1. Important Safety Precautions
Please read this manual carefully before use and retain it for future reference. Failure to follow these instructions may result in damage to the product or personal injury.
- Operating Temperature: The camera is designed to operate within a temperature range of -30°C to 60°C. Do not use the camera in environments outside this specified range.
- Water and Dust Resistance: This camera has an IP66 dust-tight and water-resistant rating. While robust, avoid using it in extremely humid environments or locations where water ingress is possible to ensure normal operation.
- Power Adapter: The included power adapter is NOT waterproof and is for indoor use ONLY. Do not expose the power adapter to humid conditions. The power adapter's operating temperature range is -30°C to 45°C.
- Lens Placement: For optimal image quality, do not place the camera with its lens facing or next to reflective surfaces (e.g., glass windows, white walls). This can cause overexposure in close areas and underexposure further away, or produce washed-out images.
- Wi-Fi Signal: Ensure the camera is installed in an area with a strong Wi-Fi signal. Avoid installing it near microwave ovens or other devices that may interfere with Wi-Fi signals.
- Night Vision: A slight clicking sound may be heard when enabling or disabling night vision; this is normal and indicates the infrared cut-off filter is switching.
- Power Cable: If the power cable becomes damaged, contact the after-sales service team for replacement. Do not attempt to repair it yourself.
- Product Information: The product's nameplate information, including model and serial numbers, is located on the bottom of the device.

Figure D: Steps for mounting the camera. Figure E: Assembly of waterproof network port accessories.
3.5.1. Mounting Steps
- Positioning (Figure D-1): Stick the mounting template sticker on the desired wall location. Ensure the right side of the sticker is at least 50 cm away from any wall corner.
- Drilling (Figure D-1): Drill holes in the wall that align with the sticker's markings. The holes should be approximately 6 mm in diameter and 35 mm deep.
- Wall Plugs (Figure D-2): Insert the plastic wall plugs into the drilled holes.
- Wall-Mounted Installation (Figure D-3): Attach the wall mount to the wall by inserting screws through the mount and into the wall plugs. If the power cable is routed upwards, feed it through the groove in the wall mount first before securing the mount.
- Ceiling Installation (Figure D-4): Rotate the camera's base upwards, align it with the clip on the mounting bracket, and tighten the screw on the right side to secure it.
- Waterproofing Power Port (Figure D-5): Once the camera is securely mounted, wrap the waterproof tape around the power port connection to prevent water ingress.
3.5.2. Installation Cautions
- The mounting surface must be capable of supporting at least three times the total weight of the camera.
- To prevent potential injury, ensure the camera is securely fixed to the wall according to these instructions.
- Do not install the camera near heat sources such as outdoor air conditioning units, range hood outlets, or gas water heater outlets.
3.5.3. Installing Waterproof Network Port Accessories (Figure E)
These accessories enhance the network port's waterproof performance. They include a sealing ring, waterproof sleeve, stopper, and waterproof rear cover.
- Sealing Ring (Figure E-1): Place the sealing ring onto the camera's network port.
- Cable Assembly (Figure E-2): Thread the waterproof rear cover, stopper, and waterproof sleeve over the network cable in that order.
- Connection: Plug the network cable into the camera's port.
- Secure Assembly (Figure E-3): Screw the waterproof sleeve and sealing ring together. Then, screw the waterproof rear cover and waterproof sleeve together.
Note: Even if a network cable is not used, install these waterproof accessories to protect the port. Use a shielded network cable for best performance.
