Surveillance technology began as a way to deter burglars against theft. They have evolved into systems that can do everything from looking at the inside of your home from 1,000 miles away to ensuring your pets are safe from fire while you are out for the day. Consumer surveillance systems have flourished in the past decade. New advances in technology and capabilities ensure there is a system that can meet most budgets and needs.

There are two major classifications of surveillance technology:

* Hard wired

* Wireless

Your decision to purchase a surveillance system should be based on your needs. It is impressive to have a high-end system that can monitor every room at any time. Is that a system that you need? Opting for equipment or packages that you can't or won't use will be more wasteful in the long run.

Your surveillance system can be programmed to perform a variety of functions. Sensors are available in consumer systems that can detect such things as body heat, break-ins or even air movement indicative of someone being in your home. It is often recommended that consumers purchase the systems that can also perform emergency tasks like alerting occupants over a house fire.

Wireless surveillance systems are ideal for renters. They are also ideal for those in smaller homes or who want to perform the installation themselves. Wireless systems can be portable for easy transport to a new home. Many also offer voice programming and to call specific numbers in case of an emergency. Wireless sensors communicate with the system and make alerts of low batteries, a problem in the system or other such issues.

Wired, or hard-wired, surveillance systems also have their benefits. These systems are wired into your existing walls and structures in order to monitor your home. They are considered by professionals to be more reliable than wireless systems. Such systems are often more aesthetically pleasing and depend on electricity instead of batteries. Consumers also have the benefit of professional installation that are covered under warranties. The majority of companies that contract security systems offer consumer support if you have questions. These systems can also add value to your home.

There are disadvantages with both types of security systems that should be carefully considered before choosing a system. Wireless surveillance equipment may work only when the sensors are placed at the appropriate angles and distances. There will be problems if you place the sensor too far from the system.

Wireless systems are known to go through a number of batteries. You can imagine the energy necessary for a system that is continually monitoring your home. Wireless systems can also be subject to interference from other electronic devices. Several wireless computer networks use a frequency that can interfere with wireless surveillance cameras. Most professionals recommend wireless systems only as a last resort.

Wired systems are not above reproach. There have been complaints about these systems as well as success stories. The price tag on a hard-wired surveillance system can be surprising. These systems are more expensive, and many consumers must also pay for labor and installation costs.

A hard-wired surveillance system also requires access. It may not be possible to run wires through the walls in some areas of your home. This can leave parts of your home vulnerable to intrusion. You may also want to consider the repair costs necessary if you have building materials like plaster or stucco on your walls. These can be easily damaged by drilling and may be difficult to repair. A hard-wired surveillance system is also a perpetual feature. You will not be able to move it elsewhere since it is constructed into the existing walls.

The right security system can make your home safer. It will give you the assurance that you have someone also looking out for your safety. The right information will help you to pick the system that best suits your needs.
