Frame Rate: The frame rate is used to describe the frequency at which a video stream is
updated is m
easured in frames per second (fps). If you want more accurate video then the
fr
ame rate should be kept high. Lower the frame rate, lesser the image details.
Gain Control:
When camera produces a quality picture, it needs a sufficient amount of
light to produce a minimum stable picture, in case the light condition reduces to a certain
level, there is insufficient light to the
(A
utomatic gain control) increases the amount of amplification in these conditions to
bring the video signal up to the minimum required level. Besides increasing picture
signal, AGC also helps to reduce noise and picture attenuation.
D
aylight saving time (DST): It is practiced especially in countries such as Australia,
Canada and the United States to save energy because it refers to a time for saving daylight
during the summertime so that afternoons have more daylight and mornings have less.
Typically clocks are adjusted forward one hour near the start of spring and are adjusted
backward in autumn.
Q
oS & IP filtering: Quality of service plays an important role while viewing video over
the data network, this IP camera supports QoS parameters which can help prioritize the
video traffic along with the managed switches/ routers in the network to ensure best
delivery of the video when running multiple applications over IP network

an either white list or blacklist an IP address. This restricts unauthorized access to the IP
camera.
Infrared (IR) cut-off filters: They are used with color CCD or CMOS imagers to
produce accurate color images. An IR cut-off filter blocks the tran

hile passing the visible. This can be done with two optical techniques: absorption or
reflection. Absorptive filters are made with special optical glass that absorbs near infrared
radiation. Reflection type filters are short-pass interference filters that reflect infrared
light with high efficiency.
