Dont go hybrid, Tavcoms view: Analogue, Hybrid or IP CCTV

October 27, 2009

IP is here and offers more than hybrid or analogue systems. So Mark Harraway argues here. Mike Tennent of Tavcom Training sets out the first part of his response below.

Love them or loathe them, the number of electronic security systems deployed in our buildings and on our streets has burgeoned in recent years and, without a seismic reversal of public and political opinion, that trend is set to continue, not only in the UK but around the world. Hard facts and figures are not easy to come by and are invariably hotly disputed but there can be little argument that we are now – for better or worse – a locked in, locked out, closely watched and frequently recorded society. CCTV, access control, intruder alarm, perimeter defence and other electronic security systems are ubiquitous features of modern life.

This proliferation of technology has meant ‘boom times’ for those who grew up with this new industry but now the goalposts are on the move. The rapid cross pollination and convergence of technology involving the security, IT and other sectors is creating exciting new opportunities for installers from other sectors to enter the security arena and dramatically enhance their career prospects.

Will an IP based CCTV solution cost more than analogue?

October 22, 2009

The answer to this question depends where you start from and where you want to end up.

Axis Communications carried out a very interesting exercise last year to answer this very question and the results were quite revealing. In a new installation (i.e. Cat 5 is installed as part of the building process) IP is always more cost effective and on other occasions for camera counts above 40 cameras, IP is still more cost effective.

We have also seen this in a number of projects we have undertaken with partners because these savings are brought about by such things as more efficient cabling (One cable to carry everything rather than multiple cables.), more cost effective use of storage (no wasted channels and scalability etc.) and the strength of using the larger IT market forces – Cat-5 cable for instance is a lot cheaper than Coax as far more of it is produced.

Again this all comes down to planning the correct system and either utilising new technologies to their best advantage or understanding how best to migrate existing infrastructure to meet the end users needs for functionality, future proofing and budget.

IP CCTV can deliver huge benefits over analogue systems

June 24, 2009

Here are some reasons why….

Improved video quality
IP CCTV solutions support far greater image quality through Megapixel and High Density (HD) technologies that deliver higher frame rates. This enables CCTV to be of high enough quality to clearly capture an incident in progress and therefore identify the persons involved and if necessary bring in law enforcement agencies in order to prosecute with confidence.

Future Proofing
By deploying an IP CCTV solution future proofing can be achieved by enabling integration and support for new technologies and applications such as H.264, HD, Megapixel cameras, proximity access control and identification, Video Analytics, Facial Recognition and Automatic Number Plate Recognition (ANPR). Integration with these technologies enables CCTV to be extended to provide an additional level of security for traffic monitoring, parking, and access control applications.

Linking CCTV with Access Control technology can deliver real benefits. For example in a school a single card could be used for students and staff for access to secure areas, library card identification, time and attendance records and cashless vending. CCTV images can be linked to Access Control records so that in the event of crimes such as vandalism, pilfering or identity theft rather than simply having a database you have a visual image to quickly identify if the access records are correct and also avoid any rebuttal from potential suspects.

Secure access remote access enables an IP based solution to be monitored from anywhere not just in a central control room. Using the integrated intelligence of IP based solutions automated audio response and alarm escalation out of hours can also be achieved as well as incorporation of help points and streaming video to mobile phones.

Cost savings
• IP based surveillance typically has a lower total cost of ownership than traditional CCTV due to the application of recent technological advances.

• CAT 5 structured cabling reduces installation costs.

• Taking advantage of PoE technology means fewer cables need to be run to cameras than traditional cabling and resilience can be increased through the use of Uninterruptable Power Supplies (UPS).

• Latest recording compression standards such as H.264 also provide a saving of up to 75% capacity over traditional analogue solutions whilst maintaining high quality video recordings.
