What is a Fixed Camera?
A camera can be fixed to only look at one specific view and such cameras are called Fixed Cameras. 1 out of every 1000 cameras you see around are Fixed Cameras. They cost less and are chosen to monitor a specific path, object, room or asset.
What is a PTZ Camera?
PTZ stands for Pan - Tilt - Zoom.
While PAN means panning the camera which is like horizontally parallel movement of a camera.
Tilt means as it stands for which is tilt of the camera up or down.
Zoom means zooming in a particular area.
Difference between Fixed and PTZ Cameras:
1. Fixed vs. PTZ: A camera can be fixed to only look at one specific view or it can be movable through the use of panning, tilting and zooming (i.e., moving left and right, up and down, closer and far away). Most cameras used in surveillance are fixed. PTZ cameras are generally used to cover wider fields of views and should generally be used only if you expect a monitor to actively use the cameras on a daily basis. A key reason fixed cameras are generally used is that they cost 5 to 8 times less than PTZs Cameras.

Royal Wedding "Live from Westminster Abbey" with Y-cam -Britian's Prince William
Didn’t receive your invite? Well don’t panic! As we will be there as your eyes and ears – well, our cameras will! Watch this years must-see celebrity wedding, LIVE from Westminster Abbey with Y-cam!
Dreams do come true, for Kate, and for Y-cam. Being a proud UK business, we were thrilled to “get the call” from Kate herself asking us to be involved in her wedding, and indeed the wedding of the Century!
Kate and William are apparently “big fans” of Y-cam, regularly using them for checking in on their elderly relatives from their iPhones, so when thinking about capturing their magic moment, there was only one company for them to approach.
Y-cam will be discreetly installing a number of IP cameras throughout Westminster Abbey and will be streaming them live through our dedicated microsite – ensuring that viewers have the best seat in the house! Viewers will also have the opportunity to shout their well wishes to the happy couple via the Y-cam Bullets 2-way audio function, allowing you to get up close and personal with the Royals – just be sure to keep quiet when the Archbishop asks if there are any objections to the wedding!
To commemorate this momentous occasion, Y-cam will be producing a “Limited Edition” version of our award winning Bullet – reissued especially as Y-cam Bullet Royale. The camera comes loaded with all the functionality of our traditional Bullet; but has the added feature of playing “The Wedding March” whenever it detects motion.
“We are utterly thrilled that Wills and Kate are getting hitched under the watchful eye of Y-cam, and we hope our Bullet Royale camera certainly does them and the event justice” commented Lirpa Loof, Product Manager for Y-cam Solutions, “William has even been in touch to get some other Y-cam models for his personal use, he mentioned something about the wedding night, so we hope he gets all the footage he wants.”

Understanding Picture Quality
In the last post on 7th April 2011 we had covered the different technologies available to you and a broad idea of the kind of output you can get from them. At Dee Cee Security Systems Pvt. Ltd. we are committed to suggest you the right technology and the right solution which exceeds your expectations and is within your budget.
Here we will give you a idea of the main aspect of CCTV Cameras which every buyer is looking for but gets confused when he sees technical words like CIF, 4CIF, D1,etc.
Before we go into understanding the above, you need to understand one word which "PIXEL". What is a Pixel?, while you hear megapixel, HDTV and other terminologies nowadays, very few people understand that they are based on amount of pixels they support.
In simple terms, PIXEL stands for Smallest Picture Element. See the below picture:
Image Source: Wikipedia.com
What you see above is a Monitor on the left. On the right side you see a image which is zoomed in version of the image. The selected area is shown as a square on the left side.The element has been red colored and named as Pixel. That is a Pixel. If we name that Pixel as P0 and the next one as P1,P2,P3...... and so..on... then we would get the image resolution. A image resolution bascially refelcts the total number of pixels the image.
Do understand the number of pixels is directly proportional to quality of picture. So higher the number of pixels better the picture clarity.
Following table gives you a idea of the number of pixels expected from a Analog Camera.
To understand the above, i will give you example, QCIF which gives you a resolution of 176 X 144 in PAL( used in Asian Countries) means it will give you a resolution of 176 Pixels X 144 Pixels horizontally and vertically. Thus as we go higher the image size increases.
The following is table of Digital Video Resolution ( or IP Camera Resolution):
So you can see the number can go a lot higher in Digital Video Resolution compared to Analog Video Resolution thus offering you Best picture Quality.

Selection of CCTV Surveillance - Available Technologies
Like i promised in the last post, i would be covering the different technologies available at your disposal in the field of CCTV Surveillance which will help you to make the right choice for your requirement.
There are two technologies which are available to us on the basis of transmission & storage method, quality of picture, which are:
1. Analogue Cameras
2. Digital/IP Cameras
1. Analogue Cameras: Analog Cameras as the name suggests give analog output and the mode of transmission is analog. Analog cameras general come in different resolutions which you mostly hear, such as 420TVL which stands for 420TVLines or 480TVL or 540TVL. As the number of TVL go up the picture resolution or clarity goes up. Transmission of Analog output is done by using RG-59 cable to a Television or a Digital Video Recorder (DVR). DVR converts the signal from analog to digital and records it in a Surveillance Hard Disk installed in the DVR. 95% of the DVR's today are IP-enabled which means the data can be viewed remotely by accessing the DVR. In order to do so the DVR has to connected to internet by providing it a Public Internet Address.
Following is a recorded image of a analog camera having 480TVL resolution:

The above gives you a brief idea on the expected quality of the image from a analog camera.
2. IP/Digital Camera: Digital Surveillance Cameras are usually referred to as IP Cameras in the security field to avoid general name conflict with Digital Cameras used for taking snaps. IP Cameras as the name suggests give a digital output and digital mode of transmission is required here. Network Cable commonly referred to as Cat-5 or Cat-6 is used here. Digital Output coming from a IP Camera cannot be recorded in a DVR, it can be recorded in a Computer, Server(placed remotely or lcoally) with the help of the Video Management Software provided along with the IP Camera or on Network Video Recorders (NVR) or Hybrid DVR's. Most manufacturers provide free Video Management Softwares for upto 4 IP Cameras while others provide it free for more number of cameras. But as the number of Cameras increase you can keep in mind the cost of Licensing Software as you go along.

While the difference between the two images is quite visible, IP Cameras offer a advantage in terms of offering better picture quality as the choice can go to Megapixel Cameras when the resolution becomes 2 to 10 times the resolution of the expected resolution from a Analog Camera.
A digital "Megapixel IP camera" with very high resolution (1280×1024) – (below)
Image Source: www.globalsecurityllc.com
While the above gives you a brief knowledge on the technologies and the quality of picture you can expect , do understand that going forward Surveillance Solutions based on IP will gain steam due to the picture clairty, compatibility offered by them it terms of Video Analysis and Real time alerts. The real advantage which Analog offers in comparison to IP is the price. Production of IP Solutions in mass volumes is yet to take place and thus a cost anywhere between 4-5 times more then a similar analog camera at the entry level.
I hope the above helps you in making the right decision in choosing your Surveillance Solution.
