This should be interesting to watch. I love watching this kind of thing play out. Always so much to learn.
On team Hikvision you have a massive market share with millions of cameras and dvrs. Most of the cameras I see day-to-day are Hikvision. Just last week I met a guy who hired me on the side to come help him out with his Hikvision NVR (the new one with the new UI) he couldn't get the cameras from the old recorder to work on the new recorder. My point is, this guy loved his Hikvision NVR. I know a lot of consumers who do, they're not paying attention to what Genetec is doing or what reports come out on IPVM. Not saying this is right or wrong it's just how it is. I've found that most consumers do not care about the level of security in their IoT products. As soon as they see the price tag of a higher quality product they often are willing to take the risk.
On team Genetec you have very capable video management software deployed inside a higher end market that is smaller than Hikvisions. People who use Genetec care about the security of their equipment and can afford more expensive cameras. Until the Chinese government isn't involved in Hikvision these clients will almost always side with Genetec.
Hikvision wanted to get into this high-end market, Genetec is making this very difficult. If other VMS's decided to play nice with Hikvision and promote their product than Hikvision will win this in the long run.
If other VMS follow suit and start shutting out Hikvision than Hikvision is bound to lose in the US market regardless of what consumers think. Selling 4 camera systems isn't going to cut it in the long run or make the cost of operating in the US market worth it.
What should they do? In a perfect world, we would see them work together. We would see the hostility between the US and China go away and we could all work together to make a safer more secure world. The reality is that won't happen for a long time if ever. In the business world, it's time for them to duke it out.
