Understanding Video Loss on Security Cameras

Video loss refers to the sudden interruption or absence of video signals between a security camera and its designated recording device, such as a digital video recorder (DVR) or network video recorder (NVR). When video loss occurs, it results in gaps or missing segments in the recorded footage, leaving blind spots during critical moments.

The impact of video loss goes beyond mere inconvenience. In security scenarios, where cameras serve as the eyes and ears of surveillance systems, the loss of video can be detrimental. Criminal activities, emergencies, or other noteworthy events may go undocumented, hindering the investigative capabilities of the surveillance infrastructure.

What Causes Video Loss in Security Cameras? 8 Quick Solutions

Here are eight common causes and their quick-fix solutions about what causes video loss in security cameras:

1. Insufficient Power Supply

Cause: Insufficient power supply is a frequent cause of video loss in security cameras, leading to issues such as CCTV video loss at night, black screens, or flickering video signals. The common culprits include loose cable connections, unreliable PoE switches or injectors, excessive cable lengths, and faulty power cables.

Solution: Double-check all power connections, use proper PoE equipment, and optimize cable lengths to prevent power loss.

2. Power Spike & Interference

Cause: Power spikes, capable of causing sudden video loss and damage, are a significant threat to video loss on CCTV. Mounting cameras on metal surfaces, lightning strikes, and electrical current interference are common causes.

Solution: Surge protectors and UPS units can mitigate these issues, providing a safeguard against power spikes and ensuring continuous power during outages.

3. Weak WiFi Connection or Low Bandwidth

Cause: When there is no video but camera LEDs are on, most likely there is a weak WiFi connection or low bandwidth. Causes include long distances, WiFi signal interruptions, and insufficient bandwidth.

Solution: Optimize camera placement, check BNC connectors, and evaluate network setups to minimize interference and ensure stable connections.

4. IR Cut Filter and Faulty IR Night Vision

Cause: Issues with infrared (IR) cut filters and faulty IR night vision can cause black screens on CCTV cameras during nighttime surveillance. Common causes include disabled IR and defective IR LEDs.

Solution: Check camera settings to ensure IR is enabled and test IR LEDs in low-light environments.

5. Signal Type and Compatibility

Cause: Mismatched signal types and compatibility issues between cameras and recording devices can lead to video loss and can make cameras black. Causes include resolution mismatches and using cameras from different brands.

Solution: Consult support teams, verify compatibility, and ensure uniformity in equipment.

6. Problems in Cables or Wires

Cause: Cable or wire-related issues, such as twisted or bent cables, can impact surveillance camera functionality. Hardwired cameras are particularly susceptible to video loss due to wiring problems.

Solution: Quick fixes include thorough cable inspections and using new cables to eliminate potential wiring issues.

7. Hardware and Firmware Problem

Cause: Persistent video loss problems may stem from outdated firmware or hardware malfunctions in the NVR/DVR or surveillance cameras.

Solution: Ensure firmware updates and, if necessary, invest in new and quality security cameras and systems.

8. IP Address Conflicts

Cause: Persistent video loss unrelated to power or network issues may indicate IP address conflicts. Duplicated IP addresses can lead to viewing difficulties.

Solution: Check and resolve IP address conflicts, ensuring each device has a unique address.

How to Prevent Video Loss on Security Cameras?

Consider the following tips to prevent video loss:

  • Check All Possible Connections Regularly: Regularly inspect all power and network connections, including power cords, adapters, Ethernet cables, BNC connectors, and cables. Ensure secure and proper attachment to prevent video loss issues and maintain the functionality of your surveillance system.
  • Use Original and Shorter Cable: Opt for shorter BNC or Ethernet cables for your surveillance cameras. Avoid switching original cables to non-professional grade alternatives or using low-quality extension cables, ensuring a stable power supply and reducing the risk of video loss.
  • Use Power Surge Protector and UPS: Install lightning surge protectors to block voltage spikes and surges, safeguarding cameras. Utilize Uninterruptible Power Supply (UPS) units to ensure continuous power during outages, preventing camera power-offs and maintaining surveillance reliability.
  • Choose Reliable Camera System Brands: Prioritize well-received security camera brands, considering customer satisfaction as an indicator of product reliability. Opt for brands with helpful and responsive customer support teams to efficiently troubleshoot any camera system issues. Additionally, purchase security cameras and DVR/NVR from the same manufacturer to avoid compatibility issues.


Video loss on security camera can have significant consequences, jeopardizing the very purpose of surveillance systems. Understanding the causes and implementing effective solutions is essential for maintaining a reliable security infrastructure. Investing in quality cameras, addressing common issues promptly, and adopting preventive measures will ensure that your security system operates seamlessly, providing the protection and peace of mind you expect.


How Long is Security Camera Footage Stored?

The storage duration of security camera footage depends on several factors, including the storage capacity of the system, recording settings, and the number of cameras. In general, footage can be stored for days to several months, with modern systems allowing users to customize storage settings based on their specific needs.

How Often Do Security Cameras Delete Footage?

The deletion of security camera footage is typically governed by the storage capacity and settings configured by the user. Once the storage reaches its limit, older footage may be automatically deleted to make room for new recordings. Users can customize deletion settings based on their preferences and storage requirements.

Are Security Cameras Always Recording?

Security cameras offer various recording modes, including continuous recording, motion-activated recording, and scheduled recording. While some cameras may operate in continuous recording mode, others only record when motion is detected or during scheduled intervals.
