We purchased this for our first baby! Has awesome clarity both day and night. No issues ever with the connection. The only reason I don't give it 5 stars is that summer only has certain compatible cameras. If you want to expand your system or replace something down the road you are out of luck. I finally found a compatible camera online and paid a fortune rather than replace the system but dropped and broke my monitor. Not wanting to put more money into this system we went with a different system.
Overall loved this system but recommend buying the cameras you will need for future children at the time you buy the system. We only have 2 years between kids and it was obsolete. Not even shown on their website
