1.Choose the Right Cameras
Choosing the correct camera is of paramount importance. Cameras are available in various shapes (i.e. domes, bullet and box) and have differentiating features such as pan/tilt/zoom (PTZ), varifocal lenses, vandal and weather proof housings. Higher-end cameras have sophisticated smart features such as video analytics and the ability to compensate for low and varying light conditions. Each type of camera can be added into a surveillance system to solve your security needs. Also, consider that not all network cameras are created equal. Some low-cost network cameras may look appealing at first, but security professionals need to understand how the components of a network camera affect the camera’s performance and durability.
2. Calculate the Amount of Bandwidth and Throughput Needed
GovComm provides calculators on our website to resolve bandwidth and throughput requirements. Calculate the amount of bandwidth required on the network by entering the frame rate and resolution. Calculate the throughput on the video server by entering frame rate, resolution and the estimated percentage of recording time.
3. Design the Network
Architecture will make or break the installation. You cannot build a ten story building on the foundation of a one story house. The same holds true with network video surveillance. High-definition video (even when compressed) requires enormous bandwidth and adequate throughput. Failure to properly plan and account for video traffic and power across a network can have catastrophic results.
4. Calculate Storage Requirements
GovComm website calculators are an effective tool to calculate the amount of hard drive space necessary to store a definite number of days of video. Enter frame rates, resolutions, estimated percentages of recording time and the number of days of retention desired to arrive at the storage requirement.
5. Choose Video Servers
The choice of video server depends on factors such as the number of cameras connecting, the amount of throughput on the server versus the cameras throughput requirement, storage, redundancy and of course, price.
6. Address Additional Storage Concerns
GovComm video servers have various combinations of hard drive bays. Whether you are installing a server with one or twenty-four hard drive bays, additional storage may be available locally on the camera with an SD card or on the network with a network attached storage (NAS) device.
7. Address Integration Issues
Many times, third party manufacturers indicate compliance with industry conventions and compatibility. GovComm recommends that you test third party equipment before arriving at the jobsite.
8. Address Video Security
Enterprise video surveillance deployments are generally on their own network with a secure bridge to the entity’s previously existing network for access and viewing purposes. Security for the video server and entire system can be achieved by user name and password authentication, alarming, secure port configuration and more.
9. System Installation
While considering all of the listed factors above, let’s not lose sight that there is no substitute for professional installation practices. Ensure all cables are properly tested, marked and connected in accordance with a wiring diagram. Once the cameras and video servers are installed, make sure the client workstation is robust as well. GovComm recommends a Windows 8 Pro 64-bit operating system with an Intel Core I7 processor, 8GB RAM, 1Gbps network card and a 1 GB onboard video memory graphics card. Make sure to use the latest graphics card driver and the latest service pack from Microsoft. Additional and larger monitors may require additional processing resources.
10. System Testing
After completing installation and configuration of a smart video surveillance system, testing is the cheapest money you can spend. Take the extra time to review every camera performing every function at full throttle to make sure your client receives the system they paid-for and expect.
