Our 4 channel security camera systems will allow you to connect and record up to a maximum of 4 IP cameras however some systems may include less than 4 cameras. When shopping It is essential to be aware that the channel number of a system indicates the maximum number of cameras that can be connected and recorded on that system. You will never be able to connect or record more than 4 cameras on a 4 channel system. So if you think you may possibly need more than 4 cameras in the future then you may want to consider purchasing an 8 channel system instead.
