Building Management System

Building Management System (BMS) is a high technology system installed on buildings that controls and monitors the building’s mechanical and electrical equipment such as
air handling and cooling plant systems,
power systems,
fire systems, and
security systems.
Closed-circuit television (CCTV) is a popular form of surveillance that uses video cameras to transmit a signal to a specific destination on a limited set of monitors in a closed network. Banks, airports, industrial plants, military installations, and convenience stores commonly use CCTV, which can operate continuously or can be activated to monitor particular events. CCTV is a popular tool not only for security, but also for monitoring the operations of a business or organization.

When choosing CCTV for security or business needs, the key questions are what kind of camera to use, where to store the images and how to monitor and access them. A consultation with Symetrix can determine the answers to these questions, which depend on many factors including purpose, location and local conditions.
Access Control
Biometric Access Control
Energy Management System
Optergy is an advanced hardware and software platform that provides a virtual window into your building. It is a tool that provides real-time and on-line data and allows facility managers to easily track and control energy by answering the following questions:* Where is the energy being used?* When is it being used?* Why is it being used?* How much does it cost?* How do we measure it?The built-in web browser allows instant access without any limitations on simultaneous logins.
What is a Building Management System and how does it work?
The BMS is a “stand alone” computer system that can calculate the pre-set requirements of the building and control the connected plant to meet those needs.
Its inputs, such as temperature sensors and outputs, such as on/off signals are connected into outstations around the building.
Programmes within these outstations use this information to decide the necessary level of applied control.
The outstations are linked together and information can be passed from one to another.
In addition a modem is also connected to the system to allow remote access.
Components of BMS
Basic Functions

• Equipment scheduling (operating equipment as required)
• Optimum start / stop (running of HVAC equipment only during occupancy)
• Operator adjustment (accessing of set point to tune
the system)
• Monitoring (logging of temperature, trends, equipment start & run time, operator log on etc.)
• Alarm reporting (notify failed equipment, out of limit temperature / pressure)
• Provide status of specialised system like SCADA, lighting
• Control, load management, access control, etc
Benefits of BMS
Alarm System
Hybrid Digital or Full IP Security Cameras
Hybrid cameras are in essence, Analog Transmission cameras that record to digital video recorders (DVR), A great bang-for-buck solution while still offering high quality video recording.
IP Security cameras are full digital transmission and recording via IP cameras and record to network video recorders (NVR).

Fixed or Point Tilt and Zoom (PTZ) Security Cameras
Fixed cameras remain in one position. PTZ cameras can be moved left to right, up and down and zoomed in and out via a computer, DVR or PTZ joystick. These cameras often are used in casinos, shopping malls and other public places where it is imperative to access clear identification of moving people and objects.

Indoor or Outdoor Security Cameras
Outdoor cameras are built tough to withstand the elements, while indoor cameras can be more delicate.
Infared Security Cameras
Most cameras today are digital color with infrared LEDs, which films in color by day and in black and white IR by night. Infared cameras provide the best picture in low-light viewing situations.

Vandal Resistant Security Cameras
Depending on the location of the camera, it may be necessary to make it resistant to vandals with a tough exterior. Consider this option for cameras in a vulnerable location.

Day and Night Security Cameras (Low Light Cameras)
Infared cameras usually film in color during the day and then switch to black and white when it becomes dark. A photoelectric sensor detects the darkness and turns on the LEDs and flips the camera to black and white.
Security Cameras

Symetrix digital video recorders (DVR) are top of the line products to record and store the images and audio your camera captures. Our DVRs are feature-rich and make it easy to search footage, and maximize use of disk space.

DVRs are purpose built appliances and store what they record on a HDD (Hard Drive). Advantages of this architecture include quick and easy access to the video archive, and the ability to connect to the Internet for remote viewing from anywhere as well as iPad and iPhone support.
Digital Video Recorders (DVR)
Remote View CCTV Stations
Systems where many cameras are required can benefiet from having a remote view station to integrate up to 128 cameras on one view, and allow for easy retreival of footage from DVR's that are located in server rooms or remote sites. we provide customised remote view solutions to our customers to suit their needs.
Keypad access control is a simple, very low cost solution to allowing a small number of users access to a single, semi secure area.
Keypad access control systems are typically not as secure as a card/tag or biometric access control system as access pin codes can be shared, leaked, and published.
Because a PIN code is all that is required to gain access to the area, it is recommended that these systems are not used for areas requiring high security, or access by many people.
Keypad Access Control
Card and Tag Access Control
A cost effective and secure method of controlling access to one or more areas.
Each person is allocated a unique proximity tag or card, which identifies the person to the access control system.
When a proximity card or tag is swiped, the system will then attempt to identify the person, and ascertain if the have access privileges for the selected door, as well as if they are allowed to access the selected door according to the access schedule.
Finally, after these checks have been completed, the access control system will unlock, or open the door, allowing access to the secure area.
The attempted access will be logged, along with the person, date, time, and whether access was granted or revoked.
Generally there are two types of biometric access control systems available.
High security, integrated multi door biometric access control systems, requiring two or more verification points, with management software, scheduling, and anti pass-back measures are some of the most secure access control systems available today.
The second type of biometric access control systems are the stand alone, single door biometric devices prevalent at some electronic hobby stores. These systems can be less secure, and cost more to install than a typical card and tag system.
When it comes to biometric access control, it is recommended that unless you have the budget for a multiple verification point, high security system, a card / tag access control system is actually a more beneficial and cost effective security solution
Integrated Alarm and Access Control
Symetrix can provide a modular integrated hardware platform offering you an expandable, flexible and highly secure Access Control, Security/Intruder Detection and Automation package.
Using an Inner Range Concept 4000, or a GE Tecom Challenger security system, Symetrix can provide your business with a single point, highly configurable access control system, with alarm functionality.
Access to areas can be granted, or rejected based on the arming state for an area. Areas can be armed using both a 4 digit user code, or by double swiping a proximity card or tag.
Users can be granted door access to single doors, areas, or the entire system, as well as having the ability to arm and disarm selected areas.
An alarm can sound, back to base monitoring alerted, and selected users sent an SMS message when unauthorised access has been forced for a protected area, as well as view security log reports via the keypad, or a connected PC.
we can monitor your alarm for you even though most of our clients choose the text message alert system which we offer. If you opt for this service, your alarm system will be connected to a remote central monitoring station, which receives signals that report the conditions of the area being monitored.

Sensors are devices which detect movement and trigger an alarm, these sensors could be movement sensors, vibration sensors or heat sensors depending on how advanced our alarm technology is.

Your alarm panel is the brain of the whole security system. Panels (or controllers) take information from the sensors and process this into a code that alerts the monitoring station about what part of the monitored area is being intruded. There are many modules which connect into an alarm panel, as one of our experts which options are available for your install!
Alarm Panels

Customers who opt for alarm system monitoring can see their report online in real time by requesting a login and password to our customer portal. this is often very beneficial for business owners to check when their staff are arriving and leaving their premises, or to ensure their system is being armed properly.
Lighting Management System

Lighting control systems typically provide the ability to automatically adjust a lighting device's output based on:
Chronological time
Chronological time schedules incorporate specific times of the day, week, month, or year.
Astronomical time
Astronomical time schedules incorporate sunrise and sunset times, often used to switch outdoor lighting. Astronomical time scheduling requires that the location of the building be set. This is accomplished using the building's geographic location via either latitude and longitude or by picking the nearest city in a given database giving the approximate location and corresponding astronomical times.
Space occupancy is primarily determined with occupancy sensors.
Daylight availability
Electric lighting energy use can be adjusted by automatically dimming and/or switching electric lights in response to the level of available daylight. Reducing the amount of electric lighting used when daylight is available is known as daylight harvesting.
Alarm conditions
Alarm conditions typically include inputs from other building systems such as the fire alarm or HVAC system, which may trigger an emergency 'all lights on' command for example.
Program logic
Program logic can tie all of the above elements together using constructs such as if-then-else statements and logical operators.
Fire Alarm System
Intercom Systems
Audio intercom systems allow users to communicate with their voices from different rooms within a large structure, such as an apartment building or office complex. External audio intercom systems let residents or employees screen prospective visitors from the outside point of entry. Internal audio intercom systems permit communication between rooms at home, or enable public announcements and other quick conversations in the workplace.
Audio Intercom
Audio / Video (AV) Intercoms
Like audio intercom systems, video/audio intercoms may be installed outside or inside a home or place of business. In addition to clear sound, video/audio intercoms offer sharp images, made possible by an audio and video transmitter and receiver in a single cabinet. Unlike audio intercom systems, the advantage is that users can see potential visitors and other conversation partners, which creates more security and increased peace of mind.

Symetrix offers video/audio intercom systems with innovative features such as color imagery, video memory, and pan, tilt and zoom views.

Phone entry intercom systems connect directly to the resident phone lines in a building. Residents are called without making a call to the central office, which bypasses the expense of telephone charges. Phone entry intercom systems offer lower costs, convenience and privacy, as the dialed phone number remains unrevealed.
Phone Entry Intercoms

IP intercom systems distribute audio and video signals on a local area network in an apartment building or office. The intercom system acts like any other device on the local area network, which allows for flexibility. Multiple locations in different buildings can be connected for maximum reach.

IP Intercoms can integrate with VOIP systems, allowing advanced functionality such as IVR, digital PABX integration, extension trunking over the internet, and intercom call logging / reporting.
IP Intercoms

Symetrix Data and Security can provide your business with a 24 Hour, 7 Days a week intercom monitoring service.
