In today's modern logistics park management, the use of digital high-definition video monitoring system, improve the work efficiency, to public places for video surveillance, security and management of real-time control of the whole logistics park.
  
Logistics park digital high-definition monitor system


According to the demand of the different ways there are two different transmission

1, A local short distance monitoring is the simplest way of monitoring, as long as each camera through the cable connected to the switch, will NVR is also connected to the switch and then according to the pictures' way and need to watch the picture size to choose the size of the hd display, the diagram below:

2, long-distance transmission, on the front end cameras and monitoring room is more than 100 meters can do secondary exchange through the switches, but suggest not more than three switch because digital switching takes time, if the number of exchange too much can lead to a significant delay. So more long-distance transmission using optical transceiver to transmit signals into light through the optical fiber, the diagram below:

Logistics park digital high-definition monitor and other occasions monitoring system are also consists of three parts:


1, front-end video acquisition

2, signal transmission parts

3, storage and display

Usually have the front-end video capture

1, the standard megapixel hd ip ir color camera
Usually divided into 1 megapixel / 1.3 megapixel/ 2.4 megapixel (not including lens, lens can choose according to need to monitor the point of view)

2, megapixel hd ip ir dome cameras
Usually divided into 1 megapixel / 1.3 megapixel / 2.4 megapixel (lens can choose according to need to monitor the point of view)


waterproof megapixel hd ip ir camera
Usually divided into 1 megapixel / 1.3 megapixel/ 2.4 megapixel (lens can choose according to need to monitor the point of view, also can choose according to the distance monitor camera corresponding intensity of infrared lamp.)

4、megapixel hd ip ir dome camera
Usually divided into 1 megapixel / 1.3 megapixel/ 2.4 megapixel (lens can choose according to need to monitor the point of view, also can choose according to the distance monitor camera corresponding intensity of infrared lamp.)

megapixel hd ip ir speed dome camera
Usually divided into high speed dome camera ,middle speed dome camera ,


6、megapixel hd ip ir speed dome ptz camera
megapixel hd ip ir speed dome ptz camera into long-distance outdoor type, mini type outdoor. And indoor mini type. Also can be divided into: high-speed speed dome camera , medium-speed speed dome camera.
Part Second, the signal transmission parts

1, 100 meters of transmission, digital high-definition cameras use network transmission, video camera interface and network interface camera usually end you just need to use MB network cable, if the distance in 100 meters of transmission range is used directly connected.

2, if more than 100 meters can use switches for the second exchange, but don't suggest the exchange of more than 3 times, as the data exchange takes time so if exchange will cause the more video delay too long.

3, long-distance transmission, the ideal is to use optical fiber transmission, the cable with optical fiber transceiver into a fiber optic cable transmission.

4, in some occasions such as indoor already decorate good cannot wiring can use wireless WIFI transmission.

Part three, storage and display

1, it is recommended to use professional embedded NVR (digital hard disk video recorder)

2, also can choose digital NVR (server) in the remote monitoring for remote forward.

3, the display can choose according to the demand of the frame size to hd display, if you need big picture feature can choose joining together to solve the display screen.


How to choose the logistics park digital high-definition monitor system;


Part One, the system choice

Logistics park digital high-definition monitor system mainly is to monitor various vehicles, parking entrance plaza, public areas, such as, stable performance, simple and easy solution is the core of cost control logic, to meet the function, quality, performance, price and service level, such as the pursuit of the most simple device configuration, the optimization of system is the most reasonable way to reduce the cost of system. Comprehensive consideration of logistics park and digital high-definition monitor system construction difficulty, maintenance personnel and operating factors of the future system expansion, system reserved interface.

As far as possible simple overall system design is the guarantee of system reliability, it is recommended to use embedded NVR (digital hard disk video recorder) is shown as a system of video storage and processing equipment, because the NVR is chip level relative PC hardware decode need CPU resources for easier to guarantee the stability of long work hours, available for remote monitoring of NVR can also achieve remote platform. Can also configure a server to forward. Make sure need to monitor the route at the same time, due to the remote monitoring of ways on how to directly determine forwarding servers work pressure. So, according to the needs of remote monitoring at the same time 'way to select the server configuration can ensure that economy and rationality.


Digital high-definition monitor construction are smaller than in the past simulation monitoring construction, because it is a logical connection so as far as possible to nearby group point to point transmission, is near the few points have been a switch in then uniform transmission, if the distance is far away from the monitoring using optical cable transmission is the most economical way. Because digital high-definition cameras 720 p code flow is 3 m, 1080 p at about 6 m, so the transmission at the same time more than 15 points need to switch to gigabit Ethernet cable, but at the same time suggest transport more than 10 points with gigabit Ethernet cable.

Part Two, the product selection

When choosing the front-end products mainly to meet the needs of monitoring situation, monitoring of logistics park are generally based on the basic concept of security and management, safety is more important than during the day night, the utilization rate of natural monitoring at night than during the day more ordinary therefore recommend the use of infrared devices, below is how to choose the digital high-definition infrared camera to make a simple introduction.


Pay attention to a lot of digital high-definition infrared camera manufacturer mark refers to the distance of the infrared light and night vision distance from several meters to hundreds of meters, and the visual range at night is can see clearly from the monitor effective maximum distance, is by the infrared lamp luminous distance, degree of photographic camera, the scene reflected infrared situation to decide. Between them as the result of the computer's CPU, memory, video card, the matching of chipset, any link efficiency reduction will reduce the efficiency of the whole system, so in order to make the night night effect is satisfied, in addition to choose relatively regular factory equipment to choose the visual Angle, digital high-definition cameras visual Angle, the smaller the configuration of the smaller Angle of infrared lamp, under the same light source is emitting Angle directly affects the size of the light in the distance. This and flashlight is the same as if the light in front of the embryo to remove as estimated according to less than 10 meters. And the digital high definition

Important note:
Choose the digital high-definition infrared camera
Not only look at its effect, because the red digital high-definition cameras when opening the lamp in the night outside the law of conservation of energy, such as the use of electro-optical conversion efficiency is 10% of the infrared lamp, if 2 watts of electrical power consumption in addition to produce 0.2 watt light must also produce 1.8 watts of heat, because heat is produced in the small area of the wick so will lead to a small area of the temperature of the heat accumulation is very high, more than the wick working environment temperature will be more and more luminous efficiency is low, and rapidly accelerate the aging of luminous body make service life shortens greatly, so must pay attention to when choosing digital high-definition infrared camera to understand whether manufacturers on the infrared lamp heat dissipation taking corresponding measures.

Logistics park there are many broad places such as park plaza, public areas, select millions of high-definition infrared smart ball is relatively appropriate, if there is a more important area of the environment in this area can be set to the guards who (after free time stay fixed position can be set), to avoid the ball machine due to monitor the other area when stay in other places while ignoring the important occasions of the video. In the important gateway must use fixed focus of digital high-definition cameras, when selecting a fixed digital high-definition cameras pay attention to the choice of viewing angles, as far as possible don't choose too big Angle, because the Angle is too large display of objects too small lead to see not clear.


On-site monitoring Angle must be bigger but due to the Angle will affect the effect of infrared light, and the picture is too small not easy to get effective images and res infrared smart ball, can choose to use a small ptz to solve, is to choose small Angle digital high-definition cameras and then mounted on a small stage with the rotation of the small Angle to expanding the scope of the monitor, but usually small ptz need external decoder, and the need to connect 485 decoder and digital high-definition cameras, because too complicated so easily cause malfunction. Therefore RATINGSECU regard for similar occasion designed a rotating bracket, millions of high-definition cameras special rotary bracket, also called intelligent support high-definition cameras. This is RATINGSECU as a patent product, the appearance of the rotary bracket is a very beautiful bracket of digital high-definition cameras, but in the stepping motor was designed on horizontal piece and decoding board will be 485 signal by digital high-definition cameras coding plate and unified.

Logistics park car is usually need to see the license plate, digital high-definition cameras generally can meet the needs of see the license plate in the daytime, but at night because the vehicles driving lights, which seriously affected the image imaging infrared camera because if you use the standard digital infrared light onto the plate forming strong reflective characteristics (due to plate the surface of the reflective paint) while also lead to a piece of white can't see the above figures, so be sure to choose special digital high-definition cameras, license plate and Angle to the scene to do test after will produce different effects (different angles) and installation.

Part Three, according to the loading mode selection

Installing the outdoor megapixel hd ir speed dome ptz camera, choose as far as possible to avoid next to an object, due to open the lamp will illuminate at night to object reflective will affect the picture shows.

Centralized power supply will be 220 v first do a voltage stabilizing treatment, if you can use UPS (uninterruptible power supply) is more appropriate, pay attention to the power supply as much as possible in the position of the near digital hd ir ptz cameras because of the 12 v voltage in the wire transmission pressure drop will be very big.

If a small area or a building there are a few points are near the nearest switches or transmission equipment is far, the choice of a switch is put in this area, all concentrated point after transmission can save quantities.

If the stud to install outdoors megapixel hd speed dome camera or megapixel hd ip ir camera , please must be in the top of the vertical rod vertical root lightning rod, and well grounded. This can effectively avoid lightning equipment.

Part Four, store and display options
Logistics park monitoring according to the size of the project range from four images to hundreds of images. The following is the easiest solution about the 4 picture and 64 picture.

1. Four points using a four-way NVR as storage and decoding display, and then use a 22 inch high-definition images will be divided into four display, if you want to use the mouse to double-click the monitor which picture shows that into a single picture.

2. If it is more than four points within nine points can use a 9 NVR as storage and decoding display, and then use a 42 inch high-definition images will be divided into nine display, if you want to use the mouse to double-click the monitor which picture shows that into a single picture.

3. If it is more than nine points is used within 16 points a 16-way NVR as the storage and decoding display:
use a 42 inch hd display images will be divided into 16,
using four 42 inch high-definition monitor stitching, according to the set of images will be divided into 16 to display on the image to select the size and cost requirements.

4. If it is 16 points above 32 points is used within a 32 channel NVR as the storage and decoding display:
use a 42 inch hd display images will be divided into 32,
(2)using 4 sets 42 inch high-definition monitor stitching, according to the set of images will be divided into 32 to display on the image to select the size and cost requirements.

5. If it is 32 points above 64 points within the use of four 16-way NVR as storage and decoding display, using four 42 inch or larger high-definition monitor each will monitor screen divided into 16, according to 16 x 4 = 64 if you want to use the mouse to double-click the monitor which picture is become in relative display shows the single picture.

The above is the most simple backend systems. , of course, whether a few road must be reserved when configuration NVR late extension necessary interfaces.
