode video data. Common codecs include:

  • H.264 (AVC): This widely used codec offers good compression and is compatible with most devices. However, it might not be ideal for high-resolution content as the file size could still be significant.
  • H.265 (HEVC): This newer codec provides even better compression (up to 50% smaller files) compared to H.264 at the same quality level. This makes it suitable for high-resolution videos and bandwidth-limited situations.
  • H.265+: This is a proprietary technology typically available on specific encoder or decoder chips. It promises further improvements over H.265 by utilizing additional encoding techniques. However, compatibility with H.265+ might be limited compared to standard H.265.
  • Ultra 265: Similar to H.265+, this is another proprietary technology that claims even better compression and quality compared to H.265. Again, compatibility might be limited to specific devices or software.

Choosing the Right Codec:

The best codec for you depends on various factors:

  • Video resolution and quality: H.265, H.265+, and Ultra 265 will be more efficient for high-resolution content.
  • Target audience and compatibility: Ensure the chosen codec is widely supported by devices or software your audience uses.
  • Bandwidth limitations: For situations with limited internet bandwidth, using a more efficient codec like H.265 or newer versions can be beneficial.
  • Processing power: Encoding with newer codecs like H.265+ and Ultra 265 might require more processing power compared to H.264.

Basic Information About CCTV
Basic Information About CCTV

CCTV, which stands for Closed-Circuit Television, is a video surveillance system that transmits signals over a private network rather than a public broadcast. This means that the footage captured by CCTV cameras is only accessible to authorized viewers, unlike broadcast television that anyone with a TV can tune into.

IP CCTV Camera
IP CCTV Camera

 IP CCTV, or Internet Protocol Closed-Circuit Television, represents a modern approach to video surveillance utilizing digital technology and network connectivity. Unlike traditional analog CCTV systems, IP cameras capture and transmit video data as digital packets using the internet protocol (IP). This enables several advantages and advancements over its analog counterpart.

Analog CCTV Camera
Analog CCTV Camera

Analog CCTV, the original video surveillance technology has been around for decades and paved the way for modern security systems. While surpassed by newer IP technology in some aspects, it still holds its own in specific applications due to its simplicity and affordability.

Difference Between Analog and IP CCTV Camera

BNC Connector: BNC is a connector for coaxial cable that is most commonly used for CCTV installations. BLC (Back Light Compensation): This is a feature of security cameras that automatically adjusts the image to compensate for bright light to give more detail on the darker areas of the image. For example, use is to focus on the detail of the face of a person that has the sunlight shining from behind. Brightness: This changes how light the image appears to be. Its value is different in darkness from that in daylight. For example, car headlights' lights appear brighter at night.

we must check the camera's cable connection and power source. Normally, a problem comes from the wire trying to break toward the middle but not completely broken. The RJ45 jack is rusted(due to dew and water).  The PoE and the power supply may not work properly. For this, we have to change the cable or we can check by removing the camera and connecting it to a shorter wire. We can also test it by changing the switch's port and the power adapter.
