Knowing when someone is on your property is always important. You have a duty to protect yourself, your family, your property and your prepping supplies, so doing anything possible to enable that is the number one goal you should have in mind.
For that reason, having a series of advanced warning systems on your property is an excellent idea so you can be alert and prepared should somebody make the mistake of coming uninvited.
Unfortunately, most alarm systems are very expensive and will be rendered useless should the power go out.
So what should you do? Improvise!
Follow the prepper mantra of looking at what is available to you and turning it into something that's useful for you. Making an advanced warning system out of a dollar store siren? Easy.
