White Balance

White balance is a crucial setting in photography and videography that ensures objects appearing white are rendered white in your images, regardless of the lighting conditions. It adjusts the overall color temperature of your photos or videos to accurately represent the scene you're capturing. Our eyes are very good at judging what is white under different light sources, but digital cameras often have great difficulty with auto white balance(AWB) and can create unsightly blue, orange, or even green color casts. Understanding digital white balance can help you avoid these color casts, thereby improving your photos under a wider range of lighting conditions.

Understanding Color Temperature:

Different light sources have different "color temperatures," measured in Kelvins (K). Daylight tends to be around 5500K, while incandescent bulbs are warmer at around 2700K. If your camera doesn't properly adjust for the color temperature, white objects might appear orange under tungsten light or blue under fluorescent lights.

What is White Balance — How it Works and Why It Matters

How White Balance Works:

  • Setting the baseline: White balance essentially tells your camera what "true white" looks like under the current lighting. This reference point helps the camera adjust all other colors accordingly.
  • Multiple options: Cameras offer various ways to set white balance:
    • Auto White Balance (AWB): The camera automatically guesses the color temperature, but it's not always accurate.
    • Presets: Choose from settings like Daylight, Tungsten, Shade, etc., depending on the light source.
    • Custom White Balance: Capture a picture of a neutral object (like a white card) under the same lighting to set the reference point.
    • Kelvin: Manually set the color temperature based on known values.

Benefits of Accurate White Balance:

  • Natural colors: Accurate white balance ensures your photos and videos represent the true colors of the scene, enhancing realism and professionalism.
  • Creative use: Adjusting white balance can be used for creative purposes, like adding warmth or coolness to your images.

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
Difference Between Analog and IP CCTV Camera

Analog CCTV remains a budget-friendly option for basic needs, but its limitations become apparent when scalability, high resolution, and advanced features are desired. IP CCTV offers superior video quality, flexibility, and advanced functionalities, but requires a more complex setup and potentially higher initial costs.

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.
