Compared to HDW2231-RZ and HDW5231R-ZE which both sport a metal housing throughout, this thing has a plastic outer encasing and base ring. Only the camera body ball itself is metal. The plastic construction housing also seems to be more prone to attract finger dirt during installation. The upside of this plastic construction is that there is no more set screw to install or lose. The whole body enclosure snaps into place and can be quick-released immediately with a push of a button. This is quite an advantage and I didn't find much fault in it. The downside is if this camera isn't mounted high up enough, someone could quick-release your camera and steal it! Video Quality: -On par with HDW2231R-ZS and HDW5231R-ZE Starlight family. In fact, I think they use the same sensor. Bidirectional talk: -This camera supports 2-way bidirectional talk just from using the Dahua iDMSS Plus app and is waterproof up to IP67. The audio coming out of the camera from 2-way talk is very good, much better than the pre-recorded files in my opinion. The audio received and played by your phone on the iDMSS Dahua app could be better and contains a lot of sharp echoing when activated initially. This goes away after 5 seconds. There is a Noise Filter mode which you can enable but that only drowns out the background noise (hissing), kind of like noise cancellation of Bose. It works acceptably okay, but don't expect Bose quality. The microphone and speaker volume can be independently adjusted from 0-100. But it cannot be adjusted in the app. Active Deterrence (visual): -This camera has a semi-programmable flashing LED or solid LED if the IVS is stripped. The duration can be changed from 5-30seconds. However, it can only be triggered by IVS, not motion detection. It would be easy for Dahua to change their firmware to allow the LED to be triggered by motion detection as well, but I do not know why they didn't do that. The LED light is not that powerful but not too weak. It is good for a small porch to light up the face of someone, but don't expect to use it in your yard and expect your camera to kick into color mode. Won't happen. Active Deterrence (audio): -It can play pre-recorded audio clips such as: Danger no climbing.wav You are under surveillance.wav Sidewalk only no vehicles.wav alarm.wav The alarm.wav is rather pretty loud. I would not use this personally since I live in a tight-knit PUD neighborhood. There is no way my neighbors would appreciate hearing this especially with false triggers. Another advantage: It allows you to upload any pre-recorded PCM wav files of your choosing. However, the format only supports PCM 8000Hz. I have tried using higher quality 24000 to 48000HZ file and it will not allow it. The problem with 8000Hz is that the sound quality is not that great. It sounds a bit robotic and tingy, but acceptable. You can have multiple IVS triggers defined and set to play different audio files and have different LED visual flashing or no flashing. People Counting/Heat Map It has people counting and heat map feature as well. But I have not tried to use this since this is only for front door, not a concert. Compatible with PFA200G Gang Box Adapter The camera is 100% direct-fit and bolts right up to a PFA200G gang box adapter. You can buy one from @EMPIRETECANDY : https://www.amazon.com/gp/product/B07RL64CK9/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 Why you should buy this camera: You don't want to pay Nest or Ring doorbells subscription for video recordings, but you also want to have bidrectional audio/video support. This is it. You want to have programmable audio deterrence and/or visual led light. You want Starlight quality camera. Why did I buy this camera: I don't own a video doorbell camera and I am holding out as long as I can. But there have been times where the delivery truck driver for either appliances, furniture, or whatever shows up and I am unable to speak to them to tell them to wait for me to come home. So after numerous encounters, I've decided to upgrade to this camera to serve this purpose. Active Deterrence in action with personally pre-programmed audio: Warning! F-BOMB foul language ALERT!
