Review on 2K&2-Way Audio&Floodlight Tonton Portable LCD Security Camera System: 7" IPS Touchscreen Monitor, 4CH NVR & 4 3MP Cameras W/ PIR Sensor + 32GB SD Card by Douglas Hall

Bought this to do double duty as baby monitor and security system. Had to contact tech support a couple times to figure out how to keep the sound from turning off since we need to hear the kid but finally got it mostly set. Video is great both for day and night. Only issue now, and it’s worrisome, is there is a lag of a minute or so. I can say goodnight, go downstairs to the base unit and see & hear myself talking. It’s not easy to find a system with two-way talk and they’re not cheap, but I may continue to look.and hope there isn’t an emergency where 30-60 seconds makes a difference in even hearing it happening
