[ Huaqiang Security Network News ] Network camera is a kind of equipment that comes into being based on the combination of network technology and traditional cameras. What kind of advantages does it have for everyone to buy and use? The following ten points are carefully compiled by the security investment network, and I hope to help you with your use needs. 
First, the network surveillance camera ends the problem of interlaced scanning;
Second, as a network monitoring system, everyone needs to carry out integrated wiring, which involves a network power supply problem;
Third, the current analog camera due to physical limitations, the image can only reach about 400,000 pixels, about 704 × 576; network cameras can easily do 5 million pixels, or even higher;
Fourth, it is a big selling point for network cameras and monitoring systems. Some network cameras have their own analysis functions;
Fifth, the network monitoring system integrates PTZ, P is a horizontal action, T is a vertical action, and Z is a zoom-in and zoom-out of the lens;
Sixth, the network camera not only transmits the video, power signal, and PTZ control signals through the network cable, but also intercepts the audio. The audio can also be transmitted through the network data line, and can be one-way, two-way, and reverse.
Seventh, network information security has been improved;
Eighth, the network video surveillance system provides a flexible system expansion space;
Ninth, the network camera system is a true digital solution;
Tenth, lower overall cost.
2. Working principle of led solar wall light
In addition to the components of traditional wall lights, solar led wall lights also have components that traditional wall lights do not have, such as solar panels, controllers, and batteries. Its specific working principle is as follows: during the day, when the sun shines on the solar cell, the solar panel will convert the thermal energy generated by the light radiation into electrical energy, and the battery will be charged and stored through the charge controller. When the night comes, the controller will control the discharge of the battery to meet the needs of night lighting.
3. Features of solar powered led wall light
1. The primary feature of the solar wall lamp is that it can be charged automatically. When the sun shines during the day, the solar wall lamp can use its own components to convert light energy into electricity and store the electricity, which is impossible for traditional wall lamps.
2. Solar wall lights are generally controlled by intelligent switches, and they are automatically turned on by light control. Usually it will automatically turn off during the day and automatically turn on at night.
3. Since the solar wall lamp is driven by solar energy, it does not need an external power supply or complicated wiring, and the work is very stable and reliable.
4. Ultra-long service life, the solar wall lamp uses semiconductor chips to emit light without filament. Under normal use, the lifespan can reach 50,000 hours, compared to 1,000 hours for incandescent lamps and 8,000 hours for energy-saving lamps. Solar wall lights can be said to be very long-lived.
5. We know that ordinary lamps and lanterns contain two elements, mercury and xenon. The used lamps and lanterns after use will cause great pollution to the environment. But the solar wall lamp is different. It does not contain the two elements of mercury and xenon, so the waste solar wall lamp will basically not cause environmental pollution.
6. Health. The light of the solar wall lamp does not contain ultraviolet rays and infrared rays, and this kind of light will not cause harm to the human eyes even if it is in contact for a long time.

Led solar wall lights have the following advantages:
1. Definition of solar wall light
The led solar wall lihgt is a kind of lamp that utilizes solar energy to generate electricity, store energy, use electricity and lighting, and has a fully automatic control system. It is no different from the traditional wall lamp in appearance, and also includes basic structures such as lampshade, light bulb, base, etc., but in addition to these, it also includes important components such as solar cell components and automatic controllers.2.

7. Safety. The output power of the solar wall light is completely determined by the solar battery pack, while the output of the Tianyang solar battery pack depends on the temperature of the solar surface, that is, the intensity of the sun. The standard output of solar cells per square meter is about 120 W. Considering the panel area of the solar wall lamp, it can be said that its output voltage is very low, and it is an absolutely safe light.
