Wuzi
Iâm going on holiday in a few days and I thought it would be a good idea to get one of those cameras, since thereâs been a lot of housebreaking recently.
Hereâs what I need:
- It should be able to be outdoor, eventually under the rain
- It should have a good night vision, to recognize number plates
- It should be all digital, and be able to record onto a hard drive as long as 2 weeks or more
- It would be cool if I would be able to check whatâs going on via WLAN for example. I saw some cameras that have WLAN, and you can see whatâs happening via your iPhone or your browser. The thing is, those I found needed Internet Explorer or stuff like that⦠I need something Apple compatible.
Also, I was thinking of getting more than just one. How can I record them all onto a hard drive? Do I need to create different folders for each camera on the hard drive, and then select this folder as the recording destination for each of them?
Iâm pretty new to this and itâs all a bit complicated for me⦠also I find thereâs way too much choice.
And the price of course: The cheaper the better, but I donât want something that wonât work anymore after a week of course!
Thanks very much!

You need cameras to be "weatherproof" so that they can be placed outside.
You want to get cameras with "Infrared" so that it has night vision and you may want to get them with "600-700TV lines" so that it recognizes faces and license plates.
You need a DVR with a hard drive installed. You wont know what hard drive size you need until you decide how many cameras you want on the system and if you want it to be recording 24 hours or set it on motion detection. That will determine how much space you need to record for at least 2 weeks before it overwrites itself.
Most systems now a days can be view remotely via pc, mac, and smart phone.

Security Cameras at night?
Nubian Kin
Are most security camera, that we see at the mall or on court houses, etc... equipped with night vision, or do they usually get poor picture quality at night, without ample lighting. I am making inquiries from law enforcement because I am trying to catch a car burglar at a friends bar. We have looked at a few fixed angled cameras like the one you see on the side of buildings. How good is the picture quality in a dark parking lot. They have no infrared or night vision that I know of. Will a camera like this produce a good night time image, and from what distance? How effective are night vision from distances? Im talking 20ft or more, without someone monitoring the camera to zoom. I figure that law enforcement officers have view more surveillance footage then the average citizen so I would like to hear from you all on your experience on nighttime CCTV footage. Thank you all in advanced

Yes, is the answer to your first question, they have to be in order to be able to pick up the image on the camera. However even with a good infrared camera having good lighting is a must.
If an infrared camera is placed in a parking lot where there isn't any lighting it will be difficult to see the picture. It there is low lighting the picture will be some what grainy and you may see some of what is out there. You will see the pixels on the monitor and the picture will be some what grainy, as well as there being shadows. The distance that you may be able to see in low lighting when using a camera may be cut in half. But you will still be able to see some of what is going on.
In order for the picture to be clear there needs to be good lighting in the area where the camera is to be placed, that will give the best picture quality of all.
With a good inferred camera/zoom feature and even being able to pan the entire area that is being monitored at 20 feet you would still be able to get a clear picture with proper lighting.
I hope that this helps answer your question. God bless.
