hello forum i have i little problem i need help with (i do not need a cctv snobs view please do not be offened by me saying that) what i need to know is cctvcameras come in different tvl i know dvr recorders can only record at a a certain level (i use a kodicom dvr card) so i do not want to buy cameras that are over spec costing me money what do not do any justice to play back.

the next question is is there a great difference from sharp chips and sony chip (exsept for the cost) will a customer notice

many thanks forum

any help at all would be great

eddie

My understanding of it is there is no direct relation between the TVL of the camera and the level (FPS or IPS) of the DVR card. What I mean is if you use a higher spec camera, the playback images will be relevant to the camera. A 700TVL camera will produce a considerably better picture than a 280 TVL camera, regardless of the recorder. Obviously a 100FPS DVR card will produce 'better' (more) images than a 50FPS DVR card during playback.

TVL may be better thought of as resolution.

The 'level' (FPS/IPS) of your DVR is purely how many images it can record per second.

Couldn't really comment on your second question, although, unless one was more prone to failure than the other, I doubt the customer would notice.

i have connect to my dvr recorder (kodicom) 570 tvl nightvision camera

and a 480 tvl camera the picture i get on live screen and play back is exactly the same apart from the other camera costing me another hundred quid so what i am asking is if any one uses the kodicom system what tvl cameras do you use and are happy with .

ok

to put it another way for a standard shop 4/8 camers int what cameras would you recormend (tvl) kodicom dvr

what do the puplic find acceptable

for a standard install shop small outlet

480TVL seems acceptable to me. Really depends on how good a picture you want!

Panasonic and JVC are well regarded.

Hi eddie

You will find the better the tvl of the camera the better the picture the other end.

Of course you are limitted by the cards resolution but if you put cr#p in you get cr#p out.

THANKS FOR YOU RELYS

THE ONLY RESON I HAVE POSTED IS I HAVE JUST REPLACED X4 CUTOMERS CAMERAS FROM 480 TVL TO 570 TVL AND TO BE HONEST I FEEL LIKE I HAVE RIPPED THE CUSTOMER OFF BECAUSE THERE DOES NOT SEEM TO BE MUCH DIFFERENCE IN THE QUALITY OF PICTURE. I SPOKE TO THE SUPPLIER OF THE KODICOM CARD AND HE SAYS THE CARD HAS ITS LIMMITS BUT IT IS ALLWAYS BETTER TO BUT MORE IN THAN LESS IN THAT TAKES ME BACK TO WHY PAY MORE FOR MORE TVL IF DVR RECORDER CANNOT REPRODUCE IT

SORRY TO BORE YOU WITH THIS PROBLEM

PLEASE UNDERSTAND

THANKS AGAIN EDDIE

Thats strange as I have one of those cheap nasty pico cards in my house(I dont need h quality) and when I upgraded from 380 line to day/night 480/520 lines it made a noticeable difference.

At work we dont use cheap cameras if we can help it at all.

Pete

It will also depend on the amount TVL that the DVR card can reproduce on the screen/monitor and the TVL of the screen/monitor itself.

I assume it's being viewed on a PC monitor, if so try increasing the monitors resolution. ie. from 800x600 to 1024x768

thanks m8

i will try in the morning

thanks to you all
