OVC and the Spy shop both sell systems that record to Dvds. Some systems are motion detection activated, so you are only recording when the unit picks up something moving. Electricity in our area to run the system is about 5 cents an hour when it is in operation. If you have the type of system you are speaking about, use a backup battery and turn the monitor off and it is not that expensive.
