New Update

With increasing Internet bandwidth and the need to access information
anytime, anywhere, there's a thrust towards moving everything over IP. So,
whether it's voice, video, IM or even surveillance; everything has moved over
IP. At all leading public places and events, IP-based surveillance is fast
becoming the de-facto standard for monitoring security. So, whether it is the
upcoming Olympics in Beijing, traffic lights in New Delhi or the newly
constructed malls , IP Surveillance implementations are on a roll across the
world. Enterprises too are deploying IP surveillance to safeguard their data
centers, ware houses and even offices. And like we've mentioned before, IP
cameras can be accessed from anywhere across the globe, all you need is a web
browser and access to broadband Internet connectivity. In this story we take a
look at the various IP surveillance solutions available in the market, and what
all you need to know

before implementing IP surveillance.

Choose the best one for your need

One of the oldest forms of Surveillance which is still popular is CCTV. Many
vendors provide IP based CCTV Surveillance. However, you can look beyond the
CCTVs towards other intuitive solutions. You can deploy a Standalone CCTV Box
that connects to a TV or monitor and supports around 16 channels in one box.
Another one is DVR card-based surveillance; here you need a decent system with a
PCI slot for inserting the DVR card. You can directly connect your cameras to
this DVR card. Here again the average support is for 16 channels. The problem
with CCTV based IP surveillance is that you need to have dedicated cabling for
it. With IP Surveillance you do not need any special cabling, all you need is an
open network port to deploy an IP camera. Another advantage with IP cameras is
that they can draw power from Ethernet ports. So, if you deploy a camera at a
place where there is no power around or where there's a possibility that someone
can disconnect power, PoE comes handy. IP cameras come in different flavors: PTZ
(pan,tilt and zoom), fixed, low light cameras, etc. IP cameras support
progressive scan, that allows you to remove still images from a video and save
them separately.


D-Link IP Cameras

DCS-6620


It has motorized Pan and Tilt functions and can cover 90 degree up and down
and 270 degree side-to-side. The camera supports 10x optical as well as
digital zoom. In digital zoom when you zoom in, the images get pixilated
while optical zoom gives a better view of remote objects. DCS -6620 comes
with an external I/O port, which can also be used to connect to an external
sensor or alarm device. It supports both PAL and NTSC video formats with
support for MPEG4 as well as Motion JPEG video codec types. This camera also
has an A/V output through which you can connect it to a TV for local
viewing. The camera is easy to implement, just connect it with an Ethernet
cable and plug it in. It will automatically acquire IP address if you have
DHCP running. Now just open this IP address in any ActiveX-enabled Browser
and you can start monitoring from anywhere. You can also move the camera and
record videos through its Web interface. It also comes with a small remote
through which you can perform tasks like Pan, Zoom, stop camera etc.

DCS-3420

D-Link calls this Wireless Day and Night Internet Camera. It supports 0.5
lux light sensitivity, which allows camera to capture videos in minimal
light. However you will have to buy this lens separately. In case you want
to fix this camera at a location where there is no Ethernet cable available
or if it is likely that one candisconnect it easily, then you can configure
the camera to work over Wireless. It supports WEP-128 bit and WPA-PSK
encryption over wireless.

All D-Link Cameras come with D-Link D-View
Cam softwarewhich alllow users to manage 16 cameras through a single
console. Users can also view split display from 4 CH split display to 16 CH
split display. Users can also record videos through this software.

D-View Cam also comes with a tree-structured
management tool called eMap. With this tool you can visually represent all
your surveillance devices running on your infrastructure.

Most of the surveillance systems support integration with third party systems
such as alarms systems, access control, and for large area applications like
traffic management or building management.

How to choose a surveillance camera

You should look for a camera which provides 25 fps or faster frame rate, as this
results in jitter free images. Monitoring through a Web interface is another
must, as it allows you to monitor your infrastructure anywhere, anytime. Many IP
cameras allow you to monitor through wireless devices. You can also access
surveillance video through your mobile. Make sure that the camera supports
standard wireless encryptions such as WEP 128-bit or 256-bit, WPA-PSK, etc.
Another important thing to look for is motion detection, as this not only alerts
you as soon as a new event is detected but can also help in recording important
events.

If you need to prove a happening, with date and time, look for the time stamp
feature. You can also look for cameras which provide embedded watermarks on the
footage, to reinforce authenticity. To protect yourself from attacks like
sniffing or IP replay, look for cameras which support encryption. To counter
these threats many people change the default port on which surveillance video is
being streamed. Other things you need to look for are motorized control, remote
control, email based alerts etc.

Sony IP
Surveillance Cameras
Sony SNC-CM120

Sony recently launched its new 1.3
megapixel IP security cameras: SNC-CM120 Megapixel Fixed-type Camera and
SNC-DM110, SNC-DM160 Megapixel Network Mini-dome Cameras. These cameras
support ExwavePro and light funnel technologies.



ExWave Pro technology combines Exwave HAD technology with color filters and
progressive scanning to deliver higher resolution as well as sensitivity.
These cameras are able to deliver clear images even in low light conditions.
This works even if the resolution of an IP camera is larger than 1,000,000
pixels. As these cameras use the light funnel technology, they can combine
two pixels vertically as well as horizontally to form one larger pixel.
Since this area is four times larger as compared to a single pixel, it can
convert large quantity of light into electrons, thus producing a strong
electric signal. This feature can automatically be activated depending upon
the light conditions and can also be scheduled. The cameras also support PTZ
(Pan, Tilt, Zoom) functions, constant bit rate algorithms, intelligent
motion detection, flexible gamma curve settings, as well as MPEG4 and JPEG
dual codec capability.

Choosing storage for IP surveillance

Storage of the video footage is a key part of any surveillance system. There are
however problems in storing images generated from IP cameras, as even a single
camera can generate more than 10 GB of data in a single day. Vendors offer
dedicated storage for video surveillance. For instance, Seagate offers Series
SV35.3 hard drives which are only meant for Video Surveillance. They have
increased data rates upto 480 Mb/s with SATA interface. According to Seagate
these drives can operate under drive case temperature of upto 75 degrees C.
Also, as surveillance system performs constant write operations on a disk, using
storage devices such as NAS can degrade the performance of a solution, because
these devices are designed for environments where balanced read/ write
operations take place.

This is a standalone
CCTV based digital surveillance System. The solution mainly compromises a
DVR Mainframe which is connected to a TV. The DVR which we received
supported 16 CH and with multiple cameras it supports 2x2, 3x3 and 4x4
channels.The Box has a hard disk where all videos can be stored. It also
comes with a hard drive lock to secure the disk. It also has a CD R/W drive
for backups and a USB port for connecting external hard drives . You can
freeze, zoom, rewind or fast forward recorded videos up to 16x speeds. When
connected with a camera with built-in mic, you can also hear remote audio.
For security, you can lock DVR Mainframe box with a password. Deploying DVR
Mainframe is quite simple; it can automatically acquire an IP address
through DHCP or can be assigned a static one. You can remotely access the
Box through a browser or through its proprietary software. The box also
supports motion detection; upon detection it generates a loud alarm to alert
users. The company also provides DVR cards which can work on any decent
Windows XP machine. An 8 channel DVR card costs about Rs. 14,900.
