Hikvision’s new modular IP video intercom solution enables you to greet visitors and control building access from anywhere. See, hear, speak and grant access to people at the door from the new indoor stations and a smartphone or tablet using the free Hik-Connect app.

The main door station unit provides video intercom functionality with one name tag and call button. Up to eight additional modules can be connected to the main unit. The name tag module provides six additional name tags and call buttons. The card reader module allows door unlock using RFID cards or fobs. The keypad module allows dialing more than 500 rooms as well as passcode access. The display module lists the contacts that can be selected and called. There are surface and flush mounted frames that hold two or three modules vertically, and multiple frames can be mounted adjacently.

Hikvision’s intercom solution provides the following key benefits:

  • Clear audio-visual communication:
  • Communicate clearly with noise and echo cancellation
  • Door station camera provides a Full HD, 180-degree wide field of view
  • See clearly day and night with true WDR and IR night vision

Easy to use for multiple applications:

  • Intercom, doorbell, multi-tenant video entry and monitoring functions
  • Receive calls from visitors and unlock the door on indoor stations via smartphone or tablet using the Hik-Connect mobile app
  • Call room-to-room between indoor stations and iVMS-4200 software
  • Monitor additional surveillance cameras on the indoor station
  • Record door station video with motion detection on your Hikvision NVR/DVR

Simple to install:

  • Standard PoE switches can connect and power the whole system
  • Indoor stations can also connect via Wi-Fi with 12 V power
  • All door station modules can be surface or flush mounted
  • Simplified configuration gets you started in minutes

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.
