Can CCTV Camera Work Without Electricity? – Everything You Need to Know

CCTV cameras have become a part of everyday security — in homes, offices, shops, and even at temporary event sites. But there’s one question that comes up often:

“What happens to my CCTV camera if the electricity goes off?”

The short answer? Most CCTV cameras need power to work, but there are ways to keep them running without a direct electricity supply.
Let’s break this down so you know exactly what’s possible.

1. How CCTV Cameras Normally Work

Most CCTV cameras — whether analog or modern IP cameras — require two things:

1. Power Supply – To keep the camera and its features (like night vision, recording, zoom) running.

2. Data Storage/Transmission – Either to a DVR/NVR or to cloud storage.

In a regular setup, this power comes from your home or office’s main electricity line. Without power, a standard wired camera will stop recording.

2. Can They Work Without Electricity?

Yes, but not in the usual “plug and play” way. Here’s how it’s possible:

a) Battery-Powered CCTV Cameras

Some cameras come with built-in rechargeable batteries. These can work for a few hours to several days, depending on battery size and how often the camera is recording.

• Great for temporary setups or locations without wiring.

• Examples: Many Wi-Fi-enabled smart cameras.

b) UPS (Uninterrupted Power Supply) for CCTV

A UPS is like a backup battery for your cameras and DVR/NVR.

• Keeps the system running for a few hours during a power cut.

• Ideal for places with frequent but short outages.

c) Solar-Powered CCTV Cameras

These use solar panels to charge their batteries during the day.

• Perfect for remote areas without electricity.

• Can work 24/7 as long as the battery is charged.

d) Power Over Ethernet (PoE) with Backup

For IP cameras using PoE, you can connect the network switch to a UPS or solar inverter to keep it powered.

3. Limitations You Should Know

While these options keep your cameras running without electricity, there are a few things to remember:

• Battery Life is Limited – You may still need to recharge after a while.

• Cloud Cameras Need Internet – If your internet also depends on electricity, cloud storage may stop without a backup.

• Night Vision Needs Power – IR LEDs use more battery at night, so backup time may be shorter.

4. What’s the Best Option for You?

• For Homes in Cities: A UPS is usually enough to handle occasional power cuts.

• For Rural or Remote Areas: Solar-powered CCTV is the best long-term solution.

• For Events or Temporary Needs: Battery-powered cameras are quick to set up and remove.

5. Pro Tips to Make CCTV Work During Power Cuts

• Use energy-efficient cameras that consume less power.

• Keep an extra charged battery pack for emergencies.

• Choose a DVR/NVR with low power consumption to extend UPS time.

• If using solar, ensure the panel is placed where it gets maximum sunlight.
