For example, a system which correctly detects when tested three times has detected at a rate of 100%, but might not have a \"probability of detection\" of 100%. \"P/sub d/\" is often misused to describe this experimental result as a 100% probability of detection. \"Confidence limits\" for P/sub d/ can be estimated and minimum extents for testing can then be demanded. These confidence limits are sometimes calculated using the normal, or the chi-squared, statistical distributions. Using these distributions for PIDS testing is questionable because they are often used outside their region of validity. There are fundamental constraints which obstruct conventional statistical confidence limits for P/sub d/ from being found. P/sub d/ statistics are discussed and an exact way to express detection uncertainty using the binomial distribution is described. Ways to reduce testing, yet maintain confidence, are discussed. Experts are concerned that extensive, but unrepresentative, testing gives an unwarranted impression of reliability. This paper emphasises the importance of representative testing and the clear presentation of results.","PeriodicalId":376576,"journal":{"name":"Proceedings The Institute of Electrical and Electronics Engineers. 29th Annual 1995 International Carnahan Conference on Security Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132392650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experience shows that this is largely ineffective, both as a detector and a deterrent. However, modern digital imaging systems can solve both these problems by maintaining constant vigilance 24 hours a day. These systems can be versatile and can operate in several different modes, video motion detection, video nonmotion detection and incident capture, thus providing a flexibility of application environment. By basing these systems on powerful PC technology the end user benefits from a large range of facilities at relatively low cost. In particular, it is possible to have low cost frame storage and high performance communications over telephones, ISDN or Ethernet. Image sequences both prior to and after an event can be stored and transmitted. Archiving and retrieval of events can be done efficiently through standard databases. However, in order that such systems be operationally viable it is essential that the detection algorithms be smart enough to reduce the number of false alarms to virtually zero. Most of the discussion concerns technology that is currently available and in everyday use: the author uses the ASTRAGUARD product as a specific example of such a system.","PeriodicalId":376576,"journal":{"name":"Proceedings The Institute of Electrical and Electronics Engineers. 29th Annual 1995 International Carnahan Conference on Security Technology","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134446440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
