Business HD SDi Camera – Megapixel Security Cameras
If you haven’t heard, there is now an easier way to have Megapixel High Definition Security Camera Video.
In the past, the only way to accomplish this was with IP Cameras and equipment. That meant that you had to know an awful lot about Networking, Routers, Switches and probably even POE (Power Over Ethernet) equipment.
Now, with the advent of HD-SDI Technology, you can have 2 & 3 Megapixel Cameras and connect them as easily as any analog system. The reason it’s so easy, is that HD-SDI achieves it’s 1080p video over coax. That’s right, over ordinary coax cable.
HD-SDI was developed years ago by the television, studio and video production industries. They invested heavily in this technology and are continually refining, tweaking and expanding the technology and standards. This is what the big boys use when they need to deliver live video from the football stadium out to the production trucks in the parking lot. It is stable, high definition video that works really well over standard coaxial cable.
HD-SDI was then adopted by the security camera industry to provide HD Video that could utilize the coax cable customers already had in place. Thus, the switch from Analog to HD-SDI Megapixel video is quick and simple to accomplish.
What Is Best For Your HD Cameras?
IP Video may be the logical choice for large scale installations that have a lot of cameras, but HD-SDI is proving to be a popular choice for small businesses and retail stores that typically have from one to several dozen cameras. The installation takes less time and labor, there is not as much equipment to buy, and you won’t need to establish a separate Network to handle the bandwidth.
IP cameras use a network, (usually dedicated to cameras), and this requires routers, switches, and possibly POE Devices (Power Over Ethernet). This is a lot of equipment, and requires a lot of specialized knowledge that most people simply don’t possess. If you know a lot about Networking, then IP Cameras may be something that you will be comfortable with. If not, then you need to seriously consider HD-SDI.
The routers, switches and other components are more potential points of failure, and the POE power delivery devices will not be able to power many Infrared or PTZ Cameras because of their high power needs. Also, most POE equipment is designed to deliver 12V DC power, and if you know anything about security cameras, you know that 24V AC is a much better voltage for operating larger cameras and cameras that are more than a hundred feet away. Especially larger cameras. 24V AC is also much better at dealing with nearby high voltage that can interfere with your picture, or have bars or lines running through it.
No Delay – No Compression for Live Video
IP Cameras have a little bit of latency, or delay. The reason for this is that the camera is processing the video, compressing it for transmit, and also providing many of the functions of a normal DVR, such as motion detection, etc. This causes a small delay in the video. Not a whole lot, and certainly not as much delay as there was even a few years ago, but still some delay. This could cause problems, especially if your delay is considerable and you are trying to control a PTZ Camera to follow a person or vehicle. HD-SDI gives you immediate, real-time live video feeds, and does it at a higher quality because the video has not yet been compressed. Thus, if you need the best Live video views, then HD-SDI will be the best option.
Less Cost – Quicker Installation – Better Live Video – Choose HD-SDI
