| type | Power supply method | Wiring method | Things to note |
|---|---|---|---|
| Analog camera | DC12V power supply | Power cord + video cable (BNC connector) | Pay attention to polarity to prevent reverse connection |
| webcam | POE/DC12V | Network cable (T568B standard) | Category 5e or above wires |
| wireless camera | USB/battery | Only power cord required | Ensure WiFi signal strength |
2.Detailed wiring steps
(1)Preparation: Confirm the camera model and prepare the corresponding tools (cable crimping pliers, wire measuring instrument, etc.).
(2)Power wiring: Red is connected to the positive pole, black is connected to the negative pole, and fixed with insulating tape.
(3)signal transmission: The network camera is made of crystal head according to T568B standard, and the analog camera needs to be connected to a BNC connector.
(4)Test acceptance: After powering on, check the status of the indicator light and test the picture transmission quality.
3. Latest technology trends (updated in the past 10 days)
| Technical name | Application scenarios | Wiring changes | heat index |
|---|---|---|---|
| Smart AI camera | Face recognition monitoring | Additional data cable required | ★★★★☆ |
| 5G camera | Mobile surveillance scenario | Simplify wiring | ★★★☆☆ |
| Solar powered | Outdoor areas without electricity | No traditional wiring required | ★★★★★ |
4. Safety precautions
1. Be sure to turn off the power before wiring to prevent the risk of electric shock.
2. Outdoor installation requires the use of a waterproof junction box to ensure a protection level of IP66 or above.
3. According to the latest Cybersecurity Law, cameras in public areas need to be registered.
4. It is recommended to purchase regular products that have passed 3C certification to avoid the risk of circuit overheating.
5. Frequently Asked Questions
Q: How long can the network cable be connected?
A: The standard POE power supply distance does not exceed 100 meters. Extra long distances require the installation of a repeater.
Q: Will connecting the wrong wires burn out the camera?
A: Reverse polarity may damage the device. It is recommended to use a power adapter with a protection circuit.
Q: How to judge whether the POE power supply is normal?
A: You can use a line tester to check whether the 1/2/3/6 cores of the network cable have 48V voltage.
Through the above structured data and detailed instructions, I believe you have mastered the core points of camera wiring. If you encounter problems during actual operation, it is recommended to consult the equipment manual or contact the manufacturer for technical support.
