The amazing thing about my favorite new toy is that I can rewind and listen to all my old recordings. The Lorex lw2702 wireless recorder even allows me to hear recordings from when I was not at home. All I have to do is check the details on the recorder. It is installed as an intercom system at my house but it can be installed to do many different things because it has very versatile technology onboard. It will tell me if somebody has rung my doorbell when I am away. To go one-step further, I can set a voice tone using my voice on the machine and it can answer when one of my friends rings the doorbell. The lorex lw2702 wireless recorder is connected to the web and it will be able to call me on my mobile if that is necessary. I can choose to accept the call if it is coming from a friend.
