Ohh ... I am Sorry. Off course for Network Camera's we Go for Category 5 or 6 cables.

ok ! Thanks every one.

thx for replying. But that camera says "30 fps real time recording" so why are you saying 15 fps? what does it mean by real time recording? the internet of 4.1 Mbps that u mentioned is that download or upload? I am planning to buy this internet package: http://img546.imageshack.us/img546/1950/7owh.jpg As you can see download is 30 Mbps and upload is 5 Mbps As Internet is intended to see camera's at a centeralized point , and both a camera and the CMS (centerallized management system) is connected to a Router that is supplying internet services. hence Uploads and Downloads are seen with respect to that Router. HD Camera ---->> DVR ---->> Router ----->> CMS. (Download) HD camera <<----- DVR <<---- Router <<----- CMS (Upload) you need better download then upload . (PTZ cameras also require up load to send signals to PTZ cameras) >> when you access resources from a server (say DVR) then you are downloading from Router. >> When you request resources from DVR , (when you open browser or CMS to see video) then you are uploading to the router. First : Real time means the rate at which camera is seeing the scene , we are also seeing at the same rate. that is 30 Frames per second (Fps). but at this rate we require more bandwidth. and if you are also recording at the same rate then require more HDD space. Two terms are common. 1 - Record at low FPS say 15 fps or even less. 2 - see at real time 30 fps Humen eye can not detect jitter (pausing of video) greater then 18 fps . and at 5 fps is some cases you can get all the details that are necessary for forensic investigations. there are standards to use destined FPS for different cases , e.g for casinos 30 fps Record 30 fps View that means real time record and view (monitor) for stadiums 1 fps for schools 5 fps etc.

what is the reason of this? HD camera contains more detail , hence has more bandwidth . Bandwidth capacity of RG6 is greater then RG59. i mean you can get more details on RG6 then on RG59 cable. another and most important reason is that after every 100m of cable run RG59 signal degradation is 8.7 db . and for RG6 it is 6.4 db. This means that RG6 can beter cop with outer noise. 3rd due to better copping capability with noise ; RG6 can be layed at larger distances upto 1500 meters in single run (1000 / 1200 m is recommended) , on the other hand RG59 can maximum run upto 700 m recommended.

and one more suggestion , use RG6 cable with HD camera's , dont use RG59 cable that is commonly applied to CCTV systems.

There are many Bandwidth calculators available on internert . search for "HD camera bandwidth calculators" or Try this one . http://www.stardot.com/bandwidth-and-storage-calculator as For you need , 1 of this camera at 15 FPS will consume 4.1 Mbps. you need an internet connection of 4.1 Mbps or Above . normally it would be available as 6Mbps.

It has "okddns.com" , "bestddns.com" etc. would these work ; if i use them "only". i mean if i dont use routers ddns service. and only use ddns present in DVR , will the DVR inform dns server when ip address of router changes ?

sure the DVR has ddns services , i have tested it with other Routers.

The Router is Mobily4Gconnect . in its DDNS configuration there is no other option to select other then "dyndns.org" . which is not free anymore. neither the router is giving any options to add custom DDNS service of another server. you can see in the Attached image. i want to add other services to ; Remote View the System. I dont want to get a static IP from ISP. Any Clue or Suggestions. Please Help. Thanks.
