A high level of mobility implies some sort of rechargeable battery source sized based on expected run time.

You should inspect the interior at a minimum of twice over year and check the batteries in the smoke detectors and look for damage or broken items that need repair.

Battery production is supposed to begin in 2017.The flip side, if Tesla fails to finish the construction.

I don't like plug in or battery powered because the tenants will remove them.  

I have a long time alarm contractor hardwire them (lots of batteries are a pain).  

Downside is that if you're using it outside with it's water-proof case, it doesn't get external power (just the battery pack), which will only last a few hours.

You should also test all batteries in smoke detectors ahead of the inspection and be on the lookout for any lights that are out particularly in hallways or stairways.Many of these are things that the tenants should have told you about, but you don't want to find out the hard way when Section 8 fails you for something like that.

Assuming there is zero way to get other power to those fixtures (including paying an electrician a few hundred $’s so it’s right for this and following tenants.) and you can’t find a decent battery operated version.
