This is an incredible home security camera set up! I have had different security camera set ups for over 20 years and this is by far the best system I have owned to date!The cameras are the heart of the system incorporating separate fixed and PTZ (pan, tilt, zoom) cameras in each housing that work in tandem to identify movement and track it. The separate camera units can be linked so movement on 1 signals the next to move to track the movement, this allows movement to be followed around the property. You get 4 of these bullet PTZ camera units accounting for 8 different camera feeds. I walk out my front door and instantly I have a stalker, they are super cool! The video produced is super clear and items can be easily identified, the reason we have cameras in the first place!System set up is easy. Plug the NVR into the router, load the app, create a log in and continue with the set up process. The cameras connect themselves when plugged in. Running the wires is the hardest part of the whole process and could or should be left to a professional if access is limited. I only have 2 cameras connected at the moment as it's too hot to be in the attic until it gets cooler. 4 - 59' ethernet cables are provided for power and data for the cameras, no separate power supply for the individual cameras, power comes directly from the NVR. The cables have weather tight fittings to keep the moisture out and protect the connections. From my research it appears Cat6 cable can be used for longer runs and the weather seal can be installed over the rj45 connectors protecting the connection.The app is easy to navigate and to make changes. Individual users can have different settings for notification tone, time between alerts and various other items settings. Items like camera angle can be adjusted through the app for the PTZ cameras, detection zones can be set to your needs and sensitivity can be adjusted. I have mine set up to give me a notification sound and a pop up on my lock screen that shows what camera and if it was a car, pet, person or someone the system recognizes by name. Yes the system has face recognition and it allows you to assign a title to the person.I was unsure when I ordered the system exactly what I was looking at I had never heard of Eufy before. The cameras are phenomenal! The whole system works together flawlessly to follow movement on my property and allow easy recall of the events. It really gives me peace of mind when I'm at home or away helping me keep my family safe! No area of my house will have a blind spot now! I had issues with blind corners even with 8 individual cameras as they were all fixed. Plus additional cameras can be added with the Bullet PTZ cameras currently listed at $279.99, or single PTZ or bullet cameras also being available at a lower cost.This camera set up will impress! I fully recommend the system and at the current list price of $1299.99 it is a bargain for the equipment you receive! I was skeptical of the initial price wondering if it was truly worth it, seeing truly is believing!
