What does the white dome do to the sensor range and angle?

Instead of one solid line it can detect the dome spreads the Rays so it covers more area rather than just a straight line.

You will first need to open up the camera's glass dome; inside the dome you'll find 2 chrome knobs located right underneath the camera lens. You'll need to twist on both knobs to adjust the camera's viewing angle (40-115degrees) and viewing distance (40-120feet)

The PIR sensor is designed for 90° of angle, but we find it effective to about 120° with a shorter range on the edges.

I cannot give you a positive answer but I know I turned around once or twice to re-calibrate it for one thing. I hope you have better luck with it than I did. I junked mine it.

I dont know. :-) the sensor can be spun around 360 degrees but has limited range on its ball joint.

I was worried about that myself, but I had a rectangular box similar to what is sometimes shown below as, "other items you might like ... " in the Amazon ads that accompany the RAB sensor. With the rectangular or octagon surface-mount box, the cover plate usually has four FIPT 1/2" holes - two at a slight angle. This worked great for me because I was surface-mounting the box to a sloped eave. Considering that the surface box and cover plate is a nominal expense, it might give you more options regarding angle of the sensor. If your 4" x 4" is flush mount (inside the eave) maybe all you need is the cover plate with two offset angled holes and two flat holes. Be advised the mount swivels only one direction, and you might have to loosen the mount screw to swivel. If you force it the wrong direction it will break. It has a weird angle when shipped to make it fit inside the carton. This sensor truly does work at 190 or more degrees (beyond 180 degrees) which is pretty cool. Always kill the breaker before installing, no matter how good or comfortable you are working with hot circuits, because you can easily fry the sensitive ICs inside the sensor. I would add that the first RAB sensor I bought was just short of five years old when it began misbehaving occasionally - coming on long before sunset and an occasional false on. I call RAB and they said the warranty was 5 years, so I boxed it up and sent it to the manufacturer. They quickly shipped me a brand new replacement, so now I have a spare to use somewhere else if needed.

The sensors are mounted on the license plate bracket and stick out about an inch from the surface so there is an unobstructed view. To me they are hardly noticeable.

It works well. Just make sure the sensor is facing the direction you want it to.

It has a short mounting stub. I needed a longer mounting stub so I used the one from my old Heath sensor and it fit perfectly. You may not need that modification.

It will detect movement 360 degrees directly below the sensor in an umbrella-type coverage.... Otherwise, It can only detect motion 180 degrees.

White box means that you don't get all the parts that you need to make it work - specifically the special IR sensor.Don't get it. Get the full kit.

You could use an external night vision light and it would be great. Any units that have the light inside the dome could have that issue.

From my experience, any things is moving in front of the sensor about 45 degree and up to 10 feet will work. Make sure you set up the bulb with object moving in front of sensor (the tip for the bulb)

You cannot adjust the length of the detection sensor, however it has a switch for low, medium or high sensitivity. You can also move the sensor if it is aimed at an area where there is constant movement and it gets triggered a lot.

No. It is a fix unit. You can change the angle it aims when you mount the uint, which can change the coverage area of the sensing beams.

It's an IR remote, so you need a line of sight to the sensor on the camera. No need to be directly in front of the camera, but the sensor has to see the remote. I haven't checked the actual range.

No, but its intensity does change depending on the amount of light that it is hitting the sensor.
