Power supplies can be imperceptible, being literally out of sight. However, they play a critical role in the effective functioning of the security system. Choosing the right power supply unit is necessary in order to ensure that the installed system will ensure the achievement of the desired result, and, ultimately, will guarantee high profitability.
A power supply is a vital element of any system, ensuring a long, trouble-free operation of the system, but this is not always taken into account. End users and integrators want to see a system that provides around-the-clock security, and at the same time they rely on a return on investment. High costs caused by product unreliability or system design flaws are the last thing integrators or end users would like to encounter. The variety of power supplies offered meets everyone's needs. Choosing the right option for your case, you guarantee a trouble-free operation of the system and a high level of reliability.
Difficulties: going beyond the permissible voltage.
The difficulties in choosing and installing power supplies for a variety of video surveillance systems or access control systems go beyond simply providing the right voltage. Factors such as cable size and length, and the condition of the power supply can lead to a voltage drop. The result of a voltage drop will be the unstable operation of the devices and a reduction in their useful life. It may turn out that the power supply will be perfect for your system, but the wiring is not. Therefore, the choice of all components should be approached systematically.
Different devices that make up one system are able to withstand different voltages, so installers must be sure that each device receives adequate voltage. Many online fixtures are available for calculating voltage drops based on variables such as current and cable length. Another important factor is the availability of backup batteries needed to maintain the system in the event of a power outage.
Network technologies.
The transition of the security industry to network systems using Internet protocols has led to a paradigm shift in the design and installation of power supplies. Today, many network system components operate at 15 watts of power, connecting a single cable to a network using PoE technology. Network switches can include integrated power supplies with PoE technology, and using a power injector will provide the necessary power. Some PoE switches may not support PoE + technology (IEEE802.3AT), designed for certain devices that require higher power.
Adapting to customer needs.
Professional integrators prefer to turn to the best manufacturers in the field, especially when they are faced with a task requiring special solutions.
Collaboration to meet changing nutritional requirements.
Power requirements are constantly changing. For greater efficiency, system integrators should work closely with other companies and manufacturers of security systems to ensure absolute system compatibility.
New technologies lead to new products and vice versa. In the case of nutritional solutions, it is critical for integrators and end users to constantly keep in mind the need to think about ensuring proper nutrition. Although power supplies are most often out of sight, they should in no case be ignored.
