IP Camera Advantages

The arrival of IP cameras that connect to each other, network video recorders, video surveillance servers and all manner of other infrastructure over standard Ethernet cabling has been one of most important recent advancements for the CCTV industry.  IP cameras connect using Ethernet as used by computer networks on standard Cat5e or Cat6 cabling allowing for easy routing and switching of the packetized video data for connectivity to all manner of devices.

IP cameras have changed how video surveillance networks are designed, deployed, utilized and maintained.  They have many advantages including:

Ultra high resolution (megapixel)

Old Analog CCTV developed over time from very poor VHS style quality up to the most recent resolution known as 960H pioneered by Sony.  This is 960×582 (PAL) pixels, equivalent to 0.5MP (500,000 pixels or Half A Million Pixels), also known as 700TVL.

Modern IP cameras with their latest generation image processors are fast approaching 12 Million Pixels with 3, 4 and 5MP very common today.  A 4MP camera is recording footage at 2560×1440 pixels.  This dramatically increased pixel resolution allows for much greater identification success.

Even the most rudimentary entry level IP camera records at 1.3MP which is 1280×1024.  At this resolution an area 4x larger can be covered for the same resulting identification resolution.

Comparing the most standard 2MP “High Definition” IP camera which has a resolution of 1980×1080 to Analog is like comparing BlueRay home theater to VHS.

The most common format today is 2MP with 3MP and 4MP becoming more common my the day.  The 2MP standard is 1920×1080 pixels in a 16:9 format.

Forensic Inspection

Whenever reviewing live or playback recorded video, IPs cameras being of larger pixel densits allow user to digitally zoom in more on a particular region with minimal loss of definition.  This helps to capture important details for item or facial recognition and dramatically improves car license plate readability.

The greater megapixel resolution of IP camera pictures allow you to overcome one of the significant drawbacks found along with traditional analog cctv cameras – the lack of forensic detail they provide.  In fact as people have become more accustomed to DVD and BlueRay HD video over older TV and VHS there have been many cases where old analog CCTV footage has been dismissed by jurors as their expectations of clarity have changed.

For all home owners, businesses and organizations still using analog CCTV hoping that recorded footage may be suitable as evidence in future court matter we strongly encourage an upgrade.  Expectations have changed.

In fact many police forces now recommend High Definition 2MP, 12 fps medium or low compression as the minimum standard required if CCTV footage is to be used for forensic investigations and evidence.

Reduced costs

First, while it is true that the latest generation IP cameras are more expensive than Analog cameras the infrastructure to deploy and connect IP cameras and to then maintain is significantly cheaper.  With IP based systems there is no requirement for specialist power distribution boxes ( such as these – 9Ch Power Box ) or difficult to terminate and maintain Coaxial BNC connectors which is a significant saving.

Secondly; the trades people required to deploy Ethernet Cat5/6 cabling are a lot easier to find than cabling technicians versed in BNC/Coax.  Also the cost for a trades person to buy computer data cabling per meter wholesale is less than Coaxial cable and is much easier to fine being available at every electrical wholesale outlet in business.  Therefore typically cable cost and installation labour charges are lower for IP systems.

Thirdy; the time required to terminate a Cat5e/6 cable is probably one tenth the time required to properly terminate and test a BNC/Coax cable.  Over many cameras this difference in time certainly leads to reduced install and maintenance charges.

User friendly installation

IP camera can be connected to your existing network, and with standard RJ45 port. It has capability of utilizing PoE (Power over Ethernet) technology for power.  The PoE technology can allow cameras to use a single Ethernet cable for both transmitting video signal, power, as well as audio signal. Pull one cable to the nearest Ethernet port and you’re done. No home-run cabling, no power considerations, less hassle, and less cost.

Most IP Network Video Recorders for the 4, 8 or 16 camera markets will include PoE Ethernet ports built in so there is no requirement to install seperate PoE Ethernet switches.  Thsi makes the installation of an IP system for home or small business VERY simple.  It is essentially “Plug-And-Play”

Remotely live view and access, control

IP camera with built-in web server, just type the IP address, you are allow to access the IP camera from your local network or even over internet. Typically you will get the free video management software, which can be installed in any PC, and with this software, you can manage up to hundreds of IP cameras. You can watch live videos in split view, performing pan/tilt/zoom function, even video recording and playback on your PC.

Easy to use

The vast majority of IP cameras comes with many software, a IP camera search software provides a search function that rapidly scans your network for cameras. Simply add the cameras in your watching window, and you’re in business. And like any kind of IP camera, you can view and manage functions remotely, via your network and also over the Internet.
