Hikvision DS-2CD2386G2H-IU 8MP AcuSense with microphone

A super cool camera from Hikvision

The surveillance camera comes from Hikvision’s AcuSense family, which means it is especially well suited to sending you phone notifications about people and vehicles. The camera is extra light-sensitive, so it delivers really good images in low light.

As you can see in the video below, the camera’s specialty is distinguishing between people, vehicles and uninteresting objects.

About the camera

The camera comes from Hikvision’s Turret series. These cameras are very robust and require very little maintenance. It is made of metal and is very durable, making it vandal-resistant. The camera is IP67 rated, which means it can withstand harsh weather and can be used both indoors and outdoors.
The camera has 3-axis adjustment, so it is very easy to mount, as it can be installed on vertical, horizontal and angled surfaces. 

Human and vehicle detection (Acusense)

Even though the camera is intelligent, it still needs some input from you. Once the camera is installed, you can choose between several types of "smart events", including "Intrusion detection", where a box is drawn in the image and when a target moves into the box and remains there longer than you allow (1-10 seconds), your "reaction" is triggered.
There is also line crossing, which detects whether a "target" moves across the line you have drawn. This can work in both directions or only one. It can, for example, be used on one-way roads to trigger an alarm if someone drives in the wrong direction, or on a driveway so you only get notified when people arrive, but not when they leave.

What is a reaction? The event triggered when a rule is violated is called a "reaction". Depending on the model selected, you have different options.
Most commonly used "reactions":

• Push notification on your mobile (receive an image directly on your phone of the target that broke the rule, with a link to direct playback in the app)
• Send email (use this function with caution, as the email provider may close your account on suspicion of spamming if too many images are sent)
• Flash white light
• Warning sound (siren or voice warning - there is also an option to record your own messages)*
• Alarm output (open a garage door, turn on lights, send a signal to your alarm system, integrate with IHC, etc.)

To have all functions, you need to choose the models where the model number ends in IS2U/SL

Which Acusense cameras can do what?

The model name tells you which functions the camera has if it ends with:

• DS-2CDXXX6G2H-I = Standard with infrared night vision
• DS-2CDXXX6G2H-IU= With infrared night vision and one microphone
• DS-2CDXXX6G2H-ISU = With infrared night vision, one microphone, alarm input and output
• DS-2CDXXX6G2H-IS2U/SL = With infrared night vision, dual microphone, alarm input and output, plus white strobe light and speaker

IP67 rated

The camera is IP67 classified. That means it can withstand both wind and weather. The camera can be used both indoors and outdoors.

• Dust-tight (6): Full protection against dust.
• Protected against immersion (7): Can withstand temporary immersion in water up to 1 meter deep for up to 30 minutes.

Supports micro-SD cards

The camera supports a micro-SD card up to 512GB
(SD card (memory card not included, but can be purchased here).

About the lens

The camera is available with several lenses, and the lens affects the FOV (Field Of View), or in Danish: viewing angle.
A 2.8 mm lens gives a horizontal FOV of 108.8°, vertical FOV of 56.4° and diagonal FOV of 134.3°
A 4 mm lens gives a horizontal FOV of 93.3°, vertical FOV of 47.2° and diagonal FOV of 114.2°

Mounting

The camera is very easy to mount and can be attached directly to a wall or to a ceiling/eave. A back box/bracket may be necessary if the connection cannot be placed behind the wall, ceiling or eave.
Under accessories you can see which brackets fit.

Power over Ethernet

Do like the professionals. POE means that only one cable is needed for the camera. The camera gets power through the network cable, typically from a recorder with built-in PoE, or from a POE switch.

ANR

Avoid losing recordings with AutomaticNetwork R eplenishment.
If there are network problems, the camera stores the recordings on an SD- card - and then sends them to the recorder when the connection is stable again.
