Why You Need The Right Cctv Power Supplies
Reliable source of power –
Its an obvious point to make but CCTV cameras that dont have a reliable source of power arent much use. But how many people think about this when they install CCTV? The right CCTV power supplies are vital if you want a trouble-free system.
CCTV power supplies provide 12V and 24V output to CCTV cameras. You can also use them for other security equipment, if you wish. This can include monitors, entry phones and alarm systems.
The power supply model you choose depends on your CCTV system. Its important to contact a CCTV security firm for the right advice. In general, though, look for CCTV power supplies with:
low working temperatures
short circuit and overload protection
UL, TUV and CE approvals
universal AC input
a high efficiency rating
EMI filter built in
a 100% full load burn-in test
Surges and short circuits –
Lightning and faults in the grid can damage your electrical systems. CCTV power supplies protect your cameras from electricity surges and short circuits. The right power supply will keep your CCTV system intact. You can then foil any intruders who think they can benefit from a power failure.
Different systems –
A power supply unit also gives you flexibility. It lets you link the power for your cameras to a different electrical system to the one used by your premises. This can be very useful.
Many intruders will aim to cut your electricity before they break into your building. But if you use a different connection for your CCTV cameras, the intruder may overlook this. Despite any failure of the main electrical system for your premises, your cameras will still work.
Even distribution –
A good power supply system distributes electricity evenly. All your cameras remain working with the right amount of power. Uneven distribution can lead to failure of one or more cameras. This upsets your CCTV coverage.
Battery chargers –
If your main source of electricity fails, you may want battery-powered cameras to continue CCTV surveillance. But batteries run down. You need to keep your camera batteries at full strength with a charger so that your backup system is reliable.
To help you achieve this, some CCTV power su
pplies come with battery chargers. These keep your CCTV camera batteries topped-up. You can then have a more secure system.
