Network cameras or the mainstream of the surveillance industry

With more and more sites using webcams today, this article provides a simple overview of all aspects of digital network cameras, such as its advantages and disadvantages, installation methods, software use, remote operation, LAN operation and so on. I hope to let you know.

Network Camera, another name is called IPC (IP camera), it can not be used without network cable, so it needs a computer or network recorder NVR as a back-end storage device support. The first thing we want to say is its merits, why it will become the mainstream of the monitoring industry, even those who do not know the network application of the engineering operators to use it? Today's social science and technology development is very rapid, the prevalence of computer development is only more than 10 years. The IPC, by its overwhelming superiority, is unique Ngau tau. What we are most interested in is the ultra-strong picture quality, the exquisite clarity. And that's enough to beat the slightly cumbersome network operation.

Network Camera Benefits

Network Camera Many people call it Digital HD camera, which is different from the simulated imaging mode. Digital HD, is to convert the image signal to a digital signal, the formation of a pixel to present. There are usually 720p, 960p, 1080p. In pixels, it usually becomes 1.3 million pixels, 2 million pixels, 3 million pixels, and so on. For now, digital cameras can achieve ultra-high resolution of 3 million megapixels. The digital hemisphere is up to 2 million megapixels.

It is said that digital camera imaging is clear, in fact, the use of high-definition network chips and high-definition lens results. In fact, the quality of surveillance cameras in addition to their own program design, the lens also has a part of the reason, the lens of the grinding accuracy, material and purity and its coating process will affect the image color and texture. and the network digital camera lens whether in the work, or in the coating is very good, so it will have a higher light transmittance and focus, so it presents the screen is not comparable to the network camera. It is because of its high-definition picture, can let us see more clearly, and even with 20 meters away from the small print can be clearly read out. If the network HD ball machine, the clarity will be higher.

Another advantage of the network surveillance camera is that it is easy to install. As long as a power and network cable is enough, and the simulator needs to make a BNC video connector, and if we are doing a large project, the use of the camera has dozens of, but also need to be the hard disk recorder DVR back panel video input terminals one by one, so the operation is very troublesome, but with the network camera, No matter how many points you have in the previous paragraph, or the probe. Back end as long as a cable into the network DVR NVR can be.

Insufficient network cameras

All things are advantageous must have the disadvantage, this is a natural law, the digital camera's high definition lets everybody praise, its ultra simple installment way also lets everybody be satisfied, but although so still has the insufficient place, the first time monitors the picture the delay nature. Because the transmission of the screen is using the network, there will be some delay, some serious will enlarge this time to 3-5 seconds. While some small delays do not bother us much, they may be counterproductive if used in special places.

2nd, its transmission distance is limited, the use of network cable transmission signal can theoretically increase to 200 meters distance, but in fact, the transmission of network cable signal reached 150 meters is already the limit, and if it is high-stream Network Camera 100 meters will appear signal instability phenomenon, If there are more than one camera within the same LAN, it is common to lose the signal to each other. The other is the night vision effect, night vision effect is very important, but the digital HD camera in this area is somewhat inadequate, need to cooperate with the light to strengthen the light to be able to make a reasonable

No matter what the shortcomings of the network camera, but eventually will be ignored, the shortcomings can always be overcome and corrected, but we can not ignore is that it brings people the convenience and predict the development and progress of science and technology, I believe in the future is still the field of digital cameras, but at that time its technology will be more advanced, All aspects of the performance will be more perfect!
