If there are problems with the apartment complex you own, you can keep an eye on things by installing a night vision camera in your parking lot.  You can also place one on the entrances of the apartments themselves to see what kind of traffic is going to them at night.  This way, you know what is going on in your building at all times.

Even if an apartment complex owner lives on the property, it can be difficult to keep track of everything that goes on.  Drug dealers could be living on your property and may not even know it.  Perhaps you retire earlier than some of the younger tenants and this is why you need more security.

Drug dealers typically have a lot of traffic coming in and out of their apartments.  This is how they make money.  While not every popular tenant may be selling drugs, it can be worth checking into.  Having a drug dealer on the premises is not going to bring in the type of tenants that you want.

They can also run off the good tenants that you already have.  It is also not a good thing for a family community.  By keeping an eye on who is coming in and out of your apartment complex, you are going to have a good idea of who is doing what.  Do not wait until there have been complaints to take action.

Since you cannot be around twenty four hours a day, seven days a week, install a night vision camera to be your eyes at night.  This is going to allow you to see what is going on and you can hold this information if there is ever a legal issue.  Protect your property from possible criminal activity by knowing who is coming on your property at all times.
