Bearing in mind I do not have a cellular phone plan this was ideal.

(This is a hysterical laugh...)Here is what I've been searching for the last half hour:IP Security Camera with or without tilt controlNight visionMotion sensorBattery operated/solar poweredOutdoor/indoorBuilt-in internet / mobile connection (ie records video to cloud without internet present)Affordable (<~$100)I'm not sure if I'm searching the right keywords, but here are the items I've found which still don't do fall 100% under the criteria I listed above:http://www.amazon.com/TENVIS-JPT3815W-Surveillance...http://pro-vigil.com/live-security-monitoring/http://www.amazon.com/Foscam-FI8918W-Wireless-Netw...http://www.amazon.com/Covert-Special-Ops-Cellular-...The last one is a trail cam which takes pics and sends them through MMS!

:)On a serious note, I personally picked the option of getting the cellular data plan so that I do NOT have to be within WIFI range to gain access.

Foolishly installed a smart oil gauge to track oil usage and predict spikes due to windows open or other tenant bad behavior... before realizing I don't control their WiFi and don't have cell coverage in basement to link to a cellular hotspot (oops). 

Plus, they have their own cellular transmitter, so no wi-fi is needed.  

We manufacture and have the patent on the only Smart smoke detector that is completely self contained and monitored 24/7 through cellular networks.

Anyone have leads on a smart door locks that support cellular service or something that lets us set the code remotely?

For our own, I greatly prefer cellular shades.  

Put a Wi-Fi or cellular lockbox on the unit (like realtors have) that can be managed remotely.
