UL-Tech 8-Channel Wireless Security Camera System

Software full of bugs – I purchased two of these UL-Tech wired 8 chanel cctv systems from ebay at different times, both have different software versions, both systems are full of bugs, things that don't work , day light savings settings won't go past the year 2000, movement alarms won't indicate separately from normal alarms making the system extremely hard to navigate and find any recorded files required, many other bugs and things that don't work that make the system un user friendly, manufacturer warranty and customer service is impossible/ebay sellers also extremely difficult to deal with, keep going to and fro the manufacturer and never sorting out the issues asking for photos of things that don't work, mmm how can you send a photo of something that is not happening ? Camera quality and recordings are fair to responsible for a low cost system but in my opinion all the bugs prity much make the system useless unless you just want it to monitor and watch without recording events
