2. Reset the CCTV Camera – Step-By-Step Way

Resetting a CCTV camera can be useful in various situations. Here is a step-by-step way to reset the CCTV camera.

Locate the Reset Button

Most CCTV cameras have a small reset button that is usually located either on the camera itself or on the back of the device.

It is typically a tiny hole that can be pressed using a pointed object such as a paperclip or a pin.

Press and Hold the Reset Button

Once you have located the reset button, press and hold it for approximately 10-15 seconds.

Make sure to exert enough pressure and maintain the hold until you see the camera’s indicator light start flashing or hear a beep sound. It indicates that the reset process has begun.

Configure the Camera

After resetting the CCTV camera, it will revert to its default factory settings. You will need to reconfigure the camera by following the manufacturer’s instructions.

It usually involves;

  • Connecting the camera to a power source and a monitor or a computer
  • Accessing the camera’s settings interface
  • Setting up the desired parameters such as network settings, motion detection, and recording options.

By following these steps and taking appropriate precautions, you can quickly restore your CCTV camera after a power cut.

Frequently Asked Questions FAQs

Does CCTV camera work after power cut?

Yes, CCTV cameras are designed to resume operation after a power cut.

Most CCTV systems have a backup power supply, such as a battery or an uninterruptible power supply (UPS), which ensures continuous functioning even during power outages.

These backup power sources provide temporary electricity to the camera system, allowing it to continue recording and monitoring the area until the main power supply is restored.

Why CCTV camera suddenly stopped working?

There can be several reasons why a CCTV camera suddenly stops working.

One common cause is a power issue, such as a blown fuse, a tripped circuit breaker, or a faulty power adapter.

In such cases, it is essential to check the power source and connections to ensure they are intact and provide electricity to the camera.

Another reason could be a network or connectivity problem. If the camera is IP-based, issues with the network or internet connection can disrupt its functioning.

Additionally, physical damage, extreme weather conditions, or software glitches can also lead to sudden camera failure.

What can damage a CCTV camera?

CCTV cameras are generally built to withstand various environmental conditions, but they can still be susceptible to damage.

Extreme weather conditions, such as heavy rain, snow, or excessive heat, can cause damage to the camera’s housing, lens, or electronics.

Vandalism or physical impact, like a direct hit or intentional tampering, can also harm the camera.

Furthermore, power surges, electrical fluctuations, or improper electrical connections can potentially damage the camera’s internal components.

It is crucial to install cameras in suitable weatherproof housings and ensure proper electrical connections to minimize the risk of damage.

Where is the reset button on CCTV camera?

The location of the reset button on a CCTV camera can vary depending on the camera model and manufacturer.

In most cases, the reset button is located on the camera’s main body or near the wiring connectors.

However, it is important to note that not all CCTV cameras have a physical reset button.

Some cameras may require a specific sequence of button presses or a software-based reset through the camera’s configuration interface.

To find the exact location or method for resetting a specific camera model, it is best to refer to the camera’s user manual or contact the manufacturer’s customer support.

Do cameras have a reset button?

While many CCTV cameras do have a reset button, it is not a universal feature. The availability of a physical reset button depends on the camera model and manufacturer.

Some cameras may only offer a software-based reset option through their configuration interface, while others may have a combination of both.

It is important to check the camera’s documentation or contact the manufacturer to determine whether a specific camera model has a reset button and how to use it effectively.


In conclusion, if your CCTV cameras aren’t working after a power cut, there are several common reasons and solutions to consider.

By following the above troubleshooting steps, you should be able to identify and resolve most issues with your CCTV system after a power cut.

However, if you continue to experience problems, it’s recommended to consult with a professional technician who specializes in security camera systems for further assistance.
