Hikvision ball-head camera
Hikvision's dome camera was one of its many surveillance camera products. It consisted of a body, a fixing frame, a ball head, and adjusting screws. The ball head had a shell and a lens. The bottom plate of the body and the wall formed a space, and the fixing frame was located in the space. The bottom plate is provided with an accommodating groove with a large top and a small bottom and a first through hole on the outer side. The shell of the ball head is provided with a gripping part, and the ball head is assembled in the accommodating groove, and the gripping part is below. The fixing frame is provided with a second through hole. When the adjusting screw passes through the first through hole and is in threaded connection with the second through hole, the ball head can be clamped tightly to fix the shooting angle of the lens. When the adjusting screw is loosened, the fixing frame can move up and down so that the ball head can be rotated to adjust the shooting angle of the lens. There are many models on the market, such as the 20,000 - 4,000,000 POE power supply dual-light full-color dome camera surveillance camera, such as the DS -2sc2q140my-e, etc. Different models have different prices and performance characteristics, which can meet the needs of different scenarios such as outdoor 360-degree surveillance.

How does Hikvision adjust the focus of the surveillance camera?
The following is how to adjust the focal length of the surveillance camera: 1. Use remote control: Most Hikvision cameras are equipped with a dedicated remote control, which can be adjusted by the focal length adjustment button on the remote control. Generally, sliding the remote control wheel up or down can increase or decrease the focal length, and sliding the wheel to the left or right can change the angle of view. When operating, pay attention to maintaining the distance between the remote control and the camera. 2. Use mobile APP: Some Hikvision cameras support mobile APP zooming. First, download and install the official APP of Hikvision and log in to your account. Find the corresponding camera device, click to enter the settings interface, and select functions such as "lens zooming" or "focal length adjustment". During the operation, make sure that the phone is connected to the camera. 3. Use computer software: Some Hikvision cameras can adjust the focal length through computer software. After downloading and installing the official software of Hikvision, he logged into his account and found the corresponding camera equipment. He clicked to enter the settings interface and selected functions such as "lens zooming" or "focal length adjustment". During the operation, he made sure that the computer and the camera were connected normally. In addition, you can choose a model with manual adjustment function when you buy it, and adjust the focal length by rotating the lens.

Lifting camera head
The elevating camera was a camera design that was once popular on mobile phones. It has many advantages: First, it completes the full screen, does not occupy the space of the phone screen, brings a better visual experience to the user, and makes the field of vision wider; Second, it prevents interference. The lifting camera at the top of the phone can prevent fingers from blocking the line of sight, which is conducive to taking good photos; Third, it protects privacy. When not in use, it is hidden. If it is secretly photographed, the raised camera is easy to be discovered. However, there were also many drawbacks to the camera: 1. ** Mechanical structure limitations **: It is installed on top of the phone, and it relies on the internal lifting mechanism to move up and down under the drive of the motor. This increased the wear and tear of the mobile phone and the threat of its lifespan. The frequent lifting and lowering would cause the loss of components, increase the difficulty of repair for consumers and the hidden dangers of after-sales for manufacturers, and the cost of maintenance in the later stages would be higher. 2. ** Higher cost **: The design difficulty increases, and the increase in mechanical materials leads to an increase in the manufacturing cost of the mobile phone. These costs will eventually be allocated to the retail price of the mobile phone. The consumers tended to prefer cost-effective phones, and the high cost made it more difficult to sell the phones. Moreover, in order to achieve the camera lift, the internal space of the phone body was occupied, and other functional components might be sacrificed, resulting in a reduction in the functionality of the phone. 3. ** Not in line with market demand changes **: During the development of smart phones, the market pursued thin, fast, and portable phones. Lifting the camera required a certain thickness of the body to support it, and its thickness was usually thicker than ordinary mobile phones, which did not meet the requirements of being thin and light. At the same time, consumers were more concerned about its dust-proof and waterproof performance. When the camera was raised, the phone might fall into the water and damage the body, but the camera integrated phone did not have this problem. 4. ** Other problems **: There are also problems such as taking up a large space, increasing the weight of the body, the failure rate of the mechanical structure, and the low durability. However, with the development of technology, such as Xiaomi's Redmi K80, it may adopt a new lift camera patent technology. This new technology has a simple and reliable structure, convenient operation, and low cost. It uses a planar link mechanism to transmit power so that the overall movement is in a plane, reducing the thickness of the phone. The phone can be made thin and light, which is expected to overcome some of the drawbacks of the traditional lift camera. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
