CCTV cameras have become a necessity in modern security. Therefore, it is important to choose the right CCTV camera for your needs. That said, one of the major concerns people have about these security devices is whether or not they function during power cuts or outages. This is because although we do not have regular power cuts, they still occur during times of heavy load, heavy rain, storms, and during repairs of local electrical outlets. If your CCTV system depends entirely on electricity, what actually happens when the power goes out?Does CCTV work without electricity, or is there a way to keep them running? The simple answer here is that CCTV cameras do not work without electricity. However, when people ask these questions, they do not mean electricity but rather the main power supply. Regardless, do they still work without the mains power? When presented like this, the answer changes as there are CCTV cameras that do work without mains power.
In this blog, we provide you with insights on CCTV cameras that work without electricity – or mains power in this instance.
Does CCTV Work Without Electricity?
The simple answer to the question of “Does the CCTV work without electricity?” is no – they do not. Regardless of the type or model of CCTV camera, they need electricity to function. However, there is a catch, as depending on the type of camera, they do not need to be connected to the main power in any way to work as intended. In fact, besides wired CCTV cameras, most other types of CCTV cameras do not depend on the mains power.
Wireless CCTV cameras rely on multiple means, battery-powered CCTV cameras rely on their internal battery, and solar-powered CCTV cameras rely on either built-in solar panels or are connected to solar panels to function.
That being said, although the cameras themselves do not rely on mains power, their other components, such as DVR, NVR, router, and monitor, mostly do rely on electricity. Therefore, it is always a good idea to keep a power backup for the components.
In summary, the answer to the question of “Does CCTV work without electricity?” is that CCTV cameras cannot operate without electricity, but they can without mains power. However, although the camera itself may not be dependent on mains power, its additional components are.
What Happens During a Power Cut?
Since we have established that many types of CCTV can work without mains power, the next question that often comes to mind is – what happens when the mains power is cut? There are four scenarios that occur when the power is cut. They include:
Cameras stop recording
If your surveillance camera directly takes power from the mains power line, then it immediately stops recording. They will resume recording once the power is back, but there will be a gap in recording during the outage. This is not much of an issue for wireless, battery-powered, or solar-powered cameras, though, so as long as you have the right camera, you still get continuous recording.
Live monitoring gets interrupted.
Although wireless and cameras that do not rely on mains power can continue recording without the power, during a power cut, the majority of live monitoring gets interrupted. We say the majority of live monitoring since we can now have live recording on mobile devices such as smartphones or tablets. As long as the camera and the device stay on the network, you can still monitor the footage live. But many places still rely on traditional monitors, DVRs and NVRs. If you have a surveillance system with these setups, when the power gets cut, they get interrupted.
Stored footage remains safe (if the system is intact)
The good news is that previously recorded footage is usually not lost. CCTV systems store data on hard drives (in DVR/NVR) or cloud storage, and this data remains intact as long as the system is not physically damaged or corrupted. Once the power returns, your system will resume normal operation, and you can access past recordings without any issue.
Types of CCTV cameras and their power requirements
At this point, we have already established that not all CCTV relies on mains power. Their requirements also vary based on their type. Therefore, by learning their differences, you will be able to pick the best one for your house, especially if you live in an area where you often face power outages. Some of the main types of CCTV cameras based on the need for electricity are:
Wired CCTV Cameras
These are the most commonly used CCTV cameras for domestic and commercial purposes. Wired CCTV cameras are connected to a power source.
These cameras need a constant electricity supply to operate. When the power goes out, both the camera and the recording system stop working immediately. Without any backup like a UPS or inverter, wired systems cannot record or transmit footage during outages.
Wireless CCTV Cameras
Wireless CCTV cameras reduce the need for video cables, but they are not completely wire-free. They still need power, which they get through an adapter or built-in battery.
Most wireless cameras depend on electricity for continuous operation and also require a stable internet connection for remote access. During a power cut, they stop working unless they have a battery backup. Even then, features like live viewing may not work if your Wi-Fi router loses power.
Battery-Powered CCTV Cameras
Battery-powered CCTV cameras come with built-in rechargeable batteries, allowing them to operate without direct electricity for a certain period. These cameras will keep recording even during power outages. Therefore, they are a good alternative as a backup. Nevertheless, they will run out of power depending on the battery. You should charge the camera frequently. In addition, excessive usage of the camera, such as continuous recording, will reduce the battery life.
Solar Powered CCTV Cameras
Solar-powered CCTV cameras make use of a solar panel to produce power and charge their internal battery. Therefore, they are best used in areas where the power supply is not reliable or is absent. They can work independently of the power supply as long as they are receiving sunlight. In addition, most of the solar-powered cameras are equipped with a battery to allow them to work at night or during cloudy weather.
How to keep CCTV working without electricity ?
Even if the main electricity supply is cut, your CCTV system can continue to work. You can maintain your CCTV system even if you lose electricity. These are the most efficient options:
Uninterruptible Power Supplies (UPS)
A UPS is an easy way to protect a CCTV system against power surges. A UPS instantly supplies backup electricity the moment power is lost, so cameras and recording devices can continue to function without interruption.
A UPS is the best option for short-term interruptions. The capacity of the UPS system can allow your CCTV to run for anywhere from 15 minutes to several hours. This will prevent any security gaps that may occur and allow your system to shut down safely, if necessary.
Use backup batteries and inverters.
Inverters with batteries are a better backup than UPSs. When power fails, the inverter keeps your CCTV system going by using the stored energy in the battery.
This setup can support cameras and DVR/NVR for several hours. It is a great solution for areas where there are frequent or prolonged power outages. To work properly, you will need to install it correctly and perform occasional battery maintenance.
Solar Solutions – Using Power Systems
Solar power is a reliable and sustainable solution. They store electricity in batteries and generate it through solar panels. Your CCTV system will continue to work even without grid power.
