With the popularity of IP cameras increasing and the price dropping I'm left wondering.
I myself still use the old style x10 cameras and equivalents but I've started to add IP cams to my remote Log home.
I've not compared the power consumption but I'm fairly certain the IP cams will in the end win out as fewer items need to be powered.
Something that is a concern for me with the off grid cottage.
Just not having to have a PC running there 24/7 is a real bonus.
