cameras (CCTV and FDAS)

Factors to consider while choosing CCTV Cameras

lens, sensor, output resolution, structure of cctv cameras

Lens

the smaller the size in mm, the wider the area you will be able to see

Fixed lenses, Varifocal lenses

2 Types of Lenses

Fixed lenses

often used indoors because they provide a general view of the area

Varifocal lenses

often used outdoors because zoom and focus can be adjusted (within a range) to capture specific details

CMOS and CDD

main types of sensors used in CCTV

output resolution

the higher the MP, the better the resolution of the camera

Structure of CCTV Cameras

ideal type of camera to use will largely depend on the purpose and the environment of your application

Analog cameras

uses an image sensor to capture video

Analog cameras

costs less

Analog cameras

DVR is easier to set up and understand; installation is a bit more straightforward

Analog cameras

recorded video files tend to be smaller; more difficult to hack

IP/Network cameras

use internet protocol technology to transmit video data over the ethernet network

IP/Network cameras

typically required network infrastructure such as switches, routers, and network

IP/Network cameras

Wi-Fi cameras are also a kind of ___________

IP/Network cameras

higher resolution, better image quality, remote access and analytics, and scalability

IP/Network cameras disadvantages

complication during set-up; high cost; high bandwidth requirements; higher storage requirements

IP/Network cameras

designed for easy live streaming over the internet

Analog cameras

require additional hardware components to translate their electronic signals into digital for transmission over the internet

Closed-circuit television cameras (CCTV)

integral components of surveillance systems used in various settings; serves the purpose of monitoring and recording activities in their vicinity

bullet camera

c-mount camera

day/night camera

dome camera

hidden camera

panoramic camera

pan tilt camera

thermal camera

vandal proof camera

Pan tilt camera

possible to pan, tilt, and zoom; can manually control or program this to follow an accurate view of things; best suited for large areas that require active monitoring

Panoramic camera

provide an efficient way of monitoring large areas and can help reduce potential blind spots; low maintenance as they have no moving part

C-mount camera

can use detachable lenses to suit different purposes; if you need surveillance beyond distance, this camera with a particular lens can achieve that purpose

Varifocal lens

often used to fine-tune focal distance and angle of view; can be zoomed in and out without losing focus

Hidden camera

designed to be discreet and inconspicious; typically compact and lightweight making them easy to conceal

Hidden camera

offers feature such as: motion detection, night vision, and remote viewing capabilities

Vandal proof camera

designed to withstand intentional or accidental damage form vandalism/tampering; built with robust and durable materials; designed to withstand harsh environmental conditions and physical assaults

Vandal proof camera

include features such as infrared night vision and wide dynamic range for clear imaging in challenging lighting conditions

Dome camera

designed to withstand all elements both inside and outside; allows camera to work even in low-light or no-light settings due to built-in infrared LEDs

Vandal resistant, weatherproof, sleek design, high resolution, discreet positioning, monitor at a wide angles, night vision

main benefits of dome camera

Bullet camera

named for their distinct cylindrical shape

Long-range vision; easy installation

advantages of bullet camera

Day/night camera

capable of operation in both normal and poorly lit environment; benefit from not requiring inbuilt infrared illuminators as they can capture clear video and images thanks to their extra sensitive imaging chips

Thermal cameras

use infrared technology to capture images based on the heat emitted by objects rather than visible light; effective in lowlight and challenging weather conditions

Thermal cameras

widely used in areas where standard cameras may not perform well (complete darkness, fog, areas with harsh weather conditions)
