With the development of society, the use of surveillance cameras has become more and more widespread, and we can see various types of security cameras in our daily lives. Faced with different forms of video surveillance products, how can we correctly choose a surveillance camera that suits our needs? Where do they differ? What are the important points to pay attention to when installing surveillance cameras? Below we will introduce some points that we frequently encounter when selecting and installing surveillance products.

Choosing a security camera:

If you need to monitor a 20 square meter room, OHWOAI recommends choosing a camera with a 2.8mm wide-angle lens, which can cover the entire area.

If your surveillance range is within 30 meters, you can choose OHWOAI's OHWOAI-300WXDT camera. If your surveillance range is more than 30 meters, especially if you need night surveillance, we recommend OHWOAI's 10-inch OHWOAI-10inch-new2-500 (2-camera wireless security camera set) and make sure the infrared light is at a sufficient distance. If your surveillance range is more than 80 meters, we recommend OHWOAI's OHWOAI-POE5008 (8-camera security camera set).

If you need to monitor more than 60 meters away, you will need to add an additional light source to the monitored area. OHWOAI's security camera remote monitoring security camera set can be expanded up to 10 units. This is because the nighttime monitoring distance of an infrared camera is usually half the nominal distance.

If you need to monitor the outside of a convenience store, choose a 30 meter thermal camera and pair it with a 2.8mm or 3.6mm lens to ensure key areas are covered.

If you want to monitor a 10 meter corridor, we suggest you choose a 30 meter infrared camera with a 3.6mm lens; for a 15 meter corridor, you can choose a 30 meter infrared camera with a 6mm lens; while for a 25 meter corridor, you can choose a 30 meter infrared camera with an 8mm lens, meeting different needs.

For gatekeeper and security surveillance in residential areas, you can choose a 50 meter infrared camera and pair it with a 6mm or 8mm lens, while for gun cameras you can consider a 6-15mm magnification lens.

If you need to install surveillance equipment on the highway, you can choose lenses with 5-100 meters magnification and automatic aperture function to meet the requirements of different surveillance distances.

Generally, the lower the camera is installed, the better the surveillance effect, and it is recommended to choose a security camera, especially since outdoor cameras are easily damaged, which will ensure the security of your device.

If you need to photograph car license plates, it is recommended to choose a wide dynamic camera, in this case the height of the camera should not exceed 1.2 meters.

For the camera used by teachers during teaching activities, you can choose a 480 line gun camera, pair it with a 6-60mm lens, and install the camera at the back of the classroom to protect the privacy of students and teachers.

Surveillance camera installation:

For indoor monitoring, you can choose OHWOAI's OHWOAI-BJQIUJI camera, because the indoor light is relatively uniform, while for outdoor monitoring, OHWOAI's OHWOAI-BJQIUJI camera is more suitable.

If your surveillance standards are high, you can choose OHWOAI-400solar4-1TB (4-camera wireless security camera set) especially from OHWOAI to get higher resolution image quality.

If you need remote night surveillance, choose an infrared waterproof camera, infrared speed dome camera or infrared high-speed dome camera with adjustable focal length, and combine an auxiliary light source if necessary to ensure the surveillance effect.

If you need to monitor remotely and the lighting conditions are good, you can simply choose the normal camera core, a constant speed dome camera or a high speed dome camera.

When installing the camera, avoid backlit situations to ensure clearer surveillance images.

Whatever your needs, choose the right surveillance camera based on your specific situation and install it properly to ensure your safety and security needs. OHWOAI provides surveillance cameras and equipment for different customer needs and can meet your demands.
