I strongly disagree with SIA's lobbying on this. There are plenty of alternatives to Hikvision and Dahua, even where cost is a consideration (Hanwha Wisenet X, Avigilon SL, Axis Companion, and others). It seems unrealistic that integrators doing a lot of business with the government, who would be banned from purchasing these products, would not be able to maintain a profitable business if they could not sell these systems at all. The likelihood that someone is doing substantial government business and substantial low-cost commodity business should be fairly low. Some integrators may need to pick one channel or the other, but I do not buy that they would be subject to "crippling" effects.
Additionally, if you believe these products represent a potential high risk of cyber security compromise, then this makes even more sense. Most integrators will have the equipment they sell and install setup in some kind of a lab, which may not be properly isolated from the rest of their network. If these devices represent a risk of remote attack, I would not want an integrator that does a lot of government-related business having their internal network open to an easy attack which could reveal compromising data about those government systems.
Finally, Hikvision, Dahua and Huawei have mostly brought this on themselves. Hikvision has an absolutely horrible cyber security record, and despite a lot of talk and hiring fashionably dressed security spokesmodels, has not shown true dedicated to making their devices truly secure. Dahua and Huawei have plenty of security knocks against them as well.
That Hikvision, Dahua, and Huawei are not choosing to address this by offering up the integrity of their products for inspection, and instead relying on money-driven organizations like SIA to campaign for them instead is very telling.
