Default Correct Surveillance Camera

I need to know what specifications to look for on a porch camera. I want to be able to have good facial recognition in a 20 - 30 foot range. The cheap camera that came with the DVR doesn't quite get there (420 TVL) and the high-resolution one (600 TVL) I bought seems geared more for the 100' range. It doesn't have sharp focus in the range I need. Camera should be bullet style for under-eave mounting, outdoor, color, low lux with IR LEDs. Specifically, what specifications should I be looking for?

Thanks

I used the Foscam 8906W wireless IP outdoor camera. I tried one for a month and it seemed to work great. I just order 3 of them through groupon to put together a home security monitoring system that will record a couple of days worth of video so it can be saved and looked at if necessary.

I have an Axis p5534. Its a HD camera 1280x960, POE+, full PTZ, and integrated management system. Granted it retails for 2k+, but i can pick up a license plate with cars a block away. It encodes usin h.264 and outputs .mkv files.

Thanks guys. I guess I should have mentioned my system is not network (IP) type.

Look for a line of res of 600 but 400 is more common. For low light check the LUX rating. Anything greater than .01 LUX is poor. Sony makes a HAD technology camera with a LUX of .001. Will see with moon light. A little IR make like daylight.
More or less second is features like Variable Iris control and pan tilt.
Tamron makes some good lenses check the ones listed as IR compatible.

Thanks guys. I'm going with this one. The 2.8-12mm Varifocal lens should allow me to get a sharp focus in the 20 - 30' range I'll need for the facial recognition. The Super HAD is a plus.

If resolution is what you are after… you really have to step it up to IP cameras.

Camera & lens quality is pretty important.

I don’t know how much you are willing to spend, but stick to brand name cameras like Axis.

Personally I really like the Mobotix cameras, but chances are its going to cost more than you want to spend, but nice software is included with the cameras.

Take a look at some of the features and video sample… might impress you.

LOL, yep more than I can afford. Maybe when I need to replace what I've already got in-place. Right now I just want to get a good face shot.

Have you tried to back focus the camera and lense.

With no external adjustments and woefully lacking manual (actually a single photocopied sheet ), I didn't even try.

A camera lense combo that should produce 600 lines should show warts and all at porch distance. If the set up has separate lense and camera body with something like a C or CS mount then it can be back focused to correct the issue and produce very nice pictures. Here is a little info.

Have fun its a hobby.

I wouldn't go so far as to call it a hobby. Not for me anyway. Thanks for the link.

Been down this lane before...

A simple hood or hat will render an expensive system useless.

That is what you have all cameras overlap so that if someone f's with one camera, they are caught on at least one other camera.

This is a home security situation. If someone is lurking around the property intentionally hiding their face, that's a clue to take defensive measures, no?

Did you already order this camera?

I have a couple of these cameras.. grey in color

They are ok.. good IR 20-30 feet should be good to go.. Let me know if you want one..

Also you can look into HD sdi .. assuming you have camera's ran in coax.. its an upgrade to IP quality. Also there is 960H which is an improvement to D1

Thanks
