Query: Lorex Cameras Are Junk

I purchased a L15LD420 surveillence package in October. Within 7 months the four cameras (CVC6993R) had night vision failures. The IRs would not switch on because of a mechanical auto IR filter cut failure. This is an ongoing problem with Lorex cameras (well documented in reviews of their cameras). You would be far better off with another brand if you want something reliable, which is an absolute for a security system.
