Honeywell 5811 vs 5815

Both the Honeywell 5811 and the 5815 are wireless door/window transmitters and are both slender in size which make them very popular aesthetically. The main difference between the transmitters is the 5811 is a 1 zone transmitter and the 5815 is a 2 zone transmitter. The 5815 is a little smaller in size than the 5811 and has a longer transmitting range. The 5811 does come in a choice of white or brown whereas the 5815 only comes in white.
