A surveillance system is basically a series of security cameras connected to a monitor and recording system. It helps to facilitate the watching of an area remotely. These days, having a surveillance system helps homeowners and business owners to keep track of their property. It helps them monitor things without physically being there. In fact, surveillance systems are also useful for parents who want to keep an eye on how their babysitter treats their kids. Ultimately, a surveillance system is a security measure utilized by homeowners and business owners because it is able to provide them with asset protection.
If you are planning to build a surveillance system, you need to take into consideration a multitude of factors. One such factor would involve your security requirement. How many security cameras do you need and what types of feature should they have, such as wireless, night vision capability and motion sensors. Another factor is the recording device. This involves whether all cameras are recording every moment, or whether some are set to record 24/7 while other are set to record when motion has been detected. Budget is also a factor that should be carefully considered. This is because no matter how high risks your security requirements are, if you don’t have the budget purchase them, then do not aim for models and pieces that are beyond your budget. Perhaps another factor that can be included in here is the difficulty of installation – as to whether or not you need to hire a professional to do the installation for you, or do the installation yourself.
In order to have a successful surveillance system, you will need to have a quality set of security cameras. This is an essential item when building your surveillance system because they are the devices that are responsible for physically capturing the events that goes on in an area being monitored. The number of rooms and key strategic areas you want to monitor will help determine the number of security cameras you need. Knowing the areas you want to monitor will also help you in determining the type of lens suitable for your security camera, whether it is for indoor or outdoor use along with the type of angle needed for that for that area.
The truth is, these days you will find a good variety of security cameras with different features. Understanding the different types of security cameras is therefore essential as this will help you in choosing right one for the right area to monitor. When choosing a security camera for an area, you should first denote whether the area to be monitored is indoors or outdoors. If the location is outdoors, you may want to consider the weather available in your region so you can acquire a security camera that is ideally weather proof. For example, if you live in an area where it is hot in the summer but snows during the winter, then the type of outdoor security camera you might want to get should have a housing that has a heater and blower to prevent the camera from accumulating snow or freezing and thus maintain a good operating condition even on heavy snow situations. In addition, if the security camera is continuously outdoors, you may want to consider having a vandal proof enclosure to ensure your camera is safe from vandals.
Another option to keep in mind for your security camera would be its type of lens. If your security camera is capable of zooming, you might want to consider varifocal lens that have large focal lengths. However, if your camera has a fixed zoom with only a static area being covered, you would likely need a fixed focal length or monofocal lens. In short, a varifocal lens can be adjusted with different focal lengths, while a monofocal lens has a fixed focal length. Both type of lens can be fitted with either an auto iris or a manual iris. The use of auto irises are highly suggested because they are able to automatically adjust their opening based on the light conditions to get clearer images, as manual irises, as the name suggest, need to be adjusted manually.
Another key component needed for a successful surveillance system is the ability to record the video footage captured by the security cameras. This is basically a key feature which makes surveillance systems sought after because the recorded video they take can serve as undeniable video evidence against perpetrators. These days, the recording systems used by surveillance systems are DVRs. In the past they used VTRs which where messy and unreliable. However, thanks to technological advancements, DVRs were created. There are a variety of DVRs sold in the market these days and you need to figure out which type is more suitable for you. This is because DVRs also act as the video receiver for the security cameras and every DVR models can handle only a predetermined number of video channels.
In addition to security cameras, lenses, and DVRs, you may also want to consider some items in your list such as a monitor, wirings, power cables, mounts and brackets. Although these are not the main components of a security system, they nevertheless help to compete it.
Once all of your equipments are complete and are at hand, you can try to install the system yourself or hire an industry professional to do it for you. It is important that you do not take this decision lightly, especially if you are installing a very complex system such as a multiple DVR system along with a multitude of security cameras. However, if you are installing a wireless system that consists of just 4 wireless security cameras, then you can try installing the system yourself.
The truth is making a decision whether to install the system yourself, especially if you are techie, can sometimes be difficult as you are likely to understand the principle behind the installation of the surveillance system itself. The only problem often involved with installing the system yourself is the lack of the necessary tools needed.
