Hikvision surveillance camera cable
There were many types of connection cables for Hikvision surveillance cameras. For example, there was a 12 Vac male to female power cable DC5521 male bus suitable for monitoring the extension cable camera, as well as Hikvision's national standard SS-1LN6-UE5 category 6 indoor monitoring oxygen free copper network cable. When connecting the camera, the order of the network cable interface has a corresponding relationship with the Class B network cable. You need to check the corresponding color of the camera network cable to determine the type of camera, and then refer to the corresponding table to connect. For example, the black wire of the camera is connected to the orange white wire of the Class B network cable, and the brown wire is connected to the orange wire of the Class B network cable. If a 4-core network cable was used for docking, the weak current technology was involved, but it was not clear which cables to dock. In addition, for the POE ball machine monitoring device, it combined power and data transmission functions, and power supply and video data transmission could be achieved through a network cable. When connecting multiple cameras, for example, when connecting a cable to multiple cameras in a PoE integrated video recorder, each network port needs to be connected to a cable to connect to the camera. You can also connect a cable from the network port to the Poe repeater, and then use two cables from Ji Lianbao to connect to two cameras. At the same time, pay attention to the transmission distance of the network cable. It is recommended to use a standard Class 5 network cable. The theoretical transmission distance is 100 meters, and it is recommended to control it at about 80 meters. Read more exciting novels for free
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. You can also install a stand with an adjusted focal length later, and adjust it flexibly according to actual needs. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
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. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Hikvision camera development kit Nvidia
Hikvision used an Nvidia CPU and a JetsonTX1 platform. There was a project that provided a Hikvision Webcamera development package for a variety of development languages, including C#, Mengmeng, Java, and Python, but there was no mention of a specific connection with Nvidia in terms of development packages. Therefore, based on the available information, it could only be known that Hikvision used Nvidia's CPU and other resources in its own products. There was no more information about the direct connection between the Hikvision camera development kit and Nvidia. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The smallest surveillance camera
The pinhole monitor was the smallest and most convenient monitor. It could be installed in a hidden place and was not easily discovered. If there was an internet connection, it could also be used for remote monitoring. In terms of size, the world's smallest SS-L1475 camera was about 4.4mm in diameter and 15mm in length. It could shoot 320x240-pixel-QVP video and had an LED flash at the top. In addition, there were some miniature monitors on the market that were less than the size of a jelly bean and could be easily placed in the palm of one's hand or hidden in other objects. However, these miniature monitors were usually used for security monitoring or spying. There was also a 12 * 12mm ultra-miniature color camera. Its appearance and workmanship were exquisite and beautiful. The wires were precise, and the structure was rigorous and reasonable. It was extremely convenient to install and use. It was small, flexible, and had low illumination. It could be carried around. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Surveillance camera with a lens
The surveillance camera was just a single video capture device. The resolution and resolution of the lens were higher than that of the computer's video head, but it could not catch up with professional digital cameras or DVs. In reality, cameras and lenses were mostly purchased separately. The user can calculate the focal length of the lens according to the size of the target object and the distance between the camera and the object to determine the required lens. The lens required by each user depends on the actual situation. It cannot be assumed that the camera (head) already has a lens and does not need to be equipped with another lens. The focal length of the lens determined the field of view of the camera. For example, a wide-angle lens was suitable for shooting in a large space and could capture more content. A telephoto lens was suitable for long-distance shooting and could see details in the distance. Indoors, they usually chose short focal lenses, such as 2.8mm or 3.6mm lenses, while outdoors, they chose lenses based on distance. Moreover, different focal length lenses had different imaging effects. Long focal length lenses could see more details of distant objects, but the field of view became smaller and the viewing range became narrower. Wide-angle lenses had a wide viewing range, but it might be difficult to distinguish some details. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The surveillance camera on the highway?
The video surveillance on the highway might have a camera function. For example, the violation camera was generally spherical in shape. Its function was to capture and punish the captured vehicle. Many traffic accidents were caused by parking violation. This kind of camera was installed in the no-parking section, and it was also installed in the parking area of the highway bus. Electronic eyes were used to detect illegal behavior while driving, such as running red lights, changing lanes, etc. Although there was no explicit mention of taking photos, detecting these behaviors usually required taking photos for evidence. Therefore, there were video surveillance cameras on the highway. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Focus the surveillance camera
If it was a general non-integrated surveillance camera, the method of adjusting the focal length was as follows: First, remove the camera, check the small screw like parts at the lens and loosen it, then turn the circle on the lens to adjust the focal length. When adjusting the focal length, it was best to take it off and adjust it while facing the monitor screen. If it was inconvenient to take it off, two people were needed. One person looked at the screen and cooperated with gestures or words, and the other person adjusted it next to the camera to achieve the best effect. It could also be adjusted manually. Some surveillance cameras had two buttons that could be rotated. One was used to adjust the distance and the other was used to adjust the clarity. There was another adjustment method: first loosen the fixing screw of the camera's rear focal length adjustment ring; adjust the zoom lens to the maximum telephoto position, and use the focal length adjustment ring on the lens to set the focal length until the image is the clearest; then adjust the zoom lens to the maximum wide-angle position, and turn the rear focal length adjustment ring until the image is the clearest; when switching from telephoto to wide-angle, repeat the above two steps until the image is in focus; finally, after the setting is complete, tighten the rear focal length adjustment ring. In addition, he added a new experience of adjusting the lens. He loosened the screw that fixed the standard lens, adjusted the magnification, and adjusted the lens to a telephoto state. Then, he zoomed in on the distant object, and then adjusted the focal length to make the close-up image clear. Then, he pulled the lens back to the wide-angle state by zooming out. The image he just shot should be a panoramic view. Don't adjust the focal length of this panoramic view (even if the image is blurry, don't adjust it). Go straight to the next step, which is to adjust the back focal length to adjust the image to the best picture. Finally, tighten the small screw of the lens, and the back focal length adjustment is completed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
