• 1.Will you need color or black and white cameras?
  Most packaged systems come with color cameras
  which are better than black and white cameras at
  identifying valuable details of a suspect such as
  clothing or hair color. Typically black and white
  cameras are less expensive and perform better at
  low light than color cameras. Color cameras
  actually switch over to black and white in low
  light environments.
• 2. What type of night vision capability is
  needed? A typical packaged color security camera
  will have a night vision range of between 15 and
  50 feet. High powered night vision cameras can
  have a range of 150 feet. The main factor of
  determining the night vision range is the number
  of infrared LED's on the camera. Most general
  purpose security cameras come with 15 to 30
  LED's. Remember even color cameras record in
  black and white in low light situations.

• 3. What is the lowest acceptable image quality
  from each location where cameras are installed?
  You may have different image quality requirements
  from each location. One camera may be installed
  at the front door only to buzz people in when
  they arrive for appointments. Another camera may
  be used to capture license plates of cars driving
  through a large parking lot4. Wired vs.
  wireless? Understand the disadvantages of using
  wireless security cameras before deciding to
  purchase them. A lot of people fail to realize
  wireless security cameras still need power via a
  power cable. Wireless cameras use wireless
  technology to transmit a signal to a receiver
  which is connected to a DVR or monitor, but most
  of them use a power cable to plug into a near by
  outlet. There are battery operated wireless
  security cameras, but the batteries need to be
  replaced quite often.

• The image quality of wireless security cameras is
  often inadequate because of interference. The
  farther away a wireless camera is from the
  receiver and the more obstructions the signal
  must travel through the more the image quality is
  going to suffer. That being said, there are many,
  many applications where wireless security cameras
  are ideal. Many of the wired systems available
  have cabling that supplies both power and video.
  This means all the power requirements can be
  managed from the same location as the DVR or
  monitor.
• 5.What elements are the security cameras going to
  be exposed to? Most general purpose security
  cameras that come in packaged systems can be used
  outdoors (as well as indoors) under normal
  conditions. If the cameras are going to be
  exposed to extreme conditions such as hail or
  very high winds or there is a high likelihood of
  vandalism you may want to upgrade to cameras with
  heavier and stronger housings and mounting
  brackets.
