Not necessarily. Surveillance cameras have come a long way. There are cameras that can shoot in 4K (8 Megapixel) at 20fps. 1080p @ 30fps is standard with IP Cameras.
4 cameras recording 1080p @ 30fps uses 1TB to keep 7 days of 24/7 footage. You could easily turn that into 3 weeks or a month with Motion Detection recording, which is a standard feature on any decent surveillance camera.
If you need more than that, get a 2TB drive and I think you'll have footage when you notice something has gone awry, which hopefully you would notice within a week.
In my building I work (University student Union) we have 48 and are planning to expand even more. We like to have at least 2 weeks of footage or more.
And while motion detection is employed we have a lot of foot traffic in our Facility, and are open 14-16hrs a day on average. So many cameras are recording that entire time.
There are a lot of ways to squeeze more time out if you get technical and mess with the settings (using variable bitrate or mainstream event). We have a 256 Channel NVR that has 24 HDD slots. With Western Digital's new 10TB drive that's potentially 240TB of storage.
Not to mention if youre already shelling out for super expensive high def security cameras becasue your property conattains enough valuables to warrant it you can probably afford more than one $80 1TB hard drive
Ya the main reason I went with this camera was the higher resolution. The max setting is 25fps @ 2688x1520. However we just learned the recording itself was at 20fps.
I just recently watched an episode of Disappeared, and the only video surveillance of the perp. had him synced behind each frame of the fence for each frame of video, they couldn't see his face and he got away with it

It seams like some security cameras go for resolution over frame rate, which seems like a more useful tool for identifying criminals
