CCTV Advice
Some friends of mine own a restaurant in a bit of a rough area.
Consequently, they are having problems with vandalism. They are now thinking of putting CCTV in. The general idea is two outside cameras to cover the main and kitchen door, and one camera in the entryway pointing through a glass door. Does anyone have any suggestions on kit they should be looking at - both for cameras, and a recorder? Thanks in advance. |

Just trying to get them some ideas. although I do suspect that when presented with that question that the answer will be "as cheap as possible - within reason". |

Does anyone have any suggestions on kit they should be looking at - both for cameras, and a recorder? After a potential intruder was trying several back doors in the village in the last few weeks, I just got a Swann 445502, 2 camera system with 1 TB DVR currently on offer from Maplin and Screwfix. 1080p wide angle cameras (80 deg) with IR illumination plus the DVR is web enabled (ethernet) and lets you monitor all the video feeds on your iPad, Android etc. The IR LEDs have a bit narrower beam than the camera FOV but not too bad a compromise. |

However, this is now superseded by IP based systems. Recently, I have built a 6 camera system, based on the Samsung SNO-L6013R. These are Cat5 IP and include Infra-Red (IR) for night vision. A PC can be used for monitoring and motion capture (with iSpy for example), and/or the cameras can store motion capture on a micro SD card and their own software (SmartVision) can be used for play back. Fit some extra IR lights too. (https://www.amazon.co.uk/BW-Illumina...ords=ir+lights) |

Feed it into a DVB T2 modulator and it's available on every telly and monitor. The resolution is easily good enough for a 16 camera matrix display. And of course the DVR is controllable from your PC or smartphone or whatever, and any camera picture is instantly available there. Our customers seem delighted. Bill |

Analogue HD via coax to a DVR is the best system. Bill Please explain? I know lag can be a problem with IP cameras but I have also found reviewing footage can also be a bit slow. Can the disc from a DVR/NVR be swapped and viewed with software like VLC at high speed? To my mind the cameras and infra red illumination are a deterrence. What I would like to add is a few simple things like door/gate open detectors and PIR activated lights with recording of time stamps so the DVR can be viewed for that time, sounding an alarm in the house. Does such a thing exist? Also a few cameras without infra red in strategic well lit areas. AJH |

Cheers, T i m I get the impression Bill has given up with this thread! Or not (as it happens). ;-) I'm just about to buy 4 cameras and a DVR and was going the POW IP route but now wonder about this https://www.jmcsecure.co.uk/proddeta...?prod=T3-821-5 I think the problem 'these days' is one of too_much_choice. In general I think you get's what you pay's for but you may need to look out for cheap stuff that's overpriced. Because I have played with quite a few system ITRW and been party to the installation of some, you really can see how much of a compromise it all can be. Not only trying to get the best value / quality for your money but the right viewing angle and focal length to be of whatever use you were hoping for. A classic example of this would be someone requesting to be able to cover a wide area with one camera but also to be able to capture the details of a face or number plate. You can probably do that but it may be that the one camera would cost more than most people would be wiling to pay for a complete system. Then it's (ITRW), the 'what are you going to do with the information?'. If it's just to prove next-doors cat was killing your fish then that could be easy. To get a good facial image (of someone who may know the camera is there) to hand to the Police may be less so. Again, getting a video of a carerer stealing your granny's money could be easy with a covert camera in a well lit small room. A mate has 5 cameras of different types / costs in his shop and another has 3 on his house and it's interesting to see how well different makes / models (costs) compare, especially at night. It's only when you see a good night vision camera against some less capable ones do you realise what the differences can be. I met a guy who installed CCTV for a living. (as an independent). He had some software on his laptop where you could draw the rough outline of a building and it's grounds and then position cameras and 'see' the view you would then get from each camera and use sliders to give the required detail and visual range etc. At least that way the customer would start to get an understanding that a camera set to display the entire yard, would also be able to resolve a number plate as it came though the gate (so two cameras or one more expensive HQ one may be required). Cheers, T i m |

You can probably do that but it may be that the one camera would cost more than most people would be wiling to pay for a complete system. Yes I have installed a hikvision POE IP system with 7 cameras at my old work, most of the cameras are 4mm focal length but 2 I mounted high on a building are 6mm. The IT guy put them on their own subnet so I could access them directly from the office or via windows X or android at home. They are OK for recording who bumped what in the yard and I can easily identify people I know but detail isn't good enough to identify a stranger. Similarly one can occasionally read a number plate but not most of the time. I did wonder about stacking software to use multiple images and make a number plate legible but couldn't find anything to try. A mate has 5 cameras of different types / costs in his shop and another has 3 on his house and it's interesting to see how well different makes / models (costs) compare, especially at night. It's only when you see a good night vision camera against some less capable ones do you realise what the differences can be. Yes but what I was after was why the analogue cameras should be preferable to the IP ones on a like for like basis. I know ip ones can have a lag of minutes so not much cop for live action but then we are unlikely to monitor live so the recordings are more useful. AJH |

Similarly one can occasionally read a number plate but not most of the time. And that's the thing isn't it, one would assume that any competent system would let you see all such things under most circumstances. Well this is quite clever in that the instantaneous live view is at lower definition for transmission over the internet, the stored video which one can view online is much better but still not brilliant. Trouble is if you increase the quality of recording either with better cameras or more of them at wider angles the retention of the recording drops. I like to have 4 weeks retention, using motion detection. In a large ish yard it's often some time before you become aware something has happened which you need to see. Last month one of our chaps left his van correctly parked in the yard whilst in Portugal and came back to see it had been shunted back 2ft. It was possible to see the change in position and isolate an incident where it had been hit by a reversing vehicle and trace the drier, who is seen examining the damage before moving off. My biggest bug is spiders webs reflecting the IR, it's great after heavy rain and then they start weaving. They are not visible until the infra red lights come on. Like, I *expect* any answering machine to tell me how many messages have been left when I just look at it (as in an illuminated digital display) and from across the room. Like I'm guessing DART / DVLA would assume any vehicle passing under their cameras *would* be read correctly into their systems, assuming it was physically possible (like the number plate was not obscured by another vehicle or using bad font etc) and the same with any camera protected car-park etc. So, it can be done (obviously) but at what cost? Yes there are some ANPR add ons but last I looked it cost £5k. Anyway as far as I am aware vehicles only arrive at a burglary in the closing stages and sure as hell their number plates will be iffy. I did wonder about stacking software to use multiple images and make a number plate legible but couldn't find anything to try. That's a clever idea. Is it already done do you know (is that why you generally see two cameras doing this sort of thing)? Yes the software is used in astronomy and forensics but as I say I have not seen any. Yes but what I was after was why the analogue cameras should be preferable to the IP ones on a like for like basis. I would like to know as well, assuming they are. Personally I think you are likely to get better value if there isn't the cost of the i/p / video capture / storage / server bit, but maybe that is very cheap (comparatively)? But maybe it's not the video quality that is better but the feature set? Or maybe it is better video because it's being digitised nearer the source so less likely to suffer transmission losses? I actually prefer the NVR but as I said I need a faster way of reviewing the recording I know ip ones can have a lag of minutes so not much cop for live action Oh, I didn't know that and that would probably be a deal breaker for me. I would consider any CCTV system as being able to offer me some real-time remote 'eyes', cot 'catch-up eyes. ;-) but then we are unlikely to monitor live so the recordings are more useful. But you would still have the recordings on your DVR / NVR wouldn't you? Yes as I said we aimed to have 4 weeks of recording on the spool before it starts overwriting. AJH |

You don't need a good camera to read number plates. What you need is the correct lens for the distance you are at and a light source that doesn't reflect back and overload the sensor. Easiest way is to have an external illuminator a few feet away from the camera.

Yes a light adjacent to the camera isn't good. However it doesn't need to be far off-axis for the reflections to be much less. If it is far off axis there can be problems with shadows. The main problem with getting reg nos. from moving vehicles is shutter speed and motion blur. This is a major problem at dusk or at night. Anyway as far as I am aware vehicles only arrive at a burglary in the closing stages and sure as hell their number plates will be iffy. Not always.

Is there any differnce in the captured video in any way? BTW I am getting some progress with stacking for number plates, it's only on parked cars at present and you seem to need about 20 frames. This is with a series of images with a 6mm focal length camera at 20m. AJH |

Bill As maybe Bill but IP is a very flexible system especially for CCTV in that its already in the digital domain and is suitable for recording without another conversion let alone being web accessible. In fact we look after a system that has a couple of 5.8 Ghz links in it to do that in an analogue fashion would mean ever more conversions etc let alone running cable in difficult to access places. However distributing digital TV in buildings co-ax distribution is good enough. -- Tony Sayer |
