Wireless Security Cameras in a Nutshell

So, how does a wifi security camera work? In short, a wireless camera captures video data and then translates it via an RF or radio transmitter. These cameras sent video data to a receiver connected to some built-in storage device. For an additional cost, you can have video stored in the cloud. For output, you can have a monitor connected to a receiver. It gives access to images or video clips. 

Most wireless security cameras receive and send data via incoming and outgoing messages. For example, you offer some commands to a camera, such as changing its field of view or altering a motion sensor. In turn, an outgoing message is sent by a security camera. It can be a livestream to your smartphone or transmission to some professional monitoring system. 

Wired vs. Wireless

Original security cameras required some type of electrical source to work. For example, these wired security cameras use video cables to transmit signals to a receiving device. In contrast, wireless security cameras do not need cables to transmit video and audio signals. In short, these cameras use the following wireless technologies:

  • Wi-Fi. You can use a home Wi-Fi network to handle incoming and outgoing messages. In addition, a Wi-Fi connection can be used to store a video signal in the cloud or send it to local Digital Video Recorder (DVR) units.
  • Bluetooth. Bluetooth works on the same frequency as Wi-Fi. However, this wireless technology connects the receiving devices via star topology. Therefore, Bluetooth connection works on short distances. 
  • Cellular. Some wireless security cameras rely on cellular networks. Most often, cellular works as a backup for Wi-Fi networks.
  • Z-Wave. Engineers developed this technology to work with smart technologies. Yet, Z-Wave does not have enough bandwidth to transmit video data. So, this wireless technology is used to connect different parts of your home security system.

There is an ongoing debate concerning wired and wireless cameras. On the one hand, wired security cameras cannot be jammed and offer crystal-clear video output. On the other hand, wires are messy, and you cannot transmit video outside your home. It is safe to say wireless technologies will soon make wired cameras obsolete. 

Advantages of Wireless Cameras

Now, we know how wireless cameras work. We also know they are better than wired cameras. Next, let’s find out the particular advantages of Wi-Fi cameras, which are the following:

  • Easy installation

  • Brick and concrete walls can impact the strength of the wireless signal.
  • Wireless cameras need a lot of bandwidth to transmit high-resolution images and video clips. It means you need to have a strong Internet connection at all times.

Ensure you have a good Internet connection and the router is near the camera. Besides, if you have brick or concrete walls in your house, install a wireless security camera in direct sight with a router, if possible.
