How to Setup Audio Detection with Your Security Camera System | 3G Mobile CCTV

Audio Detection is a feature that can be a very reliable way to capture a conversation or other important sounds that need to be recorded. It allows a security camera with a built-in microphone or audio input to trigger recording when sound is detected. You no longer have to rely on video-based motion detection to try and capture audio of an event and missing out on everything that was said.

With audio detection you can even capture video/audio when persons are conversing outside the cameras field of view, but near enough to activate audio detection. You can finely adjust the sensitivity and threshold settings to decrease your storage needs. In this guide, we show you how to setup and use audio detection with surveillance cameras purchased from CCTV Camera World.

With Audio Detection you can set up alerts and triggers like you would for traditional video detection. Email, buzzer, and alarm upload features are all supported when an audio event is detected allowing you to be notified immediately. This can save you a lot of time of having to sift through hours of continuous audio/video looking for a small segment of conversation or sound.

What do you need for Audio Detection to work? An IP security camera with built-in microphone Or an IP camera with audio input for a security camera microphone (microphone not included) A compatible NVR system that supports audio detectionHow is the Audio Detection setup? 1.

Mount The Camera or Microphone to Capture Good Sound and Picture It is important that you mount the camera strategically to capture good video and audio. This includes making sure that the camera or microphone is not near constant background noise that will trigger audio detection and create false alerts. Conversely ensure that the audio device is close enough to capture the desired recording.

Keep in mind that sensitivity settings can be adjusted and fine tuned for most applications. Mount the camera pointed in a direction and angle where the sound will be coming from to avoid missing out on important footage. 2.

Importing Electronic Cigarettes from ChinaElectronic cigarettes are one of the few products that could be considered a home grown product in China. Since the first units rolled off the assembly lines in Shenzhen about 10 years ago, the electronic cigarettes have presented itself as a serious alternative to smokers that still want to take a puff now and then.However, e-cigarettes are still a topic of high level controversy, and regulations are still on the drawing board in both the US and EU.

The product is also lethal if not manufactured according to the relevant safety standards. Keep reading and we explain why. Electronic Cigarette Manufacturers in China Theres only one place in the world to go if youre looking for electronics, the Guangdong province.

Roughly 87% of the Electronic cigarettemanufacturers based here. Of these, the majority isbased in Shenzhen, a city bordering Hong Kong. But there are also quite a few suppliers located in Dongguan, Huizhou and Zhongshan all of which are also based in Guangdong province.

The industry jump started in 2010 and 2011 when hundreds of new suppliers starting manufacturing and trading (thats two different things) electronic cigarettes. This was before most western government had yet reacted to the influx of this, still controversial, product. Ill get to that in a bit.

A lot of suppliers caught on this trend and started trading electronic cigarettes, rather than manufacturing the product themselves. If you browse a site youll quickly notice that most suppliers are mere traders, with very little registered capital (ranging from RMB 30,000 to 100,000). Stay away from these suppliers.

They cant offer a better price. They can rarely offer smaller volumes and certainly not smaller volumes of electronic cigarettes that are compliant with EU andUS product certification standards. What they can offer is an extra, non-transparent, layer between you and the actual manufacturer.

A manufacturer you know nothing about. Components and Product Specifications Theres no universal definition of good quality. Instead, you need to know what defines good quality.

As with every product, there are certain features and parameters thatdefines the quality standardof an electronic cigarette. To begin with, there are 4 main categories of electroniccigarettes:1. Rechargeable Electronic Cigarettes 2.

Disposable Electronic Cigarettes (Non-Rechargeable) 3. E-Go Electronic Cigarettes 4. Personal Vaporizers Product specifications vary between the different types of electronic cigarettes.

For example, you dont need to bother with E-liquid cartridges if youre purchasing Disposable Electronic Cigarettes. But there are still a number of common quality factors that buyers should take into consideration when selecting a product: Cartridge Puffs: 200 500 Cartridge Capacity: 1.X ml Child-proof spring switch: Yes / No Body material: Mouthpiece material: LED: Yes / No Charger type: USB Battery Capacity: XXX mAh Weight: XXg Working voltage: 3.

X 3.X VBatteryMost suppliers can offer batteries of different capacities. Its a critical component, since the number of puffs is limited not only by the E-liquid, but also the battery capacity.

The relation between the battery capacity and the number of puffs is something like this: 650mah: 600-650 puffs 900mah: 800-850 puffs 1100mah:1000-1050 puffs Theres also a limit to the battery life. However, the battery shall be rechargeable at least 300 times. Charger Most suppliers offer both USB chargers and Power socket chargers.

Id go for the USB charger. The voltage in a power socket is much higher than the voltage in a USB socket (around 5 V). An overloaded power socket charger can cause personal injury and outbreak of fire.

Ive seen it happen. On the other hand, an overcharged USB is likely to result in little more than a voltage drop or cut. That wont kill anyone or burn down a house.

E-liquidsThe E-liquid, or E-juice, is the active substance in the electronic cigarettes and usually contains the following: Propylene glycol Vegetable glycerin Nicotine Flavorings However, theres no set standard of what substances E-liquid shall contain, not to mention the content of each substance. This is also a current topic of debate among regulators around the world, particularly in the European Union and United States.In the European Union, the legal situation is more fragmented.

So far, theres no EU wide product safety standard that applies specifically to electronic cigarettes. However, EU states have implemented their own regulations. As of today, its legal to import and sell electronic cigarettes and liquids with nicotine in the following EU countries: United Kingdom Germany Italy Poland Ireland Latvia Lithuania Still, electronic cigarettes are still a topic of debate and further regulations are to be expected.

This post could be outdated two weeks from now, so make sure youread up on the current regulationsbefore you import electronic cigarettes or e-liquids from China.In Australia, electronic cigarettes are regulated on a state level. Recently, Western Australia banned imports and sales of electronic cigarettes of all kinds.

While imports are still legal for personal use, Australian importers better stay away from electronic cigarettes altogether. Product Certification Requirements Even though regulations specifically for electronic cigarettes are still on the drawing board, in both Europe and America, that is not saying that product certification standards dont apply to the hardware. Electronic cigarettes are subject to certification standards regulating electronic products.

These include the following:European Union RoHS (Assembled product & individual components) CE (Assembled product & individual components) REACH (Mouthpiece & plastic case) Need a helping hand? When you order a Starting Package we source Electronic cigarette suppliers able to show previous compliance, and guide you step-by-step through the whole ordering process. There are several reported casesof e-cigarettes exploding and catching fire.

Keep in mind the importer is always held responsible, in case a product causes personal injury or property damage. Ensuring product certification compliance is always critical when importing from China.
