NVR or network video recorders record video data created or "encoded" by network security cameras( also known as IP cameras). NVR uses two main types of IP cameras:
1. PoE cameras are wired IP cameras that provide power and data using Ethernet or network cables.
2. Wireless IP cameras (also known as WiFi security cameras) typically require power and wireless connection to the WiFi network.
Ethernet power cameras provide maximum convenience because they receive power and data connections over a single cable. PoE does not need to use power nearby and does not rely on intermittent wireless connections. Another convenience when purchasing compatible devices is the plug-and-play feature, which is common in IP camera systems. Plug-and-play compatibility makes installation and configuration easy. This is because the plug-and-play system is automatically configured with an IP camera to connect and record to the NVR system.
Wireless IP cameras provide some convenience, but are not reliable for professional surveillance systems. The wireless camera works by having power nearby and using a WiFi radio to connect to a wireless router or network. While the prospect of using a wireless or WiFi security camera may sound encouraging, it is fraught with limitations and maintenance requirements.
Wireless security cameras are useful, given their usage restrictions. For homes up to 2,400 square feet with some warnings, you can definitely use a 4-camera wireless security camera system:
Wireless is also useful for wired scenes that are impossible or too expensive. For example, if you have a parking lot with a parking lot that requires a security camera, it might be easiest to deploy a wired IP camera paired with a WiFi access point to make it wireless. Although the cost is high, the results are impressive. We recommend that you read the guide on how to make a wired camera wirelessly connected to learn more.
An IP camera is a smart camera that contains advanced hardware for capturing and encoding video. This means that IP cameras can also be used as stand-alone cameras, some of which support internal microSD cards for local recording. Advanced hardware also supports updates such as video analysis, noise reduction and other image processing adjustments.

Wireless security cameras are useful, given their usage restrictions. For homes up to 2,400 square feet with some warnings, you can definitely use a 4-camera wireless security camera system:
- The camera needs to be connected to a nearby 110V AC power outlet to provide continuous power supply
- WiFi signal path from router or WiFi access point cannot exceed 250 feet (clear line of sight)
- The WiFi signal arriving at the camera should be 90% of the signal strength. You can use your smartphone to check WiFi strength at a location, as described in our guide on how to use a wireless surveillance camera with a WiFi router
