Hi OzB,
Need some advice on a wireless camera I can install outside to that has enough quality (1080p?) in the recording to identify people.
It will be installed in a driveway with about 15-20m distance from where it will be installed.
There is a bit of light from the street lights but not a whole lot.
Looking at a budget of around $100.
I'm assuming because you're asking about cameras, this is your first time at installing one ?
If so, here's a few things to keep in mind..
Privacy
Make sure the camera does not overlook anyone elses property, and in some cases, even the footpath can be a contentious area.
Lighting
Most cameras are completely crap at night time. Those LEDs that are ringed around the lens are good if the person sticks their face up to the camera, anything further than that, they are useless.
Better option is to buy an infrared bulb, or even one of those UV bulbs and stick into the outside light socket. The camera will pick up that light easily, giving you much greater visibility.
Conversely, during the daytime, you want to make sure the camera is not facing a surface with high glare - such as the footpath as this can bloom out the camera and potentially damage it.
Recording
Not sure if you're wanting this for surveillance or just to see when Mum is popping round, but if it's the former, you'll want to consider some way of hooking it up to either a DVR or PC. If it's the latter, then plugging it into the TV will be fine. Make sure you check what connectors the camera has, as a lot of them still have the old BNC connectors.
Alternatively, having an IP camera will allow you to see the camera from a PC or phone/tablet.
Temporary vs Permanent
You'll have to consider powering the camera, which are typically installed under the eaves of the house. If it's a temporary thing, say for the weekend, then a battery pack may suffice with a cheap wireless camera.
If it's a more permanent fixture, then you'll need to consider running power to it.
Brand
Swann are the most prolific, but you can pick up some cheap DLINK outside cameras on eBay. I've used both, and would recommend Swann over DLINK, as it copes better with the bright sunlight. The DLINK just blooms out overlooking a garden, whereas the Swann is just fine in bright sunlight viewing the driveway.
Your software option will differ too, with the options of having a set area to monitor, emailing and uploading video offsite, remote access, etc
There's plenty of cameras to choose from, but it really depends on your requirements as to which brand to go with.
Hope this helps
