Summary of methods for selecting video surveillance

When we buy video surveillance, we will definitely be more troubled. How to choose the most suitable? Today I will teach you how to select video surveillance, the next seven steps:

step 1

Plan which areas you want to monitor. The outer door is a reasonable location and where the landscape invaders may lurk. In the house, consider the occupancy of the room monitor by children or elderly residents.

Step 2

Monitor the project with a video intercom system. Most include the use of infrared night vision waterproof camera lens 1. Looking for a camera tilt or pan display 1 to 1 door peephole can be a wider field. Many systems have two-way microphones.

Step 3

Consider, for example, motion sensors, dome (overhead) cameras and devices that automatically require time and date stamping snapshots for additional features when a visitor presses the doorbell - creating a record of who is on stage while you are not at home.

Step 4

Decide how you will view the image. The basic system consists of approximately $230 including a 4" (10 cm) black and white monitor and two cameras, upgraded ($350 or more, depending on the expansion) to get larger and / or color displays and more camera.

Step 5

The system links to one or more TVs and you can see who is outside the door without leaving your couch. Connect the recorder to record what the camera sees, with the PC network to view one or more camera images at the same time. An internet connection allows you to take images from any web-enabled device. The password system allows you to open the door and let the remote and remote guests or repairers.

Step 6

Create a closed circuit and join the webcam and TV to monitor the intercom system access. Each system - wired or wireless - has several transmission restrictions. Some receive signals only within a limited distance. The signals generally travel when they are farther in sight, and not the tourist route is through the wall.

Step 7

Select the auxiliary to press the respective indoor camera. In the baby's room, for example, looking for an infrared lens, the directional microphone activates the camera only when the baby is still crying at the mother. The network camera can be as low as 20 yuan, from 70 yuan basic indoor system to 100 yuan.

Summary: Now I have a clear understanding of the choice of video surveillance.
