Comparison Eaglemaster E2 vs Eaglemaster E1

The maximum range at which a regular key fob in a two-way system (see "Type of communication") can receive signals from the central signaling unit. In other words, this is the greatest distance at which the driver can receive notifications from the alarm in the car on the key fob.

When choosing according to this indicator, note that the control range is indicated for perfect conditions — that is, line of sight with a minimum of interference. The actual "range" of the system will inevitably be less, especially in the face of an abundance of obstacles. At the same time, the main signaling units can be equipped with fairly powerful transmitters that can effectively “reach” key fobs over long distances. Thus, the claimed receiving range usually turns out to be on average twice the control range (see above), and even in relatively simple models it can exceed 1 km.

The number of additional channels provided for in the design of the car alarm. Each individual signaling channel is used to connect and control certain equipment. The main channels of the system are considered to be those that initially have a certain “specialization”: for example, one channel controls the siren, the second controls the headlights, the third controls the engine start, the fourth controls the boot opening, etc. However, in addition to them, additional channels can be provided that do not have specialization and are used for very diverse purposes, at the choice of the owner — for example, to control the heating of the passenger compartment or the rear window. The number of such channels in modern car alarms can reach eight; you should pay attention to this parameter if you want to connect equipment to the system that is not provided for by specialized channels.
