Hello, Yes, these cameras would be compatible with the LH0504 system, however the model you have listed is a 4ch DVR with 4 cameras so does not have room for expansion. Thanks, Lorex
Hello, These cameras are intended to add to a DVR system (960H analog up to 900TVL cameras). Please contact Lorex customer service directly for assistance with compatibility on the model that you currently own. Thanks, Lorex
