Many packaged systems come with general purpose security cameras. Most vendors will enable you to replace the general purpose cameras with more advanced specialized cameras if you want them. As an example, you could have a scenario where three entrances into your building must be monitored with just average quality cameras and you intend to cover the parking lot with a camera that could read a license plate from 50 yards away. You will 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 recognize the special features that the situation requires and decide which cameras best fit your needs. Ultimately this may enable 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 much better than black and white cameras at identifying valuable details of 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 to black and white in low light environments.
2) What sort of night vision capability is necessary? A normal 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. SeriousSecurity CCTV The key factor of determining the night time 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 is 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 simply to buzz people in once they arrive for appointments. Another camera may be used to recapture license plates of cars driving via a large parking lot. These cameras have much different image quality requirements. Generally the amount of TV Lines (TVL) per inch is an indicator of the image quality that is created by the camera. General purpose packaged security cameras commonly have 400 - 420 TVLs. Cameras which have 480 - 520 TVLs gives a much 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 get them. Lots of people fail to appreciate wireless security cameras still need power using a power cable. Wireless cameras use wireless technology to transmit a sign to a receiver which is attached to a DVR or monitor, but many of them use a power cable to plug in to a close by outlet. You will find battery operated wireless security cameras, nevertheless the batteries must be replaced quite often.
The image quality of wireless security cameras is usually 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 said, there are many, many applications where wireless security cameras are ideal. Lots 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 exactly the same location as the DVR or monitor.
5) What elements will be the security cameras going to be exposed to? Most general purpose security cameras which come in packaged systems can be utilized outdoors (as well as indoors) under normal conditions. If the cameras will be exposed to extreme conditions such as for instance hail or quite high winds or there is a high likelihood of vandalism you might want to upgrade to cameras with heavier and stronger housings and mounting brackets.
