01. CCTV in the sky: police plan to use military-style spy drones:

Arms manufacturer BAE Systems developing national strategy with consortium of government agencies

Police in the UK are planning to use unmanned spy drones, controversially deployed in Afghanistan, for the ­"routine" monitoring of antisocial motorists, ­protesters, agricultural thieves and fly-tippers, in a significant expansion of covert state surveillance.

The arms manufacturer BAE Systems, which produces a range of unmanned aerial vehicles (UAVs) for war zones, is adapting the military-style planes for a consortium of government agencies led by Kent police.

Documents from the South Coast Partnership, a Home Office-backed project in which Kent police and others are developing a national drone plan with BAE, have been obtained by the Guardian under the Freedom of Information Act.

They reveal the partnership intends to begin using the drones in time for the 2012 Olympics. They also indicate that police claims that the technology will be used for maritime surveillance fall well short of their intended use – which could span a range of police activity – and that officers have talked about selling the surveillance data to private companies. A prototype drone equipped with high-powered cameras and sensors is set to take to the skies for test flights later this year.

The Civil Aviation Authority, which regulates UK airspace, has been told by BAE and Kent police that civilian UAVs would "greatly extend" the government's surveillance capacity and "revolutionise policing". The CAA is currently reluctant to license UAVs in normal airspace because of the risk of collisions with other aircraft, but adequate "sense and avoid" systems for drones are only a few years away.

Five other police forces have signed up to the scheme, which is considered a pilot preceding the countrywide adoption of the technology for "surveillance, monitoring and evidence gathering". The partnership's stated mission is to introduce drones "into the routine work of the police, border authorities and other government agencies" across the UK.

Concerned about the slow pace of progress of licensing issues, Kent police's assistant chief constable, Allyn Thomas, wrote to the CAA last March arguing that military drones would be useful "in the policing of major events, whether they be protests or the ­Olympics". He said interest in their use in the UK had "developed after the terrorist attack in Mumbai".

Stressing that he was not seeking to interfere with the regulatory process, Thomas pointed out that there was "rather more urgency in the work since Mumbai and we have a clear deadline of the 2012 Olympics".


 

BAE drones are programmed to take off and land on their own, stay airborne for up to 15 hours and reach heights of 20,000ft, making them invisible from the ground.

Far more sophisticated than the remote-controlled rotor-blade robots that hover 50-metres above the ground – which police already use – BAE UAVs are programmed to undertake specific operations. They can, for example, deviate from a routine flightpath after encountering suspicious ­activity on the ground, or undertake numerous reconnaissance tasks simultaneously.

The surveillance data is fed back to control rooms via monitoring equipment such as high-definition cameras, radar devices and infrared sensors.

Previously, Kent police has said the drone scheme was intended for use over the English Channel to monitor shipping and detect immigrants crossing from France. However, the documents suggest the maritime focus was, at least in part, a public relations strategy designed to minimise civil liberty concerns.

"There is potential for these [maritime] uses to be projected as a 'good news' story to the public rather than more 'big brother'," a minute from the one of the earliest meetings, in July 2007, states.

Behind closed doors, the scope for UAVs has expanded significantly. Working with various policing organisations as well as the Serious and Organised Crime Agency, the Maritime and Fisheries Agency, HM Revenue and Customs and the UK Border Agency, BAE and Kent police have drawn up wider lists of potential uses.

One document lists "[detecting] theft from cash machines, preventing theft of tractors and monitoring antisocial driving" as future tasks for police drones, while another states the aircraft could be used for road and railway monitoring, search and rescue, event security and covert urban surveillance.

Under a section entitled "Other routine tasks (Local Councils) – surveillance", another document states the drones could be used to combat "fly-posting, fly-tipping, abandoned vehicles, abnormal loads, waste management".

Senior officers have conceded there will be "large capital costs" involved in buying the drones, but argue this will be shared by various government agencies. They also say unmanned aircraft are no more intrusive than CCTV cameras and far cheaper to run than helicopters.

Partnership officials have said the UAVs could raise revenue from private companies. At one strategy meeting it was proposed the aircraft could undertake commercial work during spare time to offset some of the running costs.

There are two models of BAE drone under consideration, neither of which has been licensed to fly in non-segregated airspace by the CAA. The Herti (High Endurance Rapid Technology Insertion) is a five-metre long aircraft that the Ministry of Defence deployed in Afghanistan for tests in 2007 and 2009.

CAA officials are sceptical that any Herti-type drone manufacturer can develop the technology to make them airworthy for the UK before 2015 at the earliest. However the South Coast Partnership has set its sights on another BAE prototype drone, the GA22 airship, developed by Lindstrand Technologies which would be subject to different regulations. BAE and Kent police believe the 22-metre long airship could be certified for civilian use by 2012.

Military drones have been used extensively by the US to assist reconnaissance and airstrikes in Afghanistan and Iraq.

But their use in war zones has been blamed for high civilian death tolls.

Surveillance Systems that Support Unlimited Remote Viewing Users

Posted by Mike Haldas on March 13th, 2012

At CCTV Camera Pros, it is common to receive phone calls from customers who are looking for a surveillance DVR or security camera that will support an unlimited number of remote users. These users are typically researching security camera systems for applications such as a day care that wants to allow parents to login and check on their children. For this type of application, multiple users need to be able to login to the system remotely at the same time to view cameras from the Internet. Most of the time customers that are researching these solutions have the unrealistic expectation that network-able DVRs and IP cameras can handle an unlimited number of simultaneous remote viewers. This article will discuss the hardware, software, and bandwidth constraints that make it impossible for any video surveillance system to handle an unlimited number of remote users. The variables discussed in this article apply to surveillance DVRs and security cameras (both IP and analog).

Bandwidth Limits

The first technology that limits the number of viewers supported by a camera system is Internet bandwidth. At the location where your DVR or camera is located, you need a high speed Internet connection to support remote viewing. Typically businesses use cable, DSL, or a T1 for their Internet connection. Ask your service provider what the maximum upload speed is for your Internet connection or run a speed test from a PC at the location. The upload speed is the one you want to note.

Software Limits

The second technology that limits the number of remote users supported is the software of the DVR or IP camera software. Network DVRs and IP cameras both use embedded web server software to serve video streams to client applications, web browsers, and mobile apps. Just as a web server used to host web sites is limited in the number of users that can access a web page, the web servers built into surveillance equipment limited by the number of video streams it can serve simultaneously. Users need to also consider that the software of your DVR is also performing other resource intense operations such as recording video and managing all of the configurations rules related to recording and alarms.

Hardware Limits

Last, there is the limitation of the hardware. Even the fastest supercomputers available have limits to the number of processes they can handle at any given time. Most entry and mid-level surveillance DVRs use processors equivalent to the Atom processor, like the ones use in tiny netbook computers. And again, these processors need to handle a lot of important tasks such as continuously recording multiple video streams, activating recording based on alarm events like motion detection, and allowing users to playback and export recorded video. It is easy to see why these devices are limited in the number of remote users and video streams they can serve.

Max Remote Viewers for Surveillance DVRs

When shopping for a surveillance system, keep in mind that not all DVRs and IP cameras are created equal. Higher end DVRs have faster processors and more memory. In addition, some manufacturers build better software than others. Below are a few stand alone (embedded) DVRs and PC based DVRs with varying numbers of simultaneous remote viewer support. Please note that some manufacturers limit the number of total users that can be logged in and others limit the total number of video streams that can be served.
