How Do Security Cameras Get Power

How do security cameras get power? There are various types of security cameras on the market with distinctive ways of power supply, like the most popular wireless security cameras, wire-free CCTV cameras and PoE cameras. It can be difficult for you to tell how they actually get power by names. Follow this post and gain some professional insights into the power supply for security cameras to avoid some common misunderstandings.

How Do Wireless/Wi-Fi Security Cameras Get Their Power

Do wireless security cameras work without power cords?

It depends on the type of wireless security cameras you refer to.

Actually, there are three power sources for wireless security cameras and it divides them into three different types.

Option 1: Wireless Security Cameras That Need to be Plugged in

When we talk about wireless, it generally means that the data transmission is wireless from the camera to a receiver (a DVR/NVR or monitor). That’s to say, you still need a cable for power and you have to plug it into an electrical outlet – that’s how wireless security cameras get power.

Therefore, if you are going to power a wireless or Wi-Fi security camera outside, you should consider the distance between the wireless security camera and its power source.

Note: You can also learn how to run power to wireless security cameras for your front door, backyard, bedroom, garage, warehouse, basement/parking lot, farm, entrance, or upstairs quickly and easily.

Option 2: Wireless Security Cameras That Are Battery Powered

The battery-powered wireless security cameras get their power with NO wires at all, which is a truly wire-free security solution.

It needs no cable for both data transmission and power supply. Just as the name suggests, it operates on batteries and hence does not need an additional electrical power source.

However, the battery life may be the major concern that prevents you from grabbing a camera of this kind. Actually, the battery issue is easy to deal with.

Here is the thing: the battery-powered cameras will only wake up when motion is detected which saves battery life, and there is no need to worry about the security cameras power outage since you will be reminded of how much power the security camera uses via the software.

Option 3: Wireless Security IP Cameras That Are Solar Powered

Solar-powered security cameras are another choice for wireless security cameras without an actual power cable.

Generally, they are sold separately, but you can easily get a set from the same manufacturer. And the above mentioned Reolink Argus 3 Pro also supports solar power and ranks among the best in its league.

How Do PoE/Wired Security Cameras Get Power?

Are the wired security cameras truly inferior to the wireless ones in wiring, especially for power?

The answer is NO which may be a surprise to some. Actually, wired doesn’t necessarily mean extra cabling work if you choose the right camera: PoE (Power over Ethernet) security cameras.
PoE security cameras get power and transmit data via only one Ethernet cable.

That’s to say, all you have to do is wire up the network, and there is no need to find an electrical outlet for power delivery. Powered by the common Cat5 or Cat6 cable, the PoE security cameras are easy to set up even for beginners.

This kind of power supply could save you a lot of trouble since the network cables do not need a qualified electrician to fit them and the camera’s placement will not be restricted by the power source, and of course, there will be no overload and underpower issues which are common in the electrical cable.

The PoE camera also gains advantages in the multi-camera power supply. Instead of having to find an electrical power outlet for every camera of your security system, a PoE switch could have no trouble accommodating at least 8 PoE security cameras with a simple cable connection.
