Wi Fi security camera systems send footage from cameras placed around the house to the home’s Wi-Fi.

The transmission is completely wireless.

Once the Wi-Fi receives the signal, it is sent to a cloud server, where footage clips can be viewed in real-time or it is archived for later viewing. Some cameras have onboard micro SD cards which store a limited amount of footage.

Standard features to expect in wireless and wire-free security camera systems include night vision, two-way audio, 2K HD video, and voice control through your choice of digital assistant (such as Amazon Alexa or Google Assistant).

By contrast, Wi-Fi systems receive constant power from the home and are capable of recording small video clips as they usually are storing footage in the cloud. They can also be set to record only when motion is detected. (Not 24/7 recording)

Advantages of Wifi Security Cameras

Wifi security cameras are less invasive to your home than wired cameras, so they set up easier and faster. - (Power Wire is still Required on most wifi cameras)

Wifi cameras also are more flexible than wired systems because they aren’t as tied down by wires. The cameras can easily be rearranged.

If there is a clear line of sight—such as between an outbuilding and the main house—wireless outdoor security cameras may have a range of up to 500 feet. - Mesh Wifi extender suggested on larger homes or business applications

Disadvantages of Wireless Security Cameras

Wifi security camera systems work well as long as the wifi signal from the cameras is clear and uninterrupted.

Within the home,Wifi systems usually have a range of about 150 feet or less. The wireless signal passes through walls made of drywall and wood studs. But denser building materials like brick or concrete blocks can impede the signal.

Wifi cameras that plug into wall outlets can present an issue because each camera must be situated near an outlet.
