Is there any Need for UPS for CCTV? 


CCTV known as Closed Circuit Television plays a key role in safety, either in the home or in the office. It protects the assets especially the capital, bonds, etc. from the thieves. Uninterrupted CCTV power supply (เครื่องสำรองไฟ กล้องวงจรปิด, which is the term in Thai) may risk to your life as unforeseen circumstances can happen anytime such as robbery in the home or the office, so having proper power supply on CCTV will help you to handle such situations. 

Why UPS for CCTV Cameras?

  • To function effectively, CCTV needs an uninterrupted power supply (UPS). The UPS system enables the CCTV to works efficiently even without the power supply.
  • It blocks the surges and keeps the CCTV stable when there is a fluctuation of electricity in the main supply.
  • UPS protects the Closed Circuit Television equipment from lightning.
  • The smooth functioning of CCTV cameras 

How UPS works in CCTV systems?

One end of the UPS is connected to the mains supply and another end to the DVR (where the recorded videos are saved). In the normal condition, the main supply provides electricity to the DVR, CCTV Cameras and UPS. After getting the electricity, the CCTV will work and will capture the video and the same will be stored in the DVR and case of UPS, the charge will be stored through the flow of electricity. On the off chance, if there is a power cut, then charged UPS will provide the power supply to the DVR and Closed Circuit Television (CCTV) and they will work efficiently. 

The UPS contains a Battery, Surge Protected Outlets, LCD panel, and much more. These entire elements work together to run the UPS. So, the varieties of UPS can be determined by changing the specification of the equipment. Generally, the UPS of 1500VA offers 20-25 minute power backup for 4 camera systems and if the CCTV system has 8 cameras, then the backup time will be around 15 minutes. Many agencies sell uninterrupted power supplies (ขายเครื่องสำรองไฟฟ้า, term in Thai) for such device and you can choose the UPS as per your requirement. 

Consumption of Power

As stated earlier, UPS consumes less power and it saves around 75% of electricity. The determining factors for power consumption are Volt and the Current.  

Overall, it can found out that UPS is quite essential for CCTV as it protects you and your property. So, stay safe using UPS for your home and office place.
