Anyone install cameras in common area in apt buildings?

[Eric S.]

Looking for experiences in installing camera systems in common areas in apt buildings. I have 3 storie apt building and thinking about installing cameras in the common hallways and one near the front entrance. Anyone share any feedback good or bad. Any brands they would recommend. The area is relatively good area and has good tenants for the most part, but recently a tenant left a very rude note on another tenant's door about being too loud. I feel it would naturally deter any bad behavior and if something was to happen concrete evidence to show the tenant and if worse the court's something happening. Also, depending on the person may provide additional security and comfort knowing that the building is being monitored. Thoughts?
