IP surveillance cameras connect to the network using an Ethernet cable or a wireless connection. Wireless IP cameras are convenient because they can be installed anywhere without running cables. Still, they are more expensive than wired cameras and may have a shorter range and poorer performance. Ethernet is the best choice for most small-scale installations because it is more reliable and accessible to troubleshoot than wireless. A wireless system may be the best option if you need to install cameras in a large area or where wiring may be complex.
