Considering the choice of IP
cameras, it should be noted that, in spite of their diversity, a
single universal device ideally suited for any conditions at the moment does
not exist. The choice of each chamber is carried out in accordance with
the conditions under which it will operate, and the challenges that will be
addressed. The latter include video surveillance: the perimeter, in the
office, identification numbers of the machine, etc.
Also, when selecting data cells, it should be guided by
the principle of price - quality. Considering the question of the camera,
it may be noted that the primary indicators are: reliability, image quality,
stability, video encoding and assembly. In some cases, also provide
stability and opportunities, and of course price. The defining characteristics
of the IP camera images are as follows: the quality of the encoder, the lens
and the image sensor "CM". BTW, you can buy the cheap mini camera at Banggood. Besides, you can easily get other electronic
accessories (e.g. tubular lock pick for sale) there with high quality and reasonable prices.
Of course the picture quality
"CM" depends on the resolution, color, sensitivity, signal / noise
ratio, etc. Matrix used now has such a unit to expand:
- Standard, which is defined in this standard PAL 720x576, or 640x480 is;
- Megapixel - 1, 1.3, 2, 3.5 megapixels, etc.
Large image detail, of course, is acquired
in the presence of a higher resolution. Now the number of megapixel
cameras is growing rapidly and subject to the continuation of this trend will
soon exceed the amount produced by the standard resolution cameras. This
is because the weight of megapixel cameras has a number of advantages in image
quality issues.
Finally, you can go to the main qualities
of IP cameras, namely stability. Damage mechanics of IP cameras is quite rare,
and it is often associated with installation errors or mechanical damage. But
in contrast, the problem of “hovering” IP cameras attracts attention. After
all, it is they and software is critical to the reliability of video
surveillance systems. Each IP camera has a processor and its operating system,
which controls the camera, in fact, a computer. Like any other computer,
IP camera can "hang" or become unstable.
