Moreover, it\u2019s probably safe to say that the main usage of CCTVs right now is for security reasons.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Used for monitoring your assets to surveying activities, just the presence of CCTV cameras in your area could highly reduce the chances of security incidents happening.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Even more, if any security incidents still ended up happening, footage captured from your CCTV cameras could be used to help find the cause of it and used as evidence for criminal activities.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As technology developed, variations of CCTV cameras available in the market (such as Dome, Turret, or PTZ cameras just to mention a few) increased. Each with its own advantages and disadvantages, and price ranges.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">With that many choices that come with varying prices you might be asking \u201cWhich CCTV cameras could secure my assets optimally?\u201d.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A very good question that you need to ask prior to setting up your CCTV camera. Because at the end of the day, CCTV is an investment you make to help you secure anything that you want to secure.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The last thing you wanted to do is make an investment in a CCTV camera and then ask questions such as, \u201cWhy does my CCTV camera didn\u2019t work as I thought it would?\u201d or \u201cWhy does the image look blurry?\u201d.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Well, one thing that you should remember is that a CCTV camera is still a device, and the optimal use of a device depends on the ability and the knowledge of the one using it.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">So, with CCTV cameras, one of the most important things you need to understand is the DORI.\u00a0<\/span><\/p>\n<p><b>What is DORI?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">In the \u201cdictionary\u201d of CCTV cameras, DORI stands for:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b><i>D<\/i><\/b><i><span style=\"font-weight: 400;\">etection<\/span><\/i><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b><i>O<\/i><\/b><i><span style=\"font-weight: 400;\">bservation<\/span><\/i><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b><i>R<\/i><\/b><i><span style=\"font-weight: 400;\">ecognition<\/span><\/i><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b><i>I<\/i><\/b><i><span style=\"font-weight: 400;\">dentify<\/span><\/i><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">It is a standard (IEC EN62676-4: 2015) given by the International Electrotechnical Commission or IEC to determine the ability of CCTV camera lenses in capturing images by using PPM (Pixels Per Meter) as the unit of measurement.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Higher PPM number means a clearer image captured by the CCTV camera, and the distance that a camera could achieve a certain PPM number depends on the capacity of its lens.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This ability of capturing images at a certain PPM number determines if an object could be detected, observed, recognized, and identified.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Then, what\u2019s the difference between detection, observation, recognition, and identification and what\u2019s the standard PPM numbers given for each of those levels?<\/span><\/p>\n<p><b>The DORI Level Explained<\/b><\/p>\n<p><span style=\"font-weight: 400;\">It\u2019s easier to explain the different levels in the DORI by using an example.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Below is the DORI specification of a <\/span><b>6 MP<\/b><span style=\"font-weight: 400;\"> CCTV camera that has two choices of lenses (<\/span><b>2.8 mm <\/b><span style=\"font-weight: 400;\">lens and <\/span><b>4 mm<\/b><span style=\"font-weight: 400;\"> lens).\u00a0<\/span><\/p>\n<p><b>Detection (25 PPM)<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The detection level is where the CCTV operator will be able to detect the existence of a person or vehicle.
