Im not a lawyer, but do live in the UK, and the situation as far as I can see it is as follows:

As its a residential cctv setup, their cameras do not fall under the Data Protection act, so you wont be able to use that against them - if they are being used for the proper purpose,protecting/securing/recording their property etc.

Its perfectly legal for them to use a cctv camera to protect their property, even if it covers some of your property.

There has even been a case where two neighbours put cameras up pointing into a house in the middle of them both, and they used the footage to take a couple to court, and won.

However, they can fall foul of privacy and harrasment issues if they use the system for purposes other than it is designed for. In the example above, they were not harrasing anyone, they were obtaining proof of harrasment of themselves....

In a situation where they are using footage of you on your property, and showing it for a laugh to other people in the street, they are clearly not using the equipment for security, but for entertainment/voyerism, and are not just invading your privacy, but showing the footage to others without your consent.

Where that happens, it may if all else fails, and talking to your neighbour does not work, be worth ringing the information commisioners office as the system may well fall under the data protection act, as it was clearly not being used for protecting their property, but for other purposes such as humiliating you, or entertaining them.

The police could also be involved under the human rights act, for protection against harrasment (the Protection against harrasment Act) etc and may be willing to ask them to move the cameras, especially if you have witnesses that are willing to tell them footage of you was shown to them.

Tread carefully though, as like has already been said before, you have to live next door to them, and having a friendly chat should be your first port of call in my opinion if possible.

Its on ezcctv's website, you need to register as a member first though.

I am using 8.3.1, but cant say if it fixed problems that were in 8.3 as I never noticed any problems specific to 8.3

I would not worry to much about google page rank, these days it seems nothing more than a tool google uses to frighten webmasters into not selling text links, hence less competition for advertisments, hence more money for google whose main business is not search, its selling advertising.

They will all have their own strengths and weaknesses, about the only thing they all have in common is they will be pricey, and their value will depreciate quickly, todays state of the art toy, will be ebay cheap junk in a few years.

Welcome to the forum.

Not familiar with that dvr, but is there a software firewall (windows XP/whatever OS firewall, or a third party one) in use, if there is, have you opened the ports in that also..

You cant really measure image quality properly that way with many DVR's as a still image such as a test card is different from a moving real life image.

Moving real life images present different problems for the compression algorithms used in a dvr. A test card may show great, whereas a moving image may not be that good due to poor compression techniques.

Although I must confess I also tried reversing polarity to check, with the same results (power supply still works )

Have you tested the cameras again with a local power supply after you tried reversing the polarity. Are those cameras reverse polarity protected, if there not they could be damaged now.

Google for SNT DUO Link, there is a full range of products.

I have one that allows two cameras, power for both, and a couple of contact closure signal wires over one single coax...

I have geovision 1480 card and also control center with dongle.

I have had no problem just installing the new version of the software (upgraded a couple of times now, up to 8.3) for control center.

The dongle worked just fine with the new software.

If you contact geovision with your card / control center serial numbers they can give you the download link for 8.3 if you need it.

The 1480 also has a composite video out, ideal for live view, looks great on a crt monitor, or if you prefer cosmetics over what the picture looks like, then you can get tft monitors with composite input.

The rest of your posts have been deleted, please refrain from spamming this forum with junk that is not even remotely related to the forums topics.

Any further spamming and your risking a ban.

What country would this be for? If it is in the UK, you may need to take into consideration the ICO (information commissioners office) recent decision regarding cctv in schools. If your in the UK shout up and I can post a little more info (not that it makes much sense, its a crazy decision I think...)

I would just look on ebay for a cheap second hand multiplexer that has picture in picture. I paid about 20 uk pounds for a robot mvp16 multiplexer that has picture in picture capability. There are probably loads of second hand devices going cheap with pip....

Touch wood I have never had to send anything back under warranty apart from a liteon dvr recorder that went back in the first few days.

Everything else that has had a warranty has lasted fine, so far..

Apart from a IBM laptop that the screen started to fail - the day after the warranty ran out!!!

I prefer a longer warrenty.

I would buy a seagate drive with a five year warranty over a rival exact same specification drive that has a 3 year warranty.

Same with cards, cameras, etc - a long warranty not only lets you have peace of mind, it to me proves the manu has some faith in what they are selling.

They are unlikely to provide a multi year warranty on a peice of junk, and if it does turn out to be unreliable junk, at least you have years to send it back!

Most equipment should last years these days, so there is no reason manufacturers should not stand behind their equipment.

Isn't it funny that the people that theoretically SHOULD have the money and the wherewithal to know that they need to spend money on something like this, are the biggest tightwads?

Thats often how they become rich in the first place, being mean and tight fisted... Cant say I have ever met any generous rich people in my life.

Come to think of it, never met any rich people that struck me as particularily intelligent either. They must exist, just never come across any that I know of yet.

The white one is the older version I believe, unless a new version has recently been introduced. (http://en.wikipedia.org/wiki/BT_Home_Hub

On the new version (v2, curved black hub with phone) you need to go to

bthomehub

in your browser and then set up port forwarding in 'application sharing'

You need to set up a new application, such as 'cctv device whatever' and list the ports that need forwarding, you can then assign that new device to a device on the network.

Not sure if its the same on the older versions, but there should be online help if you go to bthomehub in your browser.

You may need to go into 'advanced settings' to see many of the available options.

http://portforward.com/ has lots of help on port forwarding for many applications and routers, its well worth a look to see if what you are after is covered.

Im not sure how they expect to make out faces if the camera view is covering a large area, and the cameras are standard analogue cameras.

Take for example the outdoor shot, that is covering a huge area, you only have a maximum of 768(H) x 494(V) (ntsc) or 752(H) x 582(V) (pal) pixels on the camera ccd to play with.

Lets say at a guess the area is 60 foot wide, that would be 720 inches, which would mean

720 inches / 494 pixels = approx 1.45 pixels per foot.

That would roughly mean 1 pixel would have to cover the entire width of a human face.. Not likely to get much facial recognition there....

Similar for height/depth etc..

Thats in a perfect world, there are many factors that will make things even worse than that, such as compression on the DVR, recording at 640x480 (if that is being done), signal loss in cables etc. But even if everything was perfect, there is no way you can get facial recognition on a wide area shot like those.

The shot is just far to big to get anything more than an overview.

You either need to go mega pixel, or get PTZ (with alarm inputs triggered by sensors outside to move the camera to where the intruder is) or more cameras each covering a much smaller area.

If they are experiencing a problem at night, then there is probably insufficient lighting for the camera.

They use those a lot in the uk, there are quite a few mounted on very tall poles near where I live (they have more poles than cameras, as they are setup on a wireless system so they can install the cams where they think they are needed).

Should be fine.

According to wikepedia cat3 is a twisted pair cable, so it may be worth checking to see if the cable is twisted or not...

http://en.wikipedia.org/wiki/Category_3_cable

Although I have not used cat3 cable for cctv, NVT's learning center states that their baluns can be used with cat2 or better cable, it also states that some people have had success with non twisted cable (but they dont recommend it)

Can Category 6 cable be used?

Yes. Unshielded Twisted Pair cable, Category 2, telephone or better, can be used with NVT.

Can un-twisted cable be used?

Some customers have successfully used untwisted cable. NVT does not recommend it due to its interference susceptibility.

link - http://www.nvtuk.com/learning.asp

They also state that there is no problem with multiple video signals in multi pair cables

Can I transmit more than one video signal in a multi-pair cable?

Yes. One of the benefits of using NVT transceivers is interference rejection. NVT video signals can reside in the same cable bundle as multiple video signals, Ethernet, 24VAC, RS-422, RS-485, etc.

I cant see why it would make any positive difference at all, that would be viewable to the human eye.

If anything, using a connector made from a different metal than the mating socket may actually introduce the risk of disimilar metal corrosion (speculating here, as its not a area I am expert in...)

http://www.roymech.co.uk/Useful_Tables/Corrosion/Cor_bi_met.html

http://www.1st-coating.com/protection_contacts.htm

According to the above charts, zinc seems to react with a lot of metals, if a reaction did occur it could cause a negative effect over time on the picture, and the life of the connectors...

No idea if it would happen though, but I have seen warnings in motherboard manuals from time to time warning against adding gold plated sims to tin plated sockets and vice versa due to this problem.

Any chance you could post some (or pm) some sample images?

No, it wont work plugged in to your mouse port.

The connector looks a bit like a svh-s one, but it has more connections on it, so cant be that.

It looks like that one connector is supplying every connection to and from the camera, there are no other connectors on the camera?

If its the only one, then it must be designed to work with the special monitor that would have been supplied with it, the connector would have to supply sound (both ways if used at all), video to the monitor, and power supply.

Unless your able to figure out from the board what pins do what on the connector, what voltages etc you need to supply etc then I would just sell that one on ebay and pick up a 'normal' camera cheap second hand on ebay to play with.

If you need something for real security though, you may be better buying something decent though...
