How to Choose a Home Intercom System?



Home intercom systems are excellent to provide security to your home. They are also great to use for speaking to people in different parts of the house if you have a large home or multiple floors. However, choosing an intercom system for a home can be quite a process-there are literally hundreds available on the market

A: Create a Checklist of Features you want:

• Determine how much money you want to spend on an intercom system for your home. Setting a budget from the start will help you avoid overspending at the store.
• Choose the wiring system you want. Home intercom systems can be wired or wireless.
• Choose either a video system or a voice-only system. Video intercom systems for your home are great at the front door or if you employ servants. Voice-only systems are less expensive and good for the average needs.
• Decide how many lines you need. Do you want an intercom in every room or do you simply want a connection between two rooms

Shop for the Perfect System:

• Check online for special deals. On the Internet, you can shop 24 hours a day and you can find cheaper prices
• Meet with sales representatives. They can explain to you the different intercom systems that will work in your home
• Ask about installation and warranty. When you choose an intercom system, you want to make sure that it will work in your home and that you'll have the support you need it something doesn't work properly

How to Use a Home Intercom System as Part of a Home Safety System?

You may choose to install an intercom system in your home for the convenience, but you'll probably use it for safety as well. Here's how to incorporate it within a home security system

• Identify the rooms in your home that may pose a safety hazard. Consider bedrooms of the elderly frail, the ill and young children
• Browse the intercom systems available on the market. New home construction offers the opportunity to install a hardwired, less expensive intercom system. The intercom systems are available for completed homes
• Purchase and install the master station and substations
• Teach everyone in the house how to use the intercom system. Consider a code word for emergencies
• If your system is attached to a security door or gate outside your home, create a family password so that strangers aren't let in

How to Buy a Video Security System?



Somewhere between a baby monitor and commercial video surveillance, installing a video security system in your home offers peace of mind beyond what mechanical locks and wireless sensors can provide. Answer the front door without opening it, or watch your children play in their rooms or the backyard--all from the TV screen or anywhere in the world via the Internet

• Plan which areas you want to have monitored. Exterior doors are a logical spot, as well as landscaped areas where intruders can lurk. Inside the house, consider monitors for rooms occupied by children or elderly residents
• Monitor entries with a video door phone system. Most include a weatherproof camera with an infrared lens for night vision. Look for cameras that tilt or pan to show a broader area than a door peephole can. Many systems have two-way microphones
• Consider extra features such as motion sensors, dome (overhead) cameras and a device that automatically takes time- and date-stamped snapshots when a visitor presses the doorbell-- creating a record of who comes while you're not home
• Decide how you'll view images. Basic systems (from about $230) include a 4-inch (10cm) black-and-white monitor and two cameras; upgrade ($350 and up, depending on extensions) to get larger and/or color monitors and more cameras
• Link the system to one or more televisions so you can see who's at the door without leaving your couch. Connect a VCR to record what the camera sees; network with a personal computer to view images from one or more cameras at the same time. An Internet connection lets you view the images from any Web-enabled device. Password systems let you open your front door remotely to let in guests or repairmen
• Create an intercom system with closed-circuit TV access by adding Web cams and monitors. Each system--wired or wireless-- has a few transmission limitations. Some only receive signals within a limited distance. Signals generally travel farther when they're in the line of sight instead of traveling through walls
• Choose auxiliary indoor cameras according to their purpose. In a baby's room, for example, look for an infrared lens and a directional microphone that activates the camera only when the baby coos or cries. Web cams start as low as $20; basic indoor systems range from $70 to $200
