IP video innovates access

Published

on

Integration between video management systems (VMS) and access control systems (ACS) will soon offer the ability to incorporate ACS access and biometric data with video surveillance footage. But there are some pitfalls to look out for, writes MARC VAN JAARSVELDT.

Currently, there are integration options available, but not all solutions offer a seamless link-up of the traditional ACS data with the IP network. This is according to.

There are some convincing implementations locally, where the integration is solid and results are positive. We have no doubt that the integration will improve over time, but for now users need to be aware of the pitfalls.

What is making a difference and an impact on the ACS market is the continued growth and acceptance of IP networking as the de facto standard for video management systems. “We have seen that several access control (AC) vendors have started to offer IP interfaces with their hardware because of the prevailing nature of the network-based security technology. Some examples are Suprema, which produces biometric units with IP interfaces and Genetec that offers an end-to-end AC plus VMS system, including hardware and full integration.

Typically the AC unit (a car or fingerprint reader)) is IP enabled and uses a UTP network cable to allow communication with the LAN, but it still retains traditional signaling interfaces like Wiegand or RS485, which need to be wired in via an IP enabled controller. Examples of these devices are made by Axis, a market leader in network video. In some cases the IP link-up happens where the main AC controller resides, but door units are still wired the traditional way. Even though there are various levels of integration, the ability to incorporate AC data with video surveillance footage has changed the game plan somewhat for ACS vendors. It has also had a positive impact on the role of biometric data within an overall VMS.

The main advantage of this approach is that it allows biometric data or AC information to be extracted and displayed on a suitable PC. It is here that the VMS comes in. Once that IP interface is available, developers can write a specific software program to interrogate the AC device and bring biometric or simple access data into the VMS and incorporate it with video.

The data will be included with the video footage, providing a deeper layer of security information as the video system now displays all AC data including personnel information, credentials and video images. This enhances security and situational awareness. The great thing is that in this instance, operators are now using a single interface for video and AC, as opposed to separate interfaces.

An example, he says, is that you are not just viewing a person as they enter the building, but now having access to all the data about that individual embedded or included with the video. In doing this, companies are able to set up alarms that allow for rule or exception management, which is a powerful security tool.

Integrated ACS and VMS systems are no longer science fiction. They are an important part of the future of the security industry. Locally, we still have a long way to go to get the integration with VMS seamless and deliver acceptable outcomes. Companies need to understand and have a quality VMS system installed first, and then work towards adding value and extra layers of security such as the integration of AC.

Tips for choosing your system:

1. Choice of VMS and ACS is critical because it will define which hardware can be integrated. Most VMSs offer basic AC integration with a very limited sub-set of brands.

2. Realise that there is intelligent integration where the door or biometric unit integrates fully with the VMS and all of its functionality is supported versus un-intelligent integration where the unit communicates with the IP LAN via a simple controller that allows the RS485 cable to be plugged in. These will only support basic functionality and limited data integration.

3. With very long cable runs, or in very noisy environments, you may need to stick with traditional RS485 and cabling and link to the IP network on the backend.

4. When the integration plug-in is written by a 3rd party company (as is often the case), keep in mind that VMS version upgrades or ACS firmware upgrades can break the inter-device communication.

Money talks and electronic gaming evolves

Computer gaming has evolved dramatically in the last two years, as it follows the money, writes ARTHUR GOLDSTUCK in the second of a two-part series.

The clue that gaming has become big business in South Africa was delivered by a non-gaming brand. When Comic Con, an American popular culture convention that has become a mecca for comics enthusiasts, was hosted in South Arica for the first time last month, it used gaming as the major drawcard. More than 45 000 people attended.

The event and its attendance was expected to be a major dampener for the annual rAge gaming expo, which took place just weeks later. Instead, rAge saw only a marginal fall in visitor numbers. No less than 34 000 people descended on the Ticketpro Dome for the chaos of cosplay, LAN gaming, virtual reality, board gaming and new video games. 

It proved not only that there was room for more than one major gaming event, but also that a massive market exists for the sector in South Africa. And with a large market, one also found numerous gaming niches that either emerged afresh or will keep going over the years. One of these, LAN (for Local Area Network) gaming, which sees hordes of players camping out at the venue for three days to play each other on elaborate computer rigs, was back as strong as ever at rAge.

MWeb provided an 8Gbps line to the expo, to connect all these gamers, and recorded 120TB in downloads and 15Tb in uploads – a total that would have used up the entire country’s bandwidth a few years ago.

“LANs are supposed to be a thing of the past, yet we buck the trend each year,” says Michael James, senior project manager and owner of rAge. “It is more of a spectacle than a simple LAN, so I can understand.”

New phenomena, often associated with the flavour of the moment, also emerge every year.

“Fortnite is a good example this year of how we evolve,” says James. “It’s a crazy huge phenomenon and nobody was servicing the demand from a tournament point of view. So rAge and Xbox created a casual LAN tournament that anyone could enter and win a prize. I think the top 10 people got something each round.”

Blockchain unpacked

Blockchain is generally associated with Bitcoin and other cryptocurrencies, but these are just the tip of the iceberg, says ESET Southern Africa.

Published

on

This technology was originally conceived in 1991, when Stuart Haber and W. Scott Stornetta described their first work on a chain of cryptographically secured blocks, but only gained notoriety in 2008, when it became popular with the arrival of Bitcoin. It is currently gaining demand in other commercial applications and its annual growth is expected to reach 51% by 2022 in numerous markets, such as those of financial institutions and the Internet of Things (IoT), according to MarketWatch.

What is blockchain?

A blockchain is a unique, consensual record that is distributed over multiple network nodes. In the case of cryptocurrencies, think of it as the accounting ledger where each transaction is recorded.

A blockchain transaction is complex and can be difficult to understand if you delve into the inner details of how it works, but the basic idea is simple to follow.

Each block stores:

–           A number of valid records or transactions.
–           Information referring to that block.
–           A link to the previous block and next block through the hash of each block—a unique code that can be thought of as the block’s fingerprint.

Accordingly, each block has a specific and immovable place within the chain, since each block contains information from the hash of the previous block. The entire chain is stored in each network node that makes up the blockchain, so an exact copy of the chain is stored in all network participants.

As new records are created, they are first verified and validated by the network nodes and then added to a new block that is linked to the chain.

How is blockchain so secure?

Being a distributed technology in which each network node stores an exact copy of the chain, the availability of the information is guaranteed at all times. So if an attacker wanted to cause a denial-of-service attack, they would have to annul all network nodes since it only takes one node to be operative for the information to be available.

Besides that, since each record is consensual, and all nodes contain the same information, it is almost impossible to alter it, ensuring its integrity. If an attacker wanted to modify the information in a blockchain, they would have to modify the entire chain in at least 51% of the nodes.

In blockchain, data is distributed across all network nodes. With no central node, all participate equally, storing, and validating all information. It is a very powerful tool for transmitting and storing information in a reliable way; a decentralised model in which the information belongs to us, since we do not need a company to provide the service.

What else can blockchain be used for?

Essentially, blockchain can be used to store any type of information that must be kept intact and remain available in a secure, decentralised and cheaper way than through intermediaries. Moreover, since the information stored is encrypted, its confidentiality can be guaranteed, as only those who have the encryption key can access it.

Use of blockchain in healthcare

Health records could be consolidated and stored in blockchain, for instance. This would mean that the medical history of each patient would be safe and, at the same time, available to each doctor authorised, regardless of the health centre where the patient was treated. Even the pharmaceutical industry could use this technology to verify medicines and prevent counterfeiting.

Use of blockchain for documents

Blockchain would also be very useful for managing digital assets and documentation. Up to now, the problem with digital is that everything is easy to copy, but Blockchain allows you to record purchases, deeds, documents, or any other type of online asset without them being falsified.

Other blockchain uses

This technology could also revolutionise the Internet of Things  (IoT) market where the challenge lies in the millions of devices connected to the internet that must be managed by the supplier companies. In a few years’ time, the centralised model won’t be able to support so many devices, not to mention the fact that many of these are not secure enough. With blockchain, devices can communicate through the network directly, safely, and reliably with no need for intermediaries.

Blockchain allows you to verify, validate, track, and store all types of information, from digital certificates, democratic voting systems, logistics and messaging services, to intelligent contracts and, of course, money and financial transactions.

Without doubt, blockchain has turned the immutable and decentralized layer the internet has always dreamed about into a reality. This technology takes reliance out of the equation and replaces it with mathematical fact.
