Auto Exposure Mode
When the camera is in AE (Auto Exposure) mode the camera will regulate the all the exposure settings itself to create the best image.

Shutter Speed
In manual mode the shutter speed can be adjusted. To choose the right Shutter speed you can use the 180 rule. The 180 degree shutter rule is a popular guideline among video makers for setting the shutter speed for proper exposure. It states that the shutter speed should be set at double the frame rate of the video being shot. For example, if a filmmaker is shooting video at 30 frames per second, the shutter speed should be set to 1/60th of a second in order to achieve proper exposure. This shutter speed creates a shutter angle of 180 degrees, hence the name of the rule. This rule has become a standard in the film industry to match what the human eye is used to seeing in real life.

Gain is an electronic light amplification of the video signal. This means that the light is boosted electronically, adding more voltage to the pixels on your image causing them to amplify their intensity and therefore brighten your image. This will result in a brighter image in conditions that wouldn’t normally allow it, like when there is insufficient light. The contrary of Gain is noise. The higher the Gain is set the more noise will occur.

Anti-Flicker is a feature that helps reduce or eliminate flickering images caused by fluorescent or other artificial lighting sources. It works by adjusting the shutter speed to match the frequency of the artificial light source. This helps to reduce the amount of flickering that occurs in the images.

Backlight compensation adjusts the exposure to compensate for overly bright background light. It is used to ensure that the main object is properly exposed and not lost in the shadows due to the intense background lighting. Backlight compensation works by increasing the exposure of the foreground and allowing more light to hit the object. This setting can be enabled or disabled.

Gamma is a setting that adjusts the contrast of an image. It is typically used to make subtle adjustments to the midtones and shadows of an image. It is an important tool to fine-tune the overall look of an image.  When adjusting the gamma of a camera, the result is a change in the level of brightness of midtones and shadows. If the gamma is too high, the overall image may appear washed out and lack contrast. If the gamma is too low, the image may appear too dark and lack detail in the midtones and shadows.

Auto White Balance
When the camera is set to auto white balance settings, it assumes that the light source is a neutral white. This means that the colors in the scene will be rendered accurately. However, if the light source is not neutral white, then the colors in the scene may be rendered inaccurately. In that case, the white balance settings should be manually adjusted to ensure that the colors in the scene appear as they should.

DEFOG reduces the effects of fog, mist, and other forms of moisture on the image being captured. It uses an infrared filter to block out the fog and mist, allowing the camera to capture a clearer image.

2D Noise Reduction
2D digital noise reduction is the simplest way to reduce video noise. It uses the temporal method for reducing noise. It compares pixels and removes ones that don’t appear in every frame. These irregular pixels are considered image noise. 2D Noise Reduction works best with low-resolution footage. With higher resolution footage, this method is virtually ineffective. While effective, this form of noise reduction can blur images or leave movement trails.

3D Noise Reduction
3D digital noise reduction uses an algorithm to compare pixels in a sequence of frames. First, it analyzes the pixels in each frame, and then it compares the frames to see which pixels move or change. It is highly effective at isolating pixels considered noise and generally better at eliminating that grainy look common with low-light video. 3D is also the better choice for videos with lots of motion because it does not create motion blur like 2D DNR. Additionally, 3D DNR works well on high-resolution footage, whereas 2D does not.

The camera sharpness is a measure of the quality of an image that is captured. It is determined by the level of detail that is present in an image, as well as the clarity of the image. A sharp image will have crisp edges and accurate color representation, while a blurry image will appear soft and may not have accurate color representation. You can adjust the level of sharpness according to your video scene.

Camera contrast It helps to make the video image more dynamic and interesting. It refers to the difference in brightness between different parts of the image. A higher contrast video image brings out more details and textures combined with intense dark and light areas, while a lower contrast video image will have a more subtle and calming effect.

Saturation is the density of a color. Higher saturation makes the colors appear richer, while lower saturation makes it appear paler.

Brightness is a term used to describe the overall light intensity of the image and is used to adjust the overall level of brightness of the image.

Auto framing
Auto framing is a technology used by cameras to keep a person or object in the centre of a frame and maintain the same size as the person or object moves. The technology works by using facial recognition, tracking and other algorithms to recognize a person or object in the centre of the frame and then use the camera’s intelligent motion detection to adjust the framing accordingly.

In auto mode the camera will automatically do auto framing in the room where it is placed.

In manual mode the camera works as an ePTZ camera. You will be able to manually zoom in/out and move the image up/down/left and right.

This function can be used in manual mode to directly do auto framing when you press the p/m button on the IR remote control.
