Acusense, Deep in View, TurboX

In the last couple of years CCTV has advanced via the use of the mobile apps to provide end-users with a means to immediately check on their property once a notification is received through the app. This appears to be a very popular feature, but having CCTV cameras set to notify of every possible movement, whether it's from a leaf, a shadow or the postman can become a nuisance meaning that the notifications become ignored or turned off. False alarm filtering has always been an important feature for central monitoring stations and often commercial set-ups will include addtional equipment such as PIR sensors to rule out false alarms, but now there are some new products from Hikvision which allow for built in false alarm filtering without the need for additional items.

Recently we have been having a lot of enquiries about some of the new Hikvision models which can aid in notifcations and words that keep cropping up in conversation are: Acusense, Deep In View, Turbo X.

In this blog I am going to try to explain a little bit about each of these terms and outline some products which fall into each category.

Deep In view cameras are designed with a specific feature set for a particular job. This could be an ANPR camera, People Counting camera, Facial Recognition camera, Heat mapping camera, Perimeter protection etc. These cameras can be added to a standard recorder for basic recording, but you may find that you need a specific recorder to perform querying of the advanced analytics.

Example Product: DS-2CD7A26G0/P-IZS

Acusense cameras: These can be thought of as cameras with analytics between Deep-in-view and standard IP cameras. They work in the same way as standard IP cameras but with some additional features, essentially they do away with Standard Motion detection and move to Human Form and vehicle form working alongside intrusion or line crossing. This is mainly useful for push notifications to your phone or for the in-built (strobe & audible warnings on some models) to avoid false alarm notifications.

Example Product: DS-2CD2T46G1-4I/SL-2.8MM

Acusense DVRs/NVRs: These recorders allow for similar features to the acusense cameras above but by making use of standard cameras, along with Deep learning-based analytics. These recorders can also display the most recent captured VCA events by target classification to be displayed on the left hand pane of GUI4, replacing where the camera list would usually appear. This allows an 'At a glance' check of events. Replacement of an existing DVR/NVR can be ideal in a situation where a customer already has a CCTV system and just wants to improve the notification side of things.

These iDS recorders work best with 2MP cameras, as this allows more processing power for the Analytics.

The Acusense will work with higher resolutions, but this reduces the number of Analytic channels you have available. In the case of using 2MP cameras then the number of available acusense analytic cameras comes from the number at the end of the model code:


iDS-7204HQHI-K1/2S = 4 channel DVR, max 4MP lite recording, 2 channels of Human Form detection
iDS-7204HUHI-K1/4S = 4 channel DVR, max 5MP recording, 4 channels of Human Form
iDS-7208HUHI-K2/4S = 8 Channel DVR, max 8MP recording, 4 channels of Human Form detectionM models : There is already a 2nd Generation of Acusense DVRs (M model DVRs - which we don't stock yet), these have an added channel of face detection alongside the afore mentioned Human and Vehicle detection, allowing for snapshots to be captured when whenever a face is detected on that chosen channel. The snapshots are displayed next to the live view on GUI4.
Model example: iDS-7208HUHI-M2/S  - 8ch DVR, 1ch Face detect, 4ch human/vehicle detect (god knows why they didn't use M2/4S as the coding!)PIRL Turbo Cameras: Almost like the Acusense of the Turbo Cameras. These are TurboHD Cameras with a 'double knock' false alarm filtering and area available in 2MP or 5MP. These cameras can be set up so that the the basic motion events only trigger when the in built PIR is also triggered. This combination of triggers greatly reduces recording and notifcations from false alarm such as weather, leaves, shadows, lights. These cameras can also have the motion+PIR combo trigger an in-built LED/strobe to grab anybodys attention and highlight they are being monitored, thus increasing their level of detterence.

Example Product: DS-2CE71D8T-PIRLO

*Please note PIR doesn't add anything to the Intrusion or Line Crossing analytics of the DVR (yet), the PIR just works alongside basic motion.Turbo X Cameras: Again, these Turbo Cameras have a 'double knock' false alarm filtering as above. This time the double knock effect can be made to trigger a Flashing strobe and Audible Siren, this is useful for perimeter protection (or just scaring the postman!). The Siren & Strobe can be configured within the lighting plan section of the motion event page on the DVR (iDS, HQHI-K, and HUHI-K recorders). The additional bonus is the full colour night time feature as previously mentioned in our ColorVu post.

Example Product: DS-2CE72DFT-PIRXOF

*Please note TurboX doesn't add anything specifically to the Intrusion or Line Crossing analytics of the DVR, the PIR just works alongside basic motion. If Human Form detection is a specific feature then use an iDS recorder.

By using the above products appropriately it is possible to narrow down your notifications so they do not become ignored, and will help with looking back to find relevant footage. As always, keep an eye on firmware updates which will further enhance features with these newer products.

Please take a look at the below time lines for a comparison of a Turbo X camera with false alarm filtering against a standard camera using basic motion:

The top time line is taken from a camera using basic motion detection and will be affected by rain, snow, leaves, shadows, birds, etc. This motion based recording is still saving on valuable hard drive space, but for finding footage it still has quite a lot of random events that were triggered from the motion, this would be worsened by adverse weather such as snow which would constantly trigger the motion.

The bottom time line from the same location at the same time from a Turbo X Turret with false alarm filtering being used. The pink markers now only show when the PIR and motion is triggered together to give that double knock effect. I can be pretty certain that for each of those markers that a person will be in th event clip, which is ideal for  looking back at the footage.

False Alarm Filtering

False Alarm Filtering

The false alarm filter setting within the DVR will only show if the recorder detects that the camera has the additional PIR sensor, this enables the double knock effect. An additional option for lighting plan will appear below this option for Turbo X cameras, allowing you to set a schedule for the flashing lights and siren.

The below video shows an example of the Turbo X Turret camera when the lighting schedule is set and triggered by the PIR and motion together to trigger the in built light and siren:

So, in summary the above options allow for a multitude of flase alarm filtering options.If a customer already has a system in place whether it is TurboHD or IP then replacement of the recorder to an Acusense DVR or NVR can make use of the existing cameras and reduce alarm notifications on up to 4 areas. Conversely, if customers would prefer to keep their existing NVR, Hikvision AcuSense IP cameras can be added to the solution.
