I’ve installed WiFi cameras, PoE cameras, solar-powered cameras, 4G cameras, and all kinds of other cameras. Which one is best for you? Basically, security cameras all serve the same purpose—monitoring and recording—and the only difference lies in their systems. I refer to PoE cameras as IP cameras, since PoE stands for Power Over Ethernet. Meanwhile, WiFi cameras are those whose systems connect to a WiFi network.
To help you better understand PoE cameras and WiFi cameras, in this article I’ll explain them based on my own experience.
What Is a PoE Camera? How Does It Work?
In my experience, PoE cameras are a type of IP camera.
These cameras use a single cable—a LAN cable—for both power and data transmission. Therefore, this camera does not require a separate power cable. Power is supplied directly to the camera from a PoE device, commonly referred to as a PoE adapter or PoE switch. Power can also be supplied directly to the camera from an NVR that supports PoE. An example of a PoE camera is the HiLook D121HE-UC.
To make it easier to understand, I’ve included a wiring diagram for a PoE camera below.

Pros of PoE Cameras
- Easier Installation Compared to Analog Security Camera
- Reliable Connection
- Higher Video Quality
- 24/7 Recording
- Perfect for Large Properties
Cons of PoE Cameras
- More Involved Setup Than WiFi Cameras
- Professional Setup May Be Required
- Limited Flexibility in Camera Placement
- Higher Upfront Cost
PoE cameras are generally sold as kits. A single kit may contain 4 or 8 cameras. An example is the Eufy PoE NVR Security System E41.
What Is a WiFi Camera? How Does It Work?
The WiFi camera connects directly to the internet without a cable.
Even though it’s wireless, you’ll still need to set up a power source where the camera will be installed. WiFi cameras are typically powered by an adapter that plugs into an electrical outlet. There are also WiFi camera options that use batteries and solar panels. These can be installed without requiring a power source because the camera runs on batteries. WiFi cameras connect directly to your phone and don’t require a recorder like an NVR.
Here is the wiring diagram for the WiFi camera:
Pros of WiFi Cameras
- Easy Installation
- Flexible Placement
- Remote Access
- Integration with Smart Home Devices
- Lower Initial Cost
Cons of WiFi Camera
- Dependent on WiFi Signal
- Battery Dependency (for Wireless Models)
WiFi cameras are generally sold individually. I’d say there’s a wider variety of WiFi cameras compared to PoE cameras.
My Review of PoE Cameras and WiFi Cameras—Which Should You Choose?
First, I’ll explain about PoE cameras.
PoE cameras are ideal for use in almost any building, from hotels, hospitals, and private homes to large-scale locations such as coal mines and factories. PoE cameras offer more stable connectivity because they use a cable connection to the NVR. I have yet to come across a situation where more than two WiFi cameras were installed in a large area like those mentioned above, due to connectivity limitations.
PoE cameras cannot connect directly to WiFi, but they can still be connected to the internet using an Ethernet cable connected to a router.
Next, an explanation of WiFi cameras.
This camera can be connected directly to a smartphone and to WiFi. It does not require a recorder or a monitor. Generally, WiFi cameras use memory cards as their storage medium. The memory card is installed inside the camera. To view the camera’s live feed, users can access it from their smartphone using the app provided by the manufacturer.
WiFi cameras typically come with additional features such as alarms and human detection.
So if you need a security camera to monitor a large area, you can use a PoE camera, as it offers superior connectivity. Meanwhile, if you only need a camera to install at home and have a WiFi network available, you can choose a WiFi camera. In addition to being easy to install, WiFi cameras come with smart features such as motion detection and alarms, which are essential for home surveillance.
Can I Use a WiFi Camera and a PoE Camera Together in the Same Location?
A WiFi camera is actually a type of IP camera as well; the only difference is that it can connect directly to a WiFi network. Therefore, WiFi cameras can be used alongside PoE cameras.
One example is the EZVIZ camera.
I can connect an EZVIZ camera to a PoE camera system. However, this is contingent on there being available channels on the PoE network video recorder (NVR). Since EZVIZ cameras support ONVIF, you can connect them to any brand of NVR as long as that NVR also supports ONVIF. For your information, generally all NVR brands currently available on the market support ONVIF.
Frequently Asked Questions (FAQs)
What is a PoE Camera?
A PoE camera is a security camera that uses a single LAN cable for both power and data transmission.
Should I Buy a WiFi Security Camera or a PoE Camera?
It really depends on your needs. If you have a very stable Wi-Fi network at home, a Wi-Fi camera might be a good choice; however, if that’s not the case and the area you need to monitor is larger, you might want to choose a PoE camera.
What are the Disadvantages of PoE Cameras?
It costs more than a Wi-Fi camera. Installation requires a professional camera technician.
What is the Difference Between a PoE Camera and a WiFi Camera?
One very noticeable difference is that PoE cameras require an NVR to display video on the camera screen. WiFi cameras connect directly to the WiFi network, do not require a recording device, and connect to a smartphone.
Final Thoughts
After reading the explanation I wrote above, you should now be able to decide which camera to choose. Both PoE cameras and WiFi cameras are good options. Your task now is to choose the camera that best suits your needs. If you want a camera with reliable connectivity, a PoE camera is the solution. If you want a camera that’s easy to install and has many features, a WiFi camera is the way to go. In any case, both types of cameras require an internet connection so they can be monitored remotely from your phone.
