How to use a webcam

Question 1: How to use the HD webcam 1. equipment installation

1. Connect the webcam to your network, or connect it directly to the PC using a crossover cable.

2. Connect DC 12V power supply.

3. Under normal network connection, the connection light (orange) at the network interface will light up within 5 seconds, the data indicator light (green) will flash, and the physical connection of the network camera is completed.

Second, the preparatory work

1) The IP address of each webcam is192.168.1.19, and the subnet mask is 255.255.255.0. The IP address of the network camera can be modified, for example, the IP address of the network camera is changed to192.36089.36666666, and the IP address of your computer is changed to the same network segment as the network camera with the same subnet mask. Such as:192.168.1.171.

2) Test whether the network camera is started normally. Open a command line window according to the operation in WINDOWS, and enter ping192.168.1.19 in the command line window. If "Request Timeout" is not displayed, it means that the startup is normal;

3) when using Internet Explore to access the network camera for the first time, you must temporarily lower the security settings so that ActiveX components can be installed in the network at one time, and select tools Internet options-security-custom level -àActiveX controls and plug-ins from the browse menu >, set the security level to low, and then click reset.

Question 2: How to use the HD webcam? The network camera can be directly connected to the computer through the network cable. First find the ip address, user name and password on the camera body, and then modify the ip address of the computer to the same network segment of the camera. Open ie browser again, enter the ip address of the camera, prompt to install the plug-in, press enter after installation, and then enter the user name and password, and you can see the real-time picture.

On NvR, first change the ip of NVR to the same network as the camera, and then connect them together with a switch to add the camera to NVR.

Question 3: How to operate the network camera to connect to the network Steps 1: Turn on the network camera and connect it to your router or switch with a network cable.

Step 2: Under the same LAN, use the computer to open the camera search tool that comes with the camera, search the IP of the camera, and change the IP to the same network segment as your computer.

Step 3: Enter the IP of the camera you found or changed with the camera search tool in the IE address bar, log in to the camera in the local area network, enter the camera settings page, and set relevant network options (generally default). If the camera has WIFI function, enter the WIFI setting page to set wireless, otherwise ignore it;

Step 3: Log in to your route and check whether your route settings have black/white list settings. Cameras must be allowed to surf the internet here.

Step 4: Early cameras need to log in to the router to map network ports and have certain network knowledge. Products produced after 20 14 generally do not need this step and can be ignored.

Step 5: Install the camera APP with a mobile phone with Internet access, open the APP, and enter the camera account and password for remote access; If you need a computer to remotely access the camera, you can install software like a mobile phone, add a camera, and enter an account password.

At present, the networking and access steps of webcams on the market are basically the same as above.

The above manual tapping, if it helps you, please remember to adopt it in time. Your adoption is to help your netizens enthusiastically.

Full affirmation and respect.

Question 4: What is the webcam for? Network camera is a new generation camera which combines traditional camera and network technology. It can transmit images to the other side of the earth through the network, and remote viewers can monitor their own images only by a standard web browser (such as "Microsoft IE or Netscape") without using any professional software. The webcam has embedded chips and uses an embedded real-time operating system.

Broadband information network can not only provide high-speed network access, but also replace copper cable image transmission lines, and bring real-time image monitoring into the application scope of broadband information network, which makes it inevitable for information network to replace traditional closed-circuit television. The multimedia monitoring system based on PC is powerful, but it mainly carries out small-scale monitoring. When the transmission distance is long or the internet is needed, the multimedia monitoring based on PC is not stable enough, consumes high power, needs someone to be on duty, and the software is not open. These problems provide a stage for network video monitoring based on network and embedded technology.

The network camera converts images into data packets based on TCP/IP network standards, so that the images taken by the camera can be directly transmitted to the network through RJ-45 Ethernet interface or WIFI WLAN wireless interface, and the images can be monitored remotely through the network.

The network camera adopts the most advanced camera technology and network technology, and has powerful functions. The built-in system software can realize real plug and play, allowing users to avoid complex network configuration; Built-in large-capacity memory stores the image before the alarm is triggered; Built-in I/O port and communication port are convenient for expanding external peripheral devices such as access control system, infrared sensor and omni-directional pan/tilt. Provide software packages (SDK) for users to quickly develop application software.

Panasonic network cameras are widely used in education, business, medical care, public utilities and other fields.

Question 5: How do network cameras record with computers? Network cameras have this function, as long as they can be connected, they can record. At the same time, video recording is also possible, just set it in the background management software.

Question 6: How to connect the network camera with optical fiber? Hello, landlord.

Network camera is a kind of network equipment. According to what you listed, there are two routing methods:

1, n network camera-network switch-optical fiber transceiver-optical fiber transceiver-switch-network hard disk video recorder-display.

2.n Network camera-multi-network optical transceiver-optical fiber-multi-network optical transceiver-network switch-network hard disk video recorder-display.

Optical transceiver or optical fiber transceiver has network port and optical fiber connector (FC, ST, FT, etc. ). The network port is connected with network cable equipment, such as webcam and switch, and the optical fiber connector is connected with optical fiber.

Question 7: How to use the network camera to connect the mobile phone to turn on the camera's Shadow Cloud function, and then register users and add devices in Shadow Cloud official website. After installing the timely cloud client on the mobile phone, it can be monitored remotely.

Question 8: How to use the wireless webcam? Plug in the power supply and memory card (for storing video) and connect the network camera with the network cable, and set up the network and wifi on the computer. If it's the first time to use the wireless webcam, it's not needed after it's set up, and it will automatically connect to wifi in the future. However, the wireless camera takes up a lot of network, and the network will be very stuck if it is slightly worse. It is recommended to use a network cable, which is relatively stable. For example, the four red lines can be used, and their home can be installed with monitoring only by network cable. They can install it themselves. It's simple. I use their products in my own home, which is very good. You can have a look if you need it.

Question 9: Teach how to use the camera 1. The camera must be steady.

Stability is the first element that photographers should keep in mind. The stable picture gives people a kind of safe, true and beautiful enjoyment, which makes people feel very comfortable. If the picture is unstable, then the whole picture will shake from side to side, making people unable to see the subject clearly and it is difficult to understand your shooting intention. Moreover, the picture is dazzling, has psychological influence, makes people upset and very anxious. I won't explain this psychologically, just think about it. An object jumps before your eyes. Want to see clearly, but can't see clearly, will the mood be good? Therefore, keeping the picture consistent and stable is the first prerequisite for shooting. Whether shooting, such as pushing, pulling, shaking, moving, leaning, tilting and zooming, we always work around how to keep the picture stable, so as to shoot good materials. To sum up, maintaining the stability of the picture can be well solved from three aspects:

1. Use tripod resolutely if conditions permit.

Using a tripod is the simplest and best way to keep the picture stable. In fact, TV stations will use tripods whether shooting TV series or shooting parties, because it can keep the picture stable to the greatest extent. Some people will say that TV stations are stable in shooting news without tripod, but that's because TV cameramen are professionals with strong basic skills, and they all use shoulder cameras. Our ordinary camera lovers all use small machines, and their basic skills are very different. Therefore, to keep the picture highly stable, using a tripod is the safest way. Here, I suggest that camera enthusiasts buy those portable tripods, which are not only convenient to carry, but also can break through the environmental restrictions and be used in various occasions.

2. Keep the correct shooting posture

Correct shooting posture includes correct camera holding posture and correct shooting posture. There is no fixed mode for holding the camera, which varies from camera to camera, but generally, when opening the viewfinder, you must hold the viewfinder with your left hand, otherwise it will easily cause the camera to shake.

Shooting postures mainly include standing posture shooting and kneeling posture shooting: when shooting in standing posture, hold the camera tightly with both hands, relax your shoulders, press your right elbow to your side, and lift the camera to a position slightly higher than your chest. Hold the camera with your left hand to help stabilize the camera, and take a comfortable and stable posture to ensure that the camera is stable. Legs are naturally separated, about shoulder width, toes slightly outward, stand firm and keep balance. When shaking, the lifting frame should be placed in an uncomfortable position, and the picture on the left should be placed in a comfortable position. Try to keep your feet still when possible.

When shooting in kneeling position, the left knee touches the ground, the right elbow rests on the right knee, and the left hand also holds the camera, which can obtain the best stability. You can also use local materials at the shooting site to support and stabilize the body and machine with the help of stones, railings, trunks, walls and other fixtures. Correct posture is not only conducive to operating the machine, but also can avoid the fatigue caused by long-term shooting. If you shake the camera again, you will shake it from an uncomfortable position to a comfortable position. It is also important to note that don't be clever and avoid shooting around with the machine in one hand, or shooting while walking.

3. Practice basic shooting skills.

Practicing basic skills will provide better guarantee for your shooting effect, not only improve your shooting stability, but also improve all aspects of quality, and you will benefit from the improvement of basic skills. One of the basic exercises is to shoot more, and the other is to watch more, see what others or TV pictures look like, and learn more. In short, when practicing basic skills, you are not required to practice three or nine in winter and three in summer. Just pay more attention to accumulation.

2. Learning composition is the key to improve photography.

Like painting and photography, photography is also an artistic technique. The key is the bright lines and the harmony of the picture. A good composition not only makes people feel that the theme is clear, but also gives people a visual and psychological impact. A failed composition will make people think that the material you shot is messy. Therefore, to improve the level of photography, we must start with the link of building a good map. We should start from the following aspects:

1. Rational use of far, all, middle, near and specialized.

There are several kinds of camera framing, and the viewing angle of the picture changes from maximum to minimum. Foresight is generally to pull the camera lens to the maximum, and your camera can reach the maximum range that the camera can reach. Generally used when performing grand scenes, mainly for people to use when they are magnificent and huge. Panorama generally refers to showing the whole picture of a thing to everyone, such as taking a panoramic photo of a person, that is, taking all the people in the camera from head to toe ... >; & gt
