Great product, easy to setup with the feit app, prerequisites include a powerful 12vdc power supply to support multiple cameras, a fuse block, 1 per camera, an appropriate size mini sd card, 128gig max...and keep in mind that these cameras probably have a 3.8 or 4mm lens, they are not wide angle, but perfect when placed properly. Remember the goal...to see the faces. Good wifi is a must, may have to add an extender or wap, but very reliable alarm event recording is best but sensitivity is high even when adjusted to low and after adjusting the zone, still sends frequent alarms because the wind is blowing a tree branch, ir the headlight of a passing car reflects off of something, no big issue, it is what it is, works solid and reliable in my application
