If you have a CCTV system installed at your home or business, it’s important to know how to reset it after a power cut.


In this guide, we discuss how to reset your Closed Circuit Television (CCTV) after a power cut.

Power cuts can cause your CCTV system to become unresponsive and inoperable if it isn’t rebooted correctly. A CCTV system typically contains a central unit that is connected to video cameras included with the system; however, some systems are sold as a single architectural unit. To properly reboot your system, you need to turn off the power at the mains, disconnect all the cables from the back of the main unit, then turn the mains power back on again and reconnect all cables. It is important that you follow these steps in order so that your CCTV system is restored correctly and continues to operate reliably.

It is also important to be aware of any warranties associated with your CCTV system; resetting it can sometimes lead to voiding a warranty which would mean any costs incurred for repair or replacement would not be reimbursed. In addition, some manufacturers may require that homeowners or users contact an authorized technician before attempting a full operating system reset on their own as this can sometimes have undesirable consequences if done incorrectly or without enough knowledge about how systems work.

Check the Power Source

After a power cut, it is important to check the power source of your CCTV system before attempting to reset it. You should also check for any visible damage to the device. If your CCTV is powered through an adapter, you should check for any signs of wear and tear on the power cable , as well as check the socket for any tripping of the circuit breaker. It is important to ensure that there is no fault in the power source before attempting to reset the CCTV.

Check the power supply

After a power cut, it’s important to check the power supply of your CCTV system before carrying out any further procedures. This can help avoid unnecessary repairs and maintenance costs, as well as reduce the possibility of future malfunctions.

The CCTV unit should always be connected to a dedicated power source in order to keep the system running efficiently and without interruption. To determine if your CCTV has a stable connection, first inspect the power supply cords for any signs of physical damage or deterioration due to age or general wear and tear. If possible, check if there are any loose connections that could be causing an intermittent power supply.

Secondly, examine the cables used for the CCTV connection – often coaxial or network – for signs of damage. If these cables are not properly attached to their corresponding ports, they may not be adequately supplying electricity to your security camera system.

Finally, take note of any receptacles or surge protection devices that may have been installed alongside the power source in order to protect against spikes in voltage or current flow interruptions. These devices should be checked regularly in order to ensure that they are functioning properly and providing adequate protection against unforeseen electrical problems. Once you have confirmed that all components necessary for proper operation are hooked up correctly and in good working condition, you can reset your security camera system safely with confidence!

Check the cables and connections

After the power has been restored, it is important to ensure that all of the cables and connections are secure. Start by inspecting any visible external cables such as AC Adaptor and Power In/Out cables, video connection cables and coaxial cable. Pay special attention to any jumper/patch leads between CCTV components.

The next step is to check the power supply panel. This can be complex so if you do not feel confident doing this yourself, please consult a professional. It may be necessary to check all of the switches, fuses and terminals lines in order to make sure that everything is in correct working order before attempting to reset your CCTV system.

In addition to checking the power source itself, it’s also important to check any additional equipment such as surge protectors or UPS (uninterruptible power supply). These devices can help protect your CCTV system from further fluctuations in electricity after a power cut.

Reset the CCTV

Resetting your CCTV after a power cut is an important precaution to ensure that your system is up and running as quickly as possible. Depending on the CCTV system you have installed, the steps for resetting can vary. In this guide, we will cover all the necessary steps for resetting a CCTV after a power cut, so you can get your system back up and running in no time.

Unplug the power supply

Before resetting the CCTV after a power cut, it is important to unplug the external power supply from mains, wait for 30 seconds and then plug back in to restore the power. This allows all elements of the system to resume normal functioning. Additionally, if your CCTV system is struck by lightning make sure that you unplug its connection with other components as well and do so as soon as possible in order to prevent any major damage caused due to lightning strikes. While it is a good practice to get a professional technician examine the unit for any permanent or irreparable damages inflicted due to lightning strikes, generally unplugging should reset most of these systems after a power cut or worse case scenario—lightning strike.

Wait for a few minutes

When the power is cut to your CCTV, it’s important to wait for a few minutes before you attempt to reset the system. By waiting, you’ll ensure that the system won’t be damaged due to a sudden surge of electricity or an imbalance of power. Additionally, as some CCTV units need a certain level of power supply maintenance, such as standby batteries or UPS systems, it can take a few moments for these components to prepare the unit ready for reactivation. Once you are certain that enough time has passed and your CCTV unit is ready, then you can turn it back on and proceed with the steps below.

Plug the power supply back in

Once you have successfully switched off and on again the mains switch supplying power to your CCTV system and completed any necessary data backup, unplug the power supply. Then wait for at least 5 minutes before plugging it back in. This allows for any stored electric energy in the system to be discharged, allowing for a clean restart of the security camera system. Reseating the connected cables can also help to remove any trace voltage from them and ensure that everything is safe from electrical hazards.

Check the Settings

When your CCTV system has been affected by a power cut, it is important to check the settings before resetting it. To avoid any sort of data loss or any other issues, it is best to check the settings of your CCTV system to make sure that they are in the right state. This will help you identify any problems that may have occurred during the power cut, such as the incorrect settings or hardware failures. Let’s take a look at how to reset your CCTV after a power cut.

Check the settings on the CCTV

Before resetting a CCTV after a power cut, it is important to check the settings. Once power has been restored, check the Network or Service settings first. This should include the Internet Protocol (IP) address, the Domain Name System (DNS) server information and whether or not you have a router connected to the network. In addition to checking these settings, make sure that your Security Settings are enabled and properly configured as this is necessary for your system to function properly.

Next, check your Video Settings such as the number of frames per second (FPS). If they have been set too low, you may experience video flickering or graininess when recording video footage. Ensure that the number of FPS is set correctly before proceeding with any further adjustments. Additionally, make sure that other video settings such as image brightness, sharpness and contrast are adjusted correctly too.

Finally, check camera angles and angles of sight so that all blind spots are visible on camera recordings. This step also ensures that all sensitive areas of your property are adequately monitored by CCTV cameras. Once all settings have been checked and adjusted accordingly if necessary, you may now reset your CCTV system after a power cut.

Make sure the settings are correct

When power is restored to a CCTV system, some camera settings may have reset or may need to be adjusted. It is important to check the settings of each camera, monitor and DVR carefully. Depending on your system configuration, you may wish to adjust the recording settings, resolution and frame rate – as well as any other settings that were active before the power cut occurred.

It is also recommended that users test functionality of hardware components such as cameras and monitors by using built-in diagnostic tools such as watermarking tests or picture-quality tests. This helps ensure that all necessary parts are working properly before returning the CCTV system to full operation. To maximize user satisfaction and system performance, use only original equipment replacement parts for any repairs or replacements needed during the reset process.


After a power cut has caused your CCTV system to reset, it is important to take the appropriate steps to ensure that the system is fully operational again. First, check if all components have the correct connections. Second, test each of the components to make sure they are all powered and working correctly.

Next, format or reset your DVR depending on what model you have. Finally, access your CCTV’s set up network and apply any needed changes or settings necessary for the system to function properly again. By following these steps, you should be able to get your CCTV system up and running correctly with minimal effort.
