How to Choose a CCTV System
- 1). Compare camera options. Standard CCTV cameras resemble hand-held camcorders, and are mounted to walls or ceilings using a mounting bracket. Small dome cameras help obscure the camera lens from subjects under surveillance, and are less obtrusive if aesthetics are the primary concern. Hidden cameras can be fit inside many different types of objects, but may not provide the best picture quality or viewing angle.
- 2). Consider when the system will be used. If you will only use the camera during the day, a standard model will suffice. For users who need to tape nighttime activities, an infrared or "True Day/Night" camera will provide a better viewing experience. According to the IC Security Company, "True Day/Night" models provide the best possible images when lighting is limited.
- 3). Evaluate whether you'll need a black and white or color CCTV system. According to "Video Surveillance Guide," black and white cameras cost less than color systems, and also provide better light sensitivity. Color CCTV units cost more, but can provide more details about the object under surveillance.
- 4). Match the display quality of each system to your needs. According to IC Security Company, CCTV image quality is measured using television lines, or TVL. The most affordable CCTV systems have a TVL of around 350, while mid-range units have a TVL between 450 and 480. The most expensive and highest quality systems have a TVL ranging from 550 to 580.
- 5). Ask about monitor options. Some CCTV systems allow viewers to observe camera activities using a television set, while others require a computer monitor. Some specialized systems will only work with special high-security monitors. For home use, it's often easier and more economical to find a system that works with your TV or computer.
- 6). Inquire about remote access. Many CCTV users want the option of viewing camera activities from remote locations. This allows parents to use nanny cams while at work, and allows business owners to observe employees from home or other branch offices. Look for a CCTV system with networking ports or a wireless network built-in if you are interested in remote access.
- 7). Decide how the system should be operated. CCTV cameras typically feature either continuous operation or motion-sensors. Homeowners may choose motion-activated cameras so they don't waste recording capacity on long periods on inactivity. In a business, continuous recording is often required to maintain sufficient security.
- 8). Check on available storage space. For CCTV systems with built-in storage, capacity is often fairly low. Users will need to remove video recording files frequently and save them to another source, if required. Systems with a large amount of storage space allow users to easily save files for a longer period of time without transferring them to other media sources.
