Wireless systems are easy to install because they are literally without any wires and the fact that they can installed by the owner himself is a very big plus point. Everyone will tell you all the good things about these but here is a brief outline on some of the negative aspects of the wireless ones.One of the most common problems that wireless security alarms pose is false alarm. Agreed that it can happen with the wired counterpart but its more common in wireless systems. This is because of the fact that they use radio signals to send the transmission from the sensors that are attached on the doors and windows. There is always a possibility of interference from many other appliances in the house that might pull off a false alarm. This problem is now decreasing with the use of more secure radio signals that cant be interfered and usage of alternative signaling mechanisms.Batteries are another minor issue that might trouble you when using a wireless security alarm. You will need to either replace the worn out batteries or recharge them if using rechargeable ones. Since wired systems are all connected, there are generally no issues about batteries at all. So its more about whether you are really lazy or so busy that you have no time to change the batteries or not.Cost is another minus point with the wireless systems as they are a little more expensive than the older wired ones. This is because wireless security alarms use state of the art technologies and sensors to detect movement or detect an intruder. However, all the good things about the wireless security alarms will make all these flaws look very minor.All the cons about the wireless systems mentioned here is just to keep you informed and not to push you away from using them. They are any day better than the age old wired security systems that are a mess to maintain, needs expert installation and cant be shifted from one house to another if you are living in a rented place.
