I’m technically savvy, are there any DIY options out there that would provide entry and motion sensors with a siren and alerting on my phone without a monthly fee? Don’t necessarily need calling to law enforcement, just looking for alerting and a deterrent. I was looking at Simplisafe and liked the idea of their system with no contract, but they don’t seem to provide phone alerting without the contract. Thanks for any suggestions!

Obviously there are limitations on what you can do to a place you rent. Some things are the following:

1. Some form of security system meant for rental units and not a hardwired system.
2. Replacing or adding a new lock to the door. Preferably a quality one without easy bypasses and vulnerabilities. Note that in almost all cases you will have to provide a key to your apartment management for access for maintenance or emergencies.
3. Window/door security bars to make it more difficult to open these.
4. Blackout curtains to prevent people canvasing looking for valuables. Bonus they help for light and temperature control and save money on bills.
5. Metal door+upgraded frame? Is this viable for renting?

Thoughts? Anything I’m missing? Would you recommend one or more of these things?

I’d love recommendations for a good system that hasn’t had too many known issues.
