Digital high-definition hotel monitoring system is mainly to promote the hotel order, to protect the security of the hotel, and improve management with tools, so generally surrounding walls, entrances and exits, administrative office area in the hotel, front desk, restaurants, warehouses, engry room and other key parts installed digital high-definition cameras.Video image in real-time monitoring system, monitoring and storage, can greatly improve the working efficiency of the security personnel and timely processing industry, can effectively protect the safety of hotel property and staff, at the same time, digital high-definition monitor system can also help hotel, effective management of each department as the basis of reward and punishment, improve the staff's working efficiency.　　　

　　　In today's modern enterprise, hotel use digital high-definition video monitoring system, strengthen the employee attendance management, improve work efficiency, leadership on a business trip in other cities using PC or mobile terminals, such as tablets or mobile phones for remote monitoring, checking the real-time status of the hotel at any time.

Hotel digital high-definition security system

According to the different demand，there are three kinds of different mode of 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.

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.

3, Remote monitoring, remote monitoring is through the Internet to transmit video signal and switches are connected to the routing of the access network, remote access, through the NVR client can also use the server forwarding by P2P software remote client to access, also supports mobile terminals such as mobile phone monitoring.

Hotel digital high-definition security system and other system are also consists of three parts:
1.Front-end video acquisition
2. Signal transmission partsPart
3. Sorage and display

Front-end video acquisition usually have
1.The standard digital high-definition color video camera
Usually divided into 1 million / 1.3 million / 1 million pixels (not including lens, lens can choose according to need to monitor the point of view)

2.Digital high-definition dome camera
Usually divided into 1 million / 1.3 million / 1 million pixels (lens can choose according to need to monitor the point of view)

3 high-definition ir waterproof MP bullet camera
Usually divided into 1 million / 1.3 million / 2 million pixels.(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.Digital high-definition camera, infrared dome camera
Usually divided into 1 million / 1.3 million / 2 million pixels.(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.)

5 High-definition dome camera
Smart spherical cameras is divided into: high-speed ball, medium-speed dome camera, constant speed dome camera.

6,.Digital high-definition infrared IR dome cameras
Infrared smart spherical cameras into long-distance outdoor type, mini dome camera, outdoor and indoor mini dome camera, also can be divided into: high-speed camera, medium-speed camera, constant speed camera.

Second, the signal transmission parts

1.Transmission within 100 meters, digital high-definition cameras use network transmission, video camera interface is also a network interface, camera correlates side can use Internet direct transmission.

2.If more than 100 meters, the switch can be used for secondary exchange, exchange advice the number of not more than 3 times, because the data exchange takes time, so the more exchange can cause the longer video delay.

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

Third, 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 hotel digital high-definition security system:

First, the system choiceHotel digital high-definition monitor system mainly monitor the surrounding walls, hall, public areas, restaurants, warehouses, entrance, the front desk, elevators, administrative areas, such as occasion, stable performance, simple and easy solution is to control the cost of the core logic.In satisfying the function, quality, performance, price and service level, such as the pursuit of the most simple and easy equipment configuration, the optimization of system is the most reasonable method of reduce the cost of the system.And considering the hotel digital high-definition security 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 security system 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.

Second, the product selection

　　　　When choosing the front-end products mainly to meet the needs of monitoring situation, monitoring of the hotel 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, the extent of photographic camera, the scene reflected infrared condition to decide, each other 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.
     
Effect is satisfied, so in order to make the night night 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, the same is true for a flashlight if will be the light in front of the embryo to remove the estimated according to less than 10 meters.And the more is the digital high-definition infrared camera not see infrared lamp will shine more, because of the different light emitting chip electro-optic conversion efficiency, it is like a normal 100 - watt bulbs have not 30 watts of energy-saving lamps light emitting a strong point.

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, due to the 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 appear 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 see if factory take the corresponding measures on the infrared lamp heat dissipation.

Hotel there are many broad places such as, warehouse, parking lot, hall choose millions of high-definition infrared smart ball is relatively appropriate, if it is small or the location of the installation under the condition of low selection MINI digital high-definition infrared dome camera that will look more beautiful indoor small area such as rest areas, restaurants, channel intersection, the choice of the digital hd MINI indoor infrared dome camera.Because, after all, the intelligent ball can monitor Angle can be achieved without blind area monitoring, if there is a more important area of the environment can be set to guard this area a (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 dome camera, can choose to use a small pan 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 pan need external decoder, and the need to connect 485 decoder and digital high-definition cameras, because too complicated so easily cause malfunction.Therefore RongTian regard for similar occasion designed a rotating bracket, millions of high-definition cameras special rotating bracket, also called intelligent support high-definition cameras.This is Ratingsecu as a patent product, the appearance of the rotating 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 unified coding with and back-end communication to achieve various actions.

The hotel has parking lot entrances are often 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 the license plate special digital high-definition cameras and Angle to the scene to do test after will produce different effects (different angles) and installation.

In the corridor or elevator choose digital high-definition infrared dome camera, directly installed on the ceiling generally choose white will be more beautiful, better digital high-definition dome cameras installed.But choose digital high-definition dome camera also need to choose the cooling assured products.Because many manufacturer of digital high-definition infrared camera hemisphere is plastic material, and not in the infrared lamp calorific do heat treatment.

Third, according to the loading mode selection

　　Installed in indoor digital high-definition cameras to avoid light, should be installed along the light.Due to too long in some areas such as corridor to need two sets of digital high-definition cameras to monitor to the ideal, do not install the two opposite infrared digital high-definition cameras, infrared digital high-definition cameras because at night across the lamp is opened to let the camera to produce reflective phenomenon to see images effectively, this kind of situation as we like driving at night when the current face the oncoming car lights as we cannot see the road.So choose to install outdoors position also don't things as north and south, because thing front will make camera effect by direct sunlight.

　　Outdoor installing digital high-definition infrared dome 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.

When the power is concentrated to 220 v to make a first voltage stabilizing treatment, if you can use UPS (uninterruptible power supply) is more appropriate.Note as much as possible on the power supply position near digital high-definition 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 digital Gao Qingqiu machine or high-definition cameras, please must be in the top of the vertical rod vertical root lightning rod, and well grounded.This can effectively avoid lightning equipment.

Four, store and display options

　　The hotel monitoring according to the size of the project range from four images to hundreds of images.The following is the easiest solution to 64 4 picture a.
Four points by 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

　　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.

If nine points above 16 points is used within a 16-way NVR as storage and decoding, according to one: use a 42 inch hd display images will be divided into 16, according to two: using 4 sets 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.

　　If it is 16 points above 32 points is used within a 32 channel NVR as storage and decoding, according to one: use a 42 inch hd display images will be divided into 32, according to two: 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.

  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 x4 = 64 if you want to use the mouse to double-click the monitor which picture is become in relative display shows the single picture.

　　Above is the most simple backend systems, of course, whether a few road at the time of configuration NVR must reserve late extension necessary interfaces.
