Top 8 BMS Companies in the 2018

Top 8 Global BMS Companies in the 2018

This is 2nd post in this blog regarding BMS - Building Management Systems. The rising need for integrating smart automation systems with the modern infrastructure is encouraging various building management system companies across the globe to offer superior and premium quality solutions for the evolving audiences. The objective of the Intelligent Buildings Management Systems (IBMS) is to centralize the monitoring, controlling operations with innovations, technological and skilful management of facilities within the building (From BMS Room). This system helps to achieve more efficient building operations at reduced energy and labor costs while providing a safe and quality working environment to the occupants. IBMS include wide range of variety of products, such as general light control, access control, security control, communication protocol, HVAC control, outdoor controls and others. Intelligent building is one of the emerging concepts in which modern infrastructure is being equipped with a variety of automated and manned control systems and monitoring devices.



Global Integrated Building Management Systems Market Analysis
Flexibility offered by various open integrated building management systems is one of the key factors fuelling the global IBMS industry to witness a CAGR of more than 12% by 2021. The ability of open systems to function as fully interoperable control systems and define protocols enabling the co-existence of multiple systems on the same platform make them the most viable choice for the modern companies willing to create automated or intelligent buildings. Furthermore, manufacturers are also leveraging these open systems as they allow the conversion of dissimilar products into seamlessly networked systems offering low cost and enhanced features often unavailable in proprietary systems.


Moreover, The Indian economy has shown steady growth in the last decade, despite the global economic meltdown.

Voltage & Amper Guide for your CCTV Camera

Voltage drop is a term that we hear about all the time in the surveillance industry. While many people talk about it and use the charts and calculators provided by different sources, I think a smaller amount of people fully understand the physics behind it. Today I want to give a quick review of the ideas behind voltage drop and then some practical tips for installing security cameras or any other equipment.
Equation
Here is the equation for Voltage Drop:
Voltage drop=( 2 * (length of run in ft.) * (resistance factor) *(current load in Amps))/1000

The length of the run is pretty simple; it is how long the cable is between the camera and the power supply.
The resistance factor is determined by the wire used and there is a chart in the NEC Chapter 9, Table 8 (rule of thumb, thinner wire will have higher resistance).
The current will be defined by the camera and will be found on the spec sheet.

Voltage Drop Example (300mA Security Camera)
Here is a quick example:  200 ft. run, 18 Gauge wire, 300mA camera
VD=2 *(200)*7.7 Ω *.3A/1000
VD=.924 V

Voltage Range
Cameras need a certain amount of voltage.  There is normally a range of ±10% of the rated voltage, so for this example we will say that a 12v camera can work in a range of 10.8v up to 13.2v (±10% of 12v is 1.2v). If a CCTV camera gets too much voltage, it will fry, and too little will not power it on.  So if the power supply is exactly 12V at the source, then it will drop .924V in 200ft and supply the camera with 11.076V, which is in the range of operation.

Voltage Drop
 One thing to remember is that the number for the voltage drop is not dependent on the supplied voltage.  So if a 12V camera loses 2 volts, it wouldn’t power on because that is a 17% loss, but if a 24V camera loses 2 volts, it will work because that is only an 8% loss.  So 24V cameras can run farther.
So the final test in for your setup is determining the Voltage percentage drop:
VD%=( VD/Source Voltage)*100

From our example above:
VD%=(.924/12)*100
VD%=7.7% (which is in the range)


If the proper power is not supplied to your CCTV equipment, it can cause it to lose signal or in some cases cause your camera(s) to fry!  Two essential things to consider include Voltage and Amperage.
Most of the below data concerning voltage and amperage can be considered for 99% of systems.  Cameras will usually use either a 24VAC or 12VDC current.


Basic voltage & amperage reference guide for proper power supply to your CCTV equipment.


Wiring Tips
All of this stuff is neat and I hope that is explains the science behind it all little more. Just remember:
Longer Run = more Voltage Drop
Thinner wire (higher gauge) = more Voltage Drop
Larger Amps (more powerful camera) = more Voltage Drop
Higher source voltage = Less Voltage Percentage Drop

For Installers
Final point, there are times in which installers have called in because a camera is not working and they claim that the wire is supplying enough volts. The problem with that is that they unplug the camera and connect a Voltmeter to the two wires. The Voltmeter has a very low amp draw, and will show less voltage drop because of that. Once the camera is reintroduced in the circuit, the voltage drop will change, making the measurement ineffective. So we need to run the numbers on paper to determine the drop.

Quick instructions on selecting a power supply:-

The only information you need to have in order to find the correct power supply for your device is the Voltage / Volts (V) and Amperage / Amps (A).

Voltage has to be an exact match. A 12V DC device needs a 12V DC adapter (10% toll).

Amperage is the amount of power your device uses. The adapter you order has to be able to supply AT LEAST the amount of Amps your device draws. If your device states it is 12V 3A, a 3A adapter can handle that load, but so can a 4A and 5A. The higher amperage (amp) power supply will not have to work as hard to handle a smaller load, and will run cooler and more stable. 

If the Amperage of your device is uneven, such as 3.13A or 4.16A, always round up. 3.13A rounds up to a 3.5A adapter, a 4.16A device will round up to a 4.5A or a 5A. 

If you match these two specification (V and A), the power supply will work for your device. 

Detailed Instructions:

In order to find the correct power supply for your device, you will need two pieces of information. These are Voltage (measured in Volts or V) and Amperage (measured in Amps or A). You can find this information off the back of the old power supply, or off the back of the device itself. If you do not find it on the device, you can check the manufacturer's website, or in the device's manual under "specifications".

Voltage:
All of the power supplies we sell are 12V DC. They take any input from 100V up to 220V AC, which is what comes out of your wall socket, and output 12V DC. This is what most digital devices such as LCD screens, DVD players, Hard Drives, Audio Gear, and most other digital devices use. We only carry 12V DC power supplies, so if your unit is not 12 Volt, you will not find the correct adapter here.

Amperage:
Once you have confirmed that you need a 12 Volt power supply, you will need to find out how much power your device draws. This is called amperage. Next to the 12V in the specifications there will be another number followed by a capital "A" for Amps. You will need a power supply that can supply enough power for your device. If your device says it draws 3 Amp (3A), you need to use a power supply that can put out at least that many Amps. If your device states it needs 3A, then you can use a 3A, or 4A, or 5A unit. All will work. 

If the Amperage of your device is uneven, such as 3.13A or 4.16A, always round up. 3.13A rounds up to a 3.5A adapter, a 4.16A device will round up to a 4.5A or a 5A. 

Connector:
All our power supplies have a connector that is standard for a 12V DC device. Most 12V DC devices use the standard tip. This tip is 5.5mm (outer barrel) by 2.5mm (inner barrel) and is center positive. It is a simple round barrel connector. To repeat, if you match the voltage and amperage, then you should not have to worry about the connector type accept in the rare occasion when your device has an unusual connector such as a double barrel, or a 4-pin, but these are easy to spot as the jack where the adapter plugs in will not be a simple circular barrel with a pin inside.
