Sound & Light Alarm

Smart Dual Illumination

Perimeter Protection


Current Active Deterrence Pain Points

Single Illumination Mode

At present, most products in the market only have IR light, and do not generate full-color image at night. Using white light at night can increase light pollution.

Limited Pickup Performance

Too much background noise causes interference; short pickup distance and limited mic function.

Poor Image Quality Under Low Illumination

Limited by hardware specifications, resulting to poor image quality at night.

Complicated Integration with Alarm System

It’s complicated to integrate with current alarm systems, which can affect user experience.

Detection Area for White Light

If the user sets the detection area for the white light, the white light won't turn on when there's is a target outside of the detection area, even if the target enters the monitoring area.

The white light turns on when the target enters the detection area. The alarm will focus on the designated area of interest, and is very effective for various solutions applications such as roadside, walk-way, or backyard.

Smart Dual Illuminators: The Most Comprehensive Illumination Method

Smart Dual Illuminators

Easily switch between full-color and IR mode


Smart Illumination Mode(default):  Switch between IR Mode and white light when target is detected.


IR Mode: Only IR illuminator is ON. It is suitable for scenes where supplementary white light is not required, thus reducing light pollution.


Warm Light Mode: Only the white light is ON. It is suitable for scenes that require color video footages.

Smart Illumination Mode: Switch Illuminators through AI:

Smart Illumination Mode Adopts a Deep Learning Algorithm to Detect Targets.


IR illuminator is on at night.


White light turns on when a target appears to record full-color images.


Siren and light turns on (Active Deterrence) to warn the target.


When the target disappears, white light turns off (PTZ back to preset), and IR illuminator turns back on.

Better Image: New Low-Light Image Experience

IR cameras on the market mostly have F1.6 aperture. ENS adopts F1.0 super large aperture which greatly improves the image quality.

IR Image with F1.6 Aperture

IR Image with F1.0 Aperture

Compared to the F1.6 Aperture, F1.0 Aperture presents a more detailed image: 1.The whole image is sharper and brighter. 2.Edge details are clearer.

Ecosystem: Arming/Disarming Through Alarm-in Port

The Active Deterrence 2.0 camera can be connected to traditional alarm systems. It offers one-tap arming/disarming through the alarm-in port. It allows usage of existing systems for alarm linkage and control, providing a better user experience.

Option 1: Arming/Disarming through an alarm button, which is connected with the camera’s alarm-in port.

Option 2: Arming/Disarming via the DMSS

AI Features: SMD 3.0

With the continuous in-depth application of SMD in the industry and constant optimization based on actual scenarios, we proudly launched SMD 3.0. Compared with SMD Plus, this new version offers more optimized features:

Reduced False Alarms

Through the upgrading of its AI capacities, false alarms caused by animals, leaves, lights, etc. are significantly reduced.

Longer Detection Distance

By constantly improving its AI capacities, the detection range of the same device has increased by as much as 50%.

Higher Detection Accuracy

Through the upgrading of its AI, the maximum detection accuracy for human and vehicle targets can reach up to 99%.

AI Features: Perimeter Protection

Powered by deep learning algorithm, ENS' Perimeter Protection technology can accurately recognize human and vehicle targets. In restricted areas (e.g. pedestrian area and vehicle area), false alarms in intelligent detection based on target type (e.g. tripwire, intrusion) are greatly reduced.

Accurate Detection False alarm rate: < 1%

Target Classification Focuses on human and vehicle

Quick Target Search Target search efficiency: ↑ 98%

Remote Monitoring Alarm push notification sending time: <1s
