CCTV Recommendation

[Biogentic]

Hi, anyone has recommendation of CCTV system? Required 6 CCTV Camera with DVR. I looked at Panasonic but the specs are not as good as those "unheard" brand yet it cost so much higher. I went to Jia Ying and saw they are selling Webgate and Panasonic brand CCTV. The webgate look impressive but I am unsure if it is reliable, any feedback or I should go for the Panasonic CCTV which cost a lot higher. One thing I notice, the Panasonic CCTV & DVR they are selling are discontinued model. Is there any cause of concern?
