I already had 2 smart cameras at 1080p resolution that were fine during the day but not very good with low light but wanted something better, with more features and 4k resolution. I first looked at upgrading to 2, better, smart cameras that seemed to have everything i was looking for. I then stumbled across USE-IP and realised, for the same price, i could get a 2 camera system from Hikvision that is a lot better than i was already looking at, especially in low light. I was new to IP cameras when i started looking but with online support from the staff themselves (before and after i purchased) and a great forum that had all the info i was looking for, i managed the installation and setup myself. USE-IP will definitely be my first port of call next time.
