bfldworker 0 Posted October 20, 2017 I as a rule don't install or upgrade CCTV systems. That said I got asked to upgrade some cameras for a older couple who lives next door. They have limited funds and want to upgrade the 8 cameras they have. They have a QSEE QS4816 DVR and have 8 600TVL cameras, they have night vision and the cameras cover the entire property. However being they are 600tvl they don't have the best resolution. My question is this, or should I say there question is, can they upgrade the cameras to something better then 600tvl (700-1000) that will work with they system and will give them better resolution but also a low, low price.? As I said I don't install for people. The only CCTV installs I have done are for my in-laws and my own. Suggestions please Share this post Link to post Share on other sites
