When selecting the most effective security camera system easy for your house or business it is important to choose the right cameras that suit the unique 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 overall purpose cameras with more advanced specialized cameras if you want them. For example, you could have a situation where three entrances into your building have to be monitored with only average quality cameras and you intend to cover the parking lot with a camera that will read a license plate from 50 yards away. You can get 3 of the cameras that include the device 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 that the situation requires and determine which cameras best fit your needs. Ultimately this may permit you to most efficiently spend your money while getting the most effective surveillance coverage.
1) Will you need color or black and white cameras? Most packaged systems come with color cameras which are a lot better than black and white cameras at identifying valuable information on a suspect such as for example clothing or hair color. Typically black and white cameras are less costly and perform better at low light than color cameras. Color cameras actually switch to black and white in low light environments.
2) Which kind of night vision capability is required? A normal packaged color security camera can have an evening vision array of between 15 and 50 feet. High powered night vision cameras can have a range of 150 feet. Melbourne Security The main factor of determining the night time 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 might have different image quality requirements from each location. One camera may be installed at the front door only to buzz people in once they arrive for appointments. Another camera works extremely well to recapture license plates of cars driving through a large parking lot. These cameras have much different image quality requirements. In most cases the number of TV Lines (TVL) per inch is definitely an indicator of the image quality that is produced by the camera. General purpose packaged security cameras commonly have 400 - 420 TVLs. Cameras which 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 buy them. A lot of people fail to appreciate wireless security cameras still need power using a power cable. Wireless cameras use wireless technology to transmit a signal to a receiver which will be linked to a DVR or monitor, but many of them work with a power cable to plug right into a not far from outlet. You will find battery operated wireless security cameras, however the batteries have to be replaced quite often.
The image quality of wireless security cameras is usually inadequate because of interference. The farther away an instant camera is from the receiver and the more obstructions the signal must travel through the more the image quality is going to 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 ability requirements could be managed from exactly the same location while the DVR or monitor.
5) What elements are the security cameras planning to be exposed to? Most general purpose security cameras that can come in packaged systems can be used outdoors (as well as indoors) under normal conditions. If the cameras are likely to be exposed to extreme conditions such as for example hail or very high winds or there is a top likelihood of vandalism you might want to upgrade to cameras with heavier and stronger housings and mounting brackets.
