Guest scramble Posted May 12, 2013 Report Share Posted May 12, 2013 take your rig off the scope and see what results you get. Quote Link to post Share on other sites

weebster 17 Posted May 12, 2013 Report Share Posted May 12, 2013 (edited) look's like this one http://www.securitycamera2000.com/products/420TVL-SHARP-CCD-Color-Board-Camera-3.6mm-Lens-10m-IR.html If it is the same cam it has a 1/4 ccd sensor,no use for nv as it's to small. Have you disabled the ir diodes on the board? Has it got a filter in front of the ccd?...some colour cams have,although it claims to be for night use so it shouldn't have. Have you got the nm800ir on full power setting?....the cam might not be sensitive enough to detect ir light on the lower/middle setting of the 800ir Some have used these cams with good effect http://www.securitycamera2000.com/products/540TVL-HD-Mini-CCD-Camera-MIC-Low-Illumination-0.005Lux-4mm-Lens.html http://www.securitycamera2000.com/products/540TVL-HD-Mini-SONY-CCD-Pin%252dhole-Camera-MIC-0.01Lux-9%252d22mm-Lens.html Edited May 12, 2013 by weebster Quote Link to post Share on other sites
Russ1986 1 Posted May 12, 2013 Author Report Share Posted May 12, 2013 Yes the leds are disconnected. Insee on your one it says it has a 10m range. Thats not the problem is it? I am using a nm800 IR with the camera. No it doesnt have a filter. Will have to look into that cams. Only wanted to get the thong working cheap to see if i could make it first then was going to upgrade to a watec camera. Quote Link to post Share on other sites

I expect the 10m range refers to the ir leds on the board,which is about right for those kind of ir leds The night master should work very well with it. Although you may suffer blooming (white out) using it with a 902h....in fact you will suffer blooming with the 902h with most led ir at some point due to the camera being sensitive. What range are you shooting to? Did you buy the nm800ir from new? Edited May 12, 2013 by weebster Quote Link to post Share on other sites
Russ1986 1 Posted May 12, 2013 Author Report Share Posted May 12, 2013 Yes i got it new. Oh so they maybe are not the cameras for me then. Most of the foxes and rabbits round where i shoot are very lamp shy. So i was going to try and make a night vision as i had a ns200 but it wasnt up to the money was very bad picture and thought i could make better but it seems not. (Bugger) Am not sure what distance am looking for the further the better for spotting then try calling them in. As there will be no light it will be easier i would think.

weebster 17 Posted May 12, 2013 Report Share Posted May 12, 2013 Your probably better off getting the watec 902h then rather than chuck money around on cheap board cams. Unfortunately the price has gone right up on the 902h,last time I looked they were well over the £100 mark. Quote Link to post Share on other sites
GEOFF.223 83 Posted May 13, 2013 Report Share Posted May 13, 2013 Is the ir filter been taken off the camera and is your lens a filter free one? Quote Link to post Share on other sites
ghillies 209 Posted May 13, 2013 Report Share Posted May 13, 2013 two points i can think of are, geofs sugestion, some lenses are built to block IR, on most of them lenses thers a red ilter at one end or the other, or when you look through the lens on its own you'll see redish in it. tuther is is your light IR filtered, as in its narmal light with a IR filter on? if so and its an LED, dunt matter how briht there'll be naff all IR coming off of it.

Russ,have a look at the sensor with the lens removed,hold it at a slight angle and see if there is a redish hue to the glass over the filter,it might have a filter. Also check the 800ir is on top power setting,you should get good enough results from a 1/3 ccd cam especially with the 800ir torch. Chances are that board cam has a 1/4 ccd which isn't really upto the job,it might also not be as sensitive to 850nm ir light as some others are. Quote Link to post Share on other sites
