Joke of the work of a friend of sales in Idis:
-Describe the brand in a nutshell.
-Large design brand.
-Yes, by the way #1 in Korea
-I hope not in North
Of course HJK.
With idis may be interested to contact if you have a project and want to monetize using its low prevalence. And HJK can be compared with Dachau.
I'll put my 5 cents :
if you want good and not too expensive, and normal stable firmware ( in the case of stocks, then their normal regular fix), normal support and STS ( believe me, if it's not a single object on the "done, dumped and changed your number", it is very important factors!) - Hikvision (and its sub-brand - HiWatch), Dahua, RVi ( but have to look on the old platform from Dahua!).
A little cheaper, more stocks, but you can also watch Falcon Eye ( this is a Dahua the current with a different label). There are STS in Moscow normally respond and mend regi and camera ( tested personally) .
The rest ( I do not take into account Bosch ( Oh, it also Daha, current Label and extra 0 in the price tag), Axis and other Big brands) - as a rule, since China with a strange firmware bugs and other "pleasures", including compatibility with each other. In the case of malfunction - throwing, in the case of a software glitch - go to Uncle Liao at Mitino or where they took the camera\reg.
So is your business. But give advice based on their experience of error and trial and error of thousands of installers, designers and system administrators of our vast - from Sakhalin to Kaliningrad ( worked in a support 4+ years) .
