Recomendations for CCTV kit?
Hi,
Owing to ongoing hassle with the next door nutty neighbour (we've just had trees entirely in both our front and back garden vandalised by him) I'm looking to splash about £300-400 on four cameras and a hard drive based recorder. Police can't take any action otherwise ;-( http://cgi.ebay.co.uk/290438777726 Looks interesting - the domes will mount under the eaves of the roof, though I've heard comments that 1/3" is a better bet than 1/4" for the cameras. Only interested in wired systems. Though looking at the above kit, I'm now wondering about D-I-Y rolling my own with a security DVR card, cameras and a server box. So if anyone has done that with cards similar to http://www.camsecure.co.uk/CamsecureBT878aPCICard.html ?? -- Adrian C |

Yes, it's an invasion of privacy, but not illegal for non-businesses. from http://www.ico.gov.uk/Global/faqs/da...he_public.aspx "Q: My neighbour has installed a CCTV camera and it is pointing towards my house/garden. Is this a breach of the Data Protection Act? If your neighbour’s camera is installed on their residential property and being used for their own personal domestic use, they are unlikely to be breaching the Data Protection Act. This is because the use of CCTV cameras for domestic security purposes is exempt from the data protection principles. This applies when a person uses CCTV to protect their home from burglary, even if the camera overlooks the street or other areas near their home." -- Adrian C |

You just have to be carefull about what you record. Top tip, do not let your neighbours know about the cameras until they have put their foot in it. Covert is very good and audio is even better.

A few thoughts, as you have said 1/3" would be better, not essential though. 420 lines is adequate if you have a close up enough picture. That is where my main concern would come with the cameras mentioned here, they only have 3.6mm lenses and as such will give you a wide over view of whatever you are looking at and may not give you enough detail to positively recognise someone. You will recognise them because you know them, but the image you get will be like some of the rather poor shots you sometimes see on the TV news from shop CCTV's. A way around this maybe to use a couple of these cameras for an overview of the front and back garden and then either place one very close to where you expect problems or look for a separate higher spec' camera and lens for the detailed shot. The DVR looks to accept 1VPk to Pk of video so that almost any camera will interface to it. Not all IR LED's are invisible to the human eye so your neighbour may well spot them, could be good as a deterrent, but awkward if it's hidden in a bush and they can get to it. Setting up those cameras can be fun too! A small handheld monitor that you can take up the ladder with you is the best way, but failing that a very patient person at the other end of a mobile phone or radio is a must. Play with them indoors first and make a note, tipex mark or similar on the front, as to where the top of the picture is. They are literally a metal sphere held behind the cover and are "interesting" to physically set up. Before setting them up take a look at the site at night with all possible lighting on and try to find locations where any lights, flood etc. are behind the camera if they are on your property and if they are not under your control then try and set the camera so it cannot see them at night as they will cause the auto iris to close and reduce the sensitivity of the camera. Or they will cause flaring on the image, neither of which are good. All in all the kit that you link to looks to be a good start and should give you reasonable results, don't expect BBC quality though! :-) Hope some of that made sense? Best of luck with your problem. Have fun........ -- Bill |

Adam Audio is VERY much better! Especially if you have a conversation with your neighbour within site of the cameras. I know a site where although it was very well covered by CCTV the security guards also wore radio mics so that any conversation with "people" at the gate was recorded along with the CCTV so that there was no argument over what the images portrayed. -- Bill |

I will soon be upgrading my CCTV and I am looking as spending over £1000 to get better pictures. Most of the cost is on the recorder and I will add cameras when I have the money. Adam |

Even if its an analogue recorder the quality difference between a £200 one and a £1000 is not a lot. Maybe you just want 32 channels? |

One downside to my old DVR card is that it (apparently) uses video overlay and LogMeIn won't display the video when I log in remotely. In my humble opinion I reckon the quality of the cameras is the important thing. Most of my cameras aren't too good at seeing detail at a distance. I'm hoping for a recommendation for a good camera at a reasonable price. Maybe someone here might be able to help. Regards |

So if anyone has done that with cards similar to http://www.camsecure.co.uk/CamsecureBT878aPCICard.html ?? -- Adrian C Having just done similar security , er, review. Capture cards , unless you get free power forget it, box takes a fair amount of power and unless need some feature that full size PC offers it`s as stable as a blancmange, though if want go that way Zoneminder on a dedicated box offers lot of features http://www.zoneminder.com/ DVRs are cheap as chips and have AV drives fitted, got an AV Tech similar to one you linked to with 500Gb WD AV drive for £160 on ebay,AV drive is guaranteed for 3 years of 24/7 operation, desktop drives overheat. Have 2 with Sharp 1/4" ccds in them , theyr`re OK , one is a door viewer camera that people simply dont notice unless point it out to them, other is outdoor but compact with no IR ring, which alawys glow in dark surroundings. Have a 460TVL 1/3" Sony Super HAD where the quality and sensitivity are a visible notch up from Sharp, stay in colour to very low light levels and excellent low light ability. Vari focal is handy that ones a 4-9mm adjsuted by screwdriver, down at 3.6 mm view angle is probably near 90 degrees. Could also get board lenses and swap out lenses on other cams but its a faff. Connections, either power and video (but no audio) so called `shotgun` cable which is expensive on long runs, or CAT5 Baluns easily go to 200m+, RJ45 socket to BNC , 2.1mm Power and if required Phono Audio, ebay or DX, cheapest found on exterior grade Cat 5 Kenable http://www.kenable.co.uk/ Might need a couple of this to that connectors to avoid chopping plugs, i.e. door viewer cam had video out on phono, Maplins do Phono/ F, to BNC/M in a plug.

Because people think they are good because they are "digital" ? They are just expensive and complicate matters. Nothing beats hardwiring with coax if you can manage it, failing that 600 ohm twisted pair will be more than adequate for any domestic situation. A further thought to the OP is, if you can run all the system from one power point and fit a UPS to cover power loss. If your neighbour is a really devious son of an unmarried mother and realises what you have done he may wait until there is a power cut and then do something bad. -- Bill |

You are better to have 150 watt sensor lights on your property and use cheap video cameras with no lights on them. All you need is one camera with motion detection, then you can look at the other cameras for evidence. You don't have time to watch all the recordings even at fast forward. I recommend lots of hidden cameras. I'm waiting for a guy to come back for a thrd time to steal copper downpipes. There's a new camera two metres away from the downpipe.

You are better to have 150 watt sensor lights Interstingly 120W is the new 150W in small halogen floods, totally agree, cams dont actually need much light but 500W can cause them to iris down missing the in the dark action. on your property and use cheap video cameras with no lights on them. All you need is one camera with motion detection, then you can look at the other cameras for evidence. Other method is to use PIR detector to DVR/PC alarm inputs , Cat5 Baluns with audio jack if not using audio in that channle, have handy connectorised pair and 12V available from cam supply. PIR detector dosen`t have to be beside cam. Cat5 the wonder multirole all terrain cable ;-) You don't have time to watch all the recordings even at fast forward. I recommend lots of hidden cameras. Give them something to look at/aim for and something that watches them watching waht they think is you, cams are small and cheap, sometimes hidden in plain sight is good. Have a PIR tiggered gate guardian cam that alerts me to look at other footage if required. I'm waiting for a guy to come back for a thrd time to steal copper downpipes.

Looked at the cost as another insurance policy but with a cover lifespan of a few years.

"dennis@home" wrote in message ... "ARWadsworth" wrote in message news:wtyMn.10863$8g7.7049@hurricane... The recordings were date and time stamped. The camera that covers my front door gives a good face recording. I will soon be upgrading my CCTV and I am looking as spending over £1000 to get better pictures. Most of the cost is on the recorder and I will add cameras when I have the money. Then you will be wasting the money. IMO it would be better to go down the IP camera route, then the recorder has no bearing on the quality at all. Even if its an analogue recorder the quality difference between a £200 one and a £1000 is not a lot. Maybe you just want 32 channels? I do not want or need 32 channels. What would you record the images with if using an IP camera? It is the playback quality of the recordings that is important when you need to play something back. Adam |

Check this before you buy or install. http://www.nfh.org.uk/resources/Articles/cctv/index.php Peter Crosland some rather obvious "vested interests" in that link.. plus references to "video recorders" and video stored on PCs being "inadmissable evidence" but of course no explanations ??.....seems somewhat out of touch ? Any large CCTV system these days will have hard disk recorders in it. Can't remember the time I last saw a VCR in such a location.. Course most anything on the disk can be put on a CD or if its not that big e-mailed or FTP'd even... -- Tony Sayer |

What would you record the images with if using an IP camera? Computer. Disadvantage: is the computer needs to be running 24/7. Advantage: computer (or a backup) could be in someone else's house streaming up the DSL so the thieves cannot nick it to destroy the evidence of their arrival. It is the playback quality of the recordings that is important when you need to play something back. Yes. It takes a reasonably decent IP camera to get a good still image across all light levels from full sun to security light/IR. It takes an even better (ie expensive) one to manage that in video mode. However, I've had very good results doing still image capture from an Axis camera (several in fact). The camera was motorised with optical zoom, so I was able to drive it to one of 8 preset positions, grab a JPG (and timestamp it) then instruct it to move to the next preset. We managed timelapse at one frame-position per 40 seconds (the camera needed 5 seconds to settle after moving) and the camera was 600 quid, but it was effectively 8 cameras. The image quality was excellent even in the notional dark, as we found when thieves turned up to nick some Apple Macs. If you got a camera of similar optical quality without the zoom/pan it should be a lot cheaper and you'd be able to timelapse at any sensible rate, upto probably 1-2 frames /sec. One advantage if you can check the stuff remotely. -- Tim Watts Hung parliament? Rather have a hanged parliament. |

What sort of technical specification is advisable? I should imagine that a blurry, smeary, B&W shot of some one, (who could be any body) only 1/4 height of the frame has less chance of being of use versus a sharp, defined, colour image even with the same sized figure. Things have improved, but when cameras were fisrt used in football grounds, the B/W pics were far better for ID purposes than the colour. Colour was OK for, well, colour of clothing, but for features and sharpness of image B?W was best. (20 yrs ago FWIW) It's still true today that webcams interpolate colour images as they use a matrix of camera elememts, each sensitive to a particular colour. They're usually grouped in 4's (2x2) so the resolution for shapes is less than the number of pixels the camera has. The good news is that for some webcams, it's possible to reprogram the firmware and get the "raw" pixel images, rather than the interpolated, colour processed picture. Amateur astronomers have developed some sophisticated techniques that will either allow you to get native outputs as seen by the imager, (or will "brick" your camera if you're unlucky, don't follow the precise instructions or try it with the wrong camera, O/S or options). Do a quick google for webcam and raw to see what's possible. They also have written sofwtare that can "stack" images to improve low-light sensitivity and do some neat image processing, too. |

Hi, Owing to ongoing hassle with the next door nutty neighbour OK, thanks all. I'm going shopping for camera and audio modules with things to hide them in like bird nesting boxes etc..., as I don't want to freak out other neighbours down this road who may judge us as paranoid, and attract other theiving idiots who may think we have won the lottery or something. Also as the problem neighbour has a 'tit-for-tat' response for everything, we don't want things to escalate such that doing something worse out of camera becomes his next play. I'll have to be damm careful when installing these so he doesn't notice what I'm up to :-( I've previously bagged a security PVR recorder from long ago on freecycle, and upto now have completely forgotton about it (as ye do when junk accumulates).... It will do for a start. -- Adrian C |

"tony sayer" wrote in message ... In article , dennis@home scribeth thus "tony sayer" wrote in message ... Why IP camera?.. Because they are independent of the recorder. Thats meaningless depends on what your recorder will accept.. Its not meaningless, it is as stated they are independent of the recorder, you do not need a recorder to use them to record images or to view them. They are available in HD without having to spend on a new HD recorder. They are easy to monitor and control from a remote location. So, aren't ordinary cameras?.. Its not a function of the camera its a function of the recorder, so yes if you have the right recorder, no if you don't. You can get them with motion detect So are a lot of other cameras.. I know of no analogue cameras that do motion detection. I know of recorders that do motion detection. and they will email pictures to you so you don't need a recorder at all. That could be a lot of e-mails.. At least they are stored offsite (usually). So no concern for the things that make a quality pix like the lens etc?. You can buy cr@p cctv cameras and cr@p recorders, the same is true of IP cameras. And do they not seem more expensive than ordinary cameras for much the same spec?.?. I think you will find they cost a similar amount for similar capability. -- Tony Sayer |

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Adrian C saying something like: Though looking at the above kit, I'm now wondering about D-I-Y rolling my own with a security DVR card, cameras and a server box. So if anyone has done that with cards similar to Years ago I got a cheapy 4-input cctv pci card, a couple of cameras, and fitted them all to an old pc as recording device. I found the supplied software was next to useless and bought ActiveWebCam - which is cheap and worthwhile and will motion-detect, notify you via LAN or internet and so on and so forth. AWC is very variable, allowing you to set it up just the way you like and it will work with nearly any camera type you throw at it. |
