This is a great system and I would highly recommend it to anybody who is on a budget. Was a little finnicky to set up as I had an older router and a bad coax cable but once set up it was everything I had hoped for. This is a great purchase for people in apartments or for people who are renting any sort of facility and are forbidden from putting screws etc. in the walls. I love how you can pick and choose when to stop cameras from recording but still receive notifications for movement and sound. The only things I am yet to find (I just set it all up today) is how to transfer/delete the videos without having to remove the SD card from each camera individually and how to set it up on a schedule for certain days and times to record.
