# Hikvision camera by HTTP

## Overview

This template is designed for the effortless deployment of Hikvision cameras monitoring by Zabbix via HTTP and doesn't require any external scripts.

[`Sample device overview page`](https://www.hikvision.com/en/products/IP-Products/Network-Cameras/)

## Requirements

Zabbix version: 7.2 and higher.

## Tested versions

This template has been tested on:
- DS-I220 
- DS-I450

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.2/manual/config/templates_out_of_the_box) section.

## Setup

1. Set the hostname or IP address of the Hikvision ISAPI host in the `{$HIKVISION_ISAPI_HOST}` macro.

2. Set the user name and password in the `{$PASSWORD}` and `{$USER}` macros.

3. Change other macros according to your camera configuration if necessary.

### Macros used

|Name|Description|Default|
|----|-----------|-------|
|{$CPU.UTIL.CRIT}||`90`|
|{$HIKVISION_ISAPI_HOST}|<p>The hostname or IP address of the Hikvision ISAPI host.</p>|`<SET ISAPI HOST>`|
|{$HIKVISION_ISAPI_PORT}|<p>ISAPI port on device</p>|`80`|
|{$HIKVISION_MAIN_CHANNEL_ID}|<p>Main video stream ID</p>|`101`|
|{$HIKVISION_STREAM_HEIGHT}|<p>Main video stream image height</p>|`1080`|
|{$HIKVISION_STREAM_WIDTH}|<p>Main video stream image width</p>|`1920`|
|{$MEMORY.UTIL.MAX}||`95`|
|{$PASSWORD}||`1234`|
|{$USER}||`admin`|
