Trybrid CCTV?
So, we’ve had analogue, we’ve got IP, now we have HD SDI. With 3 different technologies in CCTV, should we now be looking for “Trybrid” (or “Tribrid”) Surveillance Systems?
Hybrid CCTV Solutions have really helped to grow the Megapixel IP market by offering the customer an upgrade path whereby they keep some (or all) existing analogue cameras and add in new MegaPixel IP Cameras with the increased resolution and coverage they offer.

It’s quite obvious that IP Cameras are here to stay.
The Security Industry has started to embrace the benefits of IP Cameras mainly due to the increased Megapixel resolutions. But although the IT Industry and IT Specific markets have embraced Network Cameras, the Traditional CCTV market has been somewhat slower to take up this new technology.
One major reason for this is legacy coaxial cabling with the need to either run new CAT5/6 cabling or try and utilize existing cabling infrastructures.
ezCCTV now offer an alternative approach with IP Over Coax Converters.
IP Over Coax Solutions
These products are designed perfectly for any existing security installation that has coax cable already in place.
If the customer is looking to upgrade their CCTV System and take advantage of Megapixel IP Camera technology, they can use these Ethernet over Coax solutions to transmit IP Camera video/audio and power over an existing RG59 (or other) coaxial cable.
How IP over Coax Solutions Work
It wasn’t that long ago, that the idea of capturing License Plates and storing them in a database meant spending what most companies would consider to be their entire security budget. Over the past 10 years, the use of these systems has increased dramatically and as technology has improved, the costs of having such a system have come down also.
The process of capturing vehicle plates is often referred to as ANPR (or Automatic Number Plate Recogntion), an ANPR Solution consists of 3 main elements:

I’ve just been playing with the new iPhone client for our surveillance system, powered by GeoVision software!
It’s what you’d expect from an iPhone app; Slick looking with the ability to move your fingers in all directions to flick through your cameras and even move and zoom in your PTZs!

Security Systems and there uses are extremely far reaching nowadays.
CCTV solutions come in a variety of options depending on the budget, features and functionality required and include:
- A basic DVR recording box to capture video to a PC Hard Disk
- A PC Based DVR/NVR with advanced software features e.g. GeoVision
- A DVR/NVR with advanced features e.g. Dedicated Micros
- An IP Camera with built in storage, or connected to a Network Video Recorder (NVR) e.g. AXIS
But one thing that all digital security products have in common is their requirement for Video Compression. Read more…
It’s easy to get confused with the various video resolutions touted by different manufacturers and providers of Digital Surveillance and IP CCTV systems.
And now, with the Mega Pixel resolution IP Cameras becoming more and more common place, it’s more important than ever.
So here’s a quick reference guide which should help:

Wide Dynamic Range cameras have been around for a little while now but although a lot of people have heard of Wide Dynamic, nowhere near as many have actually used this technology.
Firstly, for those of you who do not know what Wide Dynamic Range (or WDR for short) means, here’s a brief explanation…….
Wide Dynamic Range is a technology which allows the camera to cope with extreme lighting levels. This can be very low light but is often used to cope with extremely bright areas such as the sun shining through a glass door or window.
A typical example of where Wide Dynamic Cameras could be used would be where a camera is pointing towards a set of windows. When the sun shines through the windows this can wash out the image and make it almost impossible to view anyone either standing in front of or behind the glass.
As you can see in the example below with WDR technology, the figures in front of the glass and the scene through the glass are both visible.
Example of Wide Dynamic Range
If you are interested in testing a Wide Dynamic Range camera, ezCCTV have a Vandal Proof WDR Dome Camera that is ideal.
