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 tough, 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 is 3-axis and therefore very easy to install, as it can be mounted on vertical, horizontal, and sloped surfaces.

People and vehicle detection (AcuSense)

Although 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 have allowed (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 both directions or only one direction. It can, for example, be used for one-way roads so that an alarm is triggered when driving in the wrong direction, or in 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 mobile (have an image of the target that broke the rule sent directly to your phone, with a link to direct playback in the app)
• Send email (this function should be used with caution, as the email provider may close your account for suspected spamming if too many images are sent)
• Flash white light
• Warning sound (siren or voice warning - there is also the option to record your own messages)*
• Alarm output (open a garage door, turn on lights, send a signal to your alarm system, interaction with IHC, etc.)

To have all features, you must choose the models where the model number ends with IS2U/SL

(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 100.2°, vertical FOV of 54.7° and diagonal FOV of 119.7°
A 4 mm lens gives a horizontal FOV of 81.1°, vertical FOV of 44.7° and diagonal FOV of 94.6°

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.
