fenderman 0 Posted October 5, 2013 ip, way more options. SDI is very limited and more expensive. Unless you have problems running new Ethernet cable, go with ip. Share this post Link to post Share on other sites
Robin2 0 Posted October 5, 2013 ip, way more options. SDI is very limited and more expensive. Unless you have problems running new Ethernet cable, go with ip.I agree with this but regarding stability it always amazes me how stable and trouble-free analog runs in use compared to IP.

msecure 0 Posted October 5, 2013 Im thinking of upgrading my analog cctv system and im wondering which is the best to go for IP or HD SDI?what do you guys think ? If you have existing coaxial runs, SDI is the way to go. Most people have a misconception that SDI is more expensive than IP, including myself until just a couple of months ago.

GrouchoBoucho 0 Posted October 5, 2013 Im thinking of upgrading my analog cctv system and im wondering which is the best to go for IP or HD SDI?what do you guys think ? If you have existing coaxial runs, SDI is the way to go. assuming your old cable isn't crappy or damaged... and assuming it's actual rg59/rg6 coax rather than the little thin all-in-one bundle that came with your old costco kit.

icom102 0 Posted October 5, 2013 well it would not be a problem to run new cable is there any difference in the picture quality has anyone got picture samples? ? Share this post Link to post Share on other sites
thewireguys 3 Posted October 5, 2013 If live viewing is important the HD-SDI is the way to go. Uncompressed zero latency video. Otherwise once the images are compressed they are basically the same Share this post Link to post Share on other sites
Robin2 0 Posted October 5, 2013 What IP systems are you using that are not stable?Coax is a seperate system. IP tends to be integrated with other (data / voice) communication. If changes to the IP system are made the CCTV is temporarily out or problems can arise from changes made because of changes or additions in data or voip connections. Multipurpose use of IP can lead to timing or capacity issues. I witness that sometimes an IP camera connection can get disconnected, only to reconnect seconds or minutes later. If you have a separate system to collect and store CCTV that can be an advantage. Share this post Link to post Share on other sites

luckyfella 0 Posted October 5, 2013 I haven't priced them recently, but last I checked, hd-sdi cameras and the DVR were slightly more money than an NVR and IP cameras of the same brand. At least you can use the old power supplies if your upgrading an old analog system though. Share this post Link to post Share on other sites

msecure 0 Posted October 6, 2013 My cctv guy says no matter what i use i wont get great night time viewing with out having to install lighting hay does cameras have irs if you need to put in lighting to light the place up Well, he is right in a certain kind of way, if you have good lightings when your HD camera capture the events, it will be in color. If not you will only see black & white like this. Share this post Link to post Share on other sites

msecure 0 Posted October 6, 2013 Ok finally heres stills from my current cctv cam one is the only camera that has Irswhats your opions? How long has this camera been install? It will have some improvement if you clean up the glass a bit. Also, cam 2, 3 & 4 is pointing at a light source at night so might need to be re-position. Definitely if you change to SDI or IPC IR @1080p it will be 4 times better. Share this post Link to post Share on other sites
