Narrative:

I was on an IFR flight plan to caldwell; nj (cdw). The airport was in sight and I had received clearance for the visual approach to runway 4. I was handed off to caldwell tower and was instructed to fly straight in to runway 4 and report 4 mile final. I was descending to pattern altitude at a relatively slow rate of descent (around 300 FPM) and inside 10 miles from the field. Pattern altitude is 1;200 ft MSL. At around 2;000 ft MSL I received a low altitude alert from the tower controller. I was constantly in visual contact with the terrain which did not appear to be unsafe. I am aware that the terrain southwest of the field is somewhat higher than field elevation but I was in visual contact with the approach end of the runway and with the ground below me. I then arrested my descent and continued my approach. Distracted by the tower's communication and by my wife asking what that was all about; I remained high and then had to make a greater than average final descent to land. The mooney is somewhat hard to slow down especially in a descent so I try to get to pattern altitude by 3 to 4 miles from the field. In the future I will probably load the GPS approach so as to get safe glide slope information even on a visual approach.
