When choosing a video surveillance system, you want to go with the best
video quality for the buck, and with a Network IP camera, there are 10
reasons why you should consider them over 20th century CCTV cameras.
1.
End Your Interlace Issues:When you move to a Network IP camera, you get
rid of the interlace problem with moving video. If you have seen a
moving image with lines in it, that is interlace, where two fields make
up one complete frame using interlace scanning.
With a network
camera, one complete frame is used during a progressive scan, so your
moving images are much clearer than with a CCTV camera.
2. Power
Your Cameras Over Ethernet: When you power your cameras over your
Ethernet network, you save money, and increase the reliability of your
network.
You can't power your CCTV camera over your Ethernet
network, and this is beneficial because you don't need a power outlet to
power a network camera. This will save money on electricity, and lets
you perform centralized backups.
All network cameras can be
powered over Ethernet, whether they have built-in support, or not. If
the support is not built in, you can purchase an injector/splitter,
which will add the electricity to the Ethernet cable, then peel it off
to power the camera.
3. Megapixel Resolution: CCTV cameras are
limited in their resolution, and most can't give you megapixel
resolution. 1 megapixel is 10x the resolution of CIF, which is 352 x
240.
With a network camera, you get better resolution, making for
easier identification when you review the video. No longer will you get
blurry video, especially when the subject is moving.
CCTV cameras are limited to 4CIF, or 704 x 480, while IP cameras are well past to 3 megapixel, or 2048 x 1536.
4.
Smart Cameras: CCTV cameras are dumb; they just send video to a DVR. A
network IP camera is smart, as it offers alarm management, image
enhancement, license plate and facial recognition, and is built with the
latest technology, and is really a little computer with a camera lens.
This
allows you to have more detailed video, which helps in identifying
suspects, and you can have alarm or motion activation, and unlimited
scalability.
This allows you to set up specific motion detection
areas that you want to watch, within your cameras image, and if no one
comes in those areas, even though they are in the field of view, it will
not be recorded. Examples are a door in a hallway, or a specific part
of a hallway.
5. Integrated PTZ Control:With a CCTV set-up, you
need separate cables to control the PTZ feature of your camera. With a
network camera, it's all done over the network. With integrated I/O, it
can trigger anything, and be triggered by anything.
This results in less labor, cabling, cost, and increased functionality and integration than with a CCTV camera system.
6.
Built-in Audio: With a CCTV camera, very few have built in audio. It
requires a separate cable, and a DVR that can accept an audio file. With
a network camera, audio is usually built in, and is captured at the
camera. You can integrate it with the video feed, or keep separate. You
can also have two way audio, to and from the camera.
This allows
you many possibilities like ease of installation, cost savings,
synchronized audio with video, and two-way audio; duplex, half duplex,
simplex.
With integrated audio, you can have remote dialog and
allow gate or door access, as well as listen in on the location. This is
a great way to help with surveillance scenes.
7. Your
Communications Are Secure: CCTV video cameras are easy to tap into the
video and replace it with a signal from another source. In the film, Mr.
& Mrs. Smith, Brad Pitt changed the video in an elevator camera
before it was destroyed.
With IP cameras, they require
authentication, and with their encryption, you cannot tap into the
signal, giving you complete privacy, secure image capture and
transmission, and an evidence trail.
8. Flexible And Cost
Effective Infrastructure Choices: With CCTV cameras, you have expensive
coax cable, fiber, and unreliable wireless installations. The further
you go from your DVR, the worse the images. When you add power or audio,
it just makes things harder.
With a network camera you have an
established IP address, giving you clear digital pictures with no loss
of quality. You can send many streams of video from dozens of cameras at
one time, giving you a single wire network that allows hundreds of
simultaneous full frame video streams.
This gives you better image quality, flexibility and scalability in a lower cost to operate than traditional CCTV cameras.
9.
A True Digital Solution: A network video surveillance system will give
you much clearer video due to the images being digitized on the spot.
With a CCTV camera, you loose image quality every time you transfer the
video from the analog signal when it is digitized in the cameras Digital
Signal Processor, which is then converted back to analog to run up the
coax cable, which is again digitized at the DVR for recording.
With
a network camera, the images are digitized once, and they stay digital
with no more conversions, resulting in the clearest video you can get
from a video camera.
10. The Lowest Total Cost Of Ownership: When
you compare the cost per camera, and the flexibility and performance a
network camera gives you, it makes sense to go with the Network IP
camera.
Things to consider are the back end applications and
storage costs, as well as using open-system based servers, vs.
proprietary hardware like a DVR. The software that comes with the camera
is usually functional enough for basic viewing, though control center
software allows you to watch multiple locations at one time.
Also, you are using your current network infrastructure, which can save you money in the long run.
It's clear that the future of video surveillance is with network cameras, let's sum up the benefits:
Remote accessibility
Easy and future proof integration
Scalability and flexibility
Clear video with no interlacing problems
Cost-effective • Lower installation costs
Distributed intelligence
Proven technology
