2nd Gen AcuSense Features Motion Detection 2.0 with Other VCAs for Added Precision


False alarms are a big security industry problem. Traditional motion-detection technology is notorious for causing false alarms, which results in time and money wasted on unimportant events. Hikvision’s AcuSense 2.0 PCI models are cost effective and support Motion Detection 2.0, a new motion detection feature that works with other VCA functions for added precision. The result is a technology that helps mitigate incidents, protect your property perimeter, and reduce false alarms.

AcuSense 2.0 provides precise detection of targets in any environment. By accurately sensing human and vehicle movement versus non-human objects such as rain, animals and leaves, AcuSense offers more effective intrusion detection and greatly reduces false alarms.

The 2nd generation of AcuSense products (PCI models) deliver higher accuracy, have a wider variety of camera form factors, and feature more VCAs (video content analytics). Smart VCAs include perimeter detection functions (line crossing detection, intrusion detection, region entrance/exit detection) and work simultaneously with the Motion Detection 2.0 feature.
AcuSense 2.0 models host several other key features:

  • Reduce Time & Cost: False alarm reduction means less time and money spent responding to false alarms.
  • Quick Search: Automatically identify people or vehicles in motion detection playback mode, eliminating manual searches.
  • False Alarm Filtering: False alarm filtering performs even in harsh weather conditions like rain and snow.
  • Customized Audio Message: Can be recorded and uploaded through the Hik-Connect app.
  • Strobe Light and Audio Alarm (SL Models only): Additional alerts to enhance deterrence. Audio alarm and strobe light versions support two-way audio. Using the strobe light and siren feature on an alarm makes it easier to identify and, in turn, apprehend an intruder.
  • Extended Monitoring Area: Makes it possible for one guard to handle multiple alarms, since AcuSense filters out movement of non-human objects.
  • Easy Configuration: Allows users to enable a video analysis rule easily and quickly.
  • Simplified installation: No need for another power cable or adapter for external device which requests a 12 VDC power supply (Max 0.1A, non-L model)

Our first generation AcuSense 1.0 models have basic motion detection that works separate from other VCAs.

IMPORTANT! This model requires non-standard firmware. Do Not Install standard firmware (e.g. v.4.1.xx) on this model. Doing so will permanently damage your system. You must use custom firmware v.4.1.25 from the iDS-9632NXI-I8/16S product page.

The I-series NVR (such as the DS-7716NI-I4) is one of Hikvision's most popular and feature-rich recorders. As such, many firmware revisions have been introduced over the years to continually ensure the product is compatible with the newest technology available. Due to the many revisions, we recommend that the user closely follows the instructions below in order to reduce the amount of time spent as well as the chance of failure.


Database Optimization and Repair

As more affordable IP cameras are introduced over time with greater video resolution and data sizes, more efficient database management also becomes necessary. The introduction of firmware v4.0 brought about a new database architecture in order to be futureproof.


After upgrading to v4.X, the recorder database will need to be converted and optimized. If you are experiencing issues where playback is expected but not found, make sure "Database Repair" is performed as indicated in the procedures and scenarios below.


Preparing the Upgrade

Before proceeding with upgrade, it is recommended that NVR configuration file is exported from the NVR over the network or on to a local USB drive.


Upgrading from v3.4.92 build 170518 or Older

  1. All recorders must reach v3.4.92 before proceeding further. Upgrading from versions before v3.4.92 directly to any version of v4.X will likely cause the recorder to fail.
  2. If the recorder is already at v3.4.92, a full factory default is highly recommended before upgrading to any version of v4.X. There is a high chance of unit failure (requiring RMA) if the unit is not defaulted before upgrade.
  3. After reaching v3.4.92 and performing a full factory default, an upgrade directly to v4.50.00 is acceptable.
  4. After the upgrade is completed and the recorder is reprogrammed, it may be beneficial to perform a Database Repair. For details, refer to the section "Database Optimization and Repair" above.
  5. To verify repair progress, you may refer to the HDD status, or search the recorder log for repair started and stopped entries. Note that while the HDD is repairing, new recordings are still being made, but some existing recordings may not be searchable until repair is complete.
  6. If you continue to observe playback issues after database repair, ensure there are no power, network, or motion detection issues. Should the problem persist, contact technical support.


Upgrading from Any v4.X Build to v4.50.00.

  1. Any v4.X build can be upgraded directly to v4.50.00.
  2. Export configuration is highly recommended before performing the upgrade.
  3. If upgrading from any v4.X version that was not v4.22.005, a Database Repair is recommended. Refer to Step 4 and onwards in the previous section.



Downgrading is not recommended. Due to new features and parameters constantly being added, downgrading may cause the NVR to factory default itself or require a manual default to operate properly.
