The use of modern digital recording systems for your CCTV footage provides several benefits over the now outdated method of recording to a video tape; including greater storage capacity (usually within a smaller footprint unit), the ability to conduct quicker and easier searches for specific footage and the potential for remote monitoring, amongst others.

Whether you choose to record footage using a DVR (Digital Video Recorder), NVR (Network Video Recorder) or the cloud, the benefits and functionality of digital recording far outweigh earlier, analogue methods of storing and handling CCTV footage – so much so that digital recording has now become the norm.

Choosing from the available range of specifications and capabilities of modern digital recording devices is probably equally, if not more important than the specification of the cameras linked to them; so it is important to establish exactly what you want and need the digital recorder to do before deciding upon the best solution for you.

One of the most important considerations when designing a digital recording system is the storage capacity, as this is influenced by several factors including:

  • The number of CCTV cameras connected to it
  • The frame rate (image capture rate) of the CCTV cameras
  • The image quality that the connected CCTV cameras are capable of
  • The number of days a week and hours a day that you want to record
  • The amount of footage you want to have available on the recorder at any one time (as the devices typically record on a FIFO (First In First Out) basis to maintain a rolling video archive)
  • Any  image compression standard used on both the cameras and the digital recording device

Beyond this, some of the other important considerations when choosing a digital recording solution include:

  • The recording resolution – (higher resolution recorders will provide better quality on playback)
  • The ability to easily and securely copy and transfer large volumes of data (footage) – (so that it can be used as acceptable evidence in the event of an incident)
  • Whether you require to remotely access your camera footage via the internet
  • The video compression capabilities of the Digital recording device which can help you make the most of the available storage capacity without compromising the image quality.
  • The built in analytics and / or advanced search facilities – allowing for huge amounts of digital recordings (sometimes covering some months) to be very quickly scanned to find the required footage
  • The build quality of the digital recording device itself; and for it to have features which will ensure system integrity – even in the unlikely event of any of the components failing
  • Whether you require optimum resiliency in the storage of your digital recording, whereby you may also want to consider the use of an additional back up drive. This would mean that in the rare event of a digital recording device failing; then the back up drive would automatically take over the recording responsibilities until a replacement for the primary drive is installed.

To ensure that you have the most appropriate digital recording solution to suit your site requirements and budget; we offer a comprehensive range of systems and device capabilities from an almost equally wide range of manufacturers.
