About HD CCTV

HD CCTV also known as high definition closed circuit television has evolved from broadcast technology developed to bring HD to our TV sets. The main difference between HD CCTV cameras and IP HD is that the Video is transmitted across existing or new coax in an uncompressed format this means that there it is a much purer video signal and one that does not need to be compressed just to send across TCP/IP network. The main benefits of HD CCTV and they way we are able to configure this type of system is that an HD CCTV camera can be plugged into an HD SDI DVR and video can be displayed without latency and and simple set up with no need for any IT training or software. HD CCTV brings all of the benefits of megapixel IP cameras but without the need to complicate and re-cable existing CCTV systems.

The beauty of  HD CCTV is it does not require any additional infrastructure just use the existing analogue CCTV coaxial cable that is already present. This makes it a highly attractive options for any company looking to maintain their investment but still enjoy the added benefits HD CCTV images can bring. HD CCTV is the perfect replacement for existing analogue CCTV and is both forward- and backward- compatible so there is no drawbacks to any company who wishes to enter the HD CCTV market place at their earliest opportunity.
So how much better is HD CCTV than analogue? Well HDcctv cameras deployed at 720P will provide almost three times the video resolution of analog CCTV, and once you use a 1080P camera you can produce six times the image quality. Add to this the fact that all HD CCTV systems are progressive, then we  eliminate any blurring that has in the past been a feature of conventional analogue CCTV systems.

So what are the major benefits of  HD CCTV compared to both analogue and IP CCTV

HD CCTV offers several advantages for the end user, compared to alternative ways of achieving high resolution.

Simple configuration with no training required
Video no longer needs to be compressed and reconstituted at the recording end.
HD CCTV is essentially plug and play and easily fits into existing infrastructure
reliable and robust
Clarity that allows more information to be recorded with less cameras
HD CCTV means no latency
Real-Time Speed Dome Control:
Simple cost effective a true upgrade from analogue without the fuss.

Here at HD CCTV solutions we believe that HD CCTV means upgrades and enhancement for existing analogue CCTV and this fantastic new technology is here to stay is here to stay.

Calsys one of the leading lights of HD SDI technology are currently promoting their latest advanced video platform Zion-HD. The CLS4000-hd series DVR is an excellent example of how HD SDi is starting to take a grip in the CCTV market place. The CLS4008-HD  has the capacity to process 4/8-CH720P+4/8-CH CIF channel encoding and 1-CH HD channel decoding at 30 FPS simultaneously.

The proprietary technology in use here is VClear giving the Calsys CLS4000-HD SDI DVR range one of the lowest encode -decode latency performance in its class. Pre and post alarm recording together with water marked images makes the Calsys HD SDi DVR  a desirable unit for High quality data collection for evidential purposes.

Calsys have put plenty of thought into this HD SDI DVR and its one to consider if HD SDI is your preferred choice of protocol for your HD CCTV installation

WCCTV – Wireless, Rapid Deployable CCTV

Posted on by

One of the interesting finds of IFSEC 2012 was WCCTV

Standing for Wireless CCTV, this UK based company has established a major foothold into the Rapid Deployable CCTV Sector with its range of superb Wireless solutions.

Offering different solutions for differing applications, WCCTV have brought together leading technology from partner manufacturers to provide very unique and individual solutions

One of the VERY neat solutions was the METHANOL powered ‘Tower’ Systems – a liquid fuel powered self contained CCTV Tower, with audio and intruder detection, that can run on silent fuel for upto 6 weeks !!

Utilising the ever popular 360 Vision Predator and transmission from the Xtralis ‘Heitel’ unit, details as follows

WCCTV Standard Tower

Standard Tower

The WCCTV Tower is a complete all in one surveillance solution. The system contains 3G mobile phone technology to allow the transmission of video alarms. It also includes a heavy duty infrared 360 degree pan tilt and 36x zoom camera to allow a remote operator to capture images of any potential intruder and audio speakers to enable a remote challenge to occur. The Tower also comes with a fall back battery in case the power supply is interrupted. Within the system there is a removable hard disc drive which provides evidential quality images for up to 60 days at 25 frames per second. The Tower can also be used in conjunction with external motion and heat detectors. And can easily be linked, if required, to other legacy on site alarming systems

Methods of Power

WCCTV Towers can be powered via mains or generator. Alternatively fuel cell technology can be used, which can power the systems autonomously for up to 8 weeks. When this supply is near depletion, an alarm is triggered to notify the user that there is a requirement to replace the fuel cell cartridge. WCCTV also provides towers which can be totally relliant on wind and solar energy.

Additional Benefits

In addition to providing site security the WCCTV Tower can also be used as a project management and Health and Safety tool. It is possible for office based personnel to access the cameras during working hours and review the recorded images to solve on site problems and/or check regulations are being followed by personnel and sub contractors.

Secure Networks

WCCTV work in partnership with the mobile phone operators provides its own bespoke privately secure networks. These relationships ensure continuity of supply and also provide cell site upgrade and fault information. Working closely with the mobile phone operators enables WCCTV to ensure its equipment is future proofed.

Another of their great offerings is their ‘Site Dome’ based again on the 360 Vision Black Hawk range

WCCTV 3G Site Dome

Site dome

The new WCCTV 3G Site Dome is an all-in-one mobile site solution containing a camera, 3G & Wifi transmission, detection, a tannoy system and evidential video recording. It is a unique product which, coupled with alarm based monitoring and response, ensures that your site is protected. The portable site dome can be moved around your site to meet your changing needs. It is rapidly deployable and has a universal bracket to allow swift installation to any pole, column or building. The Site Dome can be powered using 110-240 volts AC from the mains supply or 12 volts DC with a 2 hour internal battery pack.

Methods of Transmission

Every WCCTV product contains 3G HSUPA mobile technology , plus an additional transmission medium to maximise flexibility and portability. This unique approach provides the ability to transmit fluid, high-resolution images wirelessly without geographical restrictions, making it truly redeployable.

Each WCCTV system has an IP address allowing it to utilise broadband technology, which offers high-speed, fixed-cost transmission networks for live 24/7 monitoring. Broadband technology is ideal for remote surveillance operations where there is access to a telephone line with broadband connection.

The WCCTV 3G Site Dome can alternatively also be operated on private networks as a LAN-only option.

The Wireless Dome system has Wi-Fi technology built in as standard, which enables cost-free, high speed downloads up to 100m away from a Wi-Fi enabled laptop. As an optional extra it is possible to request long range Wi- Fi, which enables cost-free live monitoring up to 2km (line-of-sight) away from a broadband access point.

Features & Benefits

  • Primarly designed for use in protecting and monitoring construction sites
  • Equipped with a radio receiver enabling up to 8 wireless detectors to be connected to provide an invisible perimeter
  • Backup battery system is charging whilst the site dome is powered and is activated if power is disconnected
  • Alarm is raised on power disconnectionRemote access to live and recorded digital footage
  • 3G HSUPA, WiFi and IP connectivity
  • Unlicensed software, unlimited users at no additional cost

Its worth taking a look over at their Website as we believe Rapid Deployment, particularly in temporary applications such as construction, festivals, demonstrations and also street concerns as seen last year in the riots, will involve more and more of this type of innovative tech !

take a look !!
