These are real pages from the book. The table of contents is the full one: 8 parts and 60 topics.
You're standing under a pole with two lenses in your hand, and the customer asks why 6 mm and not 2.8. You know which one works. Explaining why is another story.
The manual covers focal length in three paragraphs of angles, sensor formats and formulas. Nothing on the page looks like what you see from the ladder.
Here, focal length is one drawing: 2.8, 4, 6 and 12 mm, all from the same pole, each with its scene width marked. Double the mm, half the width.
Pixels per foot, the PoE budget, storage for 30 days, subnets and the commissioning order work the same way: each one has its own page.
You see it, you get it, and you do the math without going back to the manual.
How the system fits together, cameras, lenses, pixel density, networks and PoE, bandwidth and storage, cabling and code, and commissioning: 64 pages, all illustrated.
Think of it this way:
The customer wants to identify faces across a 20-foot-wide front entrance. Your supervisor asks which camera, and the exam can ask the same thing with different numbers.
You open the pixels-per-foot page and it's drawn: 1920 pixels across 20 feet of scene, 96 PPF, with the four DORI levels marked right next to it.
Same with the lens formula, the PoE budget, storage math, VLANs and commissioning: each one on its own page.
Video Security Systems Illustrated is 8 parts and 60 topics, all drawn, and it closes with the four calculations on one page and the most frequent mistakes on the exam and the job.
What you see drawn, you don't have to memorize.
The video chain from lens to screen, analog vs. HD-over-coax vs. IP, DVR, NVR and VMS, recording options, the site survey, operational requirements and security drawing symbols.
Bullet, dome, turret and PTZ, multisensor and fisheye, sensor size, resolution, lux ratings, WDR at the backlit door, IR cut filter and IR range, shutter speed.
Focal length in one drawing, fixed vs. varifocal vs. motorized, angle vs. field of view, the lens formula in four steps, scene width, iris and depth of field, IR shift.
Pixels per foot, the four DORI levels drawn, from PPF back to scene width, the camera pick in five steps, license plates, mounting height and worked examples.
IP addresses and subnets, switch ports and uplinks, VLANs, PoE standards and watts, the PoE budget in four steps, heaters, 328 feet and beyond, injectors and safe remote access.
H.264, H.265 and smart codecs, CBR vs. VBR, frame rate, bandwidth math in three steps, storage math in five steps, motion recording, retention days and RAID.
Cat5e, Cat6, Cat6A and coax, T568A and T568B, testing, Class 2 circuits and the NEC, PoE bundles and heat, grounding and surge, mounting, privacy and signage.
Commissioning in the same order, time sync, day and night checks, as-builts and handover, troubleshooting by the chain, the four calculations on one page and the most frequent mistakes.
At the end of the book: The four calculations on one page and a review of the most frequent mistakes on the exam and the job.
Practice the way the exam asks: lens, pixel-density, PoE and storage questions, each with the answer worked out step by step so you can see where you went wrong.
Each common mistake drawn twice, wrong and right (backlit cameras, blown PoE budgets, washed-out IR, leaky mounts), so you can catch it on paper before it costs you a callback.
