Be An Expert And Consultant On CCTV Within A Day.....by Destined Boy by destindd(m): 7:08pm On Nov 26, 2018
Good day everyone, Am gonna be enlighten you on how you can be a CCTV specialist and consultant within a day.
Well, let me say am a funny, easygoing person, single(smiles) and a focus person. What am going teach you, you can't get it somewhere else even though u paid for it, because 95percent of CCTV consultant and engineers in Nigeria don't knw mostly of wat am going to say here. It is a privilege for you to be part of this segment, so stay tune and enjoy.
WHAT IS CCTV?
CCTV is known as closed circuit television but we mostly called it a video surveillance because is no longer a closed circuit.
CCTV is refer to as technology behind in capturing an image from a video source and transmitting it through some type of transmission media(coaxial cable or Ethernet cable) to the receiving unit(DVR).
PURPOSE for CCTV
The main reason why we need to install a CCTV camera is to monitor activities, security purposes and for evidence.
WHAT ARE BENEFIT OF CCTV?
Deter crime
Monitor scenarios and activities
Gather Evidence
Arrive at the Right Decisions
Maintain Records
Our major concern here is on security but am gonna say a brief things on some purposes, so that you can well be enlightened on how CCTV works.
PURPOSES
Educational Purpose
Business Purpose
Media Purpose
Research Purpose
Military purpose
Legal purpose
Healthcare purpose
Security Purpose.
I will lay more emphasis on security but let's begin with Educational purpose.
Educational Purpose: Have you ever wondered how manage can i view an online class without b
eing there, this is actually the work of a CCTV camera.
Lesson can be recorded for review and training purposes. PTZ cameras are majorly used because they offer distance learning.
Research Purposes: We do watch documentaries, do u think someone is in the jungle recording and monitoring the activities of all these wildlife animals?.No, they only install a CCTV camera to monitor the activities of the wildlife animals and all the activities are being recorded for later review.For examples there is a waterproof cameras install beneath the sea for the monitoring of sharks,whales e.t.c.
Military Purpose: Is because our lovely country *Nigeria* is actually lacking technology. The issue of Boko Haram should have been resolved by now, instead of sending our soldiers to the terrain they haven't been before, why can't they install a vandalproof cameras to those areas so that they can easily monitor the activities of Boko Haram before sending our soldiers down there. It is a pity because our dearly soldiers are being killed day by day. �
our aim is on Security Purpose.,
SECURITY PURPOSE
Video surveillance function...
Monitoring
Detection
Recognition
Identification
MONITORING
Monitoring is all about do you want to see a scene and know if something is happening?...it takes 10percent of the screen.
Detection
Do you want to see an event and determine exactly what is happening?...it takes 25 to 35percent of the screen.
Recognition
Do you want to find out what exactly is happening behind the scene?.... it takes 60percent of the screen.
Identification
Do you want to see the individual and determine exactly who is involved?....it takes 120percent of the screen.
Lets go ahead to type of cameras, if you ask most engineers and consultants what are the type of cameras we have they will say Dome, bullet e.t.c while some we say indoor and outdoor cameras. But am here to enlighten you on the type of cameras so let's go.
TYPE OF CAMERAS(Based on technology)
Analog camera
IP camera
Wireles
Analog camera is divided into two part
Traditional/conventional analog cameras
HD(high definition) analog cameras
Traditional cameras
This cameras measure resolution by the number of horizontal lines called TVL(television linese). A higher the number of lines in an image means better resolution. But now technology has mostly shifted from TVL to pixels, that makes traditional analog less demanding because it doesn't give a sharp and quality footage.
Analog cameras
It is capable of capturing high definition video surveillance footage up to 1080p resolution....it is measure in pixel.They can record surveillance video in 720p, 1080p high definition(HD).
HD camera has different standard, incase you wanna buy a HD analog CCTV camera make sure they have these three standards.
AHD: Analog High Definition
TVI: Transport video interface
CVI: Composite video interface.
IP cameras
IP is known as internet protocol, IPv4 is currently the most used internet protocol now....IP cameras is of two types
Non POE/Normal cameras
POE enabled IP cameras
POE means power over Ethernet .
The image quality, sharpness is much greater than conventional analog CCTV cameras, and better than HD analog CCTV cameras.
Wireless Cameras
wireless security cameras are closed circuit television cameras that transmit a video and audio signal to a wireless receiver through a radio band....As a consultant you don't have to recommend this type of cameras to your client because hackers can easily hack d cameras which may lead to serious security issues.
Type of Cameras(based on shape)
Dome Camera
Bullet Camera
Box Camera
PTZ Camera
Dome Camera: Dome Cameras is a half spherical shaped cameras... They give a wide coverage of an area, it can be vandal resistant, and indoor and outdoor options are available.
This type of cameras are mostly used for indoor security systems. Some dome cameras are design with infrared illuminators enable them to capture videos in low conditions....
As a consultant you know that due to its wide coverage capability, they are majorly installed in Retail stores and offices where wide coverage is needed.
Bullet cameras
They are long and typered cylinder cameras. They are mostly used outdoors, especially area where long viewing is necessary..
We can use bullet cameras indoors where the long viewing is required like backyards and parking spots.
Incase your client ask you that he/she wanna install a camera where wide viewing is needed please don't recommend bullet cameras because it is for long viewing not wide viewing.
Box cameras
Box cameras are comprised of the camera body and lens.
For indoor use : a mount bracket is required for installation.
For outdoor use: a housing is required.
I wont be making emphasis on C and C mount cameras. am sorry
We mostly used this cameras at the receptionist area, because we can actually adjust the focus and the angle of view. They can be zoomed without in or out without losing focus.
PTZ camera
PTZ means PAN/TILT/ZOOM. PTZ cameras can pan(move left and right), tilt(move up and down) and zoom in or out, PTZ can rotate 360degrees to view an object directly below dem....indoor and outdoor options are available.
When installing a PTZ camera make sure you also a fixed camera with it...why because in a case you wanna view an event going on at that moment, you will only focus the camera at that particular place to know what exactly is going on leaving other areas unchecked, that's why you should also install a fixed camera wit it.
PTZ offers distance learning, it is used in sport, that's why it's easy for a referee to go back and look at the recorded footage of the scene so that he can make the right decision.
All these are CCTV technology.
I will continue later, isnt easy..
Tired kindof...Am sorry for the inconvenience.
You can contact me if you definitely want to go real deep on CCTV and some computer configuration that can fetch you money aside CCTV.

Thank You in anticipation.
God bless you all.

Hi, i am looking to buy a 2 camera cctv kit with the HDD of between 250gb to 500gb. There are some limitations due to lack of constant electricity at the property where i intend to install the cctv, do you think there is an option to this for example are there effective solar powered cctv or buying the usual cctv and supporting it with a UPS or Inverter.

I look forward to reading from you.

@comeandcollect
you don't really need to go solar CCTV camera, now lite cannot power your camera with UPS because UPS doesn't last longer.
You can definitely power it with your inverter because it needs a 24hrs power supply.
you can go for inverter.
Thank you

Ok, is it an integrated inverter with the camera or separate inverter. Any idea of distributors for this product, thanks.
