Home Security

When you are concerned about the safety of your family’s home or your business, the first thing you want to look into is a sufficient number of security cameras to deter break-ins. We will discuss two main advantages and one single disadvantage of surveillance cameras, wireless type, for your home or business. The two advantages are: No cable installation and no need to protect cables. The two disadvantages are the wireless signal subject to privacy concerns, and the possible weakness of the signal. Let’s look closer.

Wireless surveillance cameras advantages

Depending on the size of the house or the business, the wired cabling can be quite a chore to install. You would likely need to install the wires high up on the walls which poses a risk of fall. And whenever you decide to change the location of the control unit, the DVR, or the cameras, you would have to recable again. There are no such worries with wireless surveillance cameras.

The second advantage of wireless security cameras is related. When placed inappropriately, visibly or, unprotected, the cable can be the easiest for a potential intruder to cut, thereby preventing the operation of the camera. With a wireless camera, the intruder would have to physically access the camera to disable it.

Wireless surveillance cameras disadvantages

There is one main potential disadvantage of a wireless surveillance camera setup. That is a security concern. The wireless camera signal is available up to several dozens of yards away from the camera, and is available for anyone with a receiver to collect. In principle, given enough time and computing power, such wireless signal can be deciphered and decoded, and after that your wireless signal will be openly available to the intruder. You can manage the risk of a security breach by regularly changing password on your system, and by employing the highest grade encryption in your wireless communication.

The second disadvantage mainly for larger houses and businesses is a limited range of the wireless signal. Particularly when the signal has to traverse walls to reach the receiver, the range of the wireless signal may not be sufficient and your camera image will suffer. This is less and less of an issue with the introduction of new powerful and long range wireless-G and wireless-N signal standards.

There are many reasons to choose wired security cameras and many reasons to choose wireless security cameras. The things you should consider when it comes to choosing to go wired or wireless should include the size of your home or property, the placement of the cameras, and the cost. Wireless systems are becoming more affordable all the time, but they also tend to be a little more expensive than a wired system.

Another thing to consider is the distance of the wireless signal being transmitted. Some wireless security cameras have a one hundred foot signal limit, while other systems can go up to one thousand feet. A wireless system with a long signal is very convenient because you can place them in many different, hard-to-reach spots, without worrying about wires or cords. This means you can have your cameras in areas that don’t have the proper outlets for the alternative wired systems.

But wireless security cameras are not the only option, or always the best option. A wired system also has many benefits. For one thing, wired cameras tend to be more cost effective. For another, you never have to worry about dropping the signal or suffering from interference and other complications. You also do not have to worry about something obstructing or otherwise negatively affecting the signal. Wired systems can be placed almost anywhere a wireless system can be placed, and there are ways to hide the cords and wires that are attached to the wired system.

In summary, take a broad view of your goals with your surveillance system before you choose to go wireless or hardwire your system. Be sure you understand how the cameras will be installed and if they will work in the areas you need them. Finally, be sure to do a quick cost comparison to ensure you are not spending money needlessly, simply for convenience.

Depending on the size and style of the home, alarm systems can be easily installed using the old type of wired security devices. However, some homes use a wireless home security alarm system to make installation quick and easy. Installation of a wired system requires drilling and pulling wires through walls or into basement and attic areas, which can be time consuming and dirty work. Typically, this type of system is left to the professional while a wireless home security alarm system can be done by the homeowner with little effort. Additionally, the components of a wireless home security alarm system can be easily moved around the home to provide protection where it is needed. Adding on to this type of system is also easy, however every receiver has limitations on the number of devices it can handle and staying under the maximum acceptable number of devices will insure the system functions properly.

Every device connected to a wireless home security alarm system has a built in transmitter, which sends a wireless signal to the receiver. Most of the less expensive systems will simply sound the alarm when a device is activated. The more costly ones will not only sound the alarm, but also indicate which device caused it to activate. This is especially helpful when troubleshooting a false alarm or in figuring out in which room there is potential danger.

While the ease of installation ranks high on the list for a wireless home security alarm system, there are some disadvantages. The transmitters used in wireless devices operate on batteries, which will need changed frequently. Using motion sensor cameras can save the power when the cameras are not operating, but the batteries will drain periodically and will need to be changed. Additionally, as the battery weakens, the distance it can send the signal becomes shorter, creating the potential for a false alarm.

The construction of the house can also limit the distance a signal travels. While many wireless home security alarm system devices can send out a signal between 200 and 300 feet, depending on its quality, brick and metal walls slow the signals considerably. It is possible that the signal strength will be cut in half, or more, if it is trying to penetrate especially thick walls. The unit may still function properly, but if the signal cannot reach the receiver, the alarm is not going to work.

Wireless home security alarm systems are all the rage with ‘Do it Yourself’ home handy persons. The DIY handy person is much more able to cope with the installation of a wireless home security alarm system because it so much simpler to install than the traditional type of wired security devices. The set backs to a conventional wired system from the home handy persons perspective is the large amount of drilling required, which is time consuming and dirty work. Typically, the wired security system is left to the professional, while a wireless home security alarm system can be easily installed by the homeowner.

As an added benefit with a wireless home security alarm system most of the components can be easily moved to different positions around the home to provide protection where it is needed. This flexibility, however, is offset by the need to ensure that the number of installed devices are within the maximum recommended range so as to allow the wireless home security alarm system to function as designed.

Typically every device connected to a wireless home security alarm system has a built in transmitter. This transmitter is designed to send a wireless signal to the system’s centralised control receiver. It is common that the inexpensive systems are designed to simply sound the alarm when a device is activated by an intruder. However, in the case of the more costly wireless home security alarm systems, they are configured to not only sound the audio alarm but also to indicate which actual device set off the alarm. This extra benefit is especially useful when trying to identify the cause of a false alarm or in figuring out which actual room holds the potential danger.

Wireless Systems Have Distinct Disadvantages

While the simplicity of installation ranks high on the list of positives for a wireless home security alarm systems, there are some quite obvious disadvantages with this style of security system. One such negative is the fact that the transmitters in wireless home systems operate on batteries and this means they have to be regularly checked to make certain they have adequate charge and will operate when needed. Power in the batteries can be saved by installing motion sensor cameras, but regular checking and maintenance is still required. If the batteries are not regularly checked the power source weakens, this in turn affects the distance that the signal is sent and can cause false alarms to occur.

The actual material the house is constructed of can also markedly affect the distance that an alarm signal is able to travel. Many wireless home security alarm system devices are designed to emit their signals quite a distance, often between 200 and 300 feet. Sometimes the signal has trouble penetrating very thick walls and this can significantly reduce the distance that the signal is able to travel, often resulting in a reduction of up to 50 percent of the designed distance. In these circumstances the wireless home security alarm system may still function correctly, however, its performance is hampered because the signal cannot effectively reach the central control receiver, which then reduces the system’s effectiveness.

If you are unsure as to which wireless home security alarm system you should install then it is advisable that you seek the advice of a professional security system consultant for guidance.
