What does 0 LUX with IR mean?

Means that with the Infa Red it can see in total darkness.

Quote

What sort of MINIMUM LUX should I be looking for in a camera?

For night time, the lower minimum lux determines the camera's suitabillity for darker situations.
Be wary of some of the quoted lux claims for non-illuminated cameras.

The LED's on the camera will provide some IR illumination but not really effective ver the distances you require, hence the requirement for an additional IR flood with a better spread.

Cool, thanks for the advice... I think I am going to use dome cameras as you suggest. Just one question. I understand I need extra lighting, but what are those LED's surrounding the lense in that camera you have posted? Do they not offer light at night?

Yes they do but you will have to satisfy yourself that the range specified by the manufacturer will meet your needs - professional I/R will always be best but as I posted previously its expensive, the type of camera I highlighted is an economical alternative for many domestic uses.

Just be careful though not to over do the lighting..

Wow!, but before I go on, I don't think I understand the use of the IR LEDS. When they are lit up, are the visible to passerbys?

Do they all light up the second it gets dark or only when there is motion? If the answer is "when it gets dark "do they provide enough light for the lense, and therefore I still need extra light from another source.

Not to throw a spanner in the works, but I came across this web site called AXIS Communication and they deal with IP Camera's and I found a dome network camera that works during the day and at night.

I just fancied the idea of a network camera plugged into my LAN and having the ability to remote view from work over the internet. Of course this would mean no DVR but rather a dedicated PC set up.

Of course the Axis Site didn't mention the cost of this camera (AXIS 225FD Fixed Dome Network Camera) (if anyone has a rough idea or a web link of a site selling them, that would be much appreciated).

Any comments on this type of camera...

cheers

P.S. I found a great PDF file answering almost all of my questions (I guess I don't need this forum anymore... :banned:

) No, I got plenty more questions and again a BIG THANK YOU to everyone who have replied to my posts above. I have learnt a great in the past two days.

I'd steer clear of the IP cameras for now. for what you can buy a semi-decent IP camera for you can get a decent conventional camera and DVR with LAN.

Obviously if you are going to use 2 cameras then this price gap will increase making it seem even more un-feasible economically.

500ish, Samsung 520, housing, IR flood and entry level 4 channel DVR (LAN, 80GB HDD, no CD-R). Might go a bit over the 500, but not too much.

Entry level DVR
An essential item for CCTV systems.This 160gig hard disk, 4 camera digital recorder with CD writer to put evidence on to give to the police. It is ideal to replace old video machine recorders.Can be swapped over in ten minutes. Network connection supported.There are no tapes to change daily and gives higher quality digital images. This unit can record 4 cameras at once and can record for several weeks depending on the number of frames per second you require. Can be programmed to re- record over disk from the beginning again automatically when full, simply switch on and forget!

Flippin eBay, but not a bad little unit.

and a couple of these should do.

Silent Witness (Honeywell Video) dome cameras are Sledgehammer proof, allthough ive never tried this is what they claim so they will handle bottles rocks etc. You can get DAY / Night cameras in this range also as i have one, although they are quite expensive. Also it will nee IR lighting or floodlighting, you may be able to get away with a floodlight for the front of your property on a PIR and and IR lamp (probably a spot, or medium beam) for over the road.

pete would you not recomend using a dvr with cd-w LJD do a 4 channel dedicated lite model with cd-w and and lan features and not use a combi tv. This could then be patched into the main living room tv for veiwing or a tv in the master bedroom.

I could sell you a Vantage Sony chiped true day/night dome.

When you say Vantage Sony true day/night dome, can you give me an example of one or spec sheet of the device? (what it offers, range etc) Why is it chipped? As opposed to something that is not chipped? What does that mean?

(mounted at street level you will get a good view of this side of the road and dependant on obstructions not to bad the other side (picture small and wont be lit))

What does mounted at street level mean? How high up on the wall?
What does picture small and won't be lit mean?

I'll certainly have a think about your offer.

All cameras are chipped, basically referring to the chip doing the work in the camera (a la PC CPU type of thing). So a Vantage with Sony chip is a Vantage branded camera with Sony chip.

I had a look at that DVR, and it's ideal.. I really like it.

And you think those dome cameras are fine for my purpose. I was surprised at their price.

That DVR is fairly descent, and manufactured by LJD as mentioned above in Pete's post.

As for the camera, well i'm in the process of deciding wether to get one myself, or try out these cheaper Sharp based one's.

eBay listing for the Sharp (or is it sony) Day/Night Cam

Right, I am still staying clear of IP Cameras but found this on gadspot.co.uk and for 328GBP was thinking Is there something wrong with it? Almost half the price of that dome IP camera I was originally looking at, and it's Pan & Tilt. Of course it does not have to be pan and tilt, but I was just wondering.
