I use these:LEPOWER LED Security Lights Motion Sensor Light Outdoor, 38W 4200LM Light, 5500K, IP65 Waterproof, 3 Head Detected Flood for Garage, Yard, Porch (White) - Amazon.comWhen flipping out of state I go Simpli Safe.When it comes to local flips I have a home security contracting company that has their own alarm system and app that I really like so I use them but they are local to Cleveland. 

You can use WIFI or Cellular for a security alarm system.

Yes, this whole situation is alarming and I suspect it will get much worse before it ever gets better (if ever).

We make sure that our properties are on an agent lockbox and are alarmed.

There's no "prongs" lol.More than likely smoke alarms will have to be hardwired on a dedicated circuit with an interlocking wire.When the panel is upgraded a main building ground will be required under article 250 of NEC.

Now, I haven't had to do it yet as none of my current tenants have reported "non issues", and if someone reports something that turns out to be a false alarm, I wouldn't even charge them, as long as it was done in good faith. 

for certain its just like any business under capitalized business fail at an alarming rate.

None of our earlier models had any of these features.Probably won't get our damages back, but still feel happy adding to the thief's legal issues.Our locations stay really clean now.

Factors such as age, fire protection of the location, alarms, construction, proximity to a coast, etc. can impact the rates.  

Pregnancy complications are very scary and stressful, but I don’t think her response was overly severe, explaining what they’ve put up with and their alarm that it seems you’re going to be difficult.
