Does it make sense to install security as a landlord?

[Rob Strickland]

We are getting ready to rent out our first property which is a 3 unit and we're thinking it would be a good idea for the property to have a security system in place.  It's right on the edge of the very desirable location of the neighborhood and a portion of the neighborhood that hasn't completely transitioned yet.  Does is makes sense for use as a landlord to have a security system installed to monitor each of the 3 units or is this something we should leave up to the tenants?
