Abid, good question.
The marketing claim is that surveillance specific monitors are more durable / reliable / longer lasting, built to run 24/7 for years, unlike commercial ones.
I do not know enough here to have an meaningful opinion. Let's see what everyone say.
Samsung manufactures both and yet I can't find any differenciator given by them. I can throw a marketing pitch to sell something. What I need is either a white paper to back it up or actual solid facts as to why one should invest in a surveillance LED. Especially since the technical specifications do not highlight anything noteworthy to justify the price difference.
Also, Pakistan does not have any standards imposed on monitoring. Is there any standard internationally for what type of monitors should be used for surveillance?
Two things many surveillance monitors have are real glass front panels and metal housings. Also, most surveillance monitors with analog inputs have BNC connectors and looping inputs.
I have a strong suspicion that Samsung uses similar or identical panels as their regular commercial monitors. Their regular 22' monitor has the same resolution, reposnse time, brightness, viewing angle, and contrast ratio as the SMT-2232. The SMT-2232 has BNC connectors, a higher quality cabinet, a glass panel, lower operating temps, and speakers.
Is that worth an extra $350 per unit?
Thank you for your valuable input. Is there any feature in surveillance monitors that has less strain on the eyes ?
One advantage of surveillance monitors is often the ability to configure and lock-out various inputs so that the user can't plug their own DVD player or XBox or other equipment into the display on the night shift.
Abid, I don't see anything in the spec sheet that would help to reduce eye strain any more than a consumer panel. Usually a matte panel in lieu of glossy would be ideal.
Since Pelco was stated directly in the OP, and I manage Pelco's monitor line, allow me to shed some light here.
The principle difference between a Consumer Electronics monitor and a Security monitor is average daily use. Consumer Electronics monitors are designed to run 4-6 hours a day, whereas Security monitors are designed to run 24 hours a day. That design includes power supplies designed to run 24/7, backlighting designed to run 24/7 and other components that have higher tolerances than what you might find in a CE equivalent.
For those of you who might scoff at this simple definition, I harken you back to the early days of hard-drive based security DVRs, because the situation is similar. Back in 2004-2005, we saw those hard drives fail a lot because they simply were not designed for 24/7 use. In fact I had one big name HDD manufacturer tell us back in the day that CE hard drives were only meant to spin 2-3 hours a day, whereas security DVR HDDs were spinning 24/7. They had to specifically design a new breed of drive controller and other components to support 24/7 use. A similar reality exists for security monitors today.
But yes, as somebody pointed out, warranty is also a factor. Most CE monitors carry a 90-day warranty, or some offer a warranty as high as one year. Most security monitors carry a 3-year warranty.
Are the higher tolerance components and the better warranties (and the better customer service support) worth the premium price? Many of our customers tell us the answer to that is 'yes', but I'll also admit the price compression in the CE space is applying pressure in the security space when it comes to monitors.
Many of the other factors cited in the other comments (input types, cooling capability, etc.) are real as well, but I also know that Security manufacturers optimize their scalers and other tuning controls around security video inputs as opposed to broadcast inputs. I even know one manufacturer that does a sort of digital WDR correction on their security monitors. The point is, there are actual, real physical differentiators in security monitors over CE monitors that make them more expensive to build and thus higher price to the customer.
I can't speak to professional grade monitors thoroughly, but I have some experience with broadcast grade monitors (used in newsrooms and production studios) and generally they have the same 24/7 requirements that security monitors have.
Ironically, broadcast grade professional monitors are about 2X the price of Security monitors, but that customer base never complains about the price.
just make sure you purchase monitor with external power supply. i have never seen any monitors fail any parts except power supply. if it had an internal one we had to send it to repair, if it had external we bought a new power adapter for buttons and replaced it on site.
even consumer grade monitors working in 24/7 work without any failure except their power supply.
