IDIS strengthens integrity of video surveillance with critical failover

IDIS has debuted a powerful suite of features designed to bring critical failover capabilities and peace of mind to users of the company’s innovative technology offerings. Bringing together existing, improved and new failover features, IDIS addresses multiple threats to crucial video surveillance operations with IDIS Critical Failover, a collection of five capabilities that strengthen the fault tolerance of end users’ CCTV infrastructure.

“If any part of video surveillance infrastructure fails, it’s critical to first recognise the failure and then initiate appropriate alternative or redundant technologies to minimise loss of data,” noted James Min, managing director of IDIS Europe. “Full redundancy of every component in your infrastructure is prohibitively expensive and adds unnecessary complication in most cases, while manual recognition and resolution costs precious time and risks gaps in footage. IDIS Critical Failover reduces both issues through a multi-layered collection of capabilities spread across the devices in your infrastructure.”

IDIS Critical Failover consists of five parts: Temporary Smart Failover, Smart Failover, Storage Redundancy, NVR Failover and Dual Power Supply.

If you experience a problem with network instability, Temporary Smart Failover starts recording to an internal recording session buffer (of at least 60 MB), ensuring there’s no break in the data being sent to the NVR. For longer network issues, such as a complete failure of the link between the camera and the NVR, Smart Failover takes over. When the IP camera and NVR become disconnected, the camera instantly begins recording to an internal SD card. It records at the original quality until half of the SD card is filled up and then adjusts the quality to ensure a full 24 hours of footage is captured on just a 32 GB card. H.265 cameras add support for SDXC cards, with a theoretical limit of 2 TB. Once the network link is restored, all of the data is automatically transferred to the NVR, leaving no incident unrecorded.

Storage Redundancy exists inside the NVR (DR-8364D) in the form of native RAID 1 or RAID 5 support. With RAID 1 support, the NVR stores two identical copies of the data: if one disk fails, the data is then retrieved from the second one. RAID 5 stores the data and additional parity data in separate locations, providing the same redundancy, but more efficiently than RAID 1.

NVR Failover protects against the failure of the entire NVR. Both the primary and standby NVR continuously monitor one another to quickly switch to the functioning NVR during a failure, reducing the risk of data loss and decreasing failover response times.

Finally, native Dual Power Supplies (DR-8364D) provide a redundant power supply in case the first one fails, increasing uptime and reducing the risk of data loss.

Vista launches new E-Series range with latest Sony Starvis technology

Vista has announced the release of its new range of 3 Megapixel cameras which use Sony Starvis technology, in turn bringing to the fore increased image quality and a “careful balance” between price and performance for security managers.

These new cameras also take advantage of Sony’s Starvis back-illuminated pixel technology to produce highly detailed images in low light situations. The sensitivity performance has been extended from the visible light range to include near infrared range to support images at night, which is often essential for surveillance camera use.

Key features include the following:
• 3 Megapixel resolution giving greater detail and image quality without compromising on price
• Remote set-up lenses making the security installer’s job to gain crystal clear focus much simpler
• Alarms and audio allows easy integration of the cameras with remotely monitored systems
• SD card slots allow edge recording as a back-up to end users’ NVRs
• IR illumination guarantees “excellent performance” day and night

Vista product manager Bob Forehand stated: “This new range from Vista is an evolution of our popular E-Series, but brings significantly more functionality, image performance and low light capability at the same competitive price. The new Sony Starvis technology is an excellent addition to the range, producing high quality detail in 3 Megapixel resolution for end users.”

Samsung Techwin increases flexibility of iPolis Mobile app

The iPolis Mobile for Android and Apple iOS devices has been upgraded and can now support playback directly from SD cards inserted within Samsung Techwin cameras.

The added flexibility offered by this enhancement to the iPolis Mobile app is likely to be of particular interest to those end users who wish to remotely retrieve recorded video of specific incidents captured by a small number of cameras installed in their working environment as it negates the need for a DVR or NVR to record and store the video.

The Samsung Techwin iPolis Mobile app is now available for end users

The free iPolis Mobile app can be downloaded from the Android Play store and iTunes and can be set up in less than a minute, after which users are able to view streamed video from their selected camera via a wireless or 3G network.

Key features include auto detection for adding new devices and ‘Event’ search to provide easy access to recorded video.
