Advice on Choosing a Right CCTV Camera
When facing too many choices, how to choose the right one will be a problem. But don’t worry; here are the main questions you can ask yourself when choosing the best suitable CCTV cameras for your home or business video surveillance system.
1. Where are you going to mount the security cameras or how many channels of home security camera DVR will you choose?
Then the answer can help you decide to choose how many cameras you have to buy. Choosing the appropriate location to install a security camera is vital to successfully deter intruders. The homeowner needs to assess the property to determine what type of surveillance cameras is required. Standard concerns include: entrances, exits, people who regularly visit, and the time of day and night visitors and family members come to the home. A homeowner also needs to decide if they want the security camera hidden or on display to discourage an entry attempt.
2. How long is the visible and night vision distance?
Usually, the visible distance of cameras can be up to 50’, 80’, 135’, etc.
3. How much the viewing angle?
Most video surveillance cameras are installed in one location permanently. For this case, fixed-focus lenses are the most cost-effective. If you want to be able to move your camera, variable focus lenses are adjustable, letting you change your field of view when you adjust the security camera. If you want to be able to move the camera remotely, you'll need a pan/tilt/zoom (PTZ) camera. On the other side, the price is much higher than the standard ones.
4. How much details of the security cameras image?
Of course, the resolutions of the Security Cameras are very important too. Generally speaking, 380TVL is low-end, 420TVL/480TVL is good for security work, and 540TVL or above is very high resolution. If you're going to want to see more detailed image, upgrading to a higher resolution CCTV camera is a good choice.
