Hikvision didn't have much at ISC West that was new other than what I already posted. Those prices are lower, but could be a new reseller trying to disrupt the other resellers, just competition. What happens is they buy from Hikvision with minimum order quantities, end up with 300 and panic and dump them at lower prices. To give you an idea, I could have gotten those prices in the U.S. a year ago for Hik OEM bullets and it appears that some of the Ali sellers are going that route or if you noticed, some are blocking sales to the U.S. because they are all in Chinese (see my hack to fix this). I would not say they are cheaper today than a year ago, certainly not the U.S. models other than the sale at ADI Global that ends in 2 weeks.
