I am looking for a good home security system, but I don't have a lot of money to spend.

You may want to consider getting a DIY home security system instead. These systems can be set up with minimal cost and are often more reliable than professionally installed systems. They typically use sensors such as door/window contacts, motion detectors, glass break detectors, and other devices that alert you when they detect something unusual happening in your home. There are also some DIY systems that offer remote access features so you can check on your home from anywhere.
