We have been dealing GKB for 5 Years their Cameras were superb at times but now they have revised their product line and reduced their prices to meet chinese competitors, i have checked their 1/4" cameras and they are crap but not sure about 1/3" and higher end. Meanwhile they had complete range of Fixed Cameras but it has been reduced to 7-8 Models.
Regarding DVRs and Speed Domes, GKB was worst in innovation and stability in both of these products. They used to revise their DVR models continuosly, but their current H.264 DVRs are relatively sounds good let's hope it will run smoothly.
Sunell also seems a good product, I have contacted Sunell but they are very arrogant I have been asking their represantative for prices in several mails but he is continuosly sending me other stuff.
