How Wireless Security Cameras Work

Early in the middle of the previous century when CCTV security camera was invented by Walter Bruch. The idea of closed-circuit camera invented to capture light and convert it into a video signal.

CCTV security system has many advantages, but the disadvantages of these cameras are bigger and make more problem.

As the CCTV security system use many wires and cables, Plus a DVR to process the analog signal from a surveillance cam.

Then years later, A new technology discovers to eliminate wires of Analog CCTV cameras.

This technology uses digital signals from the camera and processes it inside the camera, after that send it to NVR.

The NVR and digital security systems use fewer wires as we compared to Analog surveillance systems. In addition, reduce the cost of using more wires and cables and eliminate wiring problems.

Digital security cameras like IP security camera use Network and has many types and shapes.

The connection between other cameras it may be wired, wireless, and the last type wire-free.

In the case of wired security system, it uses one cable called PoE while wireless cameras use wifi signals to connect to NVR and other cameras.

Wired security cameras use PoE to work, but what about wireless security cameras How does wireless security cameras work?

Here’s

How Does Wireless Security Cameras Work?

In the previous lines, we mentioned that wired cameras use PoE cable to help camera send data. Plus this PoE cable is the power cable of the Digital security camera.

For wireless security cameras, it is a little different.

Wireless cameras Like IP security camera sharing data through RF signal and in most cases it uses Home Network wifi Signal.

First, the Wireless camera capture the video and maybe sound, after that the camera process the data to send it To NVR.

The NVR device uses to connect the wireless cameras to storage devices that maybe Cloud storage, Hard drive. Plus NVR allows camera owners to access and see their recorded videos.

In addition, the installation of wireless security cameras is easy, and to add more cameras to the system you don’t take too much time.

Just turn on the camera and connect it to System Network with other home cameras.

More features added to wireless security cameras, as it supports a fast connection between system devices and best cameras that connects to phone these days are wireless.

Plus, these cameras have fewer problems.

How Are Wireless Security Cameras Powered?.

For the power of wireless security cameras. Many ways used depend on the type of security camera is it wireless, wire-free.

It’s important to know that a wireless camera doesn’t mean it’s literally wireless, the wireless word describes how the security camera shares data.

But for the power, it’s different a little bit.

How Are Wireless Security Cameras Powered

4 methods used to power wireless security cameras.

  1. Wired security cameras Powered With PoE: This type of wireless camera uses a PoE(power over ethernet cable) which means the camera uses the same cable for data and power.
  2. A wireless security camera with Plug: In this case, the wireless camera has a Plug and must be mount and install near the Electric outlet.
  3. A wire-Free security camera with Battery: The Wire-Free security camera means no wired used with the camera. In this type a battery used as a power source for the camera and in most cases this camera is rechargeable.
  4. A wire-Free security camera with Solar Panel: Another way used differently from batteries is Solar Panels. A Solar panel used with wire-free cameras to provide power and this method are common in outdoor surveillance systems.

These are the four methods for How are wireless security cameras powered. And it’s important to know which type you will use before purchase a security camera.
