New digital CCTV technology provides many advantages over traditional analogue recording systems. The increased video quality, ability to easily add more cameras to the existing setup, and remote monitoring facilities of a modern CCTV camera kit are great incentives for moving to a digital setup. Here are just some of the reasons why most companies are replacing analogue CCTV systems with digital versions:
- Improved picture quality: Digital CCTV cameras offer far greater resolution and clarity than tape based systems. This can be the difference between recognising a face and letting a criminal get away with no charges. The quality of the picture is measured in megapixels, which is how many dots make up the picture. While you can still find analogue CCTV camera systems that record to a digital recording box, also known as a DVR, these hybrid systems have to convert between analogue to digital and then back again to playback footage. This conversion process can further degrade the picture. With a Digital CCTV camera kit information is always processed in digital form, producing crystal clear images.
- Scalability: It is simple to add further CCTV cameras onto an existing setup. Digital CCTV systems are networked together via network cable, using the same Ethernet cables that computer networks use. This means that there is already an established framework in place for adding and removing camera devices, so adding more is easy. Contrast this with analogue CCTV security systems where each individual camera requires a corresponding cable running back to the monitoring system.
- Remote Access: With networked IP CCTV kit, third party companies can be contracted to keep an eye on the monitored premises. This is very easy to do with the existing equipment in place and would require very little additional hardware. The ability to off source security to an external company drastically cuts costs, since with an analogue system a security guard would have to be employed to sit and watch the monitoring station.
Digital CCTV camera kit offers a great many advantages over older analogue camera systems. By leveraging the power of existing computer network technology it produces higher quality recordings and it will be easy to upgrade in the future. Add to this the fact that monitoring can be sourced out to third party companies cheaply, and you can begin to see why modern CCTV camera kit is here to stay.
