Multicasting vs. Multistreaming in IP Video Surveillance Deployments

One of the advantages of IP video vs. analog CCTV is the distribution flexibility of IP networks. With IP networks, video can easily be routed anywhere on the network, to one or more endpoints as desired. In turn, users have the potential to over-utilize network bandwidth and compromise the overall performance of the video management system solution.

Drawbacks of Multicasting 
Some consider IP multicasting as the solution to minimizing IP streaming bandwidth, when in actuality the advantages of multicasting are limited to specific scenarios. With multicasting, bandwidth savings only occur when multiple subscribers view the same live video stream. Several drawbacks to multicasting should be considered including:

  • UDP video streaming – UDP does not guarantee every packet gets delivered and it exposes the video stream to any unreliability of the underlying network, resulting in poor video quality due to lost or duplicate packets.
  • Higher complexity – multicasting implementation requires special equipment and knowledge beyond fundamental IP network configuration.
  • Variable bandwidth savings – the amount of bandwidth savings can fluctuate depending how many people request the same content. Multicasting only delivers benefits when the same live camera stream is being viewed by multiple people.


One advantage of multicasting is that only one stream of video from the camera is required to support many viewers.  exacqVision provides this same benefit without the complex configuration. exacqVision is designed to efficiently support many clients viewing live video using only a single video stream from the camera.

exacqVision Saves Significant Bandwidth with Multistreaming
exacqVision is able to deliver significant bandwidth savings through the support of intelligent multistreaming, instead of multicasting. exacqVision will automatically deliver the full resolution stream or low resolution stream based on the viewing need of each client requesting video. Users can override the automatic choice and manually select high or low resolution streams for viewing as needed.

Updated Exacq IP Cameras Webpage Makes Searching Easier

The new Exacq IP cameras webpage allows you to filter by specific features to find all the supported cameras compatible with exacqVision in addition to using the search box. These new search filters make it easier for you to find the IP cameras you are looking for. The new filters include:

  • Megapixel (search for cameras with desired MP resolution)
  • Fisheye
  • EasyConnect (IP cameras compatible with exacqVision EasyConnect)
  • Audio
  • Two-way audio
  • PTZ (Pan, Tilt, Zoom)
  • Analytics
  • Edge
  • Encoder (search for analog to digital video encoders)
  • LPR (License Plate Recognition)
  • Multi-streaming
  • Other Devices (I/O modules, Surveillance Keyboards, etc.)

exacqVision supports more than 2,200 IP camera models from nearly 100 manufacturers. Additionally, you can sort by manufacturer, model, number of streams supported and more. Be sure to view the test results to see all the integration details and functionality.

exacqVision 5.2

New exacqVision 5.2 features include:

  • Hardware Monitoring
    • Monitors motherboard of an exacqVision factory server
    • Use with Event Linking to send email/text alerts
  • Expanded Multistreaming capability
    • Multistream support added for Pelco, Hikvision, Interlogix
  • exacqVision Edge adds support for new ISD cameras
  • Integration of video analytics through exacqVision Event Linking
  • New IP Camera Integration
    • UDP, Riva, ACTi and Interlogix
  • Simplified Video Configuration
    • Easier configuration for Views, Tours, Maps and Groups
  • Video Export Improvements

Hardware Monitoring

Protect your investment. Always know the status of your exacqVision factory servers with the new Hardware Monitoring feature available with exacqVision 5.2. Track the voltage, temperature and fan speed of your motherboard. In the event that any of the measurement values is outside the minimum or maximum range, an ALARM indicator is displayed and can be sent as a notification via email or text message using the exacqVision Event Linking feature.

Hardware Monitoring

Expanded Multistreaming Capabilities

Version 5.2 adds multi-streaming support for Pelco Sarix, Hikvision and Interlogix cameras.

The multistreaming feature (introduced with exacqVision 5) allows the ability to set multiple, independent video streams from the IP camera. Each stream can be set at different frame rates, resolution and quality level, ideal if you require remote viewing over a limited-bandwidth connection, but want to retain the highest resolution for recording and local viewing. Up to four streams per camera can be selected, depending on the IP camera model.

Other supported IP cameras for multistreaming include those from Axis, Arecont Vision, Panasonic and ACTi. Multistreaming is supported in exacqVision Pro, Enterprise, and Edge.

exacqVision Edge Support for ISD Cameras

We have partnered with Innovative Security Designs (ISD) to bring the exacqVision Edge VMS server directly onto ISD cameras. ISD’s unique IP/analog cameras support the SDXC format with up to 128 GB of on-camera storage to create a powerful single camera solution or a vital component of a distributed solution.

Integration of video analytics through exacqVision Event Linking

Most UDP cameras include on-board video analytics. These events can now be linked directly to exacqVision via the Event Linking feature. Use powerful video analytics to trigger alarms, record video or audio, automatically export clips or send notifications via email or text message.

UDP video analytics

New IP Camera Integration


Support has been added for RIVA’s RC100HD, RC1202HD, RC2102HD, RC3102HD, RC3502HD, RC6602HD, RC3302HD, RC3702HD, RC4202HD,
RC4602HD high definition IP cameras. Many of these cameras also support
