When selecting the most effective security camera system feasible for your property or business it is essential to pick the right cameras that suit the initial needs of one's situation. There are countless options and products features available.
Many packaged systems have general purpose security cameras. Most vendors will enable you to replace the typical purpose cameras with more advanced specialized cameras if you need them. For instance, you may have a scenario where three entrances into your building have to be monitored with only average quality cameras and you want to cover the parking lot with a camera that could read a license plate from 50 yards away. You may get 3 of the cameras that come with the system 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 recognize the special features that the situation requires and determine which cameras best fit your needs. Ultimately this will enable you to most efficiently spend your cash while getting the most effective surveillance coverage.
1) Can you need color or black and white cameras? Most packaged systems have color cameras which are better than black and white cameras at identifying valuable details of a suspect such as for example 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 to black and white in low light environments.
2) Which kind of night vision capability will become necessary? A typical packaged color security camera could have an evening vision selection of between 15 and 50 feet. High powered night vision cameras may have a range of 150 feet. The main factor of determining the night time vision range is how many infrared LED's on the camera. Most general purpose security cameras have 15 to 30 LED's. Remember even color cameras record in black and white in low light situations.
3) What is the cheapest acceptable image quality from each location where cameras are installed? You may have different image quality requirements from each location. SeriousSecurity CCTV One camera might be installed at the front door only to buzz people in when they arrive for appointments. Another camera can be utilized to fully capture license plates of cars driving by way of a large parking lot. These cameras have much different image quality requirements. Generally how many TV Lines (TVL) per inch is definitely 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 will give a better image quality. Also, CCD cameras generally produce 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 realize wireless security cameras still need power using a power cable. Wireless cameras use wireless technology to transmit a signal to a radio that will be attached 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, but the batteries have to be replaced quite often.
The image quality of wireless security cameras is often inadequate as a result 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 will suffer. That being said, there are lots of, 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 energy requirements could be managed from the same location whilst 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 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 good winds or there is a top likelihood of vandalism you may want to upgrade to cameras with heavier and stronger housings and mounting brackets.
