It's possible to use outdoor security cameras indoors because the fundamentals of protecting your home and your yard are the same. However, due to the durable, weather-resistant design, size, weight, and increased field of view and range, outdoor models typically cost more than indoor cameras. If you're only planning to use a camera indoors, you may find yourself paying for features on an outdoor camera that you don't want or need. “Many outdoor security cameras need to be wired into your home’s junction box and, as such, are specifically designed for outdoor use,” says Roth. In this instance, installation may require running cables outside to bring them back indoors, adding unnecessary complications and costs. If you want a multi-purpose camera or a network of the same cameras inside and out, opt for models with explicit indoor/outdoor compatibility (and labeling).
