. For now, I am thinking of maybe just installing a temporary system like t=

The resolution is pretty poor in multicamera view and you're only getting 1=

Don't believe the 30 foot night view spec, they're not usually as good as t=

If you're trying to see a large area, you're not gong to get a very good vi=

work better, but will still be kind of blurry. At night I'm guessing it'll =
be all but worthless for ID purposes, unless they get up very close to the =
camera. I would investigate further on how you go about playing back the vi=
deo. But for the price ..... at least it's "something".
