The 15 Most Common DVR & NVR Questions
1. How do I locate the model number of my DVR or NVR?
Look for the product label on the bottom or rear of the recorder. The model may also appear on your receipt or order confirmation. Record the model and order number before opening a guide or requesting support.
2. Where can I find my DVR or NVR user manual?
Use the main Technical Support Center and select SureVision, Blue Line or Black Line based on the recorder model.
3. Why didn’t I get an HDMI cable with my DVR or NVR?
Package contents vary by recorder and system. Check the product page or order confirmation. If HDMI is supported but a cable is not included, use a compatible HDMI cable between the recorder and monitor.
4. Does my DVR or NVR have built-in speakers?
Recorders normally do not provide audio through an internal speaker. Use an HDMI monitor or TV with speakers, or compatible powered speakers when the recorder provides an audio output. The camera and recording settings must also support audio.
5. How do I hook up a monitor to my DVR or NVR?
Connect HDMI from the recorder to the monitor and select the correct HDMI input. Many recorders also support VGA. If the display says No Signal, check the cable, input selection and recorder output resolution.
6. Where do I plug in the mouse?
Plug the supplied USB mouse into a USB port on the recorder. The rear USB port is often convenient because it leaves the front USB port available for video export.
7. How do I back up video from my DVR or NVR?
Insert a compatible USB drive, search playback by camera, date and time, select the required clip and export it. Exact menu names vary by recorder line, so follow the backup guide for your equipment.
8. How do I get an older DVR remote control to work?
This applies mainly to legacy equipment. Install fresh batteries and confirm the remote is assigned to the correct recorder device number. Current recorders may not include or support an infrared remote and should normally be operated with the USB mouse.
9. What are the default passwords?
Default credentials vary by equipment generation and should not be assumed. Current equipment normally requires password creation or activation. Use the exact guide for your recorder and change any factory credential immediately.
10. What if my account is locked?
Stop guessing passwords because repeated attempts can extend the lockout. Use the password-reset procedure for your exact equipment line and have the recorder model and local monitor available.
11. How many days of video will my recorder store?
Retention depends on camera count, resolution, bitrate, frame rate, compression, scene activity, drive capacity and recording mode. Use the Hard Drive Calculator for planning.
12. How many hard drives will my DVR or NVR hold?
Drive-bay capacity is model-specific. Check the exact product specifications before purchasing additional storage; channel count alone does not determine the number of drive bays.
13. What hard drives are compatible?
Use a supported surveillance-rated SATA hard drive. Verify the recorder’s maximum drive capacity and bay count before upgrading.
14. How do I set my system to record constantly?
Open the recorder’s recording or storage schedule, select continuous or normal recording for the desired channels and time periods, save the schedule and verify that recording is active.
15. How do I safely turn off my DVR or NVR?
Use the recorder’s on-screen Shutdown function when available. Wait until shutdown is complete before removing power. Never unplug the recorder while firmware is updating or video is being exported.
Choosing Security Cameras, Systems & Recorders
16. What type of security camera systems does CCTV Security Pros sell?
Professional recorder-based surveillance systems, including SureVision PoE IP security camera systems and HD-over-coax CCTV systems.
17. Do your systems require monthly fees?
No required monthly subscription is needed for standard local recording and supported remote viewing. Internet service is still required for off-site access and network features.
18. What is the difference between IP and HD-over-coax systems?
IP systems send video over Ethernet and record to an NVR. HD-over-coax systems send video over coaxial cable and record to a DVR. PoE IP systems can carry power and data through one Ethernet cable.
19. What is the difference between an NVR and DVR?
An NVR records compatible IP cameras. A DVR records compatible analog or HD-over-coax cameras. Confirm camera technology before replacing a recorder.
20. Are wired cameras better than Wi-Fi cameras?
For continuous professional surveillance, wired cameras generally provide more predictable power, network stability and centralized recording. Wi-Fi may help where wiring is impractical.
21. How many cameras do I need?
Plan by coverage goal: entrances, exits, driveways, loading areas, inventory, hallways and vulnerable perimeter points. Leave unused recorder channels for expansion when practical.
22. What NVR channel count should I choose?
Choose enough channels for all planned cameras plus room to grow. Also verify bandwidth, resolution support, PoE capability, storage and analytics.
23. Can I add more cameras later?
Yes, when the recorder has available channels, bandwidth, power and storage. New cameras must also be compatible with the recorder.
24. Can I mix bullet, dome, turret and PTZ cameras?
Yes, when the cameras are compatible with the same system. Different camera types can be selected for different coverage requirements, including fixed cameras and PTZ security cameras.
25. Which is better: bullet, dome or turret?
There is no universal best housing. Choose based on mounting location, visibility, vandal resistance, weather exposure, lens requirements and desired appearance.
26. When should I choose fixed, varifocal or PTZ?
Fixed lenses suit general views, varifocal cameras allow field-of-view adjustment, and PTZ cameras are useful for active control or large areas. Fixed cameras should still cover critical locations continuously.
27. Do I need 4K security cameras?
4K security camera systems can capture more detail but also use more storage and bandwidth. Lens, lighting, distance and placement are just as important as resolution.
28. Do cameras work at night?
Many SureVision cameras include infrared night vision, while select models offer white-light or color night vision features. Performance depends on lighting, distance, lens and mounting.
29. Are SureVision cameras weatherproof?
Many are designed for indoor/outdoor use, but verify the exact model rating. Weatherproof the cable connection separately because the camera housing rating does not protect an exposed Ethernet coupler.
30. Do the cameras record audio?
Select cameras include microphones or two-way audio. Audio must be supported and enabled. Follow applicable recording and consent laws.
31. What is smart motion detection?
Supported SureVision AI security systems can focus detection on people and vehicles to reduce nuisance alerts. Camera position, detection regions and sensitivity still matter.
32. Can I use existing cameras with a new recorder?
Possibly. Verify technology, resolution, codec, ONVIF support, power method and feature compatibility using the exact camera and recorder models.
33. What does ONVIF compatibility mean?
ONVIF can help compatible IP devices exchange video and control functions, but it does not guarantee every advanced feature works between brands.
34. Are SureVision systems NDAA compliant?
CCTV Security Pros identifies NDAA-compliant SureVision products. Compliance should be confirmed for the exact system and procurement requirement.
35. Can a camera work without an NVR?
Some IP cameras can provide limited standalone network functions, but an NVR provides centralized recording, storage, playback and easier multi-camera management.
36. Will the system record if the internet goes down?
Yes. Local recording to the recorder can continue without outside internet as long as cameras, recorder, hard drive and local power remain operational.
37. Do I need a monitor connected all the time?
No. The recorder can operate without a monitor after setup, although a monitor and mouse are valuable for initial configuration and troubleshooting.
38. Can CCTV Security Pros customize a system?
Yes. Our security camera systems can be configured with camera types, recorder size, storage and accessories matched to the property and coverage requirements.
39. Does CCTV Security Pros install systems?
CCTV Security Pros supplies equipment, product guidance and technical support rather than performing the physical installation. A qualified local low-voltage installer can be used when on-site labor is needed.
Installation, Cabling & Initial Setup
40. What should I do before mounting the cameras?
Bench-test the recorder, monitor, mouse, cameras and cables before permanent installation. Verify live video and recording first.
41. What cable do PoE IP cameras use?
Cat5e or better Ethernet cable with properly terminated RJ45 connectors. Use pure-copper cable appropriate for the installation environment.
42. What cable do HD-over-coax cameras use?
Compatible 75-ohm coaxial cable with BNC connectors. Camera power is normally supplied separately or through Siamese cable.
43. How far can I run a PoE camera cable?
Standard Ethernet design is about 328 feet. Select SureVision NVRs support extended PoE distances up to approximately 800 feet under supported conditions and settings.
44. Can I use a PoE switch with the NVR?
Yes, on supported IP systems. Verify port count, PoE wattage and network bandwidth.
45. Which NVR port connects to my router?
Use the recorder’s LAN or network uplink port. Do not use an isolated camera PoE port unless the model instructions specifically call for it.
46. Do the cameras plug directly into the NVR?
Compatible cameras can normally plug directly into built-in SureVision PoE ports. Systems using an external PoE switch use a different network topology.
47. What should I set during the startup wizard?
Create a strong admin password, configure recovery information, set date/time and time zone, verify the hard drive, initialize cameras, set recording and configure the network.
48. What does “initialize camera” mean?
Initialization activates a new IP camera, establishes credentials and prepares it to communicate with the recorder.
49. How high should outdoor cameras be mounted?
Approximately 9–12 feet is a common starting range, but identification cameras may need different placement. Avoid excessively steep viewing angles.
50. Where should cameras be placed?
Prioritize entrances, exits, driveways, approaches, parking, loading areas, high-value spaces and internal travel paths.
51. Do I need a junction box?
A compatible junction box is strongly recommended when connectors cannot remain protected inside a wall or ceiling.
52. How do I protect the system from power problems?
Use grounded power, quality surge protection and preferably an appropriately sized UPS for the recorder, router and network equipment.
53. Can I install the system without internet?
Yes. Local cameras, recording and playback can work without outside internet. Remote access and online services require connectivity.
54. Should I change camera names and passwords?
Yes. Use descriptive camera names and strong unique passwords. Create separate limited-permission users instead of sharing administrator credentials.
Remote Viewing, Apps & Network Access
55. Can I view cameras from a phone, tablet or computer?
Yes. Use the mobile app or desktop software specified for your equipment line and connect the recorder to a working network.
56. How do I set up remote viewing?
Confirm local viewing first, connect the recorder LAN port to the router, verify online/P2P status, install the correct app and add the recorder using its supported QR code or device information.
57. Is the remote-viewing app free?
The standard supported SureVision viewing tools do not require a CCTV Security Pros monthly viewing fee.
58. Can more than one person view the system?
Yes, on supported systems. Use separate user accounts with only the permissions each person needs.
59. Why does the app say the recorder is offline?
Confirm the recorder works locally, then check the router, LAN cable, IP settings, gateway, DNS and P2P/cloud status.
60. Remote viewing stopped after replacing the router.
Reconnect the recorder to the new router and verify that it receives valid network information. Static-IP or older port-forwarding setups may need reconfiguration.
61. Why can I see live video but not playback in the app?
Check the hard drive, recording schedule, recorder time and user playback permission. Test playback locally first.
62. Why am I not receiving motion notifications?
Check detection settings, schedule, push-notification settings, recorder connectivity and phone operating-system notification permissions.
63. Why is remote video slow or blurry?
Remote performance depends heavily on upload speed at the recorder location and connection quality at the viewing device. Use substream viewing when appropriate.
64. Can I share access without sharing the admin password?
Yes. Create a separate user with only the live-view, playback or camera permissions required.
65. Do I need port forwarding?
Many current systems use P2P/device registration and do not require port forwarding. Avoid exposing recorder ports unless your exact setup requires it.
66. How do I protect remote access?
Use strong unique passwords, separate users, secure recovery information, supported firmware and avoid unnecessary internet-exposed ports.
Recording, Playback, Evidence & Video Storage
67. Should I record continuously or only on motion?
Continuous recording gives the most complete timeline. Motion recording can extend retention. Many users record continuously and use motion or smart-event markers for easier searching.
68. Can cameras use different recording schedules?
Yes, on supported recorders. Recording schedules can generally be configured by camera and day.
69. What happens when the hard drive is full?
With overwrite enabled, the recorder deletes the oldest footage and continues recording new video. Export important evidence promptly.
70. How can I increase retention?
Increase supported storage capacity with compatible security camera hard drives for NVRs and DVRs, add drives where supported, optimize bitrate/frame rate and consider motion-based recording where appropriate.
71. How do I search recorded video?
Open Search or Playback, choose the camera and date, then use the timeline or event list to find the incident.
72. How do I save video for police or insurance?
Export the original clip to a clean USB drive, include time before and after the incident, retain an untouched master and test the exported file on another computer.
73. Why won’t an exported video play?
Some recorders export a native evidence format requiring the matching player. Export or download the proper playback utility when needed.
74. Does the recorder store audio?
It can when the camera and recorder support audio and audio recording is enabled. Test recorded playback separately from live audio.
75. Why is there a gap in recorded video?
Check the recording schedule, motion rules, camera connection, recorder power history, hard-drive health and system time.
76. Why do I have live video but no recording?
Confirm a healthy initialized hard drive, correct recording schedule and recording status for the affected channel.
77. Why is playback choppy?
Test one camera at a time, check hard-drive health and compare local playback with remote playback to separate recorder performance from internet bandwidth.
78. Does CCTV Security Pros store my recordings?
Standard recorder-based systems store video locally on the customer’s recorder hard drive rather than requiring CCTV Security Pros to host the recordings.
79. Can I hide private areas?
Supported cameras and recorders may provide privacy masking. Configure the mask after final camera positioning and verify it in live and recorded video.
Camera, Recorder & Image Troubleshooting
80. One camera is offline or has no picture.
Check connectors, PoE/channel status and cable condition. Test the camera using a short known-good cable and known-good recorder port.
81. All cameras are offline.
Check recorder or PoE-switch power, camera port lights, PoE budget, switch uplink and network topology. A simultaneous failure usually points to a shared component.
82. The recorder will not power on.
Verify the outlet, power cord or approved adapter, rear power switch and surge protector. Disconnect unnecessary USB accessories and test again.
83. Why is my NVR or DVR beeping?
Beeping can indicate an exception such as no hard drive, drive error, network loss, video loss or storage issue. Check recorder logs or exception status before silencing it.
84. Recorder is on but monitor says No Signal.
Verify the correct HDMI/VGA input, cable and monitor. The recorder may also be set to an unsupported display resolution.
85. The mouse does not work.
Reseat the mouse, try another recorder USB port and test a basic wired USB mouse.
86. The hard drive is missing or abnormal.
Check storage status and system logs. New drives normally require initialization. Avoid repeatedly formatting a drive if footage is important.
87. Why is the image blurry during the day?
Remove protective film, clean the lens, verify focus when adjustable and confirm the subject is within the intended lens range.
88. Why is the night image white or foggy?
Infrared may be reflecting from a wall, soffit, glass, dome cover, dust or spider web. Clean the camera and aim it away from nearby reflective surfaces.
89. Why is night video black and white?
Standard infrared night mode is normally black and white. Color at night requires adequate ambient/white light or a camera designed for color night viewing.
90. Why do I see insects, webs or floating spots?
Infrared illuminates insects and spider webs close to the lens. Clean the camera and adjust nearby lighting or detection settings.
91. Why does the image flicker or show lines?
Possible causes include cable damage, poor BNC connections, power issues, ground loops, interference or incorrect video format. Test with a short known-good cable.
92. Why is the image pink or purple?
The day/night IR-cut filter may be stuck or the camera may be forced into an incorrect mode. Set Day/Night to Auto and test again.
93. Why does a camera keep restarting?
Check PoE power, cable distance, connectors, water intrusion, switch power budget and IP conflicts. Test the camera on a short cable near the recorder.
94. Why can’t I hear camera audio?
Verify the camera supports audio, the stream and recorder channel have audio enabled and the viewing device is not muted.
95. Why do I get too many motion alerts?
Exclude roads, trees and reflective areas from detection, adjust sensitivity and use human/vehicle detection on supported cameras.
96. PTZ will not pan, tilt or zoom.
Verify power, connection, credentials, user permissions and control settings. Test PTZ locally at the recorder before troubleshooting the app.
97. Why is the recorder date or time wrong?
Set the correct time zone first, then date/time, daylight-saving settings and NTP synchronization when used.
98. System stopped working after a power outage.
Check power to the recorder, PoE switch, router and monitor. Then verify hard-drive health, time settings, camera status and recording.
99. Should I update firmware?
Only use firmware approved for the exact model and hardware revision. Never interrupt an update or install a file intended for a similar-looking model.
100. Should I factory-reset the camera or recorder?
A factory reset should be a later troubleshooting step because it can erase network, recording, user and camera settings. Document the configuration before resetting.
