Dear All,

Please could I have some advice on the following, I'm new to CCTV and the below is a proposed setup by a crane supplier:

We have 4 x 700 TVL Cameras being fed into an Axis 4 Channel Encoder which supports max resolution of D1 at 15fps per stream.

I need to stream these in a quad view on a 27" Dell 1080p monitor.

My question is what is the best setup for these:

Do I adjust the monitor resolution and aspect ratio so that the streams are not stretched? As a 1920x1080 resolution monitor split into 4 would be approx. 960 x 540, whereas the D1 resolution is 720 x 480

I am a little lost as to how to set this out, I'm sure you experts will laugh and give me a simple answer to make this setup most effective with the best quality possible with what hardware I have to play with.

Good to make note that the 4 x 700 TVL analogue cameras are not changeable as per the agreed specification. Therefore what I have is what I have got to play with.

Any help would be extremely appreciated.

Thank you all in advance.

If you have PC, you can install VLC, open the RTSP stream of Encoder, you didn't provide model, example:
https://www.axis.com/files/manuals/um_m7014_54168_en_1310.pdf
Code:
rtsp://<ip>/axis-media/media.amp


Change the Aspect Ratio in player.

You can make a shortcut for simple access
Code:
"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" rtsp://<ip>/axis-media/media.amp --aspect-ratio 3:5


P.S.
Check that RTSP is enabled under System Options > Network > TCP/IP > Advanced

P.P.S.
If you won't find RTSP string, you can try this method:
