There are a few key differences between wired and wireless security cameras. Perhaps the most obvious is that wired cameras need to be physically connected to your home's electrical system, while wireless cameras run on batteries or can be powered by solar panels. Wired cameras are also generally more reliable than wireless cameras, since there's no chance of a weak signal or interrupted connection. However, wired cameras can be more difficult to install, and they often require drilling or running wires through your walls. Wireless security cameras are much easier to install, since you don't need to worry about wiring. They're also more flexible in terms of placement, since you can put them anywhere that has a good signal. However, wireless cameras can be more prone to signal interference, and they may not be as reliable as wired cameras. Ultimately, the choice between wired and wireless security cameras depends on your specific needs. If you want a reliable and easy-to-install camera system, wired cameras are probably the way to go. If you need more flexibility or don't want to deal with the hassle of wiring, wireless cameras might be the better option.
