Added new cameras to DVR - How to change resolution

[sammyhw 0]

Hi there,

 

I have a Hikvision Turbo HD DVR DS-7200 series with 6 Northern TVITIR100 cameras hooked up. I bought another two on EBay and had them hooked up today.

When I go to RECORDING CONFIGURATION - MAIN STREAM - SELECT CAMERA - the camera resolution says NTSC with a resolution of 704*480(4CIF) for the two new cameras. The other 6 cameras say 1080P30 with a resolution of 1280*720(HD720P).

 

I'm not sure if I've purchased different cameras to the originals by mistake because the packaging looks identical or am I able to change the resolution because I'm not seeing that option?

 

Any help will be sincerely appreciated.
