When connected to the DMSS App, the camera can send push notifications to mobile phone.
Based on deep-learning algorithm, it can filter alarms triggered by irrelevant objects, and only focus on human and vehicle targets.
Now is even better with the latest 4K Active Deterrence IP Turret Camera with Red & Blue Strobe Light and Smart Illumination.
]]>In a nutshell, the lux is the metric unit for measuring the amount of light that falls on an object, and is the European equivalent of the British foot-candle (or lumen). Specifically, 1 lux equals the amount of light that falls on a one-square-meter surface that is one meter away from a single candle. 10 lux equals the amount of light produced by 10 candles one meter away.
Lux ratings are widely, and unfortunately, used to define low light performance, with the lower the lux rating, the stronger low light performance. Here's what this commonly looks like on manufacturer specifications: For instance, a camera with 0.02 lux is supposedly 'better' in low light than a camera with 0.05 lux.

Cameras needed light to generate an image. With too much light, the image was washed out, too little light and the image was too dark. If you had an environment with even lighting, the camera could adjust its iris opening size or its shutter speed to get the right amount of light. However, our offices and our homes have a wide range of lighting. The cameras had a tough challenge. If the camera restricted the amount of light it took in (to optimize for the bright areas) the lower light areas would be too dark. If it chose the opposite approach, optimizing for low light areas, the bright side would be washed out.
That's why the Wide Dynamic Range (WDR) technology came out for help. In a nutshell, it’s the ability to produce high quality images across a broad range of light levels. In other words, the light coming in from a window may be much more intense than the light by your coffee machine. True WDR cameras that work with a shutter speed technique and two images. The camera takes pictures of both areas and stitches them together, giving you a better-quality image.
True WDR cameras make a big difference in environments that have varying light levels. It is important to be able to capture the image of someone’s face as they walk into a dimly lit office from the bright sunlight outdoors. A subject’s hairstyle, clothing and details around him are crucial when studying the video surveillance footage.
With higher levels of light versus lower levels, you want a high performing WDR. Unfortunately, light measurements are not standardized and it’s the discretion of each manufacturer to determine what measurement to use. The generally accepted unit to measure in surveillance is the decibel (e.g., 58dB, 113dB, etc…). The higher the number, the better. The generally accepted dB level for a camera to be considered True WDR is 120dB.

The first two letters "IP" stands for "Ingress Protection" and is the International Protection Marking per IEC standard 60529. The most common use of an IP rating is how protected a product - such as a camera - is from a solid or liquid entering the product.
Following the letters "IP" are typically 2 digits which indicate the level of protection of the product. The first digit indicates the level of protection a product has from a solid - i.e. dust or a tool. The second digit indicates the level of protection a product has from liquid intrusion in certain volumes, pressures, or temperature.
For example, an IP camera that is IP67 rated will remain protected and fully operational in most industrial applications, including those where the camera is exposed to water spray, rain, debris, etc. The "6" indicates the sensor is dust tight. while the "7" indicates the sensor can be completely submerged in 1 meter of water for up to 30 minutes before the moisture penetrates the housing.
Please refer to the chart below as a quick reference for understanding IP ratings.
Solids |
Liquids |
1 Protected against a solid object greater than 50mm. | 1 Protected against vertically falling drops of water. |
2 Protected against a solid object greater than 12.5mm. | 2 Protected against vertically falling drops of water with enclosure tilted up to 15 degrees from the vertical. |
3 Protected against a solid object greater than 2.5mm. | 3 Protected against sprays of water up to 60 degrees from the vertical. Limited ingress permitted for three minutes |
4 Protected against a solid object greater than 1mm. | 4 Protected against water splashed from all directions. |
5 Dust protected. Limited ingress of dust permitted. | 5 Protected against jets of water. |
6 Dust tight. No ingress of dust. | 6 Water from heavy seas or water projected in powerful jets shall not enter the enclosure in harmful quantities. |
7 Protection against the effects of immersion in water between 1cm and 1 m for 30 minutes | |
8 Protection against the effects of immersion in water under pressure for long periods. |
