Analogue CCTV upgrade

Recommended Posts

My ageing CCTV which is Geovision 7 camera analogue system installed in 2010 needs an upgrade.

The cable that I have in RG59 siamese with 12 volt.

I have come to learn about DOCSIS and was wondering if the same could be applied for CCTV but locally? so it would use the RG59 to transmit digital signals and use the 12 V for the power.

The wired setup was not easy and I would rather keep the same cables if at all possible.

I want something that has UHD or 4k quality, can that be done.

Also what is the best way to guard against spiders / insects?

 

Many thanks

Hi.    DOCSIS is not needed in your case

keep in mind iP cameras and HD analog (run over coax) give the same performance 

 

using geo 10 years old ….. are you on a pc with cards ?

new equipment you should be looking for is called a 5 in 1 dvr 

and I would install that first with your existing cameras. And then start replacing cameras for HD as and when
