how long is the run ? are you using solid core copper conductor and braid copper shield? As someone mention swap camera with another one , then if the run you are have problem on is still bad with other camera , i would consider if you are using cca type of wire, video signal drops after a certain length.

i had similar problem , not with resolution , but menu . could not get it to change certain settings on menu , tried with DVR and on camera it self . Took camera back to vendor , he reset some setting on camera all good.

I got a big job coming up , do a shopping center with 16 ch nvr some motorized cameras 1 5-50 mm, 2 2-12 mm, the others 4 mm domes using 2 mp cameras , using nvr amcrest dvr so I can record and playback 1080p . I running coaxial areial wire bc most wire be exposed to sunlight. Cameras I plan on purchasing are from a new company GNS , the claim their cameras are HIK VIS but without the name brand. Has anyone bought from them before. My concern are these cameras really from HIK VIS or not. Also in installing systems for customers , sometimes the diy buys his equipment and I install. I get complaints about logging into Swann, Lorex, Owl,andyou others . I go check it out and system is working I always hardwire Ethernet cable as close as possible to dvr/ nvr.it seems those systems servers bottle neck and causes problems . When I do Amcrest dvr/ nvr I never get those complaints . This why I sticking to Amcrest NVR recorder because it always been reliable. Like to hear your thoughts as to what system you would recommend . As always customer wants as low price he an getaway with . But he wants decent quality.
