Definition

The world of video surveillance is moving toward the IP network. An IP Network Camera can be defined as a camera with networking and video processing combined into one unit. A network camera has its own IP address and the computing functions necessary to handle network communication. It captures and transmits live images over the network, enabling remote viewing and user control from anywhere, anytime.

Development

In the field of video surveillance network monitoring, IP network monitoring by the network monitoring stripped out, developing as unimaginable speed. Just the past three years, the production and sales of network cameras and analog cameras share constitutes a significant in security market. IP network cameras Proportion has increased from 5% to 25% today. Caused this change of a variety of reasons, such as the development of the network camera technology to achieve high-definition real-time image, product type has become increasingly diverse, the improvement of the network environment has brought greater bandwidth and higher speed.

FAQ

What is an IP Camera?

‘IP’ stands for Internet Protocol, which is a protocol for transmitting data across a network. An IP Camera or Network Camera is a camera that plugs directly into your network router, and is not reliant on a computer to work. Data from the IP camera is transmitted through the network, and can be securely viewed at a remote location.

What is needed to use an IP Camera?

An IP Camera requires a High Speed Internet connection (such as DSL), a router and ethernet cable. A computer is needed to view the data, however the camera works independently of the computer.

What is the advantage of an IP Camera over a USB Web Camera?

An IP Camera does not depend on a computer, and does not require a specific application to run and transmit images. A USB Camera is dependent on a computer, and requires the computer to be powered on and logged in.

Why choose an IP Camera over a standard camera?

An IP Camera allows you to view images on your local computer and from remote locations without needing a dedicated Observation System or DVR. These cameras are easy to install and configure, and can be located anywhere that a network cable can be run.

What is required for Remote Viewing from anywhere in the world?

To view the camera images remotely, it must be correctly configured within your internal network. To view the images remotely, the router must be configured to allow for port forwarding.

Computers, IP Cameras, and other devices inside the internal network can only communicate directly with each other within the internal network. Computers and systems outside the network cannot directly communicate with these devices. When a system on the internal network needs to send or receive information from a system outside the network (i.e. from the Internet), the information is sent to the router.

When a computer on the external network (Internet) needs to send data to your internal network, it sends this data to the external IP address of the Router. The Router then needs to decide where this data is to be sent to. This is where setting up Port Forwarding becomes important.

Port Forwarding tells the router which device on the internal network to send the data to. When you set up port forwarding on your Router, it takes the data from the external IP address:port number and sends that data to an internal IP address:port number (i.e Router External IP 216.13.154.34:port# to IP Camera Internal IP 192.168.0.3:port#).

Is my IP Camera Secure?

The images are encrypted and control access is granted by inputting a User Name and Password. This helps to prevent unauthorized people from gaining access to your camera.

Do I need a Static IP Address?

A static IP address is not needed to connect to the camera. DDNS provides you with a URL (web address) that always points to the most current IP address at the location of the camera. Other DDNS services can be used.

A static IP address is useful to prevent interruption to the connection with your camera (as the DDNS Service syncs to the new IP), however it is very common for Internet Providers to lease your IP address for a set amount of time, and then to release you a new IP address.

What is DDNS?

DDNS is Dynamic Domain Name Service. A DNS (Domain Name Service) translates domain names (i.e. http://sierracctv.no-ip.org) into a static IP Address (61.140.22.108). A DDNS (Dynamic Domain Name Service) will translate a domain name into a non-static IP address (an IP address that is not fixed, and can change often).

How do I know if I have a Static or Dynamic IP Address?

Check with your Internet Provider – they will be able to tell you if your IP address is Static or Dynamic. Most residential Internet service plans use dynamic IP addresses.

If you’re thinking about installing a new video surveillance system, then you have to decide between an IP or analogue video format. This Article will make your decision easier.
Analogue Cameras:

PROs:

– Cheaper cameras – cost effective solution
– Uses less hard-drive space which results in many months of footage
– Can be connected to existing camera systems and all brands work with each other
– Analogue systems are very stable and need no maintenance
– Analogue cameras don’t depend on your network and will still work when the network is down
– Approved technology that works better with motion and difficult light situations
– Big variety of models such as big outdoor bullets or small hidden cameras and many more
– Analogue system can also be viewed over the internet and mobile phones

CONs:

– IP cameras have a much higher resolution then analogue cameras
– Usually more cable is used – But this does provide better stability
IP Cameras:

PROs:

– Very high resolution – so you can zoom in without quality loss
– The existing home/company network can be used, which saves long cables
– Good wireless functions through WiFi network without interference
– Thanks to higher resolutions, faces and number plates can easily be identified
– Very far distances can easily be reached with wireless senders and receivers
– IP cameras can be configured through the network

CONs:

– IP cameras are in general higher-priced
– High resolutions require allot of bandwidth which can sometimes slow down your network speed
– Usually one camera brand can’t work with another + NVR licenses are required
– High resolution internet viewing is slow in some areas with standard internet connections.
– High technical skills are required in order to configure and maintain IP camera systems
– More hard-drive space is required
– IP cameras can’t work when your network stops working

Summary:

IP cameras have a higher resolution then analogue cameras but are higher-priced.

However, Sierra CCTV sells the newest technology for fair and competitive prices!
This means that we offer great resolutions (800 to 1200 TVL) on analogue cameras and very good prices on IP cameras.

Love Everybody – The Story of Big Kenny’s famous two words.

“Love Everybody is my personal motto and our family crest!” – William “Big Kenny” Alphin

“Around the year 2000 I had a vision that my world would be expanding and I would be a voice in front of a lot of people. The dream was so vivid. Just two simple words that would be my motto. I knew I had to do what ever I could to spread the message as I traveled and toured around the world. I put “Love Everybody” on my guitars my jewelry and my cloths, stickers, patches, anywhere I could just to spread those two words.”

“I know every time I see the words and every time others see the words, it reminds us how simple it is to make things better everywhere. I dream it will be plastered on billboards from country roads to Time Square to cities and villages around the world. The message is the most powerful I know. “

“I tell people Bono says ‘ONE’, Bob Marley says ‘One Love’, and this country boy says it as simply as he can: “Love Everybody!”

“I hope to leave this as my legacy for all to carry the banner forward.”

 “Highlight the good, inspire greatness & encourage mutual responsibility for the betterment of humankind.”
