The penetration rate of security cameras is increasing year by year. As the need for home and commercial security cameras increases and the price gradually decreases, many people want to have a detailed understanding of surveillance cameras. This article provides a comprehensive explanation of the composition and structure of surveillance cameras from the inside to the outside, helping you to have a comprehensive understanding of surveillance cameras.

First of all, when you get a security camera, the first thing you should look at is the camera body. When you open the camera housing, you can see the internal structure of the camera, which are the main parts, such as the CCD, lens, infrared light board, and lens mount.

1. Surveillance camera housing: Surveillance camera housings are usually divided into waterproof cameras, dome cameras, and box cameras. The appearance of a security camera depends mainly on the exterior, which is also one of the determining factors of the price of the device. Even with the same configuration, different security camera exteriors can double the price of the device. This is generally the main source of profit for security camera manufacturers. In addition, OHWOAI's wireless security camera set is IP66 waterproof and dustproof and can withstand use in harsh outdoor environments. It is also recommended for stores, warehouses, parking lots, factories, power plants, etc.

2. CCD: CCD is a type of signal transmission path in a semiconductor chip. Semiconductor elements are arranged in a row, and signals are transmitted by passing electric charges between adjacent elements in a bucket brigade style. CCDs are mainly made up of chips from two manufacturers, Sharp and Sony, and there are also solutions from Korea and Japan. Although the chip solutions offered on the market are basically similar, due to differences in parts, some use completely domestic parts, some use completely imported parts, and others use mixed parts, which results in subtle differences in price and performance. This is also one of the main sources of profit for manufacturers.

3. Infrared sensor: The key to infrared sensors is the difference in the light core, and the price difference between each light core is large. Generally, the main light cores are Guang Lei and Ding Yuan.

OHWOAI's poe security camera is equipped with 6 high-quality infrared LEDs and 6 white LEDs. When set to full color mode, the white LED lights will turn on at night, allowing you to take color photos even in the dark.

4. Lens: Lenses are an essential part of a surveillance system, and they work with CCD cameras to project distant objects onto the CCD sensor. There are various types of lenses, which can be classified into wide-angle, standard, telephoto, focal length and variable focal length lenses according to their focal length. The selection of the appropriate lens directly affects the quality of the image, so it is necessary to select the lens appropriately in actual applications. OHWOAI security cameras are equipped with a 5x optical zoom function, and the zoom function allows you to zoom in and out freely for a clear display. The latest video compression standard "H.265" reduces network load for 4K ultra-high resolution data, preventing image defects such as image distortion and frame drops, and reduces the volume of recorded video data to half of the conventional capacity.

5. Other accessories: Other accessories include some combination connection parts, such as lens mounts, LAN cables, mounting screws, copper posts, etc. All these accessories are necessary, but they are usually selected based on the camera design.

The main accessories for surveillance cameras include surveillance camera peripheral accessories, surveillance camera lenses, surveillance camera power supplies, surveillance camera brackets, pedestal decoders, etc.

These components work together to make up a surveillance camera and help you better understand its working principle and structure. OHWOAI continues to provide high quality security cameras to ensure that customers receive superior security solutions.
