October Camera CourseAuthor: Brian Rhodes, Published on Sep 07, 2017
Learn video surveillance and get certified.
IPVM provides live online classes, recorded videos, personal help, cutting edge education and certification.
We have substantially rewritten the course and training materials for 2017 to reflect new developments in resolution, H.265, HD analog, image quality, video analytics and camera cost.
What the IPVM Camera Course Covers
In 12 sessions, 5 of which have been completely redone for 2017, we teach surveillance cameras extensively, using our industry leading 292 page 2017 Surveillance Camera Book and custom class presentations for:
(1) Lens Fundamentals
The course starts with the fundamentals - lens length, FoV/AoV, varifocal vs fixed focal and focusing - to make sure everyone understands how to use, calculate and plan coverage area.
(2) Lighting Fundamentals
Lighting and its variances are key to security cameras. Starting from lux levels and using lux meters, we explain how shutter and iris controls adjust to lighting levels, what F-numbers are and how understanding F-numbers can help in evaluating lens / cameras.
(3) Low Light
Building on low light, we dig into the factors impacting low light performance, a key differentiator among security cameras. We explain IR illumination, super lower light image processing, larger size imager formats and thermal, comparing them and analyzing the tradeoffs of each. Finally, we spend special attention on tradeoffs and issues among integrated IR cameras, the most common option today.
(4) Image Quality
Resolution and compression are often lumped together but they are different things. We explain different resolution options (including 720p vs 1080p vs 4MP vs 5MP vs 4K vs 12MP and 4:3 vs 16:9 aspect ratios). We then contrast to compression levels, looking at quantization scales and the tradeoffs between camera settings of higher and lower quantization that manufacturers typically never explain.
Covering codecs (H.265, H.264, MJPEG, etc.), streaming modes (MBR, VBR, CBR), smart codecs, we explain the tradeoffs between bandwidth, image quality and network impact.
(6) Smart CODECs / WDR / FPS
Building on streaming, we explain how smart codecs work, the different techniques used and how they so significantly reduce bandwidth consumption.
Then we teach the difference between 'true' and 'fake' WDR, analyze the role of WDR dB ratings and show the impact of frame rate increases (from 1fps through 120fps) across different scenes.
Reveals one of the biggest underappreciated and misunderstood elements of video surveillance, we break down the 8 key drivers of bandwidth variation, explaining how bandwidth can vary 10x or more across cameras, even with the same resolution and frame. We conclude by teaching the right and wrong ways to calculate bandwidth / storage.
We teach how to use PPF / PPM correctly, what mistakes to avoid and how to incorporate this to improve the quality of your designs. This is consistently one of toughest but most useful parts of the course in designing systems and laying out cameras.
(9) Form Factors
Covers IP vs AHD vs CVI vs TVI vs SDI plus domes, minidomes, boxes, bullets, PTZs, and cubes, plus IK and IP ratings, explaining the tradeoffs and key reasons for using one vs the other.
(10) Panoramic vs PTZs
Panoramics and PTZs are two of the most common choices for covering wide areas. With panoramics now reaching 10+ MP, and adding IR, we contrast when and where to use them vs HD speeddomes. Finally, we explain and contrast the differences between fisheye, panomorph and multi-imager panoramics.
(11) ONVIF / API & SDKs
Learn what API and SDKs are, going through practical examples of camera and VMS manufacturer's APIs. Plus, understand ONVIF S, G, C and Q profiles, breaking down the strengths and limitations of these offerings.
(12) Camera Selection
In our capstone session, we pull all of the training together, showing you how to select and use different camera technologies in common scenarios including parking lots, offices, hallways, entrances, license plates and more.
Who Should and Should NOT Take this Course
Even if you have lots of hands on experience with surveillance cameras and manufacturer training, you should take this course. It teaches cameras at much greater depth than what regular field work or product specific training provides.
However, if you have no experience with surveillance cameras, you should not take this course unless you can commit to spending 10 to 15 hours per week studying. We have had many people take this course without experience and do very well, but only if they dedicate sufficient time to studying. You cannot pass this course simply by reading a few hours the night before the exam.
The Camera course will meet live online, starting October 12th for 12 times over 6 weeks (Tuesday and Thursday for 1 hour from 1pm - 2pm ET (17:00 - 18:00 UTC).
All sessions are recorded and posted for viewing on-demand anytime the same day the session is held.
At the end of classes, you will take a comprehensive final exam including multiple choice and essay questions. If you pass, you will become IPMVU Camera certified (see list of IPVM Certified Professionals)
