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 Doug Booth

Battery life is 1 to 6 months, actual battery charge is 2 to 4 days. The description says "full charge". I charged the batteries for over 48 hours after the battery indicator turned blue. The battery still didn't last more than 3 days. This camera is located in a very restricted traffic area. According to the description, you can count on a battery life of several months. The second big problem is the total lack of documentation. All attempts to find more detailed product documentation have been unsuccessful. I could find documentation for other systems but not this one. In order to learn how to use the dash cam software, you have to click on each option to find out. My DVR records some days and not others. Can't find any documentation to understand this. This product is not worth the hassle.
