Fenderman is right, return that SV3C and get a decent camera. Look in the
Cliff Notes in the
Wiki at the top of this page. The difference between SV3C and a decent camera will amaze you. Trust me, I have two SV3Cs that I've replaced with Dahua and their performance is well worth the, relatively, minor price difference. Also, try to use turret style cameras rather than bullets. Less problems with bugs and spiders. outside use of course.
