Review on 📷 ZOSI 4-Pack 2.0MP 1080P 1920TVL HD-TVI CCTV Camera Kit: Day/Night Vision, Waterproof, Aluminum Housing, for 720P/1080N/1080P/5MP/4K HD-TVI AHD CVI Analog DVR Systems by Bob Larson

At first this system was great. The installation was very easy and the image quality day and night is acceptable for this price range. However, we had problems about two months after purchase and there is very little reliable troubleshooting information on the company's website. Our system refused to recognize the cameras and was unable to fix it following the few suggestions we could find. Numerous complete resets didn't help either. We eventually brought it back and replaced it with the Blink system. Bottom line, you get what you pay for, especially in terms of support should you have any problems. I really cannot recommend this system.
