How to Choose your Video Surveillance System?

Selecting a new video surveillance system can be confusing among so many options.

Do all 1080P cameras look the same? Do megapixels tell us the image quality?

Now I had the opportunity to convince a friend to upgrade from a 1080P (2 Megapixel) system to a 1080P (Also 2 Megapixel) system.

My friend’s first question was, How does 1080P in another brand look better?
Here I replied “If this were so, The Lord of The Rings would have recorded it with a Galaxy S7! It also supports 1080P!”

Falling into the game of quantity of Megapixels = greater image quality can point us in the wrong direction and make a misinformed decision that will be a wrong decision.

The camera we used to update their system was a DS-2CD2123G0-IS (HIKVISION 2 Megapixel Series 2 PRO Dome, See HIKVISON Series 2).

This camera has the same resolution as the previous model (2 Megapixel), but being the HIKVISION Series 2 it delivers much better performance in low light, greater detail in backlight conditions or difficult lighting (reflection, shadows) and accurate colors. .

This line also has the advantage of having analytics, these allow to avoid false alarms (we will talk about that later …), and also a superior compression (H.265 + that allows dramatically greater detail and much less hard disk space and reduction bandwidth (seamless extreme video in Hik-Connect App)

Here are the results:

Greater performance in difficult lighting conditions
Camera HIKVISION 2 Series 1080P 2 Megapixel vs Camera “N” 1080P 2 Megapixel

Improved performance in low light environment
Camera HIKVISION 2 Series 1080P 2 Megapixel vs Camera “N” 1080P 2 Megapixel

This is a very interesting example… Well, many cameras “on paper” look comparable, the features may even appear similar, but at the time of an “event” is when one notices the difference.

Many manufacturers have focused on promoting “Megapixel”, leaving out features that are critical in real applications where you can have detail in any lighting situation.

Having evidence in high detail after a serious event is one of the greatest tools, it can help us to greatly reduce costs, avoid losses, help public safety and be certain of everything that happened.

SAY GOODBYE TO FALSE ALARMS, Analyze Evidence in Seconds

Motion detection on commercial equipment is a “headache” (on your old equipment), one simply cannot check every time a moving branch, a shift in illumination, or the slightest shadow trigger a motion detector.

Professional devices integrate analytics, these allow us to have real alerts: When detecting a person, someone entering an area, someone crossing from one point to another.

HIKVISION’s Professional line makes these analytical events simple to track, see the image below:

The equipment interface allows the professional installer to make a precise adjustment and only have alerts when required.

The HIKVISION Professional Line allows selecting or customizing alert events using advanced algorithms and artificial intelligence.

“Nobody likes to search for a person or event within days of recording, with Hikvision’s analytics, this search can be done in seconds.”

In the example above, a zone was selected for Intrusion events. This means we will only have an alert when an object enters this zone.

Installation, Wiring, and Professional Programming

A good product with the most advanced technology is only part of our project.
HIKVISION equipment is installed by professionals, ensuring that it has the highest image quality and longer useful life.

A professional installation allows you to have a system “ready for the future”, which can be expanded or upgraded to new technologies in the coming years.

Integrate an Intrusion Detection System (Alarm)

Now that we have the best video surveillance system, now that we understand that megapixels do not mean “image quality”, what’s next?

The HIKVISION alarms systems allow

The HIKVISION alarm systems can be managed in the same Hik-Connect App, this allows us to “Arm” the entire system from our smartphone.

What is the advantage? Intrusion sensors allow us to detect intruders in any area (wireless), without being activated by rain / wind / light and send an alert to a siren, smartphone, and professional alarm monitoring centers (Call Public Safety).

Remote programming with Hik-PROConnect

Hik-PROConnect is an application used by professionals that allow advanced equipment programming, monitoring health status, and administration.

Both images were taken in low light conditions

Do megapixels equal greater image quality?
Do the same megapixel values mean that camera image quality is the same?
Do greater megapixel values always mean better image quality?

The short answer is no, no, and no.

A camera can be of lower resolution and still provide greater detail, it is important to consider the following additional points.

The previous experiments were carried out with the lighting conditions and the camera indicated for such application (low light sensitivity, backlight performance…)

Backlight Performance

Currently, most cameras have WDR, however, this does not work the same in all.

The quality and effectiveness of WDR depend on the brand and model of equipment and the profit specified by the manufacturer (Of course, on paper, everything looks the same… it is always better to perform a test!)

WDR allows you to have detail in a scene with different types of lighting

The image below shows 2 WDR cameras but yields different results:

IR Performance

The IR illumination already featured in most cameras can allow us to capture in conditions with zero illumination.

However, the performance is not the same in all cameras:

Case: IR overexposure

IR causes overexposure on license plates, that is why it is recommended to use cameras without IR and high sensitivity at low light:

Low Light Sensitivity

The following example shows 2 cameras with IR, similar characteristics.

We can see how the low light performance is different in the following images:

The example below shows 2 cameras with IR, one with lower sensitivity in low light (same IR distance):

Why should I install IP Video Surveillance? Lower Costs?

6 out of each 10 installed systems nowadays use IP technology and the tendency is to finish this 2021 with 8 out of each 10 systems.

Increases in the price of raw materials have raised the installation costs more than ever and correcting a detail in an installation is unaffordable.

Why are all video surveillance systems migrating to IP?

There is NO IMAGE NOISE in cameras, in IP the signal is digital

The IP camera signal is digital, this prevents its image quality from degrading due to distance, wiring, electrical noise, low-quality transceivers, or noise caused by the power source.

The signal of an IP camera can travel up to 300 M in twisted pair cable (Cat5e, Cat6), several kilometers through fiber optics or wireless links without affecting its image quality.

No distance limit!

The IP systems can be used to cover areas from a few meters away to hundreds of kilometers, ensuring the highest image quality.

Fewer Points of Possible Failure

Analog systems require additional external power supplies, transceivers (Baluns), and connectors, where poor installation can make maintenance a nightmare and create a poor user experience.

IP systems do not require external power sources and all connections use RJ45 or fiber optic connectors, clear cabling standards, and “future proof” (Ready to implement new technologies).

Future Proof

The networks of companies, businesses, and homes demand Gigabit, but in a few years 10Gb will be the standard, so the technology will follow.

An analog system cannot be updated, it is necessary to change all the equipment and even throw the wiring away (Different standard, coaxial cables, Cat6 is not enough…)

An installation with IP devices allows the user to update their equipment by reusing the same infrastructure, do not risk having to throw everything away.

Greater Image Quality

The best manufacturers use the best sensors, lens, and processing algorithms in their IP product lines such as HIKVISION PRO Series, WiseNET, and IDIS.

For this, we must all be clear that “Megapixels do not Equal Image Quality”, Megapixels only tell us the number of pixels.

Lower Cost of Installation and Maintenance

It is no secret that the cost of copper continues to rise and that it is increasingly difficult to cross additional cables in companies (full ceiling, full pipes).

IP Systems can all travel on the same Cat5e, Cat6, Cat7, or fiber optic cable, allowing for cleaner, fail-safe installations, ready for new technologies and expandable without reaching the moment of “There is no space for a single cable the tube.”
