When selecting the best security camera system possible for your property or business it is important to pick the proper cameras that fit the initial needs of one's situation. You can find countless options and products features available.
Many packaged systems include general purpose security cameras. Most vendors will enable you to replace the overall purpose cameras with increased advanced specialized cameras if you want them. For instance, you may have a scenario where three entrances into your building have to be monitored with just 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 are included with the machine then replace the fourth with a camera that's 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 decide which cameras best fit your needs. Ultimately this will enable you to most efficiently spend your hard earned money while getting the best surveillance coverage.
1) Do you want to need color or black and white cameras? Most packaged systems include color cameras which are a lot better than black and white cameras at identifying valuable details of a suspect such as clothing or hair color. SeriousSecurity CCTV Typically black and white cameras are less costly and perform better at low light than color cameras. Color cameras actually switch over to black and white in low light environments.
2) Which kind of night vision capability is needed? A typical packaged color security camera may have an evening vision array of between 15 and 50 feet. High powered night vision cameras can have a range of 150 feet. The key factor of determining the night time vision range is how many 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'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 might be installed in front door simply to buzz people in when they arrive for appointments. Another camera may be used to recapture license plates of cars driving through a large parking lot. These cameras have much different image quality requirements. Broadly speaking how many TV Lines (TVL) per inch is an indicator of the image quality that's produced by the camera. General purpose packaged security cameras commonly have 400 - 420 TVLs. Cameras that have 480 - 520 TVLs gives 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 appreciate wireless security cameras still need power via a power cable. Wireless cameras use wireless technology to transmit a signal to a recipient which can be linked to a DVR or monitor, but many of them make use of a power cable to plug right into a not far from outlet. You can find battery operated wireless security cameras, but the batteries have to be replaced quite often.
The image quality of wireless security cameras is usually 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 probably 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). This implies all the power requirements can be managed from exactly the same location because the DVR or monitor.
5) What elements will be the security cameras planning to come in contact with? 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 come in contact with extreme conditions such as hail or very good winds or there's a higher likelihood of vandalism you might want to upgrade to cameras with heavier and stronger housings and mounting brackets.
