Merchant, ZXHIN, does not provide after sales support. ZXHIN customer service would not tell me the maximum size Hard drive or micro SD card that the NVR and cameras would accept. They said, “We do not provide after sales support.” The app for remote viewing does not call or email back with a code, which means no remote viewing. The documentation provided with item, does not provide any storage info that is needed. I am now wondering if the specs. shown are correct. Sadly disillusioned.
