To see how these analytics work in real-world scenes, we tested indoors and out, using multiple cameras and fields of view:

We have been unable to get Hikvision Tripwire to work reliably in any model of camera, with the exception of cameras connected to a Hikvision 77xx series NVR. It seems their analytics are more reliable when connected to an NVR. I will admit, this was with very limited testing, but it was a casual observation we have made over time.

I'd like to see a shootout.
"Worst Analytics"
Put Hikvision, Dahua, Hanwha, Bosch, Avigilon, Ganz and DW all side by side and see which one's have the most false alarms. I don't even care about actual alarms, just false alarms. That would be a good show.
Every time a rep comes in and tries to sell me on how their analytics are better than anyone else's, I ask for a free camera to test them before I even consider signing their NDA or signing up for their partner program. Most never call me again.
Here's my conclusion, analytics aren't great. Most of the time they're a marketing gimmick.
I made the decision about two years ago to switch to using Spectrum and haven't looked back. At the same time, our team decided to record 24/7 low res and high res on motion. Using the smart search function has been far more valuable to our customers than most analytics.
We just put in 40 cameras at a high-security building. One pointing right at the entrance (thanks IPVM camera calculator). I showed them the smart search and we looked through a day worth of video. ALL we saw were cars coming in and out of their driveway.
AI and Machine Learning is the future, I think analytics were a great failed experiment (for the most part...not all analytics totally suck). Now it's time to learn from the failure and move on.

John,
Smart Search is great but very limited for proactive measures. In all cases, preventing a crime or dangerous situation is better than reacting to it after it happens. This is where analytics come in as you can immediately notify staff on site and\or trigger lights, sirens, activate third-party text messaging services, or play prerecorded message for deterrence, you can automatically create and tag a bookmark to save time on viewing potentially hundreds of smart search events, you can trigger presets on PTZs or zoom lens cameras to get a much more detailed look at the event and the list can go on and on.
Even in your example, if you could only show events on cars that were a specific color, that could have reduced the amount of investigation time by 99% potentially. What if you were looking for a pedestrian walking through the area where only cars are supposed to go?
Any rep who promises the world with their analytics, or even uses analytics as a main selling point is a bad or lazy rep or they have a low-quality product in general (or they are tricked by their own marketing and have little real world experience).
A good rep will apply analytics as part of a solution to solve a problem and manage expectations of what the analytics will provide and advise you to add another 5 hours of labor to your install for thorough testing. (false alarm rate in varying conditions, correct camera positioning, activation scheduling, most efficient configuration, advice on policy or procedure to use analytics efficiently, what to do with the data, etc.) Or, they will tell you a physical barrier or device would work much better than a digital one.
A deep understanding of the analytic and having a VMS capable of automated actions based on that analytic event can win you projects against lower-cost competitors and can greatly increase the potential for ROI for your customer beyond just the operational efficiency of Smart Search.

I get what you are saying and this is a great support of my point. The application for that doorbell cam is the perfect situation for face detection analytic. The height it is mounted at, the distance faces will be from 2MP, integrated IR, they even configure the aspect ratio in 4:3.
Then you have reps who will just say, "Put this baby in your warehouse and you can tell humans from other forms of motion, then configure your VMS to send a text message when it happens" and the end user wonders why his forklift drivers 80 feet from the camera with strong backlighting from the open bay door shadow out their face aren't detected, but a shelf of gizmos 15 feet away with human faces on the marketing box sends a text at 3am.

Have you ever talked with someone from HV to see how to properly set VCA on their cameras?
In the first example (outside scene)you are setting it wrong...you just cannot pretend to cover all that area but should draw a corridor in the middle of the area instead
Plus HV is clear about false alarms if you cover bushes,branches,leaves etc...they should just be taken out of the smart area
Also is it my monitor that is gone or you have some color problems with the camera (i see purple everywhere) white balance?ir cut filter?if you have wrong chroma again you cannot pretend things to work perfectly
In my experience with correct position of the camera, correct lens choice and correct settings of the cameras i find it easier to have false negatives than false positives..
Plus i would expect to see a test of vca on thermal cameras since it's 2018...that's the real deal to be used with video analitics...we are using HV thermal with VCA to protect outside areas and get 98% reliability even in "wild areas "
Don't want to sound as an HV commercial but there are rules to follow when it comes to video analithics plus the company is pretty clear about limitations of some features at least HV Italy is and they are taking great care about costumers being teached how to properly set the cameras

We ran an outdoor test with the newest Axis AVMD and generally it was fantastic. But running against something picking up all motion (lights, trees, etc.) we found the AVMD missed 4 people walking across a parking lot. This was without the small size filter. Yes the other had a hundred events and the Axis was almost perfect, but picking up 95% of the events is a failure more so than picking up too many events.
That's a problem....you don't know what you miss. It is not reliable enough for our customers yet. We also tested SightHound and found the same problem...it missed 2 people at night at an entrance. Big deal to miss events. Easy in a doorway or controlled area, but not as much in difficult conditions.
