How many times have you seen bank robbery footage or other security cameras with really high quality footage? The quality of the video is typical of any security camera, the only argument you might have about the video is there is no other angles however it's certainly possible they exist but were never released. The other thing is the Pentagon is a massive facility and the crash didn't exactly happen in an area with a lot of traffic.
Security cameras are typically low quality to save space and that even applies to older tape models. With the older VHS tape models they might record 4 to 6 camera angles per frame, VHS has a very low resolution to start with. Unless the subject is really close you wouldn't get some really good facial features. A standard video runs at 30FPS, what they might do is turn that down to maybe 1 frame per second, or even lower. They might also use SLP mode which even reduces the quality more. If you're using 1 fps in SLP mode your 2 hour VHS tape can now hold 180 hours of video from 4 different angles.
The same thing apples to digital video. High quality video takes up a lot of space. As you lower the resolution, frame rate and quality of the video you can greatly reduce the amount of storage space required to store video which would be very important if you're in place like the Pentagon which probably has thousands of cameras.
The cameras themselves are going to be low quality and usually purposely built for the task, there's no sense using high quality cam unless it's one where a live feed is being monitored because your just going to reduce the quality for storage.
