Hikvision DS-2CD2346G2H-IS2U/SL 4MP AcuSense Turret with microphone and speaker

One of the coolest and smartest cameras on the market

This surveillance camera is part of Hikvision’s AcuSense family, which means it’s especially well suited to sending you notifications on your phone about people and vehicles. 

Watch the video showing how it works

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 are cameras that 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 axes and is therefore very easy to install, as it can be mounted 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 be set for both directions or just one. It can, for example, be used for one-way roads, so an alarm is triggered if someone drives the wrong way, or at a driveway so you only get a notification when people arrive, not when they leave.

What is a reaction? The event that is triggered when a rule is violated is called a "reaction". Depending on the model chosen, 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 mail provider may close your account for suspected spamming if too many images are sent)
• Flash white light
• Warning sound (siren or voice warning - it is also possible to record your own messages)*
• Alarm output (open a garage door, switch on lights, send a signal to your alarm system, interact with IHC, etc.)

To have all functions, choose the models where the model number ends with IS2U/SL

Which Acusense cameras do what?

The model name tells you which features 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, as well as white strobe light and speaker

IP67 rated

The camera is IP67-rated. This means it can withstand all kinds of weather. The camera can be used both indoors and outdoors.

• Dust-tight (6): Full protection against dust.
• Waterproof 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 can take 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 100°, vertical FOV of 55° and diagonal FOV of 120°
A 4 mm lens gives a horizontal FOV of 81°, vertical FOV of 45° and diagonal FOV of 95°

Installation

The camera is very easy to install and can be mounted directly on a wall or in a ceiling/eave. A back box/bracket may be required 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.
