I like to buy the ones that are wireless (easier for self install) and do not have a subscription plan for video recording on the cloud.2) consider placing decibel readers within the house to detect loud noises (parties) past quiet hours.3) depending on the property or your portfolio, might be worth looking into direct bookings marketing

I want to set up wireless internet for them, but was wondering about liability in terms of what they end up doing online.

in order for your tenants to have cable or internet there has to be a way for them to bring that to every room, wireless is not always the answer.That said, you could always put in a clause that states that:  a tenant, visitor or any contractor shall not cause damage to any part of a structure by drilling, cutting or removing by any means possible any part of the structure of the property without written consent from the owner, or property manager.

I use a Schlage keypad, not bluetooth/wireless to avoid complication.

However Ubiquiti's management apps are more modern and easier to use for yourself and your staff.For development projects, I have been using wireless cameras (Arlo) in addition to an LTE modem.

They just have a unique product offering.Arlo wireless cameras may be a good option too on a smaller building like that.

Id advise them maybe, but also you can put up a game cam or a 5G wireless camera from amazon.

I want to install a wireless doorbell for each unit.

If it was a smart meter and you could get a wireless reading, you could theoretically just cut a small opening in a wall, install the meters at points downstream where only one apartment is getting the water, and then patch the wall and collect the monthly usage.

Hi Rosie, I’ve used wireless trail cameras on my properties for security purposes, with good results.They immediately send you text or email photos when triggered.
