Multicast video transmission vs. Unicast video transmission methods

When looking for the most effective way to manage video in a security system, there are two often-discussed video transmission methods: Multicast and Unicast. Both have their benefits, but which is best for security applications?

Multicast is a method of one-to-many transmission which is often deployed in IP applications of streaming media. Multiple viewers can simultaneously tap into a single transmission from one source.

Television programming is a perfect analogy. When you want to watch HBO you tap into the HBO feed on the cable network, not to a dedicated signal of HBO. If your cable box is authorized, you get access to the existing stream of HBO on the cable network.

To benefit from Multicast, multiple simultaneous views of the same stream are required. For customers who have multiple operators viewing the same live cameras, Multicast may be a benefit.

However, in most security applications, Network Video Management Systems (NVMS) are used to view recorded video much more than live video, like reviewing video from a specific date and time, around an alarm event, or reviewing video as part of an investigation. Since all recorders, including the most advanced multicast-based recorders, are based on Unicast video streaming for playback, there really is no gain on operation performance by utilizing Multicast network.

To realize significant benefits from Multicast transmissions, a multicast-enabled network must be constructed to enable single stream replication on the IP network, making it available for every user looking to view it.

Multicast stream can only be used on the Local Area Network. Operators communicating over a wireless connection or over the corporate WAN will communicate using Unicast stream by default, and will not gain from the Multicast capability. In addition, IT departments are wary about enabling Multicast on their network due to security reasons, not to mention the cost associated with it.

Is Unicast a better option?

With Unicast transmission, every user in the network who would like to view video will receive a dedicated video stream from the Video Management System (VMS). Compared to Multicast transmission, Unicast does utilize more bandwidth; however, these streams are only required between the source and the “viewer”, and do not affect the entire network (as a Multicast transmission would.)

With VMS implementation of advanced video compression technology and the ability to maintain symmetric bandwidth management of video, users can manage multiple high-quality video streams on a Unicast network without the deployment of Multicast transmission.

To summarize, Multicast transmissions do offer the benefit of lower bandwidth consumption, but comes with higher network construction cost.  Unicast provide cost-savings on the construction of Multicast-enabled networks while maintaining real-time, low latency, high-quality video with adequate bandwidth management for all users on the network.

Drive Faster Business Throughput by Scanning

 

nc_007051

It’s amazing how quickly a business process gets bogged down when you have to search for paper documents. It doesn’t matter if you are a Fortune 500 company, a local school or a small manufacturing company.

A common trouble spot is the purchasing process. Let’s start with receiving a purchase order (PO) from a customer. That might come in as a fax, through the mail or maybe as an email attachment. Someone takes the paper PO and generates a sales order. That creates a shipping document that goes to the warehouse.

Products are packaged and sent through a carrier with a list of what’s shipped. After the product shipped, you receive a proof of delivery from FedEx, UPS or whatever shipping company you use. Now you create an invoice and send that to the customer. Each printed document is collated and goes into a customer file. There should only be one version of each document, but there might be multiple copies in files throughout the company.

The customer calls with a question about their shipment. The sales rep is contacted, but he doesn’t have the shipping list. He calls accounting, but they didn’t get the final list from shipping. He calls shipping, but everyone is busy with a big order. While he’s tracking down the information, the customer gets frustrated.

A better approach is to scan the paper documents into a document management system so everyone can access the same information quickly. When the PO comes in, the person receiving it walks up to an MFP (multi-function printer) and scans it into a customer folder. A notification generates a sales order. A shipping document is printed and sent to the warehouse. The order is packed and a shipping list printed. Everything is scanned into the customer folder, including the proof of delivery when it arrives.

When the customer calls, the sale rep opens a browser, types in the customer name and sees all the documents in one place. He answers the customer’s question quickly and she is happy.

Scanning documents eliminates errors and saves time, which translates into a satisfied customer. That’s something we all need.

Let MCC help your organization’s run smoother and become more organized. Contact us today for a consult on which MFP is the right solution for you.

The Value of Digital Video Recording Products

SS_Intellex_16GUI[1]

Many times, we take our security for granted, breaches in security occur every day, 24/7, spanning everywhere around the world. The majority of recorded surveillance video is rarely viewed until an event occurs. Video recorders are generally a second thought, as they record captured images that provide forensic analysis. It is only when an event, incident, or catastrophe occurs that the power and value of video recording equipment is displayed.

Video surveillance market research firms are predicting a spike in the demand for video surveillance equipment over the next several years as swift apprehension of suspects is attributed to video images capturing suspicious behaviors.

And even as the security industry is undergoing a transition in technology from analog to IP, digital video recording (DVR) systems continue to see a future for two very simple reasons: Familiarity and Reliability. DVRs have been the prevalent recording platform in the industry for more than a decade. There is a very large base of DVR customers, with end users and integrators alike, well trained on these systems. While many NVRs (network video recorder) are being installed, DVRs continue to see growth in several market segments such as education, banking, and hospitality. In some circumstances, end users who want or need to add cameras or replace a failed DVR will continue to invest in the platforms they know and trust, especially if there is no need to move to an IP environment.

DVR systems offer great reliability with some of the same strong features seen in the newer NVRs, including mobile apps that can be used with both new and older versions of DVRs. Having the ability to view video anytime from anywhere is a driving factor for users today.

Ease of installation and universal plug-and-play interoperability with any analog camera is another reason that DVRs continue to maintain their popularity. There are several thousand DVR systems that are in use in almost every market segment. DVRs can interoperate with any vendor’s analog cameras, making the installation and equipment choice relatively straightforward for many users. The experience that the installation force has developed with the DVR platform continues to be a major factor in their continued use.

Over time we will undoubtedly see a transition from DVRs to NVRs. As in many other industries, technological advancements will be a driving factor. But for now, we continue to see applications where DVRs are still the platform of choice for many. How long DVRs will remain viable in the security industry is anybody’s guess. But as long as they continue to provide value to their users, they will continue to have a place in the industry.

Understanding the Importance of Data Management

 

dbms

Many companies may see collecting more data as the solution to all of their client communication problems. While an increase in volume does mean that the business is gaining new customers, it is also important to realize which information is actually relevant. Data management solutions allow organizations to clean their systems and get rid of the unnecessary data clogging their computers. There are certain measures that companies can take to move forward with accurate information and have successful client communication. Understanding what causes bad data and implementing better information collection practices will help eliminate the problem altogether.

Why clean out databases?
Data expert Dylan Jones says one of the most prominent reasons poor data exists is because businesses are gathering too much irrelevant material. Information that can’t be used should not be taking up space in a database and needs to be addressed promptly. Unfortunately, organizations are still storing this useless data and failing to see how it is causing problems. High-quality contact data needs constant attention and should take precedence over all other kinds of customer information. This is not possible if companies have to clean data that they are not going to put to good use.

Making data cleansing a priority, as well as ridding the database of any irrelevant information, is beneficial for companies in the short- and long-term. Jones says some of the major advantages of cleansing the system correctly is opening up space and freeing the computer or core user from the weight that could be dragging it down. A slow system can lead to negative implications throughout the rest of the organization and, ultimately, monetary losses. Eliminating poor data improves procedures across the board and allows employees to do their jobs effectively.

How to achieve success
It is okay for companies to desire bigger, better data, they just have to make sure their systems are reliable and that they can put a higher volume of data to good use. IT Web Business admits that a majority of businesses focus on collecting as much customer information as possible. The source questions whether that data has an actual purpose, though. Information must be structured and organized for businesses to use it. Quality over quantity is the most important thing to remember, and organizations that have a plan of attack for their data are going to see more success in the long run.
