Question: What is the viewing angle of this "Wide Angle Lens"?
Document: I was uncertain which to chose so I tried both this one and VideoSecu Day Night Vision Outdoor 28 Infrared LEDs Weatherproof Security Camera Built-in 1/3" Sony CCD 3.6mm Wide Angle View Lens (Power Supply Included) WE7.Primary reason I kept the eSecure is better color. I could not get the VideoSecu to be true to color.Both have nice thick aluminum.
I have two of these and am pleased with them. Not as wide as my 2.x lens but good enough for the application.
wide angle, clear view , you can see someone face about 25 feet out .Night vision  great I do not have outdoor lighting and still this camera picks up good
With the wide angle lenses I can put one on the front of my home to cover the front and one on the back of my house to cover the back. With one of the bullet cams facing these dome cams and one bullet on each side of the house. Should give excellent coverage. I like being able to lock the cam in place with the allen wrench. That should keep it pointed where it needs to be pointed. Really Great camera for my needs.
After trying a few other disappointing night vision cameras, I ordered this camera and I am very happy with its performance.I have this camera mounted under the eaves of a two-story home looking down on the driveway. The wide angle lets me see the entire driveway, garages, and street, and the resolution is good enough to see small objects (like the newspaper) at the end of the driveway. It can't read license plates, but I wouldn't expect this camera to be able to do that.
I just setup this camera tonight and boy am I impressed. I had ordered a 960H system with 4 600TVL bullet cameras (6mm). I needed 2 more cameras so I thought I would try this one to see how it worked. Well, it works Great. It is a wide angle camera (3.6mm) with very good quality picture. Better than the other 4 cameras that came in the system I ordered. The night vision is also very good. I have No Complaint At All.
I purchased this to upgrade one of my cameras in a Lorex system I purchased recently. The 700 TVL is a much better picture than the 480 TVL Lorex cams. Picture is brighter and color is much better as well. The 3.6 mm lens does cover a larger area than the cameras that I had. The IR Lights do have a low red glow when they are on at night if you look directly at it.
I ordered two of these cameras and was surprised by the low price $37.99 including shipping. I got them to the job and installed them and went to focus them but there is NO FOCUS. I have two double vision cameras that can not be focused. I have never seen a security camera that could not be focused. A fixed lens sure like 3.6mm vs a variable lens which would be like 3.6mm-12mm but always a focus.
I have been using my Zoneminder based security camera system for many years, but have never been able to find a low-cost IP based camera that has the right combination of view angle, night vision, and resolution. For the most part, these cameras all seem to have software flaws that result in glitches and dropouts.
I created a small wedge shape block to correct the angle of the base and allow the camera to be positioned higher up. This isn't an issue with the camera itself, but with how I am trying to use this camera in a non-intended application.Overall I am very happy with this camera, and will likely be purchasing more to replace the other IP cameras in my system.
Answer: About 180 and the cameras have good clarity. I would buy more for the price...good camera.
