Uninterruptible Power Supply (UPS) for Surveillance Camera


Security cameras are at the heart of both individual and corporate security strategies today. Camera systems, which have a wide range of applications from homes to workplaces, factories to warehouses, sites to stores, are critical devices that must operate 24/7. One of the biggest risks in such systems is power outages. When the power goes out, cameras shutting down not only leads to loss of footage but also prevents the detection of risks such as theft, sabotage, and fire. Therefore, using a UPS for security cameras is not just an option but a mandatory security measure.
UPS systems kick in during power outages, ensuring that cameras, recording devices, modems, and network switches continue to operate. This means the security system never goes offline under any circumstances. Especially during outages at night or in critical areas, the uninterrupted operation provided by the UPS is crucial for maintaining security continuity.
Why is a UPS Necessary for Security Cameras?
Security cameras require uninterrupted power to function. All processes, such as image processing, recording transfer, data storage, and network communication, depend on electricity. Therefore, power outages can render camera systems completely inoperable.
- Video recording stops during a power outage.
- When the NVR or DVR shuts down and restarts, recording gaps occur.
- If the modem and switch shut down, the IP cameras lose their network connection.
- Alarm systems may be disabled.
- The risk of theft and assault increases during power outages.
It is known that in many cases, thieves try to take advantage of power outages. Using a UPS provides an additional layer of security to the system, ensuring that cameras continue to capture images under all conditions.
How does the UPS battery for security surveillance cameras work?
UPS provides regulated power to devices while connected to the mains and charges its batteries at the same time. When the power goes out, it switches to battery mode within milliseconds, preventing the devices from shutting down. This transition is so fast that the camera and recording device continue recording without any interruption.
UPS’s responsibilities:
- To cope with power outages
- Filter voltage fluctuations
- Provide protection against short circuits and overcurrent
- Safely power devices such as NVRs, DVRs, PoE switches, and modems
Therefore, UPS is not only a backup power device, but also a security component that protects the electrical infrastructure.
Hangi Cihazlar UPS’e Bağlanmalıdır?
The entire camera system does not have to be connected to the UPS, but critical components must be powered through the UPS.
Equipment that must be connected to the UPS:
- Security cameras (IP or analog)
- NVR / DVR recording device
- PoE Switch veya normal switch
- Modem or router
- Video monitoring screen if necessary
If any of these fail, system integrity is compromised. In particular, if the modem and recording device are not connected to a UPS, camera operation will be inadequate.
Which UPS Type is Suitable for Security Cameras?
Kamera sistemleri hassas elektronik devrelerden oluştuğu için en doğru UPS tipi **Online UPS** modelleridir. Online UPS, elektriği sürekli AC–DC–AC dönüşümü ile en temiz hâline getirir. Bu nedenle kamera kartları, NVR cihazları ve switch gibi hassas bileşenler en güvenli şekilde çalışır.
Line-interactive UPS models can be used for small systems, but Online UPS is definitely the better choice for workplaces, apartment buildings, factories, or multi-camera systems.
Ideal kVA Capacity for Security Cameras
Since camera systems do not consume very high wattage values, the appropriate UPS capacity is generally within the following ranges:
- 1 kVA Online UPS → 4–8 camera home, small store
- 2 kVA Online UPS → 8–16 camera workplace
- 3 kVA Online UPS → Systems with 16–32 cameras
In larger plazas, factories, or professional systems with dozens of cameras:
UPS models may be preferred.
When selecting a UPS, the total power consumption, number of cameras, and wattage of the recording device must be calculated.
UPS Supply for Security Cameras from RedSan Store
Online UPS models with appropriate power ratings for security cameras (1 kVA – 2 kVA – 3 kVA – 6 kVA – 10 kVA) are available at RedSan Store. You can make the right UPS selection with expert support to determine the most suitable capacity for your system and strengthen your security infrastructure against outages.
Additionally, you can get detailed information about UPS models according to your needs through RedSan Store and consult the expert team on how many kVA UPS you need to use technically.
Advantages of using UPS for security surveillance cameras
aUPS protects the security system not only during outages but also during daily grid problems. Therefore, using UPS directly contributes to both device health and overall security.
Main advantages:
- The system continues to operate during a power outage.
- No data loss occurs
- Camera lenses and sensors are protected
- NVR/DVR systems are not damaged
- Remote monitoring is not interrupted because the modem does not turn off.
- Camera recording continues during an attack or attempted theft
UPS is a serious security barrier, especially since power outages are used as a tool in most theft attempts that occur at night.
What to Consider When Choosing a UPS?
Not all UPS systems are suitable for every camera system. Even if camera systems consume low wattage, it is important to select the correct UPS model because they contain sensitive electronic circuits.
Important points to note:
- Being an online UPS
- Total power consumption of the devices to be used
- Expected downtime
- Battery quality and capacity
- Backup period
- PoE switch and recording device watt values
Selecting a device that meets these criteria both extends the device’s lifespan and ensures uninterrupted security.
