Note the difference in rolling circumference:

Rolling circumferences are generally approved in the range +1.5% und -2.5% g. Please check with the responsible inspector beforehand.

Speed deviation outside the norm:

In EU countries, the speedometer may display a maximum of +10 % + 4 km/h and no km/h less than the actual speed driven.

Blue Iris Vs Hikvision Nvr 2021 -

Hikvision uses the platform for remote viewing, which functions similarly to consumer-grade systems like Ring or Nest but with commercial-grade backend security.

: Superior motion detection, AI integration (DeepStack/CodeProject.AI), and web-based remote access.

This article will break down the pros, cons, performance, and costs of each to help you decide which is right for your project.

Modern Hikvision NVRs feature built-in AcuSense AI, which filters out up to 90% of false alarms by specifically categorizing human and vehicle targets. blue iris vs hikvision nvr

Blue Iris integrates deeply with DeepQuest and CodeProject.AI. This allows for incredibly accurate, locally processed AI facial recognition, license plate recognition (LPR), and object detection (distinguishing a human from a blowing leaf).

Blue Iris relies heavily on the host computer's processor. Historically, it was notorious for maxing out computer CPUs. However, modern optimizations have shifted the paradigm:

To run Blue Iris correctly, you cannot use an old laptop. You need a desktop with a decent Intel CPU (QuickSync is vital for smooth decoding). Hikvision uses the platform for remote viewing, which

You prefer standard monitor setups (HDMI out directly to a TV or security desk).

You can customize frame rates, recording schedules, detection zones, and alerts with granular detail.

Setting up these two systems requires completely different technical skill sets and initial workloads. Modern Hikvision NVRs feature built-in AcuSense AI, which

Choosing the right Network Video Recorder (NVR) system is the most critical decision you will make for your property's surveillance. It dictates how your cameras perform, how reliable your storage is, and how easily you can access footage during an emergency.

Blue Iris can leverage Intel Quick Sync (built into Intel CPUs) or NVIDIA graphics cards to decode video streams efficiently.

Both systems will record high-quality video. The decision is whether you want to be the one in full control of the software and its complexities, or you prefer a powerful, dedicated system that manages the intricacies for you.

It acts as a universal translator. You can mix and match almost any camera brand (Hikvision, Amcrest, Dahua, Reolink, Axis) as long as they support standard protocols like ONVIF or RTSP. Hikvision NVR: The Dedicated Appliance

A dedicated Windows PC running 24/7 consumes significantly more electricity than a streamlined NVR, leading to higher utility bills over time.

Tire diameter
Tire diameter:
Diameter of the tire.
Rolling circumference
Calculation incl. load from the vehicle and at a speed of approx. 60 km/h (40 mph) (tire circumference * 0.97).
Tire circumference
Purely calculated circumference of the tire without mounting on a rim and without load.
Tire height
Height of the sidewall of the tire.
Rim size
Rim size:
Diameter of the rim.
Rim width
Rim width:
Width of the rim.
Poke (Outer Edge)
Distance between the OUTER rim edge and the contact surface of the brake disk or brake drum.
Inset (Inner Edge)
Distance between the INNER rim edge and the contact surface of the brake disk or brake drum.
Change in ground clearance
Value by which the vehicle is higher or lower with the new tires.
Changing the rolling circumference. If the deviation is too high, it may be necessary to adjust the speedometer.
Displayed speedometer value with desired tires, which corresponds to the displayed 100 mph or km/h with existing tires.
Change outer edge per side
Distance between the outer surfaces of the rims. The rims in the wheel housing move inwards or outwards by this value.
Change inside edge per side
Distance between the inner surfaces of the rims. The ET (offset) has an influence on this value.
