Dynamically changing background ("dynamic background") still presents a great challenge to many motion-based video surveillance systems. In the context of event detection, it is a major source of false alarms. There is a strong need from the security industry either to detect and suppress these false alarms, or dampen the effects of background changes, so as to increase the sensitivity to meaningful events of interest. In this paper, we restrict our focus to one of the most common causes of dynamic background changes: that of swaying tree branches and their shadows under windy conditions. Considering the ultimate goal in a video analytics pipeline, we formulate a new dynamic background detection problem as a signal processing alternative to the previously described but unreliable computer vision-based approaches. Within this new framework, we directly reduce the number of false alarms by testing if the detected events are due to characteristic background motions. In addition, we introduce a new dataset suitable for the evaluation of dynamic background detection. It consists of real-world events detected by a commercial surveillance system from two static surveillance cameras. The research question we address is whether dynamic background can be detected reliably and efficiently using simple motion features and in the presence of similar but meaningful events such as loitering. Inspired by the tree aerodynamics theory, we propose a novel method named local variation persistence (LVP), that captures the key characteristics of swaying motions. The method is posed as a convex optimization problem whose variable is the local variation. We derive a computationally efficient algorithm for solving the optimization problem, the solution of which is then used to form a powerful detection statistic. On our newly collected dataset, we demonstrate that the proposed LVP achieves excellent detection results and outperforms the best alternative adapted from existing art in the dynamic background literature.

CCTV is widely acknowledged to be ubiquitous in British urban areas. However, despite its proliferation, there remains no concrete and certifi able evidence to suggest that it is the panacea to the myriad problems it has been introduced to tackle. The expansion of CCTV has continued unperturbed by the tentative, contradictory, and even negative evaluation fi ndings it has often produced. Despite the reservations about the quality and methodological soundness of studies by those involved in its evaluation, and the inconsistency of results that were considered to be competently and professionally conducted, consecutive governments have continued to celebrate its supposed effectiveness. This article critiques the evaluation doctrine that has dominated CCTV evaluations and outlines how it has resulted in an approach that overlooks the qualitative impact of CCTV, ignores the possibility that individuals other than offenders may be affected by the camera ' s gaze; and presumes that the only signifi cant impact of CCTV (and thereby worthy of evaluating) is on crime rates. The approach that has historically been taken to evaluate CCTV is just as important and illuminating as the inconclusive-ness of the evaluations themselves. This article will outline why the fi ndings from these evaluations are inconsistent, inconclusive and ultimately irrelevant.

CCTV is widely acknowledged to be ubiquitous in British urban areas. It is therefore not surprising that its use has seeped into institutions such as the school. As such it is important, perhaps more than ever, to be able to attribute an inherent value to privacy and demonstrate that its infringement facilitated by the burgeoning of technological surveillance practices could have potentially serious consequences for society. Drawing upon empirical research conducted in three secondary schools in the United Kingdom, this paper examines the value of privacy as perceived by pupils and the extent to which this is undermined or eradicated by the presence of CCTV cameras.s ore_1930 381..405

Modern surveillance devices are increasingly being taken off private networks and placed onto networks connected via gateway to the Internet or into Wi-Fi based local area wireless networks (LAWN). The devices are also increasingly using IPv4 and IPv6 network stacks and some form of embedded processing or compute built in. Additionally, some specialist devices are using assistive technologies such as GPS or A-GPS. This paper explored the issues with use of the technologies in a networked environment, both wireless and internetworked. Analysis of these systems shows that the use of IP based CCTV systems carries greater risk than traditional CCTV systems, primarily due to the exposure to IP based vulnerabilities. Furthermore, Wi-Fi based IP CCTV systems are additionally susceptible to remote, physical denial of service attacks due to the broadcast nature of wireless communication systems. Interception of traffic is possible with IP based systems, and again, Wi-Fi IP based CCTV systems...

Lirieka Meintjes-Van Der Cognitive bias affecting forensic
Walt & Adebola Olaborede expert opinion
The influence of bias in forensic expert opinion can create problems for
the criminal justice system. Many research studies have shown that forensic
experts can be susceptible to cognitive bias that influences their memory
and reasoning and affects the objectivity of their opinion and decisions.
This has contributed to the misidentifications and consequent wrongful
convictions of innocent persons. This article examines bias that can affect
the opinion offered by forensic experts in criminal trials and discusses
the risk of bias in some forensic science disciplines, such as fingerprint
examination, trace evidence, bullet comparison and DNA analysis. The
article contends that different factors such as the quality and/or clarity of the
forensic evidence, contextual case information and subjective interpretation
of forensic analysis can exacerbate bias. Strategies recommended for
mitigating bias include blind testing, blind verification, independent review,
linear sequential unmasking (LSU) and the filler control method. The merits
and demerits of these strategies are highlighted. The article also proposes
certain cross-examination questions that could expose bias in forensic
examination.

This empirical study examines the role of educational technologies in connecting male and female university campuses in Saudi Arabia. In order to do so, it addresses the research question: What are the outcomes, ramifications and implications of the ways in which educational technologies have been employed to reconfigure social relations between male and female campuses in Saudi Arabia? This question is answered by a naturalistic study of a state university in the Eastern Province of Saudi Arabia, based on analysis of interviews, observations and documents. From an analysis of the data following the guidelines of the grounded theory technique, two themes emerged: (a) the influence of social relations on the way educational technologies are developed and used, so as to sustain certain aspects of the social structure; (b) the reciprocal influence of the technologies so developed and used on other aspects of the social structure. Considering both themes leads to a theoretical proposition that educational technologies might be introduced to preserve particular components of the social configuration, although once introduced, these technologies might impinge in return upon other components of the social configuration.

Bu yazıda, bir suç olayının aydınlatılmasında akla gelen ilk delil olan; parkta, sokakta, meydanda veya metroda, yani hayatın her alanında gördüğümüz MOBESE kameralarıyla yürütülen kameralı gözetleme faaliyetinin mevcut haliyle hukuka aykırı olduğu iddia edilmektedir. Bu iddia üç adımda gerekçelendirilmektedir: (1) MOBESE kameralarıyla; kişiler kamuya açık alanlarda izlemekte, kaydedilmekte ve bu kayıtlar saklanmaktadır. Bu izleme-kaydetme-saklama süreci; kişisel verilerinin korunması hakkına, özel hayatın gizliliğinin korunması hakkına ve kişilerin maddi ve manevi varlıklarını geliştirme hakkına müdahale teşkil etmektedir. (2) Kamusal alanda kullanılıyor olmaları kameraları hukuka uygun yapmaya yetmez. Bu müdahalenin hukuka uygun olabilmesi için diğer şartlarla birlikte sürecin kanunla düzenlenmesi gerekir. (3) Ülkemizde MOBESE olarak bilinen kamusal alanda kullanılan kameralı gözetleme faaliyetinin esaslarını düzenleyen bir kanun yoktur. Hâl böyleyken, bu yazıda kameraların kurulum amaçlarına da uygun olarak suçun önlenmesinde elverişli, uygun ve etkili olduğu bilimsel olarak ispatlanmış mekânlarda, tedbirin süresine uyularak, izleme-kaydetme-muhafaza etme ve kullanma sürecini açık, belirli ve denetlenebilir kılan özel bir kanuni düzenlemeihtiyacına dikkat çekilerek, yapılacak kanuni düzenlemede dikkat edilmesi gereken hususlar maddeler halinde sunulmaktadır.

La presente investigación pretende aportar a los debates del campo de las políticas públicas de seguridad y los estudios de vigilancia, particularmente, los vinculados a la implementación de nuevas tecnologías de información y comunicación en el marco de los modelos de “ciudad inteligente”. Con esta tarea, se realiza una evaluación sobre cómo el Gobierno Nacional de la República Argentina y el Gobierno de la Ciudad Autónoma de Buenos Aires implementaron sus políticas de videovigilancia policial en la Capital Federal entre los años 2010 y 2015, período durante el cual se desarrolló un conflictivo proceso de descentralización de las funciones de seguridad de la órbita federal a la autonómica, que dejó como resultado una superposición de idénticas políticas de Estado, entre las que se destacó la instalación simultánea y redundante de dos Circuitos Cerrados de TV en el mismo espacio urbano. Utilizando el análisis estratégico históricamente situado como marco analítico para este estudio de caso, se traza el objetivo de analizar la matriz política desde la cual los actores estatales desarrollaron sus estrategias de poder y utilizaron estas políticas para disputar, con recursos y capacidades diferenciales, la redefinición de las fronteras territoriales de la capacidad estatal de coacción sobre el espacio público de la ciudad, así como el poder de representación simbólica sobre el tópico de la seguridad. La hipótesis que sostiene este trabajo es que el conflicto entre el Gobierno Nacional y el Gobierno de la Ciudad Autónoma de Buenos Aires, hicieron que las políticas de videovigilancia implementadas volvieran contingente, no sólo el resguardo del derecho a la privacidad, sino también el fortalecimiento del derecho a la seguridad, en una relación de suma variable.

Perkembangan teknologi dimulai dengan beralihnya revolusi industri mekanik ke digital dimana semua peralatan dengan mesin mekanik otomatis secara bertahap beralih fungsi. Manusia mengalami revolusi informasi sebagai perubahan yang dihasilkan oleh teknologi informasi dari dua bentuk terknologi ,komunikasi manusia untuk menyalurkan informasi dari sistem computer modern untuk memprosesnya, dipengaruhi oleh dua factor yang mengarahkan refolusi informasi. Yaitu perkebangan yang cepat serta penyebaran informasi yang luas dan peningkatan pentingnya pengetahuan dalam produksi kekayaan serta penurunan relative dari nilai sumber-sumber material. Howard Frederick menyatakan bahwa laju pertumbuhan dan akumulasi pengetahuan era informasi meningkat sangat cepat eksponensial. Sebagai perbandingan andaikata informasi di dunia pada tahun 1 jumlahnya disamakan dengan satu unit, maka penggandaan (doubling) pertama memakan waktu 1500 tahun, yang kedua 250 tahun, dan selanjutnya pada awal abad 20 menjadi 150 tahun. Sementara itu, Jacques Valee memperkirakan penggandaan tersebut berlangsung setiap 18 tahun, dan James Martin menyatakan penggandaan tersebut turun 5 tahun sekali pada 1970an dan pada tahun 2000an menjadi tiga tahun sekali. Menurut Alvin Toffler, manusia sekarang ini telah memasuki era yang disebutnya the third wave (gelombang ketiga). Era ini biasa juga disebut era industrialisasi atau era informasi. Secara umum, terdapat beberapa sumber utama revolusi teknologi yaitu: Penemuan mesin cetak pertama oleh Johanness Gutenberg pada tahun 1455, merupakan sebuah revolusi teknologi pertama manusia dalam hal penyebaran informasi ke banyak kalangan dengan cepat setelah ditemukannya kertas. Penemuan telepon pada tahun 1876, oleh Alexander Graham Bell yang kemudian mempatenkannya dengan biaya $ 100.000. Skala penggunaan teknologi ini berkembang dari tahun ke tahun dengan pesat. Ditemukannya radio siaran. Jaringan radio siaran mulai berkembang sejak tahun 1920 kemudian teknologi televisi pada tahun 1926, dan bermunculan TV komersil pada tahun 1947 yang menyiarkan berbagai fenomena menarik dunia seperti peristiwa pemakaman John F Kennedy, dan pembunuhan Lady Di, Perang di Kosovo dan sebagainya. Pada akhir PD II, penduduk yang memiliki televisi baru berkisar 8000 rumah di seluruh dunia. Namun memasuki abad 20, dua pertiga rumah yang ada di seluruh dunia telah memiliki pesawat televisi. Penemuan Komputer pada tahun 1946. Sesungguhnya revolusi di bidang computer ini dapat dibagai dalam tiga tahap, yaitu pada tahun 1943, dengan percobaan pertama oleh Thomas Watson penemu IBM. Pada tahun 1967, IBM dipatenkan dengan biaya $ 167.500. kemudian pada tahun 1977, Ken Olsen pimpinan dan pendiri perusahaan digital menyatakan bahwa tidak ada alasan untuk setiap individu memiliki satu computer di setiap rumah mereka. Perkembangan selanjutnya dari computer ini adalah eksprimen dari Departemen Pertahanan US yaitu Advanced Research Projects Agency (ARPA), yang kemudian menghasilkan jaringan dunia melalui internet (ARPANET). i Seiring dengan berkembang dan majunya teknologi di dunia untuk menunjang suatu kebaikan, sebuah perkembangan juga terlihat kentara mulai banyak disalah gunakan untuk kejahatan. Diantaranya ada beberapa kasus di Indonesia yang belum terungkap seperti misteri pembunuhan yang menewaskan Tri Ari Yani Puspa Ningrum alias Arum, tak kunjung terkuak. Mahasiswi Universitas Esa Unggul itu ditemukan tewas di dalam kamar kos, Jalan H. Asmat Ujung, Kompleks Kebon Jeruk, Jakarta Barat, 9 Januari 2017 ii. Di Jakarta saja tersebut ada dua titik di kawasan Jakarta Utara yang disebut rawan penjambretan iii. Tak sedikit diantaranya wilayah jalan-jalan raya sepi yang rawan begal saat malam. Kawasan Venue Asian Games juga rawan, seorang karyawan swasta menjadi korban kejahatan di jalan trotoar depan pusat pembelanjaan Senayan City, Tanah Abang, Jakarta Pusat pada rabu (18/7) malam dengan total kerugian

Interception of traffic is possible with IP based systems, and again, Wi-Fi IP based CCTV systems are more susceptible due to protocol vulnerabilities and lack of processing power. The paper concludes that more research is needed in this area to identify and classify generic vulnerabilities that these systems are vulnerable to, and to present a framework which can be used to mitigate the risk of adopting these systems.

The aim of this essay is to bring up the idea of a two-way surveillance realm from a top-down hierarchical standpoint (governments, politicians, economic systems and their will to search for crime, terrorism and their prevention) to a bottom-up hierarchy in which regular people agree with this surveillance methods and moreover they want to watch the others. The first part approaches the concept of panopticism in Closed-Circuit Television (CCTV) in London while the second part will focus on new ways of surveillance through new technologies in our daily lives.

Nowadays automated detection and recognition of human beings and their actions in surveillance
videos is gaining importance. The paper presented is divided into different segments which include methods of
extraction of images of different moving objects from surveillance videos, identification and face and action
recognition. The smart surveillance system proposes information processing techniques for CCTV based
surveillance systems. It gives information about the advanced surveillance cameras having the property of
identifying and providing real time notification. This paper is a study on the methods and applications of the human
action recognition through surveillance system. It can be most effectively used in surveillance of crowded public
places, finding missing and suspicious people and recognizing their actions, human computer interaction and
automated refereeing.

This paper explores closed-circuit television (CCTV) and its 'bright promise stage,' as it was contemplated, marketed, and implemented as a low-cost classroom tool. After the Federal Communications Commission issued the 1952 Sixth Report and Order, many schools and communities sought to bring educational television to the classroom. However, this model was financially out of reach for most. Closed-circuit television was a more affordable version of educational television that could cater to specific classroom needs. CCTV represents just one of many new technologies that have been promoted as ideal for classroom instruction over the last century. Using articles and advertisements from popular press magazines, educational journals, books, and archival materials, this paper seeks to illuminate the 'social practices and conflicts' that contributed to the conversations around CCTV's classroom utility and its eventual shift away from this capacity. It concludes by connecting CCTV's promotion in the 1950s to more recent new media technologies.

The world is moving towards automation in every field, which is the main motivational reason of recent researches. Automated CCTV surveillance systems have also drawn the attention of researchers since the last decade. In CCTV systems, data is collected from multiple sources with overlapping contents, which is mostly redundant and containing both informative and useless contents. Therefore, there is a need of effective data collection for which image prioritization methods can be used. Another major issue in CCTV surveillance systems is secure data dissemination to ensure the authenticity of important data for correct decision making. This paper presents an overview of different multimedia data security techniques such as image hashing, image encryption, image steganography and watermarking for data dissemination. Finally, we present our recommendations about combining multiple techniques together in a sequence to develop a more secure channel for data dissemination in CCTV surveillance systems.

In after show interviews, reality television stars often cite the camera and producorial manipulation, like editing, when trying to explain away their conceivably indefensible behavior. And much academic criticism of reality shows hinges on these very same “negative” features of the format: technological mediation, truthiness, their “lack” of reality. However, given the pervasiveness of 21st Century digital communication technology, and our decades worth of exposure to the regulating gaze of CCTV cameras, this rhetorical position is increasingly losing merit, despite its continued deployment—at the start of 2013, A&E’s Storage Wars was met by denouncements of a similar flavor. This paper attempts to draw on technology’s current place in the cultural milieu to challenge, at the very least, the theoretical position that might find reality TV external to our lived reality. Some specific reality TV personalities, ones who have denounced or commented on their on-screen selves, are examined in order to open up a conversation worried less about the contrivance of reality TV and more about the contrivance of contemporary living. MTV’s Jersey Shore, Teen Mom, The Hills, and ABC’s The Bachelor are some of the televisual texts sampled for the content of this paper.

Perekam Video Digital (DVR) dan Jaringan Perekam Video (Nvrs), dan implikasi buat system desainer dan konsumen akhir. Mula-mula datang camera dan monitor, diikuti oleh Video Cassette Recorder (VCR), merekam satu video streaming ke tape 3 jam di 25/30 frame per detik dan tidak jarang dipicu oleh piranti input (tombol serangan di bank, contohnya). Technologi selanjutnya mengambil kita multiplexer, yang mengizinkan sekian banyak aliran video yang bakal direkam ke pita yang sama dan dipisahkan jadi diskrit, sanggup diliat replay dan time-lapse VCR yang mengizinkan menjatuhkan frame dan dengan demikian diizinkan 3 jam tape difungsikan selagi masa lebih lama, meski terhadap budget berita yang hilang. DVR Pesatnya perkembangan algoritma kompresi video (MJPEG, MPEG-4, H.264 dll), kecepatan pemrosesan komputer dan pengurangan langsung dalam budget daya simpan data selanjutnya memunculkan DVR. Ini Kamu akan pertimbangkan yang merupakan fungsi dari Multiplexer bersama-sama dengan disk computer buat daya simpan di ruang tape, seluruhnya disimpan di kotak yang sama bersama-sama dengan sekian banyak port penambahan buat konektivitas. DVR pengganti kombinasi multiplexer + VCR dan memberikan non-linear akses ke materi direkam rata-rata dipilih oleh camera ID, waktu dan tanggal. Konsistensi mutu bahan direkam dapat dengan cara umum lebih tinggi dari yang diperoleh dengan pita analog meski mutu aktual yang diraih bisa saja atau tidak kemungkinan lebih baik, tergantung terhadap algoritma kompresi dan konfigurasi individu. Dengan Cara umum lebih tidak sedikit pilihan diprogram buat parameter video yang masing-masing rekaman stream,(resolusi gambar, jumlah frame per detik Opsi memicu, sejak mulai / berakhir dll), namun DVR cuma bermanfaat di mana camera analog berada seluruh kabel kembali ke ruangan DVR. DVR Kompeten saat ini mempunyai CAT 5 port jaringan maka piranti akan disediakan bersama alamat IP dan dengan demikian jadi mampu diakses lewat jaringan Ethernet.

Public street surveillance – a domain of Closed Circuit Television (CCTV) – has grown enormously and become common place in our society as an all-purpose security tool. Previous authors have raised concerns over social, civil and privacy issues; however, there has been limited research to quantify such concerns. Nevertheless these concerns not only define the social risk perception of CCTV, but may also cause its social relocation and alter social support of CCTV.

This book is essential reading for those interested in CCTV from a social, privacy or security aspect. There has never been such a publication that provided a definitive measure of the social issues of CCTV. The book is based on a study that applied a psychometric risk theory to a new public street CCTV surveillance system, measuring the social risk perception over a period of time. In addition, factors that may define and drive such social issues, social concerns with CCTV control and CCTV gender issues are discussed in-depth. The book demonstrates that CCTV may not have yet found its true social risk measure and that current social support may not necessarily be defined or robust.

COVID-19 pandemic caused by novel coronavirus is continuously spreading until now all over the world. The impact of COVID-19 has been fallen on almost all sectors of development. The healthcare system is going through a crisis. Many precautionary measures have been taken to reduce the spread of this disease where wearing a mask is one of them. In this Project, we propose a system that restrict the growth of COVID-19 by finding out people who are not wearing any facial mask in a smart city network where all the public places are monitored with Closed-Circuit Television (CCTV) cameras. While a person without a mask is detected, the corresponding authority is informed through the city network. A Machine learning architecture is trained on a dataset that consists of images of people with and without masks collected from various sources. The trained architecture achieved 98.7% accuracy on distinguishing people with and without a facial mask for previously unseen test data.

Argentina, al igual que otros países, determinó que los barbijos son "de uso social obligatorio", una medida lógica desde el punto de vista sanitario que causa y causará dificultades en la seguridad y la aplicación de la ley: todas las personas transitan con su cara oculta, enmascarada, de día o de noche. ¿Qué implicancias tiene? Cualquier acto delictivo quedará impune a menos que se capture in-fraganti al autor. Fuera de esto, la mayoría de los delitos quedarán impunes y los delincuentes pudiendo transitar libremente sin riesgos. Lic. Juan Moratto Consultor en Seguridad Perito Judicial TSJ-Neuquén Introducción La Pandemia desatada por el SARS-COVID-19 tiene implicancias sobre el 100% de las actividades humanas, sus consecuencias sociales globales aún son inconmensurables. En este sentido, los ciudadanos demandan más que nunca una infraestructura de seguridad que les garantice la paz social, la asistencia del sistema sanitario nacional, el acceso a los bienes de consumo, a los recursos financieros y a las actividades laborales. Sin embargo, existe un talón de aquiles oculto en la infraestructura de seguridad, pública y privada, un factor "X" que no fue contemplado hasta el momento: la identificación humana durante y posterior a una pandemia o, lo que es lo mismo, la reingeniería forzosa de dicho mecanismo producto del COVID. El factor "X" es ese pequeño trozo de tela protectora que se coloca en el rostro: el barbijo. Como elementos de protección adicionales opcionales pueden agregarse los anteojos protectores y los guantes de látex.

The need to estimate a particular quantile of a distribution is an important problem which frequently arises in many computer vision and signal processing applications.  For example, our work was motivated by the requirements of many semi-automatic surveillance analytics systems which detect abnormalities in close-circuit television (CCTV) footage using statistical models of low-level motion features. In this paper we specifically address the problem of estimating the running quantile of a data stream when the memory for storing observations is limited. We make several major contributions: (i) we highlight the limitations of approaches previously described in the literature which make them unsuitable for non-stationary streams, (ii) we describe a novel principle for the utilization of the available storage space, (iii) we introduce two novel algorithms which exploit the proposed principle in different ways, and (iv) we present a comprehensive evaluation and analysis of the proposed algorithms and the existing methods in the literature on both synthetic data sets and three large real-world streams acquired in the course of operation of an existing commercial surveillance system. Our findings convincingly demonstrate that both of the proposed methods are highly successful and vastly outperform the existing alternatives.  We show that the better of the two algorithms (data-aligned histogram) exhibits far superior performance in comparison with the previously described methods, achieving more than 10 times lower estimate errors on real-world data, even when its available working memory is an order of magnitude smaller.
