Home video surveillance market is a big cake for video surveillance manufacturers. Since the rapid development of IP-based video streaming technology, there are many traditional CCTV camera manufacturers, as well as explosive growth of start-up corporations are launching megapixel resolution IP cameras to meet this demand. Baycom, headquarter in Hsinchu, Taiwan, the company established in 1990, the company is one of leading IP-based security cameras manufacturer. The company recently released smart Mini Camera series including models K20H, K20, K10.

In order to get an ideal field of view (FOV) for different video surveillance environment, many IP cameras are equipped with vari-focal lens which allow user to adjust the camera focal length. When I browsed Messoa FAQ section in web page, I found a document which teaches users to adjust focus for a clear picture on the megapixel IP camera. Herein we publish its content with purpose to let more people know the correct method to adjust focus on camera.

Almost IP surveillance cameras support RTSP video stream, that means user can use media player to watch the live video from anywhere. RTSP is the abbreviation of real time streaming protocol, it's a network control protocol designed for use in entertainment and communications systems to control streaming media servers. The protocol is used for establishing and controlling media sessions between end points. This article describes how to play RTSP video stream of IP cameras on VLC player, QuickTime player, and a mobile phone with popular IP camera viewer App.

Main-stream and sub-stream concept was first developed by Hikvision. This technology has been used in Hikvision DVR to offer smooth video streaming for remote monitoring. Now it is widely used in DVR, NVR, IP camera across different manufacturers. This technology also called Dual-stream technology, it adopts one channel main-stream to deliver high definition video for local HD video recording/storage, such as 5 megapixel, 3 megapixel, 2 megapixel (1080p), 1.3 megapixel (720p), meanwhile one channel sub-stream to deliver low or standard definition video over Internet for remotely surveillance (e.g. viewing cameras on a smartphone). Dual-stream technology enabled video surveillance products deliver high definition video for local video storage, meanwhile overcomes 3G/ADSL network bandwidth limitation to deliver smooth low/standard definition video.

Unifore, the No.1 DIY HD network camera manufacturer released a new product in its smart HD network camera portfolio. Modern, sleek, D1001 smart HD camera offers modern surveillance beyond security. It's a modern, state-of-the-art security system to protect your home and business. The camera employs latest video technology to deliver HD video with 1280x720 resolution. It is more than a conventional network camera, incorporating with different kinds of security detectors. Users can extend the system not only for video surveillance purpose, but also for burglar deterrent, perimeter protection, burglar and fire alarm.

Different from analog surveillance system, IP camera system requires user to have sufficient network bandwidth for video file transmission. The data rate for a video file is the bitrate. So a data rate specification for video content that runs at 1 megabyte per second would be given as a bitrate of 8 megabits per second (8 mbps). Generally, higher bitrate means higher image quality, but since there is limitation for available network bandwidth and storage capacity for IP surveillance camera, a careful selection of bitrate and file zie is required for a balance between video quality and network bandwidth, as well as storage capacity.

We are seeing the increasing demand of high definition video monitoring for home, shop, office. Thanks for the rapid technology development, video monitoring couldn't be easier before. Today, we are pleased to introduce you the eRobot D1201-A/B, which is a smart IP camera for residential and small business monitoring. The system supports simply installation, and secure WiFi connection, allowing user to record video in 720p HD with audio to the 32GB memory card (not included). This camera not only allows user to view live and recorded video anywhere with included free smartphone App (Android & iPhone), but also giving you a complete security solution through working with 64 wireless sensors.
