I also thought about getting a separate wireless router that will allow me to throttle speeds and blocks access to known illegal sites.

Went to visit the property for the first time last week and found out it had a large wireless internet tower owned by a large operator.

It has build in wired and wireless network.

For cable, go wireless - one transmitter and 2 receivers.For internet, go wi fi with three secure SSID accounts - one for each unit.Big savings!

I haven't looked into it deeply, but I'm sure there are wireless ones that will send you an email every so often :)

Must have wireless connection.

If this is an existing building, I would suggest looking into detectors that can be interconnected wirelessly (they are pretty new, I think first alert is a brand that has them) also you would have to check with the local building inspector to see if they are acceptable.

I was able to attach both a USB battery backup and/or external power, but had to modify the waterproof case to do it.Also, there is no wireless download of data, so you'll have to pull down the camera and swap SD cards every once in a while as well.I've also used the Dropcam. 

STATS - 40” (39.5” actual diagonal) 1080p FHD LED TV 1080p Resolution - Crystal clear picture, bringing out more lifelike color, texture and detail Roku Smart TV - wirelessly stream 500,000+ movies and TV episodes available across thousands of free or paid channels, conveniently presented through your own customizable home screen Free Mobile App - Can't find your remote?

A wireless system will still need to have the power to the cameras wired in, the resolution won't be as good, but it will still be plenty effective.In order to constantly monitor a system like this remotely, you will need, yes, good internet.
