When selecting the very best security camera system possible for your home or business it is important to pick the right cameras that fit the initial needs of one's situation. You will find countless options and products features available.
Many packaged systems include general purpose security cameras. Most vendors will allow you to replace the typical purpose cameras with increased advanced specialized cameras if you want them. For instance, you may have a predicament where three entrances into your building must be monitored with only average quality cameras and you intend to cover the parking lot with a camera that may 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 has high powered zoom capabilities.
By walking through this security camera selection guide you will have the ability to identify the special features that your situation requires and decide which cameras best fit your needs. Ultimately this may allow you to most efficiently spend your money while getting the very best surveillance coverage.
1) Can you need color or black and white cameras? Most packaged systems include 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 less expensive 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 necessary? A typical packaged color security camera may have a night vision selection of between 15 and 50 feet. High powered night vision cameras can have a variety of 150 feet. SeriousSecurity CCTV The main factor of determining the night vision range is the amount of infrared LED's on the camera. Most general purpose security cameras include 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. One camera may be installed in front door only to buzz people in when they arrive for appointments. Another camera works extremely well to fully capture license plates of cars driving by way of 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 produced 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 produce a better image than CMOS cameras.
4) Wired vs. wireless? Understand the disadvantages of using wireless security cameras before deciding to get them. A lot of people fail to understand wireless security cameras still need power via 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 make use of a power cable to plug right into a not far from outlet. You will find battery operated wireless security cameras, however 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 energy requirements could be managed from the exact same location whilst the DVR or monitor.
5) What elements would be the security cameras going to come in contact with? 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 come in contact with extreme conditions such as for instance 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.
