Longquanyi surveillance camera installation construction
The general process of installing the surveillance cameras in Longquan Posthouse was as follows: ** 1. Initial preparations ** 1. ** Communication of requirements and site survey ** - The construction party must fully communicate with the customer to understand the customer's requirements for the monitoring installation, such as the purpose of the monitoring (for anti-theft, monitoring the activities of personnel in specific areas, etc.), the scope of the monitoring (indoor, outdoor, specific rooms or areas, etc.), whether remote monitoring is required (remote viewing through mobile phones or other devices), etc. - Carry out a site survey to check the environment of the distribution site, including the structure of the building, the location of the power supply, and whether there are any obstructions. At the same time, they could bring samples for live demonstration, allowing customers to see the actual effect. 2. ** Plan Design and Price ** - According to the customer's needs and the site survey, the construction party drafted the construction plan, construction drawings, and equipment models, and submitted them to the customer for confirmation. - According to the design plan, the price would be quoted according to the equipment grade (such as the level of resolution, whether it was wireless, whether it had a video recorder, etc.), the brand, and the complexity of the project (such as the difficulty of the cable, the number of installation, etc.). The price of a single camera ranged from more than 100 to more than 1000. 3. ** Contract signing and advance payment ** - After the client confirmed the proposal and quoted price, both parties signed the construction contract, and the client paid the advance payment. ** II. Construction Stage ** 1. ** Wrapping Construction ** - If it is a comprehensive distribution project, it must be carried out in accordance with the relevant electrical installation engineering construction and acceptance specifications. For example, the monitoring/security/anti-theft/alarm system installation project must meet the specified requirements. For different cable needs, such as station cable, optical cable, network cable, telephone cable, etc., reasonable planning and construction should be carried out. - According to the site environment, determine the camera, power supply, data cable, etc., to ensure that the line is safe, neat, and does not affect the normal use. 2. ** Equipment installation ** - He installed the camera in a suitable position, such as nailing it to the wall. For the camera that needed to be fixed on the monitoring pole, the camera's support could be fixed on the monitoring pole with a spinning tail wire. During the installation process, you should pay attention to connecting the power cable and data cable of the camera. Some cameras also need to be installed with quick mounting plates, screws and other accessories. Some cameras may need to be installed with memory cards. - If other equipment is involved, such as the access control device, it must be installed firmly and not tilted. The main power supply cable should be directly connected to the power supply. It is strictly forbidden to use a power plug, and there must be an obvious monitoring mark. - The equipment installation related to the construction of the computer room, such as the installation of the cable in the computer room, the installation of the distribution frame, and the installation of the UPS power supply, should also be carried out in accordance with the corresponding specifications. 3. ** Equipment Testing ** - When installing the front-end equipment (such as cameras), the back-end equipment (such as video cameras, storage devices, etc.) could be tested. After the installation, they would conduct a comprehensive test and inspection to see if the monitoring equipment could operate correctly, including checking if the monitoring screen was clear, if it could be recorded normally, and if the remote monitoring function was available. ** 3. Inspection and post-maintenance ** 1. ** Customer acceptance ** - After the construction was completed, the customer would check and accept the monitoring installation effect to ensure that it met the expected requirements. 2. ** Remaining payment and maintenance ** - After the customer passed the acceptance, he would pay the remaining amount of the project. Some construction companies may also provide regular maintenance services to ensure the long-term stable operation of the monitoring system. Read more exciting novels for free
Security surveillance camera installation price
There were many ways to set the installation price of security surveillance cameras. For small and medium-sized security monitoring projects, it can be calculated by point; large and medium-sized projects can be calculated according to the percentage of the machine, generally about 20% - 30%, the more projects, the lower the proportion. When the local construction standards are not strict, a point should be between 300 - 400 yuan; when the construction technology is standardized and the auxiliary materials such as cables are good, it should not be less than 400 yuan; some projects with higher construction difficulty should be distributed below 500 yuan or even higher. The current national industry standard for camera installation was between 100 - 120 yuan, and 40 - 50 yuan for support installation. The manual lens also needed to include lens adjustment. The cable laying was different according to the type of wire diameter pipeline. Generally, the wire diameter was 150 - 250 yuan/100 meters. If it was too high (about 5 meters), the labor cost would be increased by 10% - 15%. High-rise residential buildings also needed to increase the upgrade fee. In addition, in Panlong District of Kunming, the installation price of cameras in shops, families, supermarkets, and residential areas was 456 yuan, and the parking lot system was 19876 yuan. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Fish pond installation surveillance camera selection
When installing surveillance cameras in fish ponds, the waterproof, dust-proof, and anti-pollution performance of the cameras should be considered. It was best to have infrared night vision to ensure night monitoring. The lens had to have enough clarity and a wide angle so that it could cover more areas. For example, the fluorite C5X intelligent dual-camera could output color video in low-light environments without the help of warm lights. It could avoid the defect that ordinary cameras could not see faces clearly at night, and could clearly record the physical characteristics of people. Moreover, when the fish pond set the warning range and detected that someone had crossed the border or intruded, the camera could automatically send out a sound and light alarm. In addition, cameras such as Hikvision's ds2cd2347g1lu and Dahua ipc-hfw2431t-zs- S2 could also automatically switch to black and white mode, and had infrared light sources to ensure the clarity of the night monitoring effect. At the same time, the exposure time and white balance of the lens could be set to maximize the night monitoring effect. <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>
Surveillance camera 12mm
He only mentioned that the "surveillance camera 12mm" was rather vague and did not know the specific content of the problem. If it was a surveillance camera with a 12mm lens, from the reference, the surveillance camera with a 12mm lens could monitor a distance of 50 meters. For example, there was a 1200-line security equipment infrared night vision surveillance camera, and a high-definition array camera was a 12mm lens. The reference price was 388. Different focal lengths would affect the field of view of the camera. The 12mm lens was a telephoto lens, suitable for long-distance shooting and able to see details in the distance. However, it might not be suitable for indoor surveillance. Usually, 2.8mm or 3.6mm lenses were chosen indoors. If it was outdoor monitoring and needed to monitor a long distance, a 12mm lens could be considered. At the same time, when choosing a surveillance camera, in addition to the lens, it was necessary to consider the networking method, the resolution, the video storage method, indoor and outdoor use, the power supply method, the voice intercom, and many other factors. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Pinhole camera installation
1. Confirm the installation location: To ensure the concealment of the miniature (pinhole) camera, you can choose a place that is not easy to be noticed, such as sockets, holes, mirrors, smoke detectors, under the lamp holder, above the ceiling, the exhaust vent of the air-conditioning, etc. If it is in the bedroom, it is also one of the choices. 2. Inspection before installation: check the size of the expansion plug and screw to confirm that the model is the same; deal with the pipeline interface to ensure that the cable is smooth. 3. Mount the lens: Mount the lens. Be careful not to let your hand touch the lens and make sure the CCTV is secure. 4. He connected the power source and turned on the main computer and the live surveillance cameras. 5. Adjusting the focal length of the aperture and adjusting the angle: adjust the angle of the camera to the desired range to ensure the best shooting effect. It should be reminded that in China, it is illegal to use a pinhole camera to secretly take photos and other acts that violate the privacy of others. The pinhole camera should be used in legal compliance, such as for legal home security surveillance (under the premise of informing the relevant personnel and not invading privacy) or legal surveillance scenes of enterprises. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Surveillance camera aperture means
In terms of concept, the aperture was a device in the surveillance camera that controlled the light passing through the lens and adjusted the light sensitivity inside the camera. In terms of structure, it was controlled by the amount of light passing through the lens. Usually, the F-value was used to express the size of the aperture. In daily life, 1.0, 1.2, or 1.4 would be used to represent the aperture size of the lens. When the F-value was smaller, the larger the aperture was, and the more light the sensor chip could pass through. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
