Safe and Sound Becoming More Affordable?
You don’t have to be a large corporation to enjoy the peace of mind that having security cameras can offer. With the cost of these systems coming down, even homeowners and small companies can be alerted if something goes wrong, a crime is being committed or even just to have the comfort of seeing your kids arriving home from school.
Another benefit is that some insurance companies now offer premium savings with installed camera systems. Not only does having such a system provide needed evidence to handle the situation from a criminal prosecution perspective but it also helps keep people honest when they see the property is secured. With the price of cameras becoming more reasonably priced, it may just be in your best interest to look into them.
Read on to learn about IP Cameras….
Why install a dying breed of video cameras by using Analog when IP Cameras have been coming down in cost and have superior clarity?
IP Cameras and how different they are from Analog
IP stands for Internet Protocol, and basically refers to a digital video camera that can send and receive data via a computer network, as opposed to sending a feed to a Digital Video Recorder (DVR). This is advantageous for a lot of reasons:
The best analog surveillance camera still can't hold a candle to the worst IP camera when it comes to the resolution of the image it captures. At best, an analog camera can manage the equivalent of less than half a megapixel. IP cameras capture a much wider field of view than comparable analog cameras, meaning a single IP camera is potentially able to do the job of three to four of the old school cameras.
This is a fancy term that basically means you can set your network to flag “events” that occur in the cameras' field of vision. This could be anything from motion detection to missing objects to tampering with the camera itself. Instead of poring over hours of footage, your network can tell you exactly when these events occurred and point you right to them.
Flexibility and Scalability
In a traditional analog DVR set-up, each camera must be connected directly to the DVR. IP cameras can circumvent this through the use of switches, which then runs a single wire to the Network Video Recorder (NVR). This reduces the amount of cabling runs, which makes it ultimately less labor intensive, and also allows you to connect more cameras because you're no longer limited by the number of ports on your DVR. On top of that, using a Power over Ethernet (PoE) switch allows your Cat 5e or Cat 6 Cable to run the signal and provide power to your camera, eliminating the need for a separate power supply.
More about PoE
PoE is an acronym for “Power over Ethernet” and refers to a system that passes electrical power along with data on an Ethernet cable. This bundles power and data together and removes the necessity of a separate power source, which just adds more cables. A PoE Switch allows you to setup more cameras together to the same Network Video Recorder (NVR). These switches can provide several ports for connecting cameras, and then those PoEs in turn can be connected to a single NVR in a “tree” style configuration, provided your switch is able to handle the power and network traffic. A similar amount of cameras would require additional DVRs in an analog set-up, and that means more cables, and more work.
More about NVR
NVR is an acronym for “Network Video Recorder” and refers to a software program that records video in a digital format to a hard drive, USB flash drive, SD memory card or other mass storage device. An NVR contains no dedicated video capture hardware. However, the software is typically run on a dedicated device, usually with an embedded/installed operating system like Microsoft Windows.
Network Video Recorders are distinct from Digital Video Recorders (DVR) as their input is from a network rather than a direct connection to a video capture card or tuner. Video on a DVR is encoded and processed at the DVR, while video on an NVR is encoded and processed at the camera, then streamed to the NVR for storage or remote viewing.
A commonly asked question “Do I have to post signs if I have video cameras?” The answer is NO. The only time you have to post signs is when audio is being recorded under the Federal Wiretap Act. I always think it’s a good idea to post for video seeing it keeps people honest if they know cameras are present.
