Review - Dahua Wizmind IPC-HFW71242H-Z All Thanks to Andy (@EMPIRETECANDY) we have a new beast of an AI cam to test in exchange for a fair and honest review. This camera supports ANPR, Video Metadata along with regular Object Filtering (within Deep IVS), Face Detection (No Face Recognition Model in 12MP yet), People Counting AND People Queuing. For completeness, No SMD on this one. It also features the model specific mount which allows for audio via 3.5mm jack. So what is this new beast, well its a 12MP 1/1.7” 71242H and guess what, it brings back 4x3 aspect ratio :) On top of this it supports a mammoth 5 streams (with actual usable sub-stream settings, more below) in parallel.

This is a real nice addition to this cam. There are many times I’ve come across a need to access a sub-stream that I want high res and frame rate from to feed to a secondary application but have been hampered by a particular cameras abilities. This camera removes a number of those obstacles with a whole slew of sub stream options: Main stream: 4000 × 3000 @1-25/30 fps* Sub stream 1: 704 × 576@1-25fps, 704 × 480@1-30fps Sub stream 2: 1920 × 1080 @1-25/30 fps Sub stream 3: 1920 × 1080 @1-25/30 fps Sub stream 4: 704 × 576 @1-25 fps; 704 × 480 @1-30 fps * Main stream also support 0/90/180/270 rotation IF you choose 1080p res or below This means you can have your main stream to your NVR for example while pushing a 1920 x 1080 30fps (should you wish) to OpenALPR a home automation platform etc etc. Main stream has selectable bit rates to 16,384k and customizable to 17,664. Even Sub stream 2 & 3 you can even support up to 17k streams from each. VERY COOL ! Other Features This Cam Offers - AI IVS Face Detection People Counting / People Queuing Video Structuralization / Metadata ANPR (YES, like its former Ultra AI brothers & sisters this cam supports ANPR too) Initial Notes Important to remember these 7xxx series (formerly Ultra AI) have their own mount/junction box and you cannot use anything other than these for the bullet cam variants. Throw out your old SD card as this cam will chew it up and spit out frames due to the size of the overall image and write speed required. Therefore if you do use an SD card in your cam (like I do in most except for special projects or dark sites) then now is the time to upgrade.
