Zexon Lens
how to know Zexon Lens:
zexon CCTV lenses are classified based on the mechanism and type
of use:
1. Lenses fix
01.01. Lenses fix industry
01.02. Lenses fix mini camera
2. Lenses, varifocal (variable focal length)
3. Lenses motorize (motor)
One of the most important parts of designing a zexon CCTV and network camera system is a type of lens.
As noted by light ccd lens And develope network camera has been converted into
electrical pulses (0 or -12 v) and delivered to monitoring server, server
monitoring for a specific protocol, such as pulses and converted back to image
and displays.
If appropriate light Ccd
Nature can not fail to give a good picture of it from a lens with an
image of poor quality will not use.
Assume a very high resolution camera is extremely
professional when sufficient light from the ccd Lnzbh Without guidance, published ccd not a good
picture because of the light that passes through the lens and if it is
inappropriate ccd lens properties, failure, and how it has changed and
therefore the transmitted light ccd On
the basis of incorrect entries, it sends the wrong image.
After selecting the proper lens comes to choosing the right
lens quality and efficient in terms of angle and depth of vision is one of the
things that are important in choosing a lens choosing the proper focal length
lens with a focal length of the lens because of the angle and Whatever the
number is, the depth of the lens (mm focal length) is greater than the depth of
the lens is smaller than angle lens.
According to this perspective, are inversely proportional to
the depth of vision, the angle is less than the depth of vision and depth
vision comes from the lower angle is higher.
It is a top choice lens, wide angle of view not because deep
down in the same way lens and tele (lenses with focal high) Top view of the
depth.
In every lens there is a section called ip camera that the light
passing through the lens (in different environments and times of day) is. In
some lenses, to be regulated automatically (Auto iris) Vdvrbyn that this
series will be able to use the lens at all hours of the day, the server can
send a clear picture by of the ideal. In some Yryz to manually adjust the
lens Is (manual iris) and a series of
cameras that use lenses in only be able to provide a clear picture of Optic that it has been adjusted and changed according to the changes of illumination,
image outside of normal It is.
Zexon Camera ip Surveillance fixed lens
They are completely fixed focal length lens and a fixed
focal depth and angle due to the well established ones. These lenses are
denoted by a number in millimeters. For example, 2.8 mm fixed lens and the
focal length as noted above (2.8 mm), indicates the viewing angle (about 150
degrees) and depth of vision (about 8 m).
It has a fixed lens (board mount, cs mount) when they select
the proper angle and depth of vision is very clear.
Zexon Camera ip Surveillance varifocal lenses (variable
focal distance)
This Zexon lens has a variable focal distance and a variable
focal length due to the angle of view and depth intervals with variable focal
length lenses generally have two focal series are introduced.
For example, the lens
5 ~ 50 to 50mm is the focal length of 5mm.
Zexon Varifocal lens with a focal length of all primary and
secondary focal length of a lens is the distance between the two lenses of the
same show.
When we say the focal length of the lens 5 ~ 50 5 mm to 50
mm adjustable and is adjusted so that it is relatively common but mistaken Vqy
The lens is 50 miles away up to 1 meter 50 mm is almost.
But actually it is not,
Based on a series of calculations, a distance of 50 meters from the
distant 20/1 Show more understanding but because of the ease of lens and lens
selection that they give away at a distance of 1 meter to 50 meters. In
summary, the lower is the formula for calculating.
Magnification = focal length / distance
It is due to hand (manual) focal length of the network
camera lens varifocal, and the selection
and arrangement of the lens changes the focal length with a fixed focal length
lens into a convenient and efficient are set to change the focal distance the
user manual (only) the possibility that the effective focal length so (see the
appropriate angle and depth) at predetermined intervals and set the lens
selection.
The network ip camera varifocal lens is one of two levers
shift levers of the second lens (focal length) and the other lever to adjust
the distance between the first lens to ccd (the clarity of the image) is.
Varifocal lens with auto focus was not short of any changes in the location of
the two lenses (focal length) is also a need to change the location of the
first lens (manual focus).
When the lenses are selected during the initial design to
choose exactly the right angle and depth have not been seen in the state of
nature can not be the appropriate focal length. (Can not be used to fix a
lens), the focal distance is required to select a range of focal, varifocal
lens which provide the users are in this range.
camera IP lenses motorize
These lenses change the location of the lens and the focal
length of the lens (change magnification, angle of view and depth) and
resolution varifocal lenses are exactly the same except that the focal distance
with a remote control device or by the motor will change and shift lens first
lens for image clarity and transparency is fully automated and intelligent.
Lenses, varifocal lens with two focal generally motorize mm are introduced. And
commercial modes as well as a number x are also shown. For example, the lens
motorize 34x power zoom lens, which
represents the number assigned to the initial focal length lens (at wide) focal
length of the final lens (at tele) is.
The magnification of the lens motorize [exactly the same
lenses, varifocal] among the laymen of the business and is calculated by the
following formula.
Magnification = focal length / distance
This calculation is based on the maximum focal length of the
lens motorize the more common are:
(The distance of the object to the camera) zoom = distance /
maximum focal length
It network camera motorize lenses are virtually obsolete due
to the fact that when the lens is at tele mode (maximum focal length of the
first lens and the second lens at the farthest) point of view is very limited
to compensate the lack of cover environment need to move the camera and use a
rotating basis and due to obsolescence and increasing revolving basis, a
complete set of final price (motorize + camera + lens cover out door + fan +
base + neck + heater control unit)
These lenses are rarely used (except in very special circumstances).
And now the zexon network camera ip Speed trap (we will discuss in detail
the relevant chapter) set are replaced by the addition of extra features (high
speed rotation, careful planning and professional capability, allowing
connection of sensors, etc) with fantastic prices The lower Are.

The benefits of zexon tech CCTV network:
In this paper we define the CCTV network, and the advantages
and disadvantages of this type of camera will be reviewed. It is a
network-based information to better understand the background of this paper.
The hardware structure of the network cameras or analog
cameras and IP Camera is somewhat similar with the exception that the module is
equipped with a network of cameras, digital video and images to be transmitted
on the LAN medium. There is also the ability of processors to compress and
optimize images the camera is. Need to remember is that these facilities are
located in analog systems on the DVR. Some cameras also have a special
processor to store images on the internal memory or external SD RAM are like.
The advantage is that it eliminates the image capture device is a special
purpose.
There are modules that each camera can cause the camera
network IP address is the unique network and an independent component in the
network send and could get Decrees.
The benefits of zexon tech CCTV network:
In many projects, video surveillance, zexon IP or analog
systems most difficult choices ahead. Type of infrastructure, amenities and
price, IP cameras and analog CCTV system design are very different
understanding of the project requirements and the characteristics of each of
these solutions must be the best and most affordable way.
Here are ten advantage of using a zexon camera network has
been introduced to account for the large projects:
- High resolution in zexon tech camera :
Zexon Analog cameras, zexon network cameras, the image
quality will not limitation. A 5-megapixel IP camera can provide 10 times
greater than an analog camera's image quality is 4CIF.
Analog cameras feature 704 x 480 pixels and up to 29
megapixel network cameras are available. Some thought that this would only
further improve the quality of image resolution are required to mention the
fact that the quality of the image that the wider range reduce the need to the
number of cameras high are.
- Ease of installation:
Zexon IP cameras can easily be connected to existing
networks in each set. The camera for image data transmission and power supply
cable need only one.
If there is a computer network cabling to the cameras no
longer need to set the PoE power requirements of the camera from the network
cable to provide.
Some IP cameras also feature a special manner that can be
remotely adjusted via the network cable to it. Features such as zoom
adjustment, adjust the focus and selection of the image pixels can be done via
cable.
- Being fully digital:
Unlike an analog CCTV camera,zexon technology IP camera
images of moving long distances or converted to other formats with no loss of
quality. A network camera can stream or record images to view different offer.
IP cameras can also select a specific area of an image and transfer it to
consume less bandwidth and volume are recorded.
Installation of a camera instead of multiple cameras,
installation and maintenance costs greatly reduced. It can also transfer the
whole image instead of part of the occupies less bandwidth.
- IQ Camera:
Zexon ptz IP cameras can also provide more opportunities to
offer image. The intelligent design of this camera can be pressure on the
operators to greatly reduce data transfer and does important work to increase
the efficiency of video monitoring system.
Activating the motion detection feature, the camera can
detect and report any incidents to the scene as quickly. If a warning system
built into the camera speed camera alert function is impaired.
Another useful feature is the camera to detect movement.
This feature can be a virtual path of movement of all moving parts of the image
to be drawn in any event be easily traced.
Zexon dome IP camera functionality can be increased by
adding additional features.
