home outdoor camera

[ringtone 0]

I am looking for an outdoor camera for a back door. My requirements are as follows:

 

1. see a person about 25 feet

 

2. work outdoors

 

3. work in low light

 

My idea was for an outdoor dome camera with a 10mm lens. Does this makes sense?

 

I see that resolutions range from 400 lines to about 700. Does this matter?

 

Any suggestions would be greatly appreciated.

10mm will give a fairly tight shot with a 1/4" sensor... how wide an area does it need to cover at that range?

 

More importantly, what's your budget? Take a look at CNB's Mona Lisa line of cameras - they're a vandal-resistant 600TVL dome with outstanding low-light capabilities. You'll generally find them in the $250-$300 range.

+1.

 

Here is a simple cctv lens calculator at http://www.webcam123.com/en/faq/lens_calc.html

 

Also, at this price point, longer lenses typically mean less light, which means giving up some of the low light performance, so a wider lens will help in that regard as well.

My guess is that I would want to see 6 feet by 6 feet at a distance of about 25 feet. I will check out the calculator.

 

One of the models I am considering is DVC-CMD728HW. The specs may be a bit to good for my purposes.

 

"680TVL 36IR Color Dome Camera, 1/3 inch Sony Super HAD CCD, Hitachi 14 Bit DSP, Starlight 0.001 Low Lux, 2.8~10mm Vari-focal Lens, SDNR, SBLC, 256 zone exposure, 256 zone ATW, Vandal Resistant, Weather Proof, Indoor/Outdoor, White"

 

I don't know anything about LTS brand.
