Yeah, only way to go IMO with the exception of a better IP camera that can have something like that running in it with the bit of the image monitored settable in the same way and with a decent logic sequence in software that's the only way to eliminate false triggering properly. Its mad to be farting around with a separate PIR and masking tape instead. |

Are the contacts "voltage free"? I suspect that 24v DC is the maxium rating they can switch rather than there being 24v present. What is the camera expecting? Just a switch/contact closure across a couple of terminals/pins or a voltage? If a voltage that is almsot certainly going to be available from the camera. (*) Yes, it could have DC-DC convertor but not very likely in a PIR. -- Cheers Dave. |

Actually, RodHead has it right. My ActiveWebcam software on the PC will detect motion within any user-specified perimeter on the video frame. Makes no difference what type of camera it is. steady on grimly ;) yeah I have no doubt that software running 24/7 on a PC analysisng video feeds from anywhere would allow lots of "precision" titting about and setting up. But that's not why I went the IP cams route, I went IP cams to avoid having to rely on a (in my case) old windows PC running 24/7, relying on it rebooting itself properly after a power cut etc etc etc. The cams themselves (nearly) do all the work - just this one that needs help detecting genuine "events" PIR will do nicely just a shurely shimple? lash up needed to test the theory and then implement? So which relay do I need? Anyone? (well you know almost anyone ;)) Jim K Screwfix's stock may have changed but I have two situations where I have 240v PIR's from them operating parallel switches on to standard PIR lights - and the relay contacts in the standalone PIR's are volts free. mmm thanks for that - do yours have a "make" &or "model"? do SF's or Toolsatan's current stock look like yours? I've just bought a 12vdc alarm quad PIR (as suggested earlier in the thread), seems I'll be back as the spec says "alarm" will output 24vdc yet the IP camera I/O is rated at 5vdc ;# If Screwfix don't stock them now, then I'm sure there will be something on the Bay. I doubt the average ebay vendor would have a clue what I was asking them ;) Jim K Jim - the SF current offering (#11291) looks very much like the two I have. The SF website does give access to the instruction sheet which includes a UK customer helpline. Rob |
low voltage PIR trigger setup for IP cctv cam
"Adam Aglionby" wrote in message ... Cops main reaction is concern that karakoe man has CCTV facing onto a public street without signage and a contact number. Well if its a business it gives the lawyers a loophole to use if they are caught. If its just a residence you don't need the signs. Its legal for a private individual to take films and/or photos of *anyone* in a public place. |

The camera input will probably be a pair pulled up to 5V via an internal resistor that you can short to make it switch. Shame you aren't reading what I say anymore. |

I never said anything about them having cctv, just about posting it on the internet. The law is quite clear, you can take pictures and videos of anyone, but it restricts what you can do with them. |

getting Pd off with motion detecing IP cams sending 100s of emails of moving bushes and sunshine/shade changes. One of the IP cams has 2 channels for I/O - so I'm pondering how to send a signal to it to take a snap when something goes across the cam;s field of view. PIR would be perfect but a very narrow "beam" is required to make sure I get the subject in the centre of the frame... and the IP cam is not going to be happy with 240v up its I/O - so ??? low voltage PIR? what from where? Somewhere which sells parts for intruder/burglar alarms would be the obvious place to start looking. Most likely the 240v unit actually consists of a relay, cheap PSU and a low voltage unit anyway. |
