Installation Requirements

The horizontal distance between camera and monitoring target is d(m), the camera installation height is h(m), depression angle of camera is α(degree) (it is the included angle between the camera monitoring direction and horizontal surface). You can refer to the following parameter table:

Parameter	Recommended value	Range
Height h(m)	2.5	2~3
Horizontal distance d(m)	6	4~20
α(degree)	≤15	10~15

If the actual situation fails to meet the settings recommended in the table above, you can refer to the table below. Select the most suitable parameter configuration if it can guarantee that the face pixel is more than 150 x 150 (it can reach 200 x 200 ideally) in 1080P.

Height(m)	Horizontal distance(m)
2	4~20
2.25	5~20
2.5	6~20
2.75	7~20
3	8~20

Installation Testing

1. Select test point (it is recommended to select the test point where there is good light, try to avoid backlight and sidelight), lay a camera in the location which is d meters horizontally away from the test point, the fixed height is h meters. (please select d and h according to the table above)

2. Installation person A stands in the test point, look ahead horizontally, installation person B will adjust the IPC; Adjust the camera angle, monitoring range, focal length until it meets the following requirements:

a) The human face is in the center of the image, and it is clear.

b) Make sure the width of the face is more than 150 x 150 pixel in 1080P resolution (take snapshot via IPC web, use paint tool to check image pixel, the distance between the center of both eyes is required to be more than 50 pixels.)

3. Make sure the requirements above should be satisfied, and then fix the camera and lens. The installation person A passes the monitoring point from far to near, installation person B checks the monitoring image to make sure it can acquire front, clear face whose width and height is bigger than 150 pixels when person A is passing monitoring point, then it means the installation is successful. The ideal monitoring effect is shown in the above image.

IVS Best Practices

To assess issues with IVS compatibility between the camera and NVR, please update both devices to the most current firmware and factory reset the NVR, and use the hard reset button to reset the camera.

Video Instructions

Step by Step Instructions

1. Click “Enable”.

2. Click face enhancement to enhance the face image display.

3. Select max and min size, draw max and min target for target filtering. This step is to filter target, which can’t be operated under default status.

4. Activate record, alarm, email and snapshot according to the requirements.

5. Target filter can set max target and min target, which means it can detect max and min target.

6. Click ok to complete settings.
