Ordinary waterproof cameras were surveillance cameras used for security purposes. They could restore high-quality, high-definition images and were waterproof. Under the technical framework, an ordinary waterproof camera could achieve the monitoring effect of several ordinary non-waterproof cameras. The monitoring coverage was wider, the image resolution was higher, and the amount of information was richer. This helped to reduce the scale of the system, reduce the complicated video image, control, and power supply transmission lines. It could also reduce the configuration of front and back equipment to reduce the overall construction cost, and promote the video surveillance system to be intensive and efficient. Ordinary waterproof cameras played an important role in road traffic command. They provided intuitive live images for the command center. The operator could fully understand the traffic and public security situation through large screens, computers, and other equipment. In the event of an emergency, they could watch the event process in real time and call the playback video. Its performance and image signal quality directly affected the real-time recording and monitoring effect of the system. Ordinary waterproof cameras have outstanding advantages such as long night vision, high quality, high definition, superior waterproof performance, and comprehensive performance stability. They occupy a large market share in night vision surveillance and are suitable for shopping malls, hotels, schools, communities, banks, enterprises, and other indoor and outdoor 24-hour surveillance sites. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The slow-motion camera mainly relied on the principle of high-frame-rate shooting. Normal video frames were usually 24 or 30 frames per second, but slow motion photography required a higher frame rate, such as 120 frames per second. When played at 30 frames per second, the picture would be slowed down by four times. In terms of equipment selection: - ** Cameras **: Many modern cameras and smart phones have high frame rate shooting functions. Some professional cameras can reach 1000 frames per second, and some high-end smart phones support 240 frames per second slow motion mode. When choosing a camera, besides considering the frame rate, one also had to consider the sensor size and image quality. - ** Lenses **: The choice of lens is also very important. The wide-angle lens can capture a wider scene, and the telephoto lens is suitable for shooting distant details. For slow-motion photography, it is recommended to use a large aperture lens to ensure that there is enough light for high-frame rate shooting, and to use a stabiliser or tripod to reduce the shaking and ensure the clarity of the picture. - ** Lighting **: Slow motion photography often requires more light because high frame rate photography reduces the exposure time of each frame. For indoor shooting, you can consider using professional lighting equipment or natural light sources. The high-speed camera could shoot high-speed moving objects (such as shells) with the help of a mirror. For example, when shooting the trajectory of the shell, a deflective reflective mirror could be used to reflect the movement of the shell into the high-speed camera lens. The camera remained still, and the rotation speed of the mirror could be obtained by calculating the flight speed of the shell, the angle of intersection, and the distance between the mirror and the shell. If the motion trajectory of the captured object is constantly shifting (such as playing table tennis), two mirrors can be used to do two-axis movement (X-axis and Y-axis). First, the horizontal image captured by the X-axis is reflected to the Y-axis, and then the Y-axis reflects the horizontal and vertical images to the camera to keep the image in the middle. Early tracking used non-optical motion capture (based on measuring inertia and mechanical motion), while modern optical motion capture tracked movement through software. AI artificial intelligence could identify object characteristics and simulate motion trajectories with computer controlled mirrors to better record high-speed moving objects. In addition, there were also some special camera equipment, such as the Pikfang Pet Short videos Self-made Machine, which had an automatic shooting function. Although it was not a specialized slow-motion camera, it also reflected the development and innovation of the camera equipment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera battery can be placed in a waterproof box. The camera battery was afraid of moisture, and the moisture box could effectively reduce the humidity, which could be used to store some precision instruments. However, the battery storage was particular. It could not be stored at full power or without power. The best remaining power of the lithium-ion battery was about 20%, and the temperature was best between 0 - 15 ° C. No matter what kind of battery it was, if it was not used for a year or half a year, it was best to charge it several times. In addition, when the camera was not in use, whether it was a lithium battery or a fifth battery, it had to be removed from the camera and stored separately. In particular, disposable batteries could not be placed in the camera for a long time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The motion detection camera algorithm was usually based on the images collected by the camera at different frame rates, and the CPU calculated and compared them according to a certain algorithm. When there was a change in the image, such as someone walking by or the camera being moved, the corresponding operation would be triggered when the calculation result exceeded the predetermined range. Take the Kazuki camera as an example. The image captured by the camera was processed by the CPU algorithm. When the image was different from the image captured a second ago, the system automatically prompted an alarm. If a moving object was detected, the camera would turn on the recording function and push the alarm message to the phone. The PIS motion detection technology was based on the principle that objects above absolute zero emit infrared radiation. When a heat source such as a human body enters the detection range of the PIS sensor, the thermal element in the sensor senses the change in infrared radiation and transforms it into an electrical signal. After amplification, filtering, and comparison processing, it triggers an alarm or recording mechanism. It uses the difference between the current image and the background image to detect moving areas, but it is sensitive to dynamic scene changes such as lighting and external interference. In addition, there was also a motion detection energy-saving method based on the image comparison algorithm disclosed by Zhengyuan Wisdom, which included the steps of activating the motion detection device when the human body or the vehicle body entered the sensing range of the human body proximity sensor, assisting the camera unit to shoot through the lighting unit, transmitting the image to the external host for division, marking, and other operations. Finally, the image in the memory was finally processed by the computing processor using the image comparison algorithm and stored in the memory. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
If the motion camera is shaky, you can use the following methods to solve it: * * 1. The camera's own anti-shake technology ** 1. * * Image Stabilizer (CCTV)** - The principle was to place the CCDs on a stand that could move up, down, left, and right. First, it detected the shaking situation, including the direction, speed, and movement of the shaking. Then, it processed the detection signal to calculate the amount of movement of the CCD-based camera that could offset the shaking. Then, it used the mechanical movement inside the camera to compensate for the hand shaking to achieve anti-shake. 2. * * Image stabilization ** - It was to offset the vibration by moving the lens horizontally or vertically. The longer the focal length of the lens, the better the anti-shake effect of the lens. In low light conditions, the anti-shake effect of the lens can also perform better because it can be used as an independent working unit without affecting the focus and dimming system of the camera sensor. However, lens anti-shake could only reduce the shaking when shooting with a hand-held camera, but it could not completely eliminate it. It might not be effective or even counterproductive when shooting special scenes such as shooting birds, long exposure, stacking, etc. 3. * * Five-axis anti-shake (Take Oppo as an example)** - It can achieve anti-shake operations such as pitch, swing, horizontal translation, vertical translation, and rotation in a narrow body space. The maximum anti-shake range of horizontal translation and vertical translation can reach +3 °. Technically, it used software algorithms to distribute the split shake data to the two moving components of the lens and sensor, and then used a motor or memory metal to drive the lens or sensor to produce displacement to achieve anti-shake. This anti-shake technology improved the OIS anti-shake ability of conventional lenses by 65%, and the anti-shake accuracy was increased to 3.5 times. When capturing motion images such as skateboarding, it could make the image stable and the details of the character's movements rich. In dark scenes, it could also be used with self-developed algorithms to achieve the ultimate image. * * 2. Borrowing external equipment ** 1. * * Holding the Cloud Platform ** - For example, a hand-held cloud head like the Okugawa Smart XI had a three-axis anti-shake function. It also had the functions of switching between horizontal and vertical screens, remote shooting with gestures, and zooming with silk-smooth focus. Through the mechanical structure and electronic control of the cloud head itself, it stabilized the lens during sports shooting and reduced the lens shake caused by hand-held shaking. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The tutorial for shooting slow motion with different equipment is as follows: 1. ** Some Xiaomi phones **: Turn on the camera, click on the top right corner to enter the camera settings, customize the camera function layout, and press and drag the icon to adjust the layout to achieve slow motion shooting. 2. ** Osmo Pocket Pocket Cloud Platform camera, Osmo Action camera, Osmo Mobile phone cloud platform 3, Dajiang drone Mavic Mavic 2 and Mavic Air**: connect the device to the phone, and then operate it in the DJI Mimo App interface to take a slow motion effect. 3. ** Using AI (Take Huawe-related technology as an example)**: - First, the frame information and event information captured by the two cameras were sent to the warping and synthesizing modules. The warping module used the U-shaped network to convert the motion into optical flow representation, and then converted the events into real frames; the synthesis module used the U-shaped network to place the events between two frames and directly generate a new possible frame for each event. - Since the synthesized video might have noise, the third module would use the new information in the second intercept synthesis module to refine the first module, which was to extract the most valuable information from the two generated frames of the same event and perform warping optimization (again using the U-net network to generate the third frame version of the event). - Finally, these three candidate frames were input into an attention-based average module, which used the best part of the three frame representation to form the final frame. Repeating this process for all the events provided by the event camera would produce the final desired result. 4. ** Computer (using PR or FCPX software)**: import the captured footage into the software and change the speed of a certain area of the footage to achieve a slow-motion effect. 5. ** General camera equipment **: - ** Device Selection **: - ** Cameras **: Many modern DSLR cameras and mirrorless cameras support high frame rate shooting, such as the SonyA7S series and Canon Eos R series, which can shoot 1080p or 4K video at high frame rates. Professional cameras such as the SonyFS7 and the Red series can provide higher frame rates and better picture quality, but the price is relatively higher. - ** Lenses **: Fast lenses can perform better in low-light environments, wide-angle lenses are suitable for capturing vast scenes, and telephoto lenses are suitable for capturing distant details. - ** Tripod and Stabilizer **: When shooting in slow motion, stability is very important. Using a tripod can ensure the stability of the camera and avoid blurring the picture due to shaking. - ** Principle **: By shooting a video at a high frame rate (such as 60fps, 120fps, 240fps, or even higher, the standard frame rate for movies is 24 frames per second), and then playing it back at a normal speed during playback, time can be slowed down to capture more detailed movements. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
