Before you actually invest in a security camera system, you need to think about what you'll be watching and what you need in order to watch it. The number of cameras you want is probably the first question that should come to mind. Are you focusing on one room in the house, or several different parts of the house? Will you need to monitor outdoor activity as well as indoor? If you're simply watching over one room, you'll probably need just one camera, but including more areas requires a bigger camera system. Below are the factors which you should consider before choosing a suitable security camera system.

Decide whether you want wired or wireless cameras.

 

Wired cameras offer a larger selection of cameras. Wired cameras might be trickier to install, and stray wires can hamper your attempts to be discreet but it has much better video quality than wireless cameras. Wireless cameras need to be powered at the camera location. In addition, they require a line of sight with no obstacles, which often poses an issue. Wireless cameras have more flexibility, but broadcasts from other devices such as cordless phones, wireless Internet and baby monitors can interrupt a wireless camera's signal.

• Reliability and video quality are the main reasons that you should use a wired camera. Wired cameras are powered back at the DVR location and only a single cable needs to be run from the DVR to each individual camera.


• You can expect a much longer lifespan and much higher quality with wired cameras.


• Obstacles are not an issue with wired cameras.

Understand the variety of security camera types available

 

The varieties of security camera types available are

• Infrared (IR) security cameras.


• Dome cameras


• Pro box cameras


• Hidden cameras

Consider the advantages of using an infrared (IR) security camera

 

This is a popular type of camera for both business and home

• Infrared Cameras produce high resolution colour video during the day.


• They are able to “illuminate the area” by automatically switching from colour to black and white.


• They provide a huge advantage in low light or no light situations.


• They can be weatherproofed and can withstand hot and cold temperatures without any additional camera housing.

Consider the advantages of a dome camera

 

The different styles of domes include indoor domes, outdoor domes, infrared domes, vandal proof domes and pan tilt zoom controllable domes.

 

• You can expect a clear colour high resolution picture with the dome camera.


• Most pan tilt zoom cameras are in a dome type housing as well.


• Professional “box type” cameras are used both indoor and outdoor with camera housing.

 

Consider the advantages of a pro box camera

 

These cameras are known for their high video quality. Pro box cameras are often found in supermarkets, banks, convenience stores, etc. This is also used as home wireless security camera system.

• Lenses can be changed based on the viewing angle and zoom that is required on the pro box camera.


• The lower the lux, the better the camera can see in complete darkness.

Consider the benefits of hidden cameras

 

These offer perhaps the highest degree of surveillance. Use a hidden camera if you do not want someone to know that there is a camera.

• The main disadvantage is that hidden cameras do not have infrared capabilities which limit their performance in low light.


• Many hidden cameras are not weatherproof, so they take are not as useful as infrared bullet and dome cameras when being used outdoors.
