Arlo is the first security camera I have ever used. It exceeded my expectation. It was easy to activate using home Wi-Fi and get 3 cameras working. I have been using the system for 4 months and it detected every human and pet movement within the detection area. I moved the cameras to different spots to decide the best spot that met my needs. I did not need any technical help or wiring to get all of them working well as exterior cameras. I recommend Arlo for those looking for a simple to operate but effective security system. My front door camera needed charging after 3 months.
