Functions of different CCTV Security Cameras



Confused about which CCTV Camera will best suit your needs?

Just like how important it is to search for a good quality phone or laptop, we should also do the same when we are selecting a CCTV Camera for our home or business. Some would prioritize aesthetics over functionality. Therefore, regardless of whether it is for your business or home, we all have different needs when it comes to purchasing a CCTV Camera.

Here are some of the CCTV Cameras with good functions:


The 2-megapixel network bullet camera


2-Megapixel Network Bullet Camera

More suitable for outdoor installation.

If you are looking for a CCTV that can record in detail, say you want to capture license plates and recognize people’s faces, select at least a 2-megapixel (1920 × 1080) resolution security camera.

With this kind of mega-pixels, you are able to catch a trespasser or gather evidence when a physical breach occurs.

As it comes with a video compressor with high compression ratio, this CCTV Camera is user-friendly as it is able to adapt to different products from different manufacturers such as encoders, decoders and storage media as it is able to inter-operate. This attribute is amplified by a progressive scan CMOS which captures motion video without incised margin.

The Dual-stream in this CCTV Camera allows you to receive and maintain two streams from an analogue or IP camera with different resolutions. An example is when one stream can act as a high definition forensic video for recording, while the other stream can be a lower resolution for live display.

If there was an illegal trespass, this Surveillance Camera supports intrusion detection. Meaning to say, the camera has a line crossing detection which can set the alarm when someone steps after or in that line. With this function your property will be safe and protected, always.  Besides the line crossing detection function, it also comes with an alarm, reset button and a mirror.
