Hikvision HDTVI Long Distance Problem Tested

By: Ethan Ace, Published on Feb 05, 2015

Hikvision's HDTVI cameras performed poorly over low quality or long coax and UTP cables in our original tests. This was a major issue as a key selling point of analog HD technologies is reuse of existing cables.

Now, a few months later, they have released updated chipsets and camera firmware claiming to better support these cables. We tested cameras including these additions head to head with previous models to see if performance has improved. 

Here, we cover:

  • High quality cable performance (new vs. old chips)
  • 1000' coax performance
  • 1000' Cat5e UTP performance
  • How to tell what generation your cameras are

In the comparison test of the 25' cable which is factory terminated, the older chipset looks much more natural. Also license plate is sharper. For the longer cable runs I do definetly notice the improvements

This is the most important side by side IMO. UTP vs COAX.

Is the old firmware compatible with the new chips and vice versa?

If not compatible, can we tell just by which firmware we have which chips we have?

Chris-yes, there are no old/new compatibility issues either way. Only with new/new do you get the extended distance benefits. I will post version information as soon as it is available.

Is it a safe assumption that HIK only shipped new chips with new firmware?

Meaning that if someone has old firmware they would have (unless they rolled back) old chips.

Can the improvement be made with just the firmware update? Or is the new chip required with the new firmware?

Only with new/new do you get the extended distance benefits. - Bob Germain
