Dahua has released the IPC-HFW1831C-PIR an 8mp cam with built in PIR, mic/speaker and white light. This same camera is already sold under the lorex brand - lnb8105x and discussed in other threads. Unlike the 1831/2831 large 8k bullets that use a large 1/1.8 sensor good for low light, this uses the 1/2.5 sensor. Note they are only available in 2.8mm according to the spec sheet. https://www.dahuasecurity.com/products/productDetail/26977 EDIT: to clarify there is nothing in the specs about a speaker. The lorex version does have a speaker and there the dahua is almost certain to have one as well.
