DIY security installations can be a good solution if the system is a simple camera or a couple of wireless sensors. Your biggest concern will be placing them in the right spots, at the correct angles and making sure all components of your system work as they should.
DIY can save you money by not having to pay a professional technician to install your system.
Good for temporary security solutions and wireless systems that do not require an integrated approach (i.e. you aren’t linking up many cameras and monitors).
