Their functionality has also changed. Their use has increased in many homes and offices, but how did this happen? Let's look at some of the major advancements made to wireless doorbell cameras over the years.
When the first wireless doorbell cameras were created they were simplex systems that consisted of a single camera fixed to a door knob. The video from this camera was then sent to a receiver that was positioned either inside or outside the home or office building. This system worked okay, but it lacked something. It couldn't send the video signals if the door or window was closed.
When wireless doorbell cameras started to be introduced into the marketplace, they started to have video sensors that could detect when the door or window was opened. These wireless devices then needed to be positioned inside or outside the home or office building for the same reason. If there was no motion detected from the camera the signal was dropped. But there was an option that was added to the wireless doorbell cameras to allow them to be set up in many more places.
This option is commonly referred to as WUSB. This stands for "wireless doorbell cameras using USB." The way that this works is that the wireless doorbell cameras can be put into several different locations and still receive the same video signal. They are still able to transmit the signals to the receiver. This gives the wireless device flexibility because there are no physical wires to connect to. It also makes it much easier to relocate the wireless doorbell cameras to new areas if necessary.
