Johnny Posted March 24, 2009 Posted March 24, 2009 Just fitted one of these, its a budget Dvr from Alarm Supplies. Its only a one camera job, picture on the camera is perfect but when connected through the dvr its not so good as if it needs terminating. Its was late tonight while trying to finish the job an need to attend again this week....... Anyone used these.
y-i-out-of-bed Posted March 24, 2009 Posted March 24, 2009 if you have a test mon put it between the two and see if video drops when you pluged in dvr, if it dose could be dying camera or dvr ch fault, try difrent load for camera eg big mon/tv and see if same happens if this is poor video then camera or ground loop fault or cable at fault, if no help try pluging in sky/freeview box or spare camera to the dvr and see if same happens with the new feed, if it is a ground loop problem a humbug could crack it, also i know this is basic have you belled out cable? eg shorts including above kohm or shorts to earth? also is voltage at the camra ok? dying camra or low power camera can look as though bad termination just not got power to drive dvr but would look ok on test mon, hope this helps though feel im pounting out the usual but maby it helps to see from fresh eyes though unit dose look very basic
Johnny Posted March 25, 2009 Author Posted March 25, 2009 Well Ive just tried the unit at home on a 22 in tv and works fine. The picture loose's the quality a touch but not really noticable. So my thoughts are the customers tv as its a 50 in screen. Anyone else had this?????
james.wilson Posted March 25, 2009 Posted March 25, 2009 so he has an expensive 50" screen and a cheap nasty dvr? securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
Johnny Posted March 25, 2009 Author Posted March 25, 2009 His own choice as its small and doesnt make any noise Thanks for your help.......................
breff Posted March 25, 2009 Posted March 25, 2009 That DVR I suspect will record in CIF format at best which is 352X288 and you are scaling it up to try to fit a screen that is 1920x1080 and 50 inches diagonal, that is going to make any camera look //.B.W.F.//. The opinions I express are mine and are usually correct! (Except when I'm wrong)(which I'm not)
james.wilson Posted March 25, 2009 Posted March 25, 2009 His own choice as its small and doesnt make any noise Thanks for your help....................... his choice? oh well his problem then but as above even a good pal camera aint gonna look great blown up that big. Id say he needs some high def cctv. securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
A-G Posted March 25, 2009 Posted March 25, 2009 If it's just a one camera job, the live view doesn't need to go through the DVR. Don't know if that info. will help you. . . . PM me for access to the SSAIB members discussion area.
Johnny Posted March 25, 2009 Author Posted March 25, 2009 He has a GJD pir on the front door so when it bleeps he can turn to the av channel and view. When I put images to the usb then to the laptop it not great but ok for a cheap system. Here is a pic. The camera is not in the correct position yet ............
