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.
exacqVision 7.0 introduces Camera Links, which allow exacqVision users to configure overlay controls that will display when hovering over a camera in live view. Camera Links give exacqVision Professional and Enterprise users the ability to put their most important commands at their fingertips and improve their response time to critical alarms and events.
Camera Links are completely customizeable. Users can adjust the text color, font, style, transparency and location on screen to fit the specific camera view needs from the camera settings page. Under the associations tab, users can select the available controls, associated controls and display options.
The overlay controls include:
Audio inputs and outputs
EasyConnect Status Messages
The EasyConnect feature on the exacqVision VMS software allows users to find, assign, address and connect certain IP cameras to their network automatically. Camera connection in exacqVision 7.0 has been improved to show more detailed connection status feedback when connecting Illustra IP cameras and exacqVision E-Series encoders. There are now more than 20 unique status messages. Each message is color-coded for fast identification of issues. Users can hover over the status for troubleshooting guidance. Connection messages include:
Duplicate IP address
Address not responding
Address found but device not responding
Video not streaming
Camera time unsynchronized
Having comprehensive, specific information regarding the connection and the suggested troubleshooting guidance saves users time and money during installation.
The exacqVision client can now be configured to automatically check for new updates. To enable the automatic check, go to the “About” button in the client and check the new option, “Automatically check for updates.” The client will check 30 seconds after it opens for new updates.
Visual Hard Drive Storage Status
exacqVision 7.0 adds a graphical representation of hard drive status for exacqVision systems equipped with RAID storage such as the exacqVision Z-Series, A-Series and S-Series. When a drive failure occurs, exacqVision users will see a display that indicates the physical location of the drive that needs replaced, minimizing the risk of removing the wrong drive. Go to the storage page under the hardware tab to see the graphic assessment of the hard drive status.
Several improvements to Exacq mobile have been added in this release including event monitoring and two-finger swipe capabilities.
The Exacq mobile app now supports viewing event monitors that have been configured within the exacqVision client. Event monitoring ensures mobile app users are aware of the most important video relating to events like motion detection, alarms and other triggered inputs to the system.
Exacq mobile also introduces a new two-finger swipe navigation for faster review of all camera views. Users can swipe to the left to load the next set of cameras into the viewing layout.
The web client now has a server configuration page for monitoring and managing servers.
Enterprise System Manager (ESM) ESM Bulk Save Server Configuration
Administrators can back up the settings of all exacqVision servers across the enterprise at one time. Users can also specify which servers are backed up with a filter.
ESM Open and Unacknowledged Events
View all open events as well as new, incoming unacknowledged events within one dashboard in ESM. This prevents the user from switching back and forth from two different lists. Under the list section in the dashboard is a new option “Open or Unacknowledged Events” which includes both lists into one.
ESM Filter Indication
ESM users can see a visual indication when filters are active on a page. This icon prevents a user from getting confused why all results are not showing. A new clear filter button allows users to clear a data filter without having to open the filter dialog.
New IP Camera Support
We have added support for more than 75 new IP camera models in the exacqVision 7.0 release and updated over 240 test records. exacqVision now supports nearly 3,000 IP cameras.
The latest versions of exacqVision client and server software can easily and quickly be copied over existing versions while retaining all user settings. The latest versions are available through “Check for Updates” in the “About” box in the exacqVision software.
exacqVision Server software is available in both Windows and Linux versions, and the exacqVision client software is available in Windows, Linux and Macintosh native versions. Any version of exacqVision client can connect to any version of exacqVision server.
Challenged with patrolling a large area and protecting thousands of residents and hundreds of businesses, local governments and police departments need an efficient video surveillance system. Today, municipalities face a variety of new security challenges including geographical disparity, scalability and remote monitoring.
Government and municipal projects often have tight budget restraints and require a cost-effective surveillance system that covers a large area while providing expansion opportunities for future security needs.
Union City, N.J., and Prospect Heights, Ill., are two cities that have recently implemented cost-effective video surveillance systems. As a result, each city has seen a reduction in crime rates and a vastly improved public safety system by considering the following elements in their solution.
View Video Remotely
To provide a successful municipal surveillance system, find a video management system (VMS) software that law enforcement officials can easily use remotely. Police departments need to view live and recorded video from their desks, phones or vehicles from anywhere throughout the city, day or night.
Prospect Heights Police Department strategically placed cameras in the highest risk public areas. With exacqVision VMS software all government officials can download the free Exacq mobile app or run the free client software on any web browser. This allows them to assess situations as they are happening and provide guidance to on-the-scene officers. Additionally, the exacqVision software has given them the opportunity to monitor their risk, assess the environment they are entering and prioritize issues immediately from their devices. Remote video monitoring enhances situational awareness, enabling them to respond quicker and more effectively at crime scenes.
Implement a Wireless Solution
When tasked with monitoring a city consisting of thousands of residents, consider implementing a wireless mesh network for the most effective security system. In Prospect Heights, Illinois, the surveillance system acts as a force multiplier, allowing the police department to keep more officers patrolling the streets and letting the cameras cover high crime areas. With this solution, video from the cameras is transported wirelessly to a nearby building and then transmitted to the police station over the secured network. The wireless system connects the police department with the community areas for real-time viewing of activities. By leveraging this capability, Prospect Heights can monitor crime in neighborhoods without the need for full-time police officers to constantly patrol the area.
Be Resource Efficient Replacing an entire security system can be very expensive. As an alternative, law enforcement officials can leverage their current infrastructure, wiring and analog cameras while also updating their security system. This maximizes the initial security investment while providing the flexibility to upgrade the system later. Union City, N.J. was able to utilize their existing analog infrastructure while also adding new technology, while Prospect Heights Police Department fully integrated the surveillance system with their broadband wireless network to better leverage resources.
Find an Easy-to-Use VMS Software Simplify the process of searching and exporting video by selecting an easy-to-use VMS software. Most police departments and local governments suffer from lack of time and limited resources. The exacqVision client greatly improved operations and reduced investigation time for Prospect Heights Police Department. In the event of a reported crime, police officers can use the exacqVision VMS software for post-incident investigation and research. Officers can quickly search the exacqVision client for the time of the incident and can then export real-time evidence and footage to be used in court if necessary. Chief of Police Jamie Dunne noted, “The exacqVision software has allowed us to quickly capture video clips of incidents that we have used to bring criminal investigations to successful conclusions.”
Prepare for Future Growth Communities continually grow and crime hot spots change. Therefore, municipalities need to be forward thinking when designing a security solution. Scalable solutions provide an easy method to add cameras and expand the security system as the population demographics adjust. Prospect Heights initially designed their wireless security solution with future additions in mind. They accounted for the ability to add cameras moving forward and adjust the system as needed.
