When selecting the best security camera system possible for your property or business it is essential to choose the best cameras that suit the initial needs of your situation. You will find 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 want them. As an example, you could have a situation where three entrances into your building must be monitored with just average quality cameras and you wish to cover the parking lot with a camera that can read a license plate from 50 yards away. You can get 3 of the cameras that are included with the machine then replace the fourth with a camera that has high powered zoom capabilities.
By walking through this security camera selection guide you will have the ability to spot the special features your situation requires and determine which cameras best fit your needs. Ultimately this will permit you to most efficiently spend your cash while getting the best surveillance coverage.
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 information on a suspect such as for instance 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 sort 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 might 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's the cheapest 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 in front door simply to buzz people in if they arrive for appointments. Another camera can be utilized to capture license plates of cars driving via a large parking lot. These cameras have much different image quality requirements. Melbourne Security In most cases the number of TV Lines (TVL) per inch is definitely an indicator of the image quality that's created by the camera. General purpose packaged security cameras commonly have 400 - 420 TVLs. Cameras which have 480 - 520 TVLs will give a better image quality. Also, CCD cameras generally make a better image than CMOS cameras.
4) Wired vs. wireless? Understand the disadvantages of using wireless security cameras before deciding to buy them. Plenty of people fail to realize wireless security cameras still need power with a power cable. Wireless cameras use wireless technology to transmit a sign to a recipient which is attached to a DVR or monitor, but a lot of them use a power cable to plug in to a not far from outlet. You will find battery operated wireless security cameras, but the batteries must be replaced quite often.
The image quality of wireless security cameras is usually inadequate due to 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 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 (aka siamese cabling). This means all the energy requirements can be managed from exactly the same location while the DVR or monitor.
5) What elements are the security cameras likely to come in contact with? Most general purpose security cameras that can come in packaged systems may be used outdoors (as well as indoors) under normal conditions. If the cameras are going to come in contact with extreme conditions such as for instance hail or quite high winds or there is a higher likelihood of vandalism you may want to upgrade to cameras with heavier and stronger housings and mounting brackets.
