Cable Distance Limitations and Solutions
Description
When scoping out a potential location to install a security system, there are often challenges with cable distances. Longer cable runs can be especially challenging if you don't know how to work around these issues. Below are several solutions for HD-CVI and IP bases systems that need cable runs longer than the standard cable distance limitation.
HD-CVI Cable Limitations
- HD-CVI RG59 1650ft
- HD-CVI 75-5 2145ft
1280H(1280×720): 500m via Φ75-3, 650m via Φ75-5
1920H(1920×1080): 300m via Φ75-3, 400m via Φ75-5

Baluns
A balun /ˈbælʌn/ is an electrical device that converts between a balanced signal (two signals working against each other where ground is irrelevant) and an unbalanced signal (a single signal working against ground or pseudo-ground). A balun can take many forms and may include devices that also transform impedances but need not do so. Transformer baluns can also be used to connect lines of differing impedance. Sometimes, in the case of transformer baluns, they use magnetic coupling but need not do so. Common-mode chokes are also used as baluns and work by eliminating, rather than ignoring, common mode signals. -Wikipedia
IP Cable Limitations
- CAT5e/CAT6 = 300ft
