4. Dome Cameras (Analog& IP)
Dome cameras are either ceiling mounted or suspended
from a wall mounted bracket
depending on the application and the field of view
required. The camera unit is mounted
inside a transparent dome which can be tinted to obscure
the camera position.
Dome cameras come in a wide variety of forms. A home
security camera usually can see in
a range between 0 to 70 feet depending on the resolution,
sensor and lens it's using.
Dome security cameras are packed with infrared LED lights to work perfectly with little or
no light at all, such as the Reo link RLC-422 dome IP camera, which can see up to 100ft in
total darkness with 24pcs infrared LEDs Take-away info to make quick decisions: Place the
camera above the front door and off-street windows (at about 9 feet above the ground)
to cover the most vulnerable areas around your home and avoid potential vandalism.
The dome camera is one most commonly used for indoor and outdoor security and
surveillance. The shape of the camera makes it difficult for onlookers to tell which way the
camera is facing, which is a strong piece of design, deterring criminals by creating an air of
uncertainty.

5. Bullet Cameras (Analog& IP)
bullet camera. By Vangie Beal A type of video camera often used
in surveillance systems, named because of its shape and size.
Bullet cameras are small (2 to 2.5 inches long) and are limited
to a fixed focal length lens. ... Bullet cameras are also called
lipstick cameras.
The Dahua is considered tops in its class but there are a few contenders out there that
come very close to possibly dethroning the Dahua DS-2CD2032. It is hard to beat the
little bullet for quality performance it is easily one of the most reliable bullet cameras on
the market.
Bullet cameras usually mounted to the side of the wall and it’s point to surveillance areas
look like the barrel of a gun or a bullet. Bullet cameras with weatherproof design. they are
installed outdoor applications, they are with large size and can provide the best way to
deter theft. Majority of bullet cameras come with mounting bracket, The mounting bracket
can make bullet camera with flexibility to swivel horizontally and vertically for getting best
field of view. Camera can be large size, and equipped with big lens for long range view
distance, also can be added with Infrared illuminators for long range night vision.

6. Box Camera (Analog & IP)
The cameras provide excellent low light sensitivity
along with very good wide dynamic range (WDR). You
can select from a wide range of lenses, environmental
enclosures, and mounting brackets Possibilities include
variable lenses, megapixel lenses, IR-type lens, and
auto-iris lenses.
Lenses do not come standard with Dahua box cameras. In order to ensure you get the right
lens, it’s best to discuss all available choices with us. Possibilities include variable lenses,
megapixel lenses, IR-type lens, and auto-iris lenses.
Highly visible so acts as a deterrent
Resistant to dirt in challenging environments
Provides surveillance over long distances
Casing also protects against glare and rain

7. Turret Camera (Analog & IP)
A turret camera, also known as a mini dome, eyeball or
flat-faced dome camera, has a ball-and-socket type of
design. It is like a sliced sphere, which can be easily
swiveled around in its "socket" once the base has been
mounted.
The night vision used in turret security cameras usually
includes 2 types: infrared (IR) and EXIR night vision.
The turret is an armored structure supporting one or more guns -- typically a heavy cannon
and a couple of machine guns. ... Turning the traverse gear rotates the turret on the hull,
allowing the tank crew to aim the main gun without turning the entire tank. The crew can
also pivot the main gun up and down.
 Easy angle adjustment after installation
 Insect-proof
 No IR bounce
 Can be installed both vertically and horizontally.
 Less intrusive than PTZ & bullet cameras
 Lack of vandal proof
 Larger than dome type

8. PTZ Cameras (Analog& IP)
A pan–tilt–zoom camera (PTZ camera) is a camera that is capable
of remote directional and zoom control. In television production,
PTZ controls are used with professional video cameras in television
studios, sporting events, and other spaces. They are commonly
referred to as robos, an abbreviation of robotic camera.
These high-performance PTZ systems include not only a very long-range
optical camera system but also a thermal imaging camera for operation
in total darkness. The optional synchronized laser illuminator can be
selected for ranges from 500 M to 5000 M allowing you to see at night
over 3 miles away.
A Preset Position is a user-defined location where the camera can be pointed, zoomed-in,
and focused. Preset positions can be defined and labeled if the camera supports this.
Configure these functions using the Presets/Tours tab
A PTZ camera (pan-tilt-zoom camera) is a speed dome camera that is capable of remote
directional and zoom control. PTZ security cameras can pan left and right, tilt up and down,
and zoom in and out. The PTZ dome cameras are usually larger in size for outdoor uses
with super high resolution.

9. Fish Eye Cameras (Analog& IP)
The fisheye camera is a single camera which allows you to record
everything with a 360 degree panoramic view. The strength of
this camera can reduce the quantity of cameras needed to cover
the same surveillance area.
A fisheye lens is an ultra wide-angle lens that produces strong visual
distortion intended to create a wide panoramic or hemispherical image
The angle of view of a fisheye lens is usually between 100 and 180
degrees while the focal lengths depend on the film format they are
designed for.
A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to
create a wide panoramic or hemispherical image. ... The angle of view of a fisheye lens is
usually between 100 and 180 degrees while the focal lengths depend on the film format they are
designed for.
To achieve the “fisheye effect” you would need a lens with a focal length of between 8 or
10mm.Here's a general guideline: If you're shooting with a full frame camera like the Canon 5D
Mark II or Nikon D700, you need a lens with a focal length of between 15 or 16mm

10. What is DVR:-
A CCTV digital video recorder (or “DVR” for short) is
essentially a computer that
saves security video images to a hard drive. Most
security cameras in use today
capture an analog picture. The DVR converts the
analog signal to digital and
then compresses it. ... DVRs generally come with 4, 8,
16, or 32 camera inputs.
What is NVR:-
A Network Video Recorder (NVR) is a digital device
which sits on your IP CCTV network to receive live
image/video streams and record them digitally to a hard disk.
A network video recorder (NVR) is a specialized computer
system that includes a software program that records video in
a digital format to a disk drive, USB flash drive, SD memory
card or other mass storage device. An NVR contains no
dedicated video capture hardware.
