Show your existing CCTV some Love Posted on 10th June 2013 by Terry Simmons

Show your existing CCTV some Love

Technology is changing on what feels like an hourly basis these days and you only have to go on holiday for a fortnight to miss the latest greatest new peice of hardware released before it is superceeded the following week. Despite it changing so rapidly it doesn't stop our (and my own) desire for wanting it that very moment. It doesn't matter if this is a phone, laptop or a CCTV system. The one thing that stops most of us is the cost associated to a shiny new peice of tech.

High definition IP CCTV is desirable but can also be essential to your home or business and with the development of high resolution chips for IP CCTV the difference between installing an analogue or a HD camera could be the difference between a prosecution or a case being thrown out of court for insufficient evidence namely being unable to identify due to poor quality CCTV.


As nice as it would be to install a shiny new IP 1080p+ system the budget may not be available especially in this economic climate. However, there are a number of options that can utilise your existing analogue cameras and infrastructure meaning a cost saving and giving you high resolution cameras in key areas whilst future proofing your system at the same time.

Hybrid DVR – By installing a Hybrid DVR you will have the option to install both analogue and IP cameras onto one system. I would recommend looking at the PC based Hybrids as these will allow you redistribute the processing power of the unit so as you remove more analogue cameras in the future you can replace these with IP cameras in varying resolutions. There are a number of more cost effective hybrid DVRs that allow a mixture of analogue and IP cameras but these tend to be fixed values i.e. 16 analogue and 2 IP cameras. These can be ideal if you just want a couple of IP cameras and have no plans for further development.

Software Solution – Software supplied by external development houses for CCTV pride themselves on being able to work with multiple manufacturers’ recorders and IP cameras. This option would mean that the existing DVR (providing compatible) could be included onto a software program which then takes other manufacturers IP cameras and brings them together onto a unified platform. This could also work the same if the manufacturer of the DVR(s) also manufacturers IP cameras. This type of set up is ideal for multi-site companies looking to monitor all their sites from one platform or large enterprise deployments.

Encoders – The majority of IP only manufacturers have encoders available. An encoder is normally a single or 4 channel device that takes a raw analogue video signal and processes it to an IP signal compatible with their own software or NVR. This means that if a particular manufacturer was selected then you could use banks of their encoders to replace DVR’s and then network the signal back to the NVR or recording server. This is ideal if you want all administration from a central point.

The next hurdle to overcome is the cabling back from existing cameras on coax and there are only really two options. The first is to install a converter that allows IP data to be transmitted down a traditional coaxial cable. These are ideal where it is not physically possible to replace cables or when the cable run exceeds 95 metres. The other advantage to these convertors is you can covert one coaxial cable and run up to 4 IP cameras back to your recording platform. The second option is to replace the coaxial for Cat5e/6.
