Benefits of multi-streaming

January 8, 2019

Multi-streaming (sometimes called “dual streaming”) refers to a camera streaming multiple independent video streams to the video management software (VMS) or network video recorder (NVR). Each stream has different settings, which may include any combination of frame rate, image quality and codecs.

Using multiple streams enables organizations to choose optimal video quality settings based on different use cases. For example, introducing a lower quality video stream can increase scalability and efficiency by reducing CPU and storage requirements.

This article explains the basic concepts behind multi-streaming, when you should use it, and how it can maximize your investment in video processing, network, and storage hardware.

Protecting unmanned, remote sites 

October 2, 2018

Unmanned, remote sites, especially those containing critical infrastructure assets, are easy targets for remote electrical substationintruders. Regardless of the intruder’s motivation – theft, terrorism, vandalism, or general mischief – facility owners need effective security solutions that meet operational and budgetary requirements. At the same time, the system must minimize nuisance alarms as repeatedly deploying response forces or maintenance technicians to remote sites rapidly triggers a distrust of the system. 

This post looks at how operators can use best-in-class security products while addressing the specific difficulties posed by remote and geographically distributed sites. 

Deterrence That Works 

Effective deterrence systems are the first step in protecting remote sites and their assets. Avoiding intrusions in the first place is always the ideal outcome, especially when security response may involve considerable time and cost. Consider the following deterrence options: 

  • Security fence – A well-maintained security fence, at least 7 ft tall and topped with barbed/razor outriggers, will deter the curious. However, keep in mind that a fence by itself isn’t effective against determined intruders as they can cut, lift, or climb the fence fabric in seconds. 
  • Visible signage and surveillance cameras – Clearly visible signs and surveillance cameras, indicating that the site is monitored 24/7 will, like fencing, help to dissuade casual intruders. But determined intruders may still remain undeterred, often planning ahead to conceal potential identifiers like faces or vehicles. Most importantly, cameras by themselves only record events, and do not stop them. 
  • Intelligent security lighting – Intelligent security lighting systems like the Senstar LM100 Hybrid Perimeter Intrusion Detection and Lighting System function as highly effective deterrence. First, targeted illumination along the fence line prevents intruders from hiding in the cover of darkness while enhancing the assessment value of camera surveillance systems. Second, instant-on illumination and strobing at the detected intrusion location acts as a strong psychological deterrent, letting would-be intruders know they are detected, their location is known, and they are being watched.  

Detect Intruders Before They Get In 

Detection at the perimeter is the next line of defense. Early detection leads to a faster assessment and response. There are many detection technologies on the market. For remote sites, the detection system must be reliable, cost-effective, integrated with on-site assessment devices, and above all, avoid the generation of repeated nuisance alarms.  

Fence-mounted sensors 

Modern fence-mounted sensors like Senstar’s FlexZone, FiberPatrol, Wireless Gate Sensor, and the Senstar LM100 are extremely effective, field-proven and easy-to-deploy. By analyzing the vibrations on the fence (and rejecting those generated by environmental forces like wind), the systems can detect and locate intruders with a precision of under 3 m (10 ft). In addition to generating alarms at off-site monitoring centers, the systems can be used for camera call-up and to control on-site devices like sirens or security lights. 

Coaxial-based sensors are generally highly economical and easy to deploy while fiber optic sensors require zero electronics on the perimeter and may be more cost-effective for larger facilities. 

Video analytics 

Videos analytics are a cost-effective means to augment security by leveraging the site’s existing surveillance Intruder caught on video at fencelineinfrastructure:  

  • Outdoor people and vehicle tracking analytics – Can be used to implement virtual zones and tripwires that track individuals and vehicles both near and inside the perimeter. Unlike simple motion detection, these analytics are designed to reject background vegetation movement and shadows. Early detection outside the perimeter can be used to direct PTZ cameras or switch to higher resolution recording, so that if the fence-mounted sensors detect an intrusion, high quality video is instantly available. The same analytics can also be used inside the perimeter to track the movement of people and vehicles once inside. 
  • Face and license plate recognition – Improves overall security management by automatically identifying maintenance personnel and automating the tracking of vehicles. When integrated with an access control system, these analytics can be used to unlock gates as well as place security zones under temporary access or mask. 

Obtain Situational Awareness 

High definition and thermal surveillance cameras, when directed by modern video management software, can provide excellent situational awareness. The Senstar Symphony VMS for example, includes many features to make monitoring remote sites easier: 

  • Effectively monitor hundreds of remote sites. Built-in video analytics reduces operator workload by automatically bringing attention to critical events.  
  • Use a single operator interface to view video, monitor the status of intrusion detection sensors, and control on-site devices like PTZ cameras, access controls, two-way intercoms, and loudspeakers. 
  • View the exact location of intrusion attempts on high-resolution maps. 
  • View live and recorded video from mobile devices, as well as automatically send images of captured video during alarm events via email/SMS to response forces. 

Deployment Considerations 

In addition to deterrence and assessment requirements, organizations need solutions that address day-to-day concerns involving nuisance alarms, reliability, and connectivity issues. 

Nuisance Alarms and Reliability 

Avoiding nuisance alarms generated by weather, animals, and lawful people is critical to remote site security. Too many nuisance alarms and security personnel may ignore valid alarms or hesitate to initiate a response until it is too late. Senstar designs its systems from the outset to minimize nuisance alarms: 

  • Ranging data from sensors is used to recognize and compensate for site-wide environmental disturbances like high winds or rain and to ensure that alarms are generated only from realistic intrusion attempts (e.g. a ball hitting the fence doesn’t trigger an alarm). 
  • Sensors are designed and tested for reliable operation in extreme environments (–40 to +70 °C/–40 to 158 °F). 
  • Maintenance staff can use the precision ranging to quickly find and resolve problematic areas (e.g. a loose fence sign). 
  • Video analytics reject background changes caused by vegetation movement and changes in lighting. 

Site Connectivity and Fallback 

Another concern is connectivity. Despite advances in communications, connectivity to remote sites can still be lost. It is critical that both intrusion detection and video recording remain operational after a loss of network connectivity. For on-site sensors, a device like the Senstar Rugged Controller can be used to provide local fallback functionality if network connectivity is lost. For video surveillance, edge storage (on-camera or on edge devices) can prevent the loss of critical video.

Cloud-based tools like the Senstar Enterprise Manager can ensure devices remain online, have the correct configuration, and automatically receive software and security updates.

Patented technology puts Senstar at the forefront of pipeline leak detection

September 25, 2018

Senstar’s recently announced FiberPatrol FP7000 pipeline integrity monitoring system for leak detection and third-party interference (TPI) for both gas and liquid-carrying pipelines, detects small leaks faster than any other system on the market.

Developed by Senstar’s fiber optic experts, the FP7000s patented technology combines Distributed Differential Temperature Sensing (DDTS) and Distributed Acoustic Sensing (DAS), allowing for the detection and location of small leaks faster and more accurately than traditional flow and pressure-monitoring solutions or other fiber-based solutions. In addition, TPI detection helps to avoid leaks in the first place by detecting digging or tampering before a damage can occur. FP7000’s DDTS technology can continuously monitor temperature (from a reference temperature) along the entire length of the sensor and can detect changes in temperature and temperature rate as low as 0.0005 oC and 0.001 oC/min, respectively. In addition, FP7000’s DAS technology detects minute acoustic signals emanating from a leak. The extreme sensitivity of DDTS and integration of both DDTS and DAS in one system enable the FP7000 to detect small leaks faster than any other leak detection system, while simultaneously rejecting environmental factors caused by weather or nuisance sources.

The FP7000 joins Senstar’s growing FiberPatrol family that includes fence-mounted intrusion detection, buried intrusion detection, TPI detection for pipelines and now leak detection for pipelines. The addition of leak detection to Senstar’s product portfolio of perimeter intrusion detection and video management solutions allows Senstar to provide end-to-end security of above and below-ground pipeline assets.
