Filed under: hardware, home technology, security, Tech Tips
I watched a show about robbery yesterday and the robber’s face was caught on the security cameras. The face on the camera became the best identification to catch the robber. Not only police, when the security cameras shot was broadcast on the local TV, then people who recognize the robber are helping the police to catch him. This is a casual event in criminal action and if we are checking to the police, we will find that security cameras are very helpful on catching criminal. Security cameras have become one of the mandatory accessories on security system. Therefore, if we have not completed our security system with security cameras, then make sure to start to choose the best one.
There are several types of security cameras that we can find in the market: night vision camera, dome camera, bullet camera, box camera, hidden camera, wireless and wired camera, and pan tilt zoom camera. Which one should we choose? Night vision camera can be used in the low light, so if we want to put security cameras on areas with dim light like backyard, garage, or some other spots, this camera type is recommended. Dome camera is another camera type that we can find. This camera is excellent for indoor usage and able to give sharp image. Bullet camera is one of the most popular security camera types. It is weatherproof, so it can be used for outdoor monitoring. We can also find bullet camera that completed with heater, so when we are using it on winter, there will be no fogging effect on the camera lens.
Box camera is another favorite security camera. The lens of this camera is adjustable and we can even use zoom version. This is a weatherproof camera and supported with cooling and heater fan. Wired and wireless surveillance cameras is an optional, but these cameras are having its own advantages and disadvantage, so make sure to learn about it further. The last type is pan tilt camera. It is served with remote control and the camera is full adjusted camera, but the price can be so expensive.
