When selecting the best security camera system easy for your house or business it is important to pick the right cameras that fit the unique needs of your situation. There are countless options and products features available.
Many packaged systems come with general purpose security cameras. Most vendors will permit you to replace the typical purpose cameras with an increase of advanced specialized cameras if you need them. As an example, you may have a scenario where three entrances into your building need to be monitored with just average quality cameras and you want to cover the parking lot with a camera that can read a license plate from 50 yards away. You may get 3 of the cameras that are included with the system then replace the fourth with a camera that's high powered zoom capabilities.
By walking through this security camera selection guide you will be able to spot the special features your situation requires and determine which cameras best fit your needs. Ultimately this may permit you to most efficiently spend your money while getting the best surveillance coverage.
1) Can you need color or black and white cameras? Most packaged systems come with color cameras which are much better than black and white cameras at identifying valuable information on a suspect such as clothing or hair color. Typically black and white cameras are more affordable 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 becomes necessary? A typical packaged color security camera could have an evening vision array of between 15 and 50 feet. High powered night vision cameras can have a selection of 150 feet. The key factor of determining the night vision range is the amount 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's the best acceptable image quality from each location where cameras are installed? You could have different image quality requirements from each location. One camera might be installed at the front end door only to buzz people in once they arrive for appointments. Another camera may be used to fully capture license plates of cars driving via a large parking lot. These cameras have much different image quality requirements. Melbourne Security Broadly speaking the amount of TV Lines (TVL) per inch can be an indicator of the image quality that is created by the camera. General purpose packaged security cameras commonly have 400 - 420 TVLs. Cameras that have 480 - 520 TVLs can give a much better image quality. Also, CCD cameras generally create a better image than CMOS cameras.
4) Wired vs. wireless? Understand the disadvantages of using wireless security cameras before deciding to get them. Plenty of people fail to understand wireless security cameras still need power with a power cable. Wireless cameras use wireless technology to transmit a signal to a radio which can be connected to a DVR or monitor, but a lot of them use a power cable to plug right into a near by outlet. There are battery operated wireless security cameras, nevertheless the batteries need to be replaced quite often.
The image quality of wireless security cameras is often inadequate as a result 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 will suffer. That being said, there are many, many applications where wireless security cameras are ideal. Most of the wired systems available have cabling that supplies both power and video (aka siamese cabling). What this means is all the ability requirements can be managed from the same location as the DVR or monitor.
5) What elements are the security cameras likely to be exposed to? Most general purpose security cameras which come in packaged systems may 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 good winds or there's a high likelihood of vandalism you may want to upgrade to cameras with heavier and stronger housings and mounting brackets.
