Hello everyone

Im new to CCTV and was trying out a DIY install when i came across a problem.

The camera is an ir camera connected to a picolo pro 2 card in my pc.

When i cover the sensor the picture works but during the day, i.e when the sensor detects light it goes fuzzy? Do i have a camera thats not working properly?

Pictures attached of problem.

Sensor covered


sensor open to daylight


Hope i have given all the relevant information. Thanks in advance for any help.

What seems to be the problem?

I have learned a lot about CCTV and other things since I've been on these forums. From what I have learned here, I would most definitely say your camera is "fooked".

Good to know. I thought something was fishy as the personi got it of did not send me a power adaptor at first, had to dispute it to get the adaptor and now that i have tried it, it does not seem to work, can you recommend a decent camera? Has to work well in very very low light conditions.

Its most likely the power supply when you cover the photocell the ir is trying to come on drawing more current and this in turn is dropping the voltage so you lose picture. What current is the PSU rated at? The easiest way to prove this is to put your multimeter across the voltage cover the sensor if the voltage drops then bingo

I'm impressed, you really have been taking things in.

I think it fails when in daylight Pete.

I struggled to work out what he was saying tbh but he said covered the sensor, I took that to mean photocell, which when covered will try to switch on the ir which in turn would draw more current no matter if it was day or night.

Try the camera into your TV, use the yellow av input and repeat the same test. (assuming analog camera)

Sorry for the confusion. The camera has a bnc connection and a power connection. On the front of the camera where the LEDs are their is a little tiny sensor when I cover the sensor with my finger the picture works as in the photo. When I remove my finger and the sensor is exposed to light the picture goes fuzzy. When the camera is put in a dark place and the LEDs activate the image works but when the camera is in daylight the image goes fuzzy see pictures above.

Thanks for the help so far.

IR cut failure?

Thanks. That's all I needed to know. It's knackered

your making it far too complicated, it`s fooked, faulty, knackered.

I know,
But remember, the OP was told this fact last night by our new Guru.

Strange, usually the photocell only controls the LEDs themselves and does not decide when a camera switched from day to night mode.

Before chucking the camera in the bin try it on another screen (like your TV as already suggested), this will rule out any rendering issues with your PC.

Got it!

Do you have with the Pal/ NTCS settings with the card? It may just be that you have it on the wrong setting both settings affect the bars of colour when the picture is mono it will work in either setting. Pal is standard UK but it depends on what the camera is

except the picture of the fan IS in color ......................................

Does look like its in colour but that may just be the tint of the monitor, there is not enough colour in that pic to say 100% its colour

I`ll bet the camera was off ebay.

Do you want some ketchup to go with that chip on your shoulder?

yes it was of ebay. I dont need a proper setup hence the cheap way of doing it. mind you the camera was bought as an ex display but when i got it, it was rusty etc suggesting it was not ex display but a used one, and a non working one at that.
