Big cities are fun and engaging places to live and offer many fun things to do all of time. But they also have very high population densities, which means that with all of the good people and fun things to do, there are also a lot of bad people lurking in the shadows, so it is very important to pay attention and be safe. This is especially crucial to take into account when thinking about your apartment building.

Here are some safety tips that can help you keep your apartment safe. They are simple, effective and can make a large difference in keeping you safe while you are at home.

* Always make sure that the main entry door of your apartment building shuts completely behind you when you enter your building. This is one of the most common ways that common thieves get into apartment buildings to rob the people who live there.

* Always lock the front door of your apartment when you are home and when you are not. It is obvious why you would lock your front door when you are not at home, but locking your door when you are home makes sure that if for any reason a stranger gets into the building, you will at least have your personal door locked and they will not be able to get in to your apartment. There are a lot of people who do not take the time to make sure the building entry door closes all the way either because they are in a hurry or because their mind is just in another place. So, do what you can to take care of yourself. Lock your door.

* Never leave any type of note on your door or on your mailbox downstairs near the apartment entry saying that you have gone out of town for any reason. These types of notes are an invitation to a robber because he knows directly that you are not there, so he can break into your apartment and spend as much time in there as he wants. Instead, give a key to a trusted friend to your apartment and your mailbox and let your doorman know when you leave, and they can pass by from time to make sure that your place is in good shape and tend to your mail.

* Install a peephole in your door if you do not already have one. This can help you avoid letting any unwanted visitors into your apartment because you will be able to see who is there and if you want to let them into your apartment before you have already opened the door and it is too late.

* Always go down to the entry door of your apartment building to let your guests in if you do not have a security camera that makes it possible to see everyone at the door in your apartment. This is very important because many thieves take advantage of someone waiting to be let into an apartment building and they hold them hostage quietly so when the guest is buzzed in, they come in to rob people.

* And finally, put a home security system in your apartment if you do not already have one. Any type of home alarm or home security system is the best way to keep your apartment safe during the day and night. They can be costly but home security that allows you to be comfortable in your apartment and sleep easily really has no tangible price.
