bomberb17 1 Posted June 15, 2014 I've got a Qsee DVR which includes bullet cameras very similar to this below. I'd like to monitor my house's entrance, but the distance between the wall the camera is mounted on and the entrance is about 100ft, so I can't recognize someone's face. So I'm looking for a lens to make the camera permanently zoom into the entrance. (fixed zoom) Anyone know of some that can be attached on this type of camera?

buellwinkle 0 Posted June 15, 2014 Try http://www.m12lenses.com/ as some people have had good luck there. The problem with M12 lenses an IR cameras is you'll have to find one that's the same length. Too long and it won't fit in the case, too short and you'll get IR light bleed from the LEDs. To ID someone with an analog camera at 100', my guess is you'll need about an 80mm lens. We use a 50mm lens at about 70' so I would think you need more than 50mm for sure. Also, you do realize that the IR won't go that far, so you'll have to have lights 100' away.

bomberb17 1 Posted June 15, 2014 Ok thanks for the tips.. So which type of lens should I choose? M12 or CS mount? Do I need a lens holder? How can I find the correct lens that would fit on the cam? Share this post Link to post Share on other sites
tomcctv 187 Posted June 15, 2014 Hi. Your not going to get a lens into that camera for what you want It would be a waste of a camera to try. CNB camera would be a good replacement camera if that is an option Share this post Link to post Share on other sites
milkisbad 0 Posted June 16, 2014 You can get box cameras with 5-100mm lens...if you don't have light at that location, you can try external long range IR illuminators. Just make sure your box camera has ICR to see the IR. But if your entrance is lit it should be fine. Is your camera outside? then you need housing too...

bomberb17 1 Posted June 26, 2014 So most of you suggest that it's not worth to try attaching lens on that camera, correct? The camera is mounted on an outside wall.. So I will have to buy another varifocal camera.. Any suggestions? Share this post Link to post Share on other sites
