Query: Q-See Wireless Door Intercom and Video

I have received two of this item and neither one of them worked. The directions are contradictory with labeling. As an example: instructions state to insert 6 AAA batteries when only AA batteries will fit. The plus and minus labels in the battery department are oppisite the stamped area in the compartment.Bottom line - I have not received a working unit, therefore, I can not testify as to the quality of one that works.
