Hikvision Launches DarkFighterX Low Light Surveillance Technology

Hikvision announced the launch of its new DarkFighterX technology that delivers sharp, colorful images in low light conditions.

Hikvision’s DarkFighterX security camera improves upon its DarkFighter technology by providing colorful, sharp images in low light to 0.001 lux, according to the corporate product release. The DarkfighterX series includes a PTZ and bullet camera, which both feature optical defog, 25 times optical zoom, 2MP resolution, and smart detection.  

“Faces are sharper and easier to recognize and the surroundings much clearer to see, even in the lowest light. All of this makes images much more valuable for evidence collecting and case solving,” said Peter Guan, Hikvision channel sales director in the press release. Guan added that the majority of crimes happen at night.

“Hikvision’s original DarkFighter technology delivers low-light color imaging, but the new DarkfighterX brings it to a completely new level,” said Jeffrey He, president of Hikvision USA, Inc. and Hikvision Canada, Inc. in an interview with leading security publications SecurityInfoWatch.com and SD&I. “It’s one thing to be able to see low-light color images, but to be able to see the color of clothes or color of a vehicle at night enables true 24/7 surveillance.”

Just as the human eye collects color and brightness to merge into a full color picture, DarkFighterX captures information from the IR sensor for brightness and  from a visible light sensor for color, then combines them to create a bright, full-color image.

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

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.
