the board auto-imported all of your links and then hosted the full-size images from the board account...Just noticed that, they should turn that off.
Might have issues with copyrighted images.

have you tried there cameras ..... beats computar
Tamron Cameras?
-
Tamron lensknow that is the King of analog cameras
Not sure if I would use them again.
They were okay, but I may go Computar instead.
Used both and fujinon over the years though.

And this gives an example of how a BIG area compares to a SMALL area
And how the performance of something like a cheap color IR can vary considerably from one location to the next ... ofcourse your miles may vary!

What point was Rory's pic making 'exactly'? It's a great shot- 700 tvl with no noise! LOL!its a true D/N with no IR. an image you will never get with a gadspot.
It has IR, but very little due to being short range and 940nm.
But even with hardly any IR one can see how amazing it handles itself in low light, as the IR beam itself doesnt even go as far as the jeep in the image, in fact to begin with I thought the IR was not even working. Im only using it on a job as a TDN though, as it doesnt need IR in that case. I would like to try their step up with the longer range IR sometime, but it costs $50 more, and can only hope the actual camera is the same but only with the additional 830nm IR instead. But the thing that really impressed me was the color night image, all other TDNs I have tested dont match it, and ofcourse color IR cameras dont even come close to it.
Even though its a Sony Effio, I used the $60 Sony Effio indoor dome from KT&C also, had to send 17 of them back!! it was a horrible image full of noise. Ofcourse the camera in the image above costs from $230, big difference from $60, and shows that cost really does matter .. sometimes at least

He's Canadian, do they even have social security numbers??
Anyway, in my country everything is still on paper .. i wish our government could find those things, let alone anyone else

Altronix.
There are various models but it will depend on your camera amount and total current draw.
-
my point exactly rory thank you.Best TDN camera at night I have used in a couple years, blows away the monalisas.
Best image yet with that dusk to dawn light, all others still produce noise or the light glare kills them - this was perfect.
That is pitch dark on right by the way, it is short range 940nm IR LEDs.
They have the step up with much more IR.
-
any camera that states 750tvl is usless when used with white light i.e flood your lucky if you get 580/600tvl
and then you have the other problem. as seen by 3 new posts just last week 700tvl at night the ops are seeing what they call snow big white dots from the camera to the point you cant see anything and plays hell with alarms set.
best with low tvl with IR 520-560 is say the limit
700TVL 960H Sony Effio from KT&C

You would need to do this using server side scripting if the camera server does not support it.
Eg. log each visit based on session.
When each session times out minus total connected users etc.
You need a developer that can work with the web server you use.
Or learn the code yourself
-
I would always use 24VAC if the camera supports it, unless ofcourse you are doing a basic 4 cam install sharing 1x 12VDC PSU and are all short distances.

Is the house for sale?
-
Ok, the house has a few cameras around it, and some yard beams.
Nothing special with that.
-
Okay, I'm not coming in this thread anymore until those pictures are made a reasonable size... every time one loads, the screen jumps, and I lose what I was reading.That's really odd, they loaded fine for me.. Must be your internet connection loading them slowly.
Atom netbook, it does the same on mine.
Cant handle all those huge images at once.
-
those other things are photobeams
-
No power to the cameras so doubt they are even working.
Probably just dummy cameras at this point.

as for the DVR, i was lucky to get a new demo unit for free to test, but i never bought a hard drive for it yet. if you cant get a demo, least by a new DVR.
Dahua budget unit with same network software and most of the features of their more expensive units, costs approx $140 retail for a 4 channel (eg. QVis Zeus). Be warned wont be able to upgrade the firmware and it may be a little lower quality in some cases, but hardly noticeable - either way it blows away the cheap DVRs of times gone by. Hard drives are expensive these days, so what I did was at first just recorded it over the network to my PC .... later someone was upgrading their hard drive so I got their old hard drive for free.
The only thing I ever paid money for was some cable, everything else was free

the poor mans road ...
just get cheapest best cams you can afford and focus them in on choke points.
eg the path which someone would enter your property, or front door, etc.
throw up a couple cams for general overview also.
you can always switch individual cams out later.
low res is fine for small field of views like choke points.
get higher res for larger areas.
1/4" high lux cameras will help with low noise, but wont see anything in low light.
if you need extra IR buy a 6mm $20 IR bullet camera off amazon and use just the IR from it.
if you already have a cheap color IR with alot of IR but crappy camera, and want to upgrade the camera, get a decent day night without IR to save money (eg. CNB VBM-24VF) and then use only the IR from your old cheap color IR for extra light (if needed).
also consider 2nd hand cameras, eg. where the IR burned up on a TDN IR Bullet, just use the camera without IR or add IR separately as above. Older and some newer IR bullets let you easily disconnect the IR ring and it still works as day night.
All my cameras at my appt are 2nd hand which were either broken or just old.
Had to move them around and adjust until i got the perfect shots (best possible with what I had).
Ofcourse they continue to change as I get my hands on better 2nd hand cameras

Every other company with a website also claims they are a manufacturer...Just like every other person with a pickup truck claims they are a contractor...
Yes I "manufacturer" everything on my website
(i put the html and code together )
-
True? Not true? Beats me really. I don't mean to push any one place. I just have some of their cameras so I can at least say a little something about them, that's all. Product choice is a personal decision in the end and like I always say about anything- YMMV [your mileage may vary].
Every American company says that. Fact is nothing much is made in the US anymore, even i-phones are made in China. Cheaper labor.

You guys realize gad spot is just a whole bunch of different cameras from different manufacturers right?

if you buy 1 optex you get the beams and cover if you need hight in your beams you order just the beams and no cover. and buy a fixing cover to the hight of the beams which work out at the same price
The optex photobeams consist of a receiver and transmitter - single or dual IR beam.
And they vary in distance (and size) based on the model you buy.
How does that relate to the redwall, which is a totally different product?
