19 IP Video Installation Pointers
Learn a few tips on what to do when installing video surveillance equipment.
The use of network-based technology for signal transport has made all the difference in ease of installation and advances in system functionality. In order to derive the full potential available in most IP-based video surveillance systems it’s imperative that you use the right cable and that it be installed properly.
Here are a few dos and don’ts that security integrators should consider when installing the IP cameras they install:
- You must match UTP connected devices, such as couplers, modular plugs and wall plates, to the Category of the cable used and do so consistently installation-wide
- By design and specification, cable runs in an IP camera system can only extend up to 295 feet for optimum performance
- Bend radius of both Cat-5e and -6 cables must be limited to four times the cable diameter; the accepted bend radius is no less than 1 inch
- Pull tension while installing Cat-5e/-6 cable cannot exceed 25 pounds
- Before stripping the sheath from a cable in a wall box, limit the length so the excess can easily be pushed back into the wall cavity
- Do not staple Cat-5e/-6 cable; instead, use D rings, bridle rings, J hooks and other devices that do not risk altering the outer form or dimensions of the cable
- Maintain a 6-10 inch parallel distance between Cat-5e and -6 cables and those that carry 120/240VAC
- Strip Cat-5e/-6 cables back as little distance as necessary when attaching them to connecting devices
- Use either the T568A or T568B connection format and adhere to just one throughout the entire installation for conformity
Cable is not the only aspect of a successful IP camera installation:
- Whatever the make and model of the IP camera(s) is that you decide to use, it must be suitable for the environment in which it’s deployed
- Consider the amount of low and bright light that your camera(s) will be subjected to when making your camera selection
- Pay particular attention to camera placement, being mindful of the field of view, any obstructions that might prevent a clear of the target
- Be sure there is network connectivity available in the vicinity of where your camera will be placed
- Use surge protection with all outdoor cameras, especially in areas known for lightning
- Assure that the PoE power supply you use is adequate to the job; be sure to compute the power load before making a final choice
- Use a vandal-proof housing in areas prone to crime to assure the integrity of the camera
- Cat-6 UTP is always best, but Cat-5e should do an adequate job of handling most video transport needs which will save money
- Using fiber instead of metallic does have its advantages; foremost it allows you to run camera signals at greater distances and with greater bandwidth than metallic cable can provide
- Last but not least, use safe installation practices to assure that every installer goes home at the end of the day
