One, how to remove the peephole of the anti-theft door
The method for removing the peephole of a security door is simple: you can directly unscrew the peephole with your hand. You need to unscrew it on both the inside and outside of the door simultaneously. The peephole will open along the screw threads. Sometimes, the peephole is difficult to unscrew, requiring you to apply force while rotating it in the counter-clockwise direction. The screw threads of the peephole are long and may require repeated operations. Alternatively, you can use a specialized removal tool, such as a screwdriver, or use a coin to turn the peephole.
II. Installation of anti-theft door peephole cameras for monitoring.
1. Prepare tools and components: expansion plugs, screws, screwdrivers, small hammers, drills, and other necessary tools; check the size of the expansion plugs and self-tapping screws according to the pre-determined installation location, and test the fit of the support screws and camera base screws, as well as the condition of pre-embedded conduit connections. Ensure that the cables are unobstructed before proceeding with the installation procedure.
2. Remove the camera and, according to the pre-determined camera lens model and specifications, carefully install the lens. Ensure that the lens and CCD are not touched by hand, and confirm that it is securely fixed. After confirming, connect the power supply and connect the host or use a monitor or a small television to adjust the aperture and focal length.
3. Remove supporting structures, expansion plugs, screws, cone-shaped tools, small hammers, drills, and other necessary tools. Install the supporting structures according to the pre-determined positions. After verifying their stability, install the camera in the specified orientation.
4. If installing a protective cover is required, begin installation after Step 2. Open the cover's top and back panels; remove the metal plates and secure the camera; place the power adapter inside the cover; reassemble the top and back panels, arrange the cables, secure everything, and mount it on the support.
5. Insert the BNC connector of cable B into the receptacle of the cable, ensuring a secure fit.
6. Insert the power adapter's output plug into the camera's power socket and ensure it is securely connected.
7. Connect the other end of the cable to the control unit or monitor (TV), ensuring a secure connection.
8. Connect the monitoring host and camera power, and adjust the camera angle to the specified range using the monitor.
