WDR - Wide Dynamic Range

Wide Dynamic Range (WDR) technology helps to get detailed information from the dark part of

the image without saturation from the bright part. There is no limitation of zone area with the WDR

function and the color image is crisper than when using traditional BLC functions. It combines two

fields which are high shutter speed exposure in bright areas and low shutter speed exposure in

dark areas into one composite image.

BLC - Back Light Compensation

In CCTV applications it is common to have a bright light source behind the subject of interest. A

person at an ATM or entering through an outside door are common examples. Without

compensation, these subjects would normally appear as dark silhouettes. The aim of backlight

compensation technology is to allow the camera to find the best picture conditions and

automatically give the necessary light level compensation, so that users can obtain good

identification of a subject in the foreground when there is a bright light source in the background.

BLC works by enhancing specific zones in the picture which usually contains the subject of

interest. WDR is a more effective alternative to BLC that does not depend on the subject being in

a specific zone.

True Day and Night (TDN)

Day & Night refers to a function which helps the camera adapt to low lighting conditions. In low

light, it switches the camera from color to monochrome automatically, allowing for much greater

light sensitivity.

ICR (Infrared Cut filter Removal) The IR cut filter is on when the camera is operating as a color

camera for precise color reproduction. With ICR, the filter is removed which allows for much

greater light sensitivity in monochrome mode.

DSS - Digital Slow Shutter

Digital Slow Shutter (DSS) allows you to see clear images in extreme low light conditions without

the need for artificial illumination. DSS settings can be adjusted to enhance the low-light

performance of the camera. DSS settings slow the picture frame rate and increase the

camera’s sensitivity in low light conditions. Light sensitivity increases as the number of fields of

integration increase.

IP67, IP66

Cameras with IP67 and IP66 Certification meets the Ingress Protection Standards for dust and

moisture resistance, allowing the camera to be installed in environments subject to wind and

rain. Infinique’s outdoor cameras come with an IP protection rating of IP67 or IP66. The table

Auto Digital Flip

The convenient auto digital flip feature allows for easy monitoring when viewing objects that

pass directly below the camera. As the camera pans in the vertical direction to follow the

object, digital signal processing will automatically flip the image 180° top-to-bottom as the

object passes beneath the camera, so the image remains right-side-up for easier viewing.

CCD - Charged Coupled Device

Charged Coupled Device is a solid state semiconductor imaging device often referred to as an

integrated circuit, chip or "imager" solid state cameras are sometimes referred to as CCD

cameras.

Sensitivity

Sensitivity is a camera's ability to reproduce a given scene with a given amount of light,

expressed in footcandles or lux. The sensitivity of a camera is a measure of its performance in

low light conditions.

Signal to Noise (S/N) Ratio

Electronic noise is present to some extent in all video signals. Noise manifests itself as snow or

graininess over the whole picture on the monitor. The important factor that determines the

tolerance of noise is the amount of noise in the video signal, the signal to noise ratio (S/N).

Infinique’s cameras have a S/N ratio of 48dB and higher providing excellent picture quality.

40dB 100 Reasonable, fine grain or snow in the picture, some fine detail

lost

30 dB 32 Poor picture with a great deal of noise

20 dB 10 Unusable picture

Automatic White Balance

Accurate color reproduction requires that the camera compensate for the color temperature of

the light source. Automatic white balance is a feature that the camera uses to do color

compensation. For indoor applications incandescent, fluorescent, and quartz lighting all have

different color temperatures. Outdoors there is sunlight, mercury vapor, and low pressure sodium

lighting, all of which have drastically different color temperatures. In many applications the color

temperature can change as lighting conditions change. Privacy Masking

This function allows for areas in the picture to be masked so that they cannot be viewed or

recorded. The size and position of these masks are programmable. This feature is useful in

applications where a camera can see into areas that are not relevant to the security purposes

for the camera and the owner does not want to be subject to privacy invasion claims.

3D-DNR - Digital Noise Reduction

Infinique’s cameras are equipped with 3D Digital Noise Reduction and have effective 3D noise

filtering system which removes picture noise from the recorded video. These cameras give high

quality video in low light conditions and by reducing the noise, they use less digital bandwidth

and storage space compared to cameras without 3D-DNR.

OSD - On Screen Display

Cameras that support Online Screen Display have On Screen Menu setting. Cameras support

remote control OSD via RS-485 resulting in easy, quick, user-friendly setting from the monitoring

and control location.

3D-DNR Off 3D-DNR on



PoE - Power over Ethernet

Power over Ethernet is a standard that allows you to power the IP cameras via the same network

cable that will carry the video data back to the network. Unlike traditional CCTV cameras, PoE

enabled cameras doesn’t require a power supply at the site. Infinique’s IP Cameras supports

Power over Ethernet (PoE) 802.3af. PoE devices use a power classification in order to identify the

type of power that is needed. As a part of startup process when a PoE connection is made, the

PD can advertise its power class, which is an indication of how much electrical power is required

to operate.

5.0 Megapixels

Infinique’s IP Cameras are capable of generating images at multiple resolutions, from 1.3

megapixels to 5.0 megapixels. Images captured on these high resolution megapixel cameras

look much bigger, wider, and clearer than at lower resolutions. Infinique offers IP cameras with a

variety of resolutions to help create the optimum network environment.

IPv6

Infinique’s IP Cameras support the new Internet Protocol Version 6 (IPv6) that is designed to

succeed Internet Protocol version 4 (IPv4). IPv4 is the first publicly used Internet Protocol and has

been in operation since 1981. IPv6 uses a 128-bit address, whereas IPv4 uses only 32 bits.

SD Card Memory

Infinique’s IP Cameras support SD Card Memory Backup. In case of network crashes, these

cameras can backup surveillance images on the SD Memory Card optionally. You will still be

able to check images captured while the network was down.

Dual Power

Cameras with dual voltage options to accept either 24V AC or 12V DC power sources and will

automatically switch to the appropriate mode upon receiving power.

High Resolution

The ability of the camera to resolve fine detail can make the difference in obtaining evidence or

not. Resolution is measured by a chart with converging lines of higher and higher density. The

resolution is the line density where the camera is no longer able to reproduce individual lines. For

this reason, resolution is expressed in terms of TV lines (TVL). The higher this number is, the better

the picture quality.

Optical Zoom

The Optical Zoom feature provides a quick way to automatically zoom into a defined area

where motion is detected. It allows the operator to zoom on a subject swiftly to identify any

possible intrusion in a restricted area. Infinique’s cameras are equipped with both optical and

digital zoom.

Heater Blower

Cameras exposed to extreme heat and cold environments could potentially damage them. To

combat the extreme temperatures, Infinique’s outdoor cameras are equipped with heater and

blowers which automatically activate upon reaching the cut-off temperatures, thus ensuring safe

operating conditions. The blower remains on at all time, keeping cameras cool and fog free.

HC IR LED (High Capacitor)

Infinique’s Super Night Vision cameras have High Capacitor IR LEDs which offer long-range

viewing at night with its intelligent IR compensation providing perfect exposure of subjects.

C/CS Mount

Infinique’s Box Cameras can be fitted with either C or CS mount lenses. Cameras and lenses are

generally CS mount rather than C mount. With CS mount cameras both types of lenses can be

used but the C mount lens requires a 5mm ring to be fitted between the camera and lens to

achieve a focused image. With C mount cameras it is not possible to use CS mount lenses as it

is not physically possible to mount the lens close enough to the CCD to achieve a focused

image.

H.264 CODEC

Infinique’s IP Cameras employ true high-definition video and H.264 codec compression,

streaming up to 30 images per second (ips) at 1920 x 1080) resolution, and 60 ips at (1280 x 720)

resolution, offering efficient bandwidth utilization with the highest-quality video.

H.264/MJPEG Dual CODEC

The Dual Codec streaming feature transmits simultaneously H.264 or MJPEG video, enabling

real-time monitoring, high-quality recording, i-phone/mobile monitoring, E-mail notification and

saving to SD memory. Infinique’s IP Cameras that employ Dual Codec comes with all these

advanced features.

Progressive Scan

Infinique’s IP Cameras that have Progressive Scan CCD capture each frame at its entire

resolution and smoothly reproduce images of moving subjects. Plus, if we compare its 1,280 x

960 jpeg images with conventional VGA (640 x 480) JPEG images, we find that for the same

camera position, the image covers a four-times wider area. This feature allows for better detail

for video of moving objects, such as faces and license plates on automobiles.




HLC - High Light Compensation

High light Compensation suppresses strong light sources such as the headlights of automobiles,

flashlights etc., in dark places and prevents camera from being blinded.

Motion Detection

Motion Detection function enables the camera analyze successive frames of video and can

detect movement in the scene. Units that use MD utilize various types of thresholds that can be

programmed by the user to prevent or reduce false alarms. If the type or level of motion crosses

these thresholds, the unit can automatically react in a way that benefits the system. In cameras

with MD, a visible alert message can appear on the screen. In some models, a contact output

from the camera can be used to switch a picture to a particular monitor, calling the attention of

the operator.

Digital Signal Processing

Infinique Cameras can deliver high quality images utilizing a unique digital processing

technology. The powerful intelligent processing also drives numerous unique DSP features

including Auto Image Stabilization for camera deployment in areas that may be prone to wind

and other sources of vibration. Its advanced processing also has noise filtering. DSP reduces the

digital bandwidth storage requirements compared to conventional cameras.

Relative Savings in Transmission Bandwidth and Storage

Choosing Camera Lens

Different lens sizes can change the viewing angle of a camera. This is demonstrated in the

pictures below.

Calculating the focal length of a lens For a 1/3" CCD Camera the following formula can be applied to calculate the focal length

requirement of a lens.

Distance from object (d) x Chip Width(C)

Focal Length (L) = —————————————————— , C= 4.8mm for 1/3” CCD chip

Width of the Area (A)

To focus on an area 5m wide from a camera installed 20m away would be:

20 x 4.8 / 5 = 19.2, A lens with a focal length of 19.2mm will be required for this scenario.

Focal Length

The Focal Length is measured in millimeters (mm). It is the distance from the lens to the surface

of the image sensor. A shorter focal length (2.5 mm) gives a wide angle view, and a longer

focal length (16 mm) will result in a narrower view.

Vari-focal Lens A lens type where the focal length can be varied to give the exact image desired. This is similar

to a manual zoom lens.

Angle of View The shorter the focal length, wider is the angle of view

The longer the focal length, narrower is the angle of view

The smaller the CCD chip, narrower is the angle of view

Depth of Field Depth of View is the distance within which objects in a picture are in focus. A large Depth of

Field means almost all objects in the Field of View are in focus. A small Depth of Field means

only a small section of the Field of View are in Focus. Factors leading to a greater Depth of Field

are:

1) Using a Wide Angle Lens

2) High F-Stop

3) Using an Auto Iris

CCD Chip Size

The size of the CCD Chip used in the camera affects the angle of view. A smaller CCD Chip

gives a narrower viewing angle. The table below specifies the angle of view for different sizes of

the CCD chip.

F Stop

F Stop is the ability of the lens to gather light depending on the aperture and focal length.

The F-Stop or Aperture has 2 measurements. Maximum Aperture / Minimum F-Stop is attained

when the lens is fully open. Just before the lens completely closes Minimum Aperture /

Maximum F-Stop is attained.

C/CS-Mount

C or CS mounts are the two standard CCTV camera lens mounts. The difference between the

two is the distance between the lens and the CCD image sensor. The C-Mount lens has a

17.5mm flange back distance. The CS-Mount lens has a 12.5mm flange back distance.

Auto / Manual Iris

Iris is the adjustable opening (mechanical diaphragm) through which light can pass and be

regulated. Auto Iris is a lens in which the aperture automatically opens and closes to maintain

proper light levels on the camera's pickup device. Auto Iris lenses are used for applications

where light conditions are changing, such as in outdoor applications.

In Manual Iris the lens has a manual adjustment to set the iris opening (F stop) in a fixed position.

Generally Manual Iris lenses are used for fixed indoor lighting applications.

Video / DC Drive

Majority of CCTV Cameras will be able to use both types. Video Drive lenses contain circuitry

which converts video signal from the camera into iris control. Direct drive Lenses require the

CCTV camera to contain the circuitry.
