We suggest the closer the better. The camera comes equipped now with 25 feet of ethernet cable. If you need more than 25 feet from modem we include a connector piece that must be covered by duc tape and kept waterproofed as much as possible. Another ethernet cord can be added but our recommendation is not over 150 feet. The longer the connection the less direct speeds we can achieve.
We suggest to install a switching station near the camera for the best possible connection. We also include a small white box where the cord from the modem to the ethernet cord is connected to a port on the modem with another space for the power cord.
