Central Control Room Surveillance
With regard to the distribution of CCTV cameras in malls and crowded as subways, streets, shopping malls, offices and large organizations and hospitals and ...nd the continuing need for images and camera control, camera surveillance room called the central control room or control room be provided for this purpose.CCTV monitoring room is a room where images of all CCTV cameras in this room that we can control and direct the camera controls such as zoom, rotate, etc. to make.In general, this room contains several large and small monitors, equipped with uninterruptible power systems, air conditioning and more.Given that the operator must spend long hours in this room,Therefore, monitoring should be in terms of welfare and comfort rooms in a way that will not diminish the quality of his work.Comfortable, well ventilated room temperature and room to sleep and rest and ... should be considered preliminary design.
Monitoring Room Facilities:
1. Collect pictures from different locations in one place
2. Control a multi-point camera
3. Determine the availability of each of the images
4. Monitoring images of all cameras
5. Access to recorded images, camera control, configuration and ...
With room monitoring and integrated CCTV systems that are Draray well designed, can be more secure with less, achieve high efficiency of operators and increase accountability.
Ergonomic design
Operational control room as the heart of any organization or organizations whose main role is to increase the working efficiency of employees plays.Since the control room operators work with CCTV systems or computer servers, must be properly designed in terms of ergonomics as well.Because the operator can spend a lot of time in the control room and therefore they should be considered easily,The design better and more accurate monitoring is essential Room.Control room design and layout displays on operator performance in achieving timely manner and without error will affect fail to notice.If the room environment and equipment used Kntrl, not Vzayf, ergonomic design the operator can create a sense of anger, depression and fatigue are The failure and Anxiety.The physiological effects detrimental to health and may also gastric problems - intestinal and cardiovascular cause.On the other hand, job stress can cause loss of motivation and conflict between colleagues and Thd, be compromising performance.
The definition of ergonomics:
Ergonomic goals include improving human performance, health, safety and comfort in their individual workplace design and equipment, methods of work and is on duty.The usefulness of video surveillance systems in a security system and confidential information that is achieved is dependent on the quality.Control room operators to achieve design performance failed to timely information and without error CCTV systems will have an impact.
Operators will be very effective duty if:
Easily have been sitting on chairs that are ergonomically designed.
In good condition and monitors the correct (in terms of ergonomic) installed.
Your camera is suitable for monitor brightness.
The following is an ideal control room involved:
Monitoring the size and shape of the room
Control room should be large enough so that it can be toys, equipment placed on itAnd there is enough space for working people.If the control room is too small or have the appearance of uneven or sloping roof with columns and is,It was Face design constraints. The defacement of the room can affect the way that it monitors being in addition to being able to scan multiple images the camera operator limits,He puts at risk the safety risks and damage to health.
It should also be enough space for maintenance of the equipment in emergency situations without interrupting the natural process control room, used, exist.If CCTV is likely to expand in the future Dvrbyhay system should have enough space for additional work stations and ergonomic equipment conditions exist.
The minimum size appropriate for the control room visible in the figure below

Figure 5. The minimum size of the room for a) wall) fitted with racks
Positions doors:
Entry and exit points should be designed so that wheelchair traffic and the large pieces of furniture in the room is easy to control.Are also suitable for convenient traffic should be considered.Standards and measuring the distance from the wheelchair in the figure below (in inches) is visible.
Figure 6. Select the appropriate size of the order.
Figure 7. Select the appropriate size for the wheelchair.
Toilets:
Toilets and free sites (yard) to close the control room, so that once a person is the operator on dutyIf you use this facility by him, the control room unattended and vacant
Windows:
The windows of the control room should be in every place there that take advantage of natural light, are provided. Natural light to artificial light is preferable for most people,Because it shows a view of the outside world. Must be implemented to control the amount of incoming light curtains and windows to monitor the location and line of sight of the operator is in the best condition.Vision standard pages 500-800 lux horizontal and vertical pages is 200 lux.
Lighting:
The control room lighting must be adequate for all tasks in the room. Lighting point Lighting broadcast more than is recommended. If the light intensity decreases,Can create problems in the screen image, as well as possible at the same time to do other things like read your writing tables and there is insufficient light,The result can be the wrong reading, writing, incomplete or illegible or inaudible reports and fatigue.Reflection in the monitor, lighting due to poor management could obscure the camera's image data, preventing operator attention to detail or the loss of an event monitor.
An example of the standard of lighting in the form below.
Figure 8. The standard lighting.
Temperature and ventilation:
Control Room temperature should be adjustable. This is especially important when the central control room at times when the building heating system is turned off,Is working. Thyzat of heat, and this must be considered in the design. The control room should be ventilated with fresh air,For air and old left can harm the health of operators and create ill will. Doors are closed when the air conditioning system does not work should not prevent the thorny operator.
Designed for workstation:
Due to the design of work stations on Performance, following factors affect the health and safety of the operator must comply with them. Height workstation components and equipment arrangement should be That for all operators to provide enough scope and space for knees and lower legs hip Ha, exist To all operators of any size and dimensions are not allowed to change your posture when you are sitting there on the chair.Sitting for long periods and can be repeated and constant state of fatigue is limited The Performance, effective individual health and safety and convenience.Workstation must have sufficient depth to accommodate all equipment and documentation When viewing images have monitors Otherwise write or phone operator can easily access and control panels.Also, if the operator fails to hands and arms resting on a workstation that will lead to fatigue, he was
.An example of the correct dimensions workstation is visible in the figure below.

Figure 10. a comfortable viewing angle.
Suitable seat
Incorrect sitting in a chair with ergonomic design of the job that can lead to musculoskeletal injuries will be reduced.The following tips are designed to chair based on information provided by the Executive Board on the safety and health with the heading "Regulations for display equipment" and operators should be trained in the proper use of these types of seats.Given that the operator may sit for a relatively long time constant and severe, chair should be comfortable Because it can lead to problems for Grdn, inappropriate sit back and be the head.To remedy the situation Apratvr, correct seat height should be adjustable to sit a person can put his feet on the ground to comfort mode.If an operator fails to do so must use the footrest. Adjustable abutment: Abutment must be adjustable in both height and slope Upper and lower back seat because it is important to be able to support the natural curvature of the spine can not keep up operator
Chair:An operator if your upper body using the armrests support herself, to recognize can sit in a more comfortable position. As it can be useful when getting up from a chair used
Ideally sit on a chair in the figure below is visible.
Figure 11. Standard Mode sit on the chair.
Monitors:
Calculating the size of the monitor to frame up crucial job details displayed visual (seeing) and the distance operators it is appropriate.If the operator is sitting far away to be able to analyze the details of the playback image of a small monitor This may affect the ability of the operator to assess the effectiveness of the image or picture settings without error had a reverberating effect And Irritation, eyestrain and headaches result. Each of these factors can also contribute to lower quality image recording.
The monitor should be placed in a position that when the operator scout accept them (get used to) sit situation more than a few minutes at a time to prevent incorrect.If the monitor is placed too much in height or width operator will be forced to see it, his neck raisedWhich leads to muscle fatigue and discomfort due to the unwillingness of operators will be monitored to see.
Surveillance cameras to monitor closely monitors the images are used to monitor Usually, called the incident or the point And allow image information without error and at the moment they scout.
Monitor directly in front of the operator and the accident should be approximately 0/5 to 1/5 meters and a diameter of 9-16 inches (22-40 cm) to be installed from him.Alternatively, the operator can easily look at the Sitting, to each of them.It is better to have two or three monitors to be deployed desk incident, the operator can see the pictures displayed on the central monitor And adjacent monitors for other use images that have a high priority. Monitor also can be set farther away from the workstation (rows and columns) or rows to be placed That it would be useful for providing a greater number photo.
Monitors set to be installed at a greater distance from the operator and have a larger size eg between 17-28 inches (42-70 cm). It has been proved The images shown on monitors set to gain more Kly, view of partial withdrawals are useful.Where large images on the type of tasks that must be scanned regularly Is needed to cover general understanding of the range of views which camera to look after the rapid diagnosis and more accurately be got,The use of monitors might, features two sets of interchangeable parts or images (switch) may be appropriate.. The structure of screen information to the operator to analyze and evaluate images will help more effective.
Images by position and location of monitors should be classified or after the election. Because they show images of specific hazardous area.This operator View Sort Results And regular monitoring more pictures of Tsadfy, that way without motivation and mobility, is less effective than the use of CCTV cameras will help.
With the help of technology several separate images on one screen or scan multiple images by multiple topologies camera, much different picture will be presented on one screen.
Multiple images, reducing image detail to be operator This visual tasks such as control operators who focus on the screen without any errors or reading takes it harder.As far as the risk of error increases. If you need detailed operator herself, to recognize the image picked up to 4 photos on each monitor is recommended.Automatic switching Photos provided an alternative approach for the discovery of images on surveillance cameras, but the leads about any change in the details of the images necessary for operators This is because this method may cause confusion or inconvenience and also not seen the changes and details should prevent it .One of the issues is considerable and important number of camera shots An operator of CCTV cameras alone and effectively at any moment be able to scout them.Although research in this area has to offer conclusive evidence, but the operators believe The maximum number of symbols cameras that they are able to monitor them effectively,16 Front or less, and just over half said the most out of their operators between 1 and 4 facing the camera. Experience has shown If you increase the number of monitors Yabd, observers efficiency in finding targets in the center of the image begins to degrade.
Also monitors in the control room can be grouped in different ways that these groupings can be seen in the figure below.
Figure 12. Grouping Monitor.
Fit and trained operators:
Many tasks require branches of sight and seeing the CCTV operators are Therefore, it is important to improve the efficiency of control room visual design ensure.Factors affecting the efficiency and visual comfort include: lighting (artificial and natural), the quality and placement of displays and control properties of surfaces in the room.eye tired or sore red eyes and headaches can be the result of exposure to light during the work shift was weak.
Learning to work properly:
Operators also need to be taught the correct way. Improper posture and mobility can lead to musculoskeletal disorders is inadequate.If the operator station design Kary, because of weakness in equipment or Sndly, an incorrect posture or body rotation during work have to constantly And it leads to a range of physiological problems keep mixing them with upper trunk injuries (Sr, Grdn, arms and wrists Dstha,) is.In short, it may be Mvqt, operator fatigue, pain or discomfort in the lower limbs and tingling in the fingers experience.And in extreme cases can lead to more serious disabilities such obvious injuries of the upper limb (WRULDs) is Ensure that the control room design has been done by people trained and skilled as well as training courses on the subject of health and safety for the operator can be enough To prevent such risks that have an adverse effect on health and Safety, help efficiency and comfort
Watch the right time:
Although the investigation was conclusive proof that the length of time that an operator can not provide effectively monitor Watch CCTV operators downtown but believe that most of the time, between 30 minutes and 2 hours Laws, health and safety (HSE) has expressed using the screen instructions. Although the main use of display rules as watching TV and movies is excluded However, HSE advice to all visual needs, in which the screen is used for. These laws are used to prevent fatigue from these devices:Short breaks and periods of rest might, more satisfactory long-term, but what (if the opportunity) is.For example, 5-10 minute break after 60-50 minutes continuous monitoring, or (with) rest accurate with better keyboard than 15 per 2 hours.Operators working days must be planned and organized to enable operators are forced away from the screen at regular intervals to rest.But this time, the rest must be programmed in a way that is consistent with the incidents of their times less.Operators need for education to reduce health and safety risks are described that provide both visual work. Operators should be discouraged from watching television during the hours of rest.
