If you look around today you will undoubtedly see security cameras just about everywhere that you go. You will see these surveillance devices installed inside and outside of many businesses and they are also becoming commonplace in residential homes. You must ask yourself what the point is to all of these individuals spending money on these elaborate means of security.
The answer is simple. It is because they work to deter crime. Criminals that have been caught have given us insight as to how they commit their crimes and what homes and businesses that they target. Most tell us that if they see a potential target that has security cameras or an alarm system then they will move on to the next place that does not have any protection.
The expense of a home security camera system is usually the most common objection to having a system installed. The prices have come down considerably and if you install the system yourself you can save hundreds if not thousands on the installation.
Wired Home Security Cameras
When you are considering an installation of a home security system you must first plan the layout of your cameras. It is extremely important to plan ahead. You may look at your home and think at first glance that you only need 4 cameras. You could cover the front door, back door and each side of your home. You must be aware of the expansion capabilities of the system that you purchase. If you decide at a later date to upgrade and add more cameras it could be expensive because you will possibly have to purchase a different DVR. Your DVR will come with a number of inputs that the cameras will plug into. They typically come with 4, 8 or 16 channels or inputs. If you buy a 4 channel DVR and want to add a 5th camera at a later date you will have to buy an 8 channel dvr. It is usually better to purchase the next level up for your DVR. This way you can always add additional cameras at any time. I have had many customers that add cameras when they see how great they operate so I always make them consider the options before making a final decision on the dvr size.
Wireless Home Security Cameras
Wireless cameras have come a long way as far as reliability and picture clarity. They were subject to a lot of interference which reduced picture resolution. That was then and this is now. I recommend going with a wireless cameras in more installations than a wired solution. This is particularly true for the DIY camera installation. Manufacturers are focused on making the installation of these products very user friendly. Cameras and camera systems were always pricey but the labor cost was always the most expensive. If you can read instructions and handle a screwdriver you can install your own system. The customer support for most of these systems is very good. They know that in order to sell these units that they have to be there for the DIY people and they are doing a very good job of it.
Home Security DVR
A DVR is a recording device for a security camera system. These units supply the power for the cameras. The main difference in DVR unit is in the number of cameras that can be plugged into the unit. The typical number of inputs is 4, 8 and 16. You might think that the physical size of the unit would be much larger when selecting more inputs but the size remains pretty much the same between units. The DVR records and plays back all of your video. It has many different selections as far as picture quality and when and where to record the video. You can select which cameras to record and whether they record all of the time or only when they detect motion. Be aware that many of the wireless security camera systems do not record the video. Some will send you a still shot of video when motion is detected but in many cases the video is meant to be monitored in live mode only.
