I am not sure. It might also get sold out, as there is no card next to it. The "*" on price tag means the stock is in limited quantity.
In general I have been disappointed with the newer Lorex cameras using smaller sensors.
As such I think the Lorex kits are less useful if you need low light performance.
The cameras in this kit look like newer models which I do not know much about about, so I would have to check of they are even dahua oem.
If the kit is a dahua oem ip poe kit .. then you could typically augment it with a few better dahua oem cameras.
One nice thing that I like(d) about costco is the return policy .. IMHO the best around for security cameras .. so you could typically take a kit home and bench test before climbing any ladders to see of they work for your setup.
Feel free to post more specs on this kit if you find more info on it.
