Video surveillance is within the price range of small businesses now, allowing you to monitor your warehouse, shop floor and parking lot. Cisco network guru Jimmy Ray Purser and I produced a new TechTutor: “How to Do IP Video Surveillance.”
Watch it here.
Key things to keep in mind when considering surveillance cameras, Purser says.
- Make sure the camera’s data streams are encrypted.
- Cameras should be on their own separate network. Otherwise, the “lawyers will chew you up” Purser says (as only JR can) by claiming that the data has been compromised or tampered.
- Make sure that the video surveillance data is protected at rest and that you have a strong ‘chain of custody’ for the data. You need a ’two factor’ situation so that when someone is viewing the data, there’s also someone there monitoring the viewing to be sure the data isn’t tampered.
- You need time-coding on every single frame, with dates and times (down to the milisecond if possible).
- You can run them from your switch is you have a 30-watt switches. These are the switches with a higher power output (normal is 15.4w) to drive larger devices like full motion, free axis cameras.
Cisco recommends that you ask for these features when shopping for an IP video camera surveillance system:
- Pan, tilt, and optical zoom, for more viewing options.
- Power over Ethernet (PoE), which provides power to the camera and connects it to your network all in one Ethernet cable. PoE lets you install a camera where it is needed most, rather than where it is closest to an electrical outlet.
- Wireless access, if you need to install cameras in remote areas.
- Automatic alerts, including video clips or still images, sent whenever motion is detected on the premises.
- The ability to view live video feeds from any Internet-connected PC or mobile phone.
- The ability to integrate alarms, door sensors, motion detectors, and other security systems.
- Support for low- and no-light environments.
- An embedded microphone and speaker for two-way audio.
- Easy-to-operate user interface, for simplified access to captured videos and stills.
- Included surveillance and management software.
