Wired vs. Wireless vs. Wire-Free Security Cameras
Although the names may be intuitive, there are distinct differences between wired, wireless, and wire-free security cameras.
Lets break down what each of these mean so you have a better understanding of what type of system might work for you.
Wired security cameras are the most traditional type of surveillance camera. Wired cameras are directly connected (wired) to a recorder (DVR or NVR) which connects to a monitor or tv. You are able to view live video or playback video, which is displayed on the monitor or tv. If you have Internet, the system can be connected and you can download an app on your phone. This app will allow for remote viewing, anywhere at anytime, from your smartphone, laptop or tablet. Wired cameras typically use either a BNC cable or Ethernet (POE) cable. These cables provide the video as well as the power to the cameras. Wired security cameras require the installation of cabling to connect each camera to the recorder and work with or without WiFi.
Wireless - A common misconception is that wireless also means it’s wire-free. That is not 100% true as wireless means the video is sent over WIFI, but a power cord is still needed at each camera location. Usually a power adapter with 6-10 feet of cable is plugged in to the camera to power it. This is a great option for a location having internet/WiFi and doesnt require running cabling to each camera. But, power is needed at each camera location which is sometimes not possible. Wireless security cameras require power at the camera and a WiFi router in order to work.
Wire-free security cameras are just that, absolutely wire-free. The cameras are battery powered and require periodic charging. The amount of time between chargins depends greatly on camera location. A camera pointed at an area traveled heavily by pedestrians or vehicles will need charged much sooner than a camera pointed in a storage closet with virtually no activity. Wire-free security cameras are the easiest to install, and security footage is stored on an SD card which can be retrieved to transfer video/photos. Many camera manufacturers also offer cloud storage which can be free or have a monthly/yearly fee. Wire-free cameras may not be a good option if the cameras will be in hard to reach places, making it difficult to get to the batteries. Solar panels are an option with some cameras depending on the brand and location the camera will be located. The panels keep the battery charged which are a good option for the hard to reach camera locations.
