Actually, the viewable range was at least as good at night as it was during the day. I could see faces very clearly up to about 25 feet. With the Defender SP301 C, the night vision is acceptable, but very basic. The camera has 12 Infrared LED lights, which allow you to see fairly clear images even in the dark. The downside is that these images are only viewable within about 15 feet. There are many, many other cameras with a much further range. On the other hand, how far do you really need to see?How would you determine someone is a threat until they get close to the home or business anyway?Is a burglar going to come strolling up with a crowbar or gun already brandished?This is not likely. Therefore, I personally take claims of a long range or field of vision with a grain of salt. So, 15 feet would probably be acceptable. As with most models, you can display the data directly on your computer. I find it quite fascinating to spend time every day just looking through at my different cameras in order to see everything that is going on within my home.
