1. If you are a Hikvision employed sales rep do these sales severely hamper your commission? Imagine that one day a deal is about to closed for $200k of your product and the sale hits right as the customer is about to place an order.
Sales do impact commissions in the sense that you are now earning a commission on a lower invoice amount. I have also heard from Hikvision employees/ex-employees and integrators that discounts on Hikvision equipment are not that hard to get right now in general. So, that $200K order has a high probability that it was going to be $250K originally, and the customer was already given a discount to incent the order, making the sale announcement have no real impact.
Front-line employees at distributors I have spoken with in the past say they "love" these sales, it generates more calls/sales, and gives them more opportunities to upsell other items (those cheap cameras and recorders likely need cables, switches, workstations, monitors, etc.)
I have not heard of commissions for Hikvision employees or distributors being limited or cut just because of a sale. I know you did not ask that specifically, but it is something done from time to time by companies when products are deeply discounted.
