Buying a video camera module can be complicated. Models vary not only in size and capabilities but also in price. You can spend a lot of money on a fake one. Before you buy a video camera module the considerations below will help you in the selection of the perfect one.
- Resolution: The resolution is the most important and basic feature of a dvp camera module and any basic face recognition application. You must buy the best camera module with a reasonable hog resolution because you do not want the image or video to be pixelated or extremely unclear. If you have to recognize the faces in the footage, you must see them clearly. Also, a camera module with high definition or HD is easily available and affordable at cbritech.com.
- Aperture: The aperture is related to the size of the opening at the back of the camera module lens and it controls how much light is passed on the image sensor of the camera. When the aperture opening is narrow, lens light is passed on the aperture opening image sensor and therefore the exposure is lower. When the aperture opening is wide, more light is passed on the image sensor and therefore the exposure is higher.
- Focal length: The focal length is the distance between the optical center of a lens and the camera image sensor and this is measured in millimeters. The focal length of the lens indicates its ability to converge light. The shorter the distance is, the more sharply it bends the light, and the larger the field it’ll be able to squeeze into its image circle. The camera module for face recognition offers the best focal length for a short-distance shoot. When the focal length is longer the physical length of the lens becomes longer and vice versa. Focal length directly affects how much image is shown on the camera.
- Image format: The image format is one of the major points to consider when buying a camera module for face recognition. The image format is the diameter of the camera module lens. The image format of the lens is directly affected by the image sensor size on the camera. In order to obtain the complete image from the lens, the image format of the lens should be equal to or greater than the size of the image sensor.
- Shooting mode: Most camera modules have a mode of setting. These are the basic modes;
- Manuel
- Aperture priority
- Shutter speed priority
- Program
- Auto
- Speed of performance: File size or megapixel is what most people first look at when buying a camera module. The higher the megapixel, the sharper the photo or the video will look. It also corresponds to the price of the video camera module.
- Types: Based on the position, there are 2 types of camera modules: a front video camera module and a rear video camera module. The front camera module is mainly used to take selfies and video calls and has only one lens. Today the high-end front camera is integrated with the time-of-flight (TOF) camera to realize facial recognition. The use of TOF cameras is safer and can unlock with a light. The rear camera module is used to take photos of others and videos; these are always flashlight rear camera modules. According to the number of cameras, we can divide the rear camera into 3 types: single camera module, dual camera module, and triple camera module.
With the above tips, we are looking forward to seeing you buy an amazing video camera module for your projects.
