PoE cameras are growing in popularity as they offer a convenient and cost-effective solution for powering IP cameras. But do PoE cameras require a power supply? The short answer is no, but there are a few things to consider before ditching your camera’s power adapter.
In this blog post, we’ll explore whether PoE cameras need a power supply and what factors you should consider when making the switch to PoE power.
1. Power over Ethernet, or PoE, is a technology that allows network cables to deliver both power and data to devices such as IP cameras. This means that you only need to run a single cable to each camera, which can simplify installation and reduce costs.2. However, not all PoE cameras are created equal. Some models require an external power supply, while others can draw power directly from the PoE cable. Be sure to check the specifications of your camera before making a purchase.3. If you’re not sure whether or not a PoE camera is right for you, our experts can help.

How do you power a PoE camera?
What is needed for PoE 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. 
Here’s how to use a PoE switch with PoE security cameras: Plug the PoE switch into a wall outlet or surge protector using a 110-220VAC power cord. If the PoE switch has an external power supply, plug the power supply into an outlet, and connect the other end of the external power supply into the PoE switch.1 Mar 2021 
Two things are needed to use PoE: a camera designed to receive power through the RJ45 connection and a device to inject power into the cable. This can be done by the network interface card (NIC) in a PC or by a network switch or bridge. 
As it turns out, PoE cameras do in fact require a power supply. However, there are a few options available that can help to make the process a bit easier. For example, there are PoE injectors that can be used to provide power to the camera without the need for an additional power supply. There are also PoE switches that can be used to provide power to multiple cameras at once. Ultimately, the decision of whether or not to use a PoE camera will come down to personal preference and the specific needs of the application.
