NVR Security Systems:
1. NVR surveillance systems do not use more bandwidth than DVR systems.
Note that NVR camera systems do not require the internet to record or save footage.
These systems only consume bandwidth when accessed remotely via phone or PC software.
Some network-friendly brands like Zosi offer choices of fluent and clear video streams to save on bandwidth.
2. When purchasing an NVR and cameras, buy from the same manufacturer to avoid compatibility issues.
Not all IP cameras will work with the network video recorder (NVR) from a specific brand. If you want to add more cameras or find a recorder for your cameras, purchase from the same manufacturer to avoid compatibility issues.
3. If interested in WiFi NVR camera systems, select one with dual-band WiFi signal.
Due to dependency on the internet, wireless NVRs may suffer a signal loss when other wireless electronic devices (i.e., phones) are used simultaneously. It’s best to choose a high-quality WiFi NVR system with a dual-band boosted WiFi signal.
DVR Security Systems:
Admittedly, the digital video recorder (DVR) has a price advantage, though it is less competitive today due to some obvious inconveniences.
1. Running cable is challenging for DVR systems.
The hard wiring necessary for DVR cameras is their biggest disadvantage. Each camera requires two cables — one for power and one for audio and video — and this could become even more difficult if monitoring places are out of reach of the coax cable.
2. DVR CCTV systems deliver lower-quality videos.
Although new technology has improved the recording quality of analog cameras, it still can’t match NVR cameras. Some MPX cameras have higher resolution capabilities, but they can be more expensive than NVR cameras.
3. Equipment needs to be closer in DVR security systems.
DVR IP cameras must be placed no more than 300 feet away from the DVR to prevent a decaying signal over the coax cable.
4. DVR camera systems have a higher maintenance cost.
The DVR system transmits the signal via coax cables, which are more vulnerable to the elements like rain and wind, leading to expensive fixes.
5. Digital video recorders have lots of potential issues to deal with.
Although the DVR system isn’t outdated, it’s becoming less popular every year, leading to potential problems homeowners might not have considered. For example, new homeowners might find no coax cable prewired to support the DVR system.
The verdict: NVR vs. DVR system, What you need to consider
The choice between NVR and DVR systems should be largely based on the wiring task.
