Motion Detection through glass window?

Motion Detection through glass window?

Postby Philh » Tue Jul 15, 2008 6:51 am

Will an IP Camera such as then Y-CAM Black IP Detect motion outside when it is behind a window inside?

thanks,
Philh

It will during the day but at night, with the infrared LEDs on it won't see anything out of the window due to the reflection.

I have a Y-cam Knight sitting behind a window (while waiting for the external case for it..... hint...hint...nudge...nudge...wink...wink) and I just switch off the LEDs permanently.
At night it can still get a decent image because of the street lights and motion detection is triggered if someone steps into my drive way.

The Knight is in an unused room so it always has a dark background and if I switch on the lights in that room all the camera sees is a reflection off the glas.

Thanks. I am surprised that the motion detection can be triggered form behind glass as thought it might work simlar to PIR house alarms.

Next door are having an extension on the house boundary and will need to come on our land and some point. I want to keep a check on what it happening every now and then especially as our car is parked near it!

So I can place it in the window inside our house...
Any movement of someone coming on to our land will start the motion detection and send snapshot images via ftp?

I can view the camera any time via web page?

The motion detection of IP cameras is based on pixel changes rather than the way PIR work. Although video motion detection produces a lot of false alarms if not set up correctly but it can eaily be used for non-critical applications.

So the answer to your question is yes motion detection should work from beding a window, as long as the camera can see the image you want to monitor.

Yes, I possibly should have added it will work but will require a bit of setting up to work 'effectively'.

Here's a bit more information about motion detection taken from our IP camera Resource Center:

Just bought one of these, and this is what I've found, no view outside through a window, due to the reflections :(

Now, I know I can buy the external housing, but I'd rather keep it inside.

Would an external IR illuminator work, if I turned off the leds on the Y-CAM? A lot cheaper than the external housing, 48 led, 20m range can be had on ebay for £10.

Yes. The camera is sensitive to IR light. Doesn't matter where that comes from it will still pick it up.

The following video shows a recording made with a y-cam black and a separate IR illuminator with 120 IR LEDs. At the y-cam own IR Leds were switched off, also moonlight mode and BW mode was switched off.

It perfectly recorded at a distance of approxmatly 7meters.

The video may not be suitable for work. (surveillance cam at the back wall of our company building)
