Can the wireless wifi surveillance camera be monitored remotely?

Yes, the operation process depends on the details.

I. Functions of the system

Remote real-time monitoring function users can use the monitoring client software to watch remote monitoring videos in real time through the Internet. The monitoring client software can be installed on computers and smart phones.

2. Remote alarm and remote fortification removal function

The wireless camera of the home wireless remote monitoring system can monitor the images within the range of15m, and send the alarm information to the user's mobile phone and client software at the first time. Users can use computer or mobile phone client software to defend and disarm the monitoring site remotely and conveniently.

3. Network storage mirror function

The home wireless video monitoring system can save the monitoring video through the network. In the state of no alarm or disarming, the video of the monitoring place can be stored on the network hard disk at regular intervals; When an alarm occurs, the image can be continuously saved on the network hard disk until the alarm is lifted. Users can watch the monitoring video playback at any time through the client software.

4. With night vision, pan/tilt and other case control functions.

Choose a wireless camera with infrared night vision function to shoot normally in the absence of light. If you use a 360-degree rotary pan/tilt, you can also greatly expand the monitoring range, avoid monitoring dead ends, and let one camera achieve the use effect of multiple cameras.

5. Mobile phone interactive monitoring function

Mobile phone is the most mobile monitoring tool, and powerful monitoring client software can be installed on smart phones, while ordinary non-smart phones can easily browse real-time and historical monitoring images by using the browser on their mobile phones. When an alarm occurs, the mobile phone will receive a short message with a link to the monitoring image, and the user can directly open the monitoring image in the short message. Users who are not used to using mobile browsers can also send SMS to the service number, and the system will automatically reply to the SMS linked to the current picture. Users can open the monitoring screen in short messages, and at the same time, they can also use short messages for operations such as disarmament.

Second, the system composition

The system consists of wireless router or wireless AP, wireless camera, modem, power supply, network hard disk video recorder, audible and visual alarm, computer terminal and other devices. If the system needs anti-theft detection function, you can choose to use network W hard disk video recorder (NVR), and use network NVR for moving image detection, anti-theft protection and automatic video recording.

Third, equipment selection

1. Selection of wireless remote monitoring camera

There are two kinds of wireless remote monitoring cameras in the market, one is WIFI wireless camera, and the other is 3G wireless camera. These two cameras have their own characteristics. WIFI wireless network camera is cheap, mature technology, and does not need wiring when installing. It is more convenient to install and add more cameras, and the cost of surfing the Internet is lower. The disadvantage is that the WIFI wireless network camera can only be used normally after doing some simple network configuration according to the instructions. At the same time, the distance from the webcam to the wireless router is generally required to be within 30- 100 meters. If it exceeds this range, you need to use a dedicated antenna or install a wireless router nearby. At the same time, where wireless routers are used intensively, it is necessary to set up a wireless router for a long time. 3G network cameras are 1U-SUJMA, WCDMA, CDMA2000, and corresponding mobile phone cards need to be inserted into the cameras. Advantages of using 3G network camera: simple to use and can be used without any configuration; There is no need for wiring, self-built heat meter or any network, built-in lithium battery, and it can be used anywhere with mobile phone network. But it is expensive, and the later use cost is high.

Considering the mature technology, low price and low later use cost of WIFI wireless remote camera, this paper chooses WIFI wireless camera as the system component. On WIFI day, the wireless camera is equipped with CPU and WEB operating system. Through the Web browser, you can remotely access and view the real-time images of network cameras, allowing administrators to manage and control network cameras anytime and anywhere. There are several applications that can realize image monitoring, image recording, snapshot and other functions, including pictures of up to 32 cameras. When choosing a WIFI wireless camera, you need to consider the following factors.

The first is the size and weight of the equipment. Lightweight and compact equipment is easy to install and hide, which is the best choice for safety monitoring. When installing the equipment, it can be fixed on the ceiling, partition wall or glued to household appliances without tools. Medium-sized camera with base or bracket is cheap, but it must be installed with electric hammer or electric drill and fixed on the wall with expansion bolt, which is inconvenient to hide and complicated to install, and is not recommended. Secondly, the choice of night vision function requires an infrared auxiliary light source, which is slightly expensive, but it is the best for anti-theft detection.

Thirdly, the choice of brand, home security wireless camera is best to choose the products of network manufacturers, although the monitoring effect is not as good as that of professional image manufacturers, but it is simple to use, simple to configure and convenient to surf the Internet.

Finally, the requirement of image clarity, the resolution of high-definition network camera is 640x480, which can basically meet the needs of daily monitoring, and the price is low, which is the mainstream of the market. 720P or 1080P high-definition cameras have good monitoring effect and clear images, but the price is more than twice that of standard cameras, and the requirements for routers and network bandwidth are higher, so they have not been popularized.

2. Selection of wireless router

Wireless router is a necessary wireless product for ordinary families, which is cheap and easy to use. However, because remote monitoring requires a lot of data flow, and the transmission power of home wireless cameras is relatively low, it is best to use relatively high transmission power, and the CPU frequency is above 434MHz. There are more than 64 million wireless mountaineers in memory.

3. The choice of hard disk video recorder

If the home wireless video surveillance system is used for burglar alarm at the same time, it is better to add a network hard disk video recorder (NVR) to connect people to the wireless router kernel as the host for video motion detection, burglar protection and video recording. If the purpose of the system is only to take care of the elderly and children or watch pets, there is no need to use a hard disk video recorder.
