The Difference between Analogue and IP Cameras and What Benefits can you Expect

By | News | No Comments

CCTV provides a whole range of benefits to those who use it. Firstly, and most obviously, CCTV systems deter crime. If a burglar spots a CCTV camera, then the chances of them committing the crime will decrease. CCTV protects your home and business 24/7, 365 days a year. Giving you peace of mind and video evidence in the event an incident happened at your home or business.

If you are thinking about installing a new CCTV system, then you may need to decide between an IP or analogue video format. In this blog, we will help explain the differences between the two systems.

Analogue cameras

These types of systems transfer video signals in an analogue form, usually using coaxial for the cabling, the video will then be recorded on to a DVR/ Digital Video Recorder, every single camera is directly connected to the DVR unit.

IP video cameras

These types of systems broadcast their video as a digital stream; this is over a network unlike an analogue system, the video will then be recorded onto the hard drives, but because the video is an IP stream straight from the security camera, there is much more flexibility as to how and where that video is recorded. The DVR is replaced with an NVR/ Network video recorder, which in some instances is just software based since it doesn’t need to convert analogue to digital.

So what are the benefits? What can you expect when using IP Cameras over Analogue CCTV?

Unlike a few years ago, where cameras have poor video resolution, now we full 4K HD IP cameras that totally outmatch any analogue camera solution. The higher pixel resolution of the IP cameras means you can zoom into the video itself, it will then reveal much more detail of a particular scene/event or even a persons face, even after it has been recorded without losing any clarity of the video.

All analogue video cameras use the NTSC analogue video standard, which was created in the late 1950s. No matter what manufacturers claim, the image quality is being transmitted and recorded using this standard. Many find it hard to believe, but a simple IP video security systems are very cost effective to install and easy to operate.

Today, most IP cameras are plug in and go, In the same way, your computer’s webcams will.

The amount of cabling needed is reduced too, IP cameras use a single cable that can be used for everything, Using Power over Ethernet, PoE,, IP security cameras can be powered through the same cable that transmits the video signal and any PTZ commands, Pan, Tilt, Zoom.

Whereas an analogue security camera, have a single cable that can only transmit its video signal, these types of cameras also require a separate 12v power supply installed ideally local to the camera using a different cable, and if you want added functionality such as PTZ controls for the camera, you’ll need another additional cable for that.
