You get the email - burglar or smoke. Immediately look at the cameras via you laptop black berry etc. You or the closest party is rushing to get to the grow to fix any problems.
I would consider smoke detectors, you could set it up so it kills power to the lights and other things and sends an email to all involved parties.
Same thing with a burglar alarm you would want to set it up so it was very unlikely to false, simple door and window contacts. You could set up the Burglar alarm to kill the lights too. This would send an email to you and your key associates. What to do if your getting robbed. Now you can't call police. You could put some sprinklers in there and remotely turn them on to cause them to get very wet. At any rate you must do something. You may need to be creative.
For a big grow internet and a UPS to keep your remote monitoring powered is a must.
A couple IR digital cameras H.264 and DVR to keep people honest.
http://www.onssi.com/ This is good software for your DVR. The reson is it supports alot of different cameras so your not locked into one brand.

Keep the DVR off site, could be used as evidence against you. Only a few cams not to bog down internet.
You can have cameras that can operate in total darkness like Arecont Vision AV3135
You can use IR flood lights to light the room in total darkness. These can also act as a burglar alarm and send an email if there is movement in a particular spot.
You can easily remote monitor your grow.
Guiest makes an inexpensive device that can do this
You can monitor temperature, air flow, humidity. It can send an email if any of these things get out of wack.

My thoughts on all this is to keep police and fire away from your grow.
which brings me to fire sprinklers. If you took out the risk of getting busted, growing was 100% legal this would be a must. You do not want things to get so bad that one of these goes off. The risk is water running out the door will attract attention the wrong kind. However you are in a pinch if a fire sprinkler goes off the fire dept is likely already on the way. This could be ok if it could not attract attention if it went off.
This can be remotely monitored via a flow switch that indicates a fire sprinkler activation, this would also be tied in to kill power.
This stuff all on a good UPS with good internet hookup.
You could do a wireless point to point link so there is no internet bill at that address.

Smoke with power kill
Burglar alarm
A couple good IR cams and offsite DVR
Remote monitor temp, air flow and humidity.
You probably already know this but I would get one of those good automatic bud trimmers the fewer people involved the better.
All my thoughts are about security.
If you were a bank and someone robbed you every cop in town would jump on it. There would be no risk to you.
Here in OG land some co opts have been robbed, some times employees are injured even shot by the robbers. They are victims of crime. But it seems that if the police are brought in often the place is shut down and the police fuck the co-opt over. Your running a business that has a very valuable commodity and it is well known the police will not protect.
All security falls on you. If you fuck up you could loose everything.
I would consider Oaksterdam U or something like it.
Have a relationship with an attorney that is an expert in medical marijuana law.
