Is In Depth Learning Of CCTV Necessary?

Generally, industry people know significantly less about CCTV / video surveillance than they think they know. I attribute this to 2 factors:

- There is no formal education coming into the industry so everyone is forced to pick it up on their own, so the variation in core knowledge is immense (most just get a smattering of on-the-job experience and vendor sales presentations).

- The technology does significantly change, so the in-depth learning you might have had in 2008 about CCD imagers and coaxial cable (e.g.) is not only less relevant but can lead you to make wrong decisions in 2018. Related Beware Out of Date Knowledge

As for how in-depth one should go that depends on one's role and one's ambition. Someone wanting to design and manage enterprise systems definitely would benefit far more from in-depth learning than an installer for residential systems.

I believe one who learn of CCTV in depth and keeps him/her self updated with latest technologies in this industry stands a better chance to remain part of the family or else one risks changing a career.

When the system is operational, principles and concepts appear to be irrelevant but, if things are not right that is when "know how"  is appreciated.

In the nutshell in depth learning tells how CCTV works and experience that CCTV works.

Fabian is right on the money here - and his wise words are applicable to any industry.

i.e. your own approach to knowledge is largely dictated by your perception of your current position.

"This is my job" people don't perceive the value of in-depth knowledge - because they can (and will) jump to another industry for $2 more per hour.

"This is my career" people understand the value of in-depth knowledge - because it absolutely helps them further their own career. 

I Believe learning id depth of CCTV is necessary but could not matter in real time setup; ive dealt with clients who doesn't need or care about the in depth and that most of the issues were solved on spot - most of us sometimes exceeded the information we have..... but it is sometimes necessary once for a while, its important to keep your info checked and updated because it could be handy specially in hard spots situations. And you should know when to make use of the info you have.
