@Lucas Vanroboys  We us a speco blue system with high quality cameras.

The first step would be what Ricardo said, plus a lease revision with fines, and a clause reserving the right to install cameras if needed. 

This is a laarge issue in my market even without dumpsters, the suburbanites like to drive down to the city and dump **** in our alleys and use our trash cans, used to be a bigger issue when we had large communal trash bins in the alley.The only thing i've seen really work is putting up a camera and a sign and say if you put unauthorized trash here, we are gonna fine the bejeasus outa you...and that's about all I've seen work. keypad and enclosure is a great idea as long as noone leaves it open, I'd still do the camera even with the enclosure.

One thing we've done and recommend (but few owners want to pay for) is to install cameras to monitor common areas.Inevitably, a tenant or two often abuse their common area privileges by leaving trash, shoes, plants, etc. in common areas and it's nice to know who to hold accountable.Regarding building checkups, it's great if cleaning & lawn help can be trained and motivated to alert the owner/PMC on issues.

Made some decent money acting in commercials and doing professional theatre for a little.Filmed my school's football team and edited a hype video... worked my way up to getting paid to make videos for various teams and events.Tried to start a clothing brand, got a few sales, not proud to say I lost passion, focus and gave up.Started a YT channel, grew to 1,000+ subscribers, kids at school found it and I slowly stopped posting.Volunteered at a local church, started as a camera operator, showed up consistently, learned a ton and eventually worked my way up to working as director of the broadcast team for a couple of services. 

Line up at least two options for each role before you need them.Smart tech: Invest in a smart lock you can reset remotely, and cameras at entrances.

I hope you reported it to the police, if not, you should file a police report and also install cameras because there's an influx of squatter's taking over people's properties recently. 

@Rebecca Cho we like Lockly, which has a version with built-in camera - so you know who's coming and going.WARNING: smartlocks require wi-fi connection, so how will you provide that and who will pay?

If youre able, probably wouldnt hurt to put up a camera outside to see if someone is hooking up to an outside spigot or running some kind of water-intensive business out of one of the units. 

I see this as a non issue for me because I've never had someone not be able to get in.I proactively check via camera to make sure they got in.
