westy1 Posted January 21, 2017 Share Posted January 21, 2017 Just wondered if HD-SDI CCTV production had now completely ceased. I know it is harder and harder to source DVR's and cameras but just wanted to know if anyone had any definitive knowledge..?

sixwheeledbeast Posted January 21, 2017 Share Posted January 21, 2017 It has gone out of favour in the CCTV industry. Most distributors are switching from SDI to CVI or AHD models. It's a shame it's a good transmission method and used widely in the film industry with current standards supporting upto UHD resolutions. With limited DVR compatibility, higher price and low transmission distance it would seem costs have driven the market to more lossy formats. The future is IP. If the price is right I can see PoE EoC becoming popular for those jobs that require it.

If the price is right I can see PoE EoC becoming popular for those jobs that require it. I have installed IP but in when a customer wants installation over coax I am leaning towards HD-CVI now. I use two distributors in the UK and there are not so many limitations with it. Do you think HD-CVI will be phased out in favor of IP?

westy1 Posted January 22, 2017 Author Share Posted January 22, 2017 I have to believe there is a future for coax based CCTV because anyone upgrading to HD now can generally use their existing coax cable network (subject to not been a poor grade of cable). This obviously saves on time, cable costs and install costs which is a win win for customers and helps keep the quotes down.

sixwheeledbeast Posted January 22, 2017 Share Posted January 22, 2017 It's possible but all down to cost. If too expensive with no extra benefit it will not be worth it, therefore suffering the fate of SDI or not even getting to production.

datadiffusion Posted January 23, 2017 Share Posted January 23, 2017 Ironically the crappest analogue CCTV jobs usually use (albeit CCA) Cat5 anyway so it's at least future proof! So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment https://www.thesecurityinstaller.co.uk/community/topic/40860-has-hd-sdi-production-stopped-all-together/#findComment-457248 Share on other sites More sharing options...
