Brand Overview

LTS (LT Security Inc.) is an American security company based in City of Industry, California. LTS cameras are manufactured by Hikvision and use Hikvision firmware, protocols, and web interfaces. LTS rebrands Hikvision hardware with US-based technical support and competitive pricing, making it a popular choice in the professional installation market.

Because LTS cameras run Hikvision firmware, they use the same RTSP URL format, ONVIF implementation, and API endpoints as Hikvision cameras. Any integration code written for Hikvision works with LTS and vice versa.

Key facts:

  • Product lines: CMIP (IP cameras), CMHR (HD-TVI analog), LTD (DVRs), LTN (NVRs)
  • Protocol support: RTSP, ONVIF Profile S/G/T, HTTP/ISAPI
  • Default RTSP port: 554
  • Default credentials: admin / 123456 (some models: admin / admin)
  • ONVIF support: Yes (all current models)
  • Video codecs: H.264, H.265 (CMIP4xxx and newer)
  • OEM base: Hikvision (identical RTSP URL format)

LTS = Hikvision OEM

LTS cameras use Hikvision firmware and the exact same RTSP URL format as Hikvision cameras. Any code written for Hikvision cameras works with LTS. See our Hikvision connection guide for additional details.

RTSP URL Patterns

Standard URL Format (Hikvision)

Most current LTS cameras use the standard Hikvision Streaming/Channels URL pattern:

rtsp://[USERNAME]:[PASSWORD]@[IP]:554/Streaming/Channels/[CHANNEL_ID]
Parameter Value Description
CHANNEL_ID 101 Channel 1, main stream
CHANNEL_ID 102 Channel 1, sub stream
CHANNEL_ID 201 Channel 2, main stream (NVR)
CHANNEL_ID 202 Channel 2, sub stream (NVR)

Double-slash in URL

Some LTS/Hikvision cameras use //Streaming/Channels/1 (with a double forward slash before Streaming). Both single-slash and double-slash variants typically work, but try the double-slash version if the single-slash URL fails.

Alternative URL Formats

Some older LTS models or specific firmware versions support these alternative URLs:

URL Pattern Notes
rtsp://IP:554/Streaming/Channels/101 Standard Hikvision (recommended)
rtsp://IP:554//Streaming/Channels/1 Double-slash variant
rtsp://IP:554/live.h264 H.264 live stream (older CMIP3xxx)
rtsp://IP:554/live.sdp SDP live stream (CMIP8xxx)
rtsp://IP:554/HighResolutionVideo Named high-resolution stream
rtsp://IP:554/LowResolutionVideo Named low-resolution stream
rtsp://IP:554/h264/ch1/sub/ H.264 sub stream by channel
rtsp://IP:554/cam1/mpeg4?user=USER&pwd=PASS MPEG-4 with URL-based auth

NVR Channel URLs (LTN Series)

For LTS NVRs (LTN8704, LTN8708, LTN8716, etc.):

Channel Main Stream Sub Stream
Camera 1 rtsp://IP:554/Streaming/Channels/101 rtsp://IP:554/Streaming/Channels/102
Camera 2 rtsp://IP:554/Streaming/Channels/201 rtsp://IP:554/Streaming/Channels/202
Camera N rtsp://IP:554/Streaming/Channels/N01 rtsp://IP:554/Streaming/Channels/N02

Model Series Summary

Model Series Primary RTSP URL Alternative URLs
CMIP3xxx (3MP) /Streaming/Channels/101 /live.h264 (some models)
CMIP4xxx (4MP) /Streaming/Channels/101 /live.h264 (some models)
CMIP8xxx (8MP/4K) /Streaming/Channels/101 /live.sdp, /HighResolutionVideo, /h264/ch1/sub/
LTN NVRs /Streaming/Channels/N01 Channel-based
LTD DVRs /Streaming/Channels/N01 Channel-based

Connecting with VisioForge SDK

Use your LTS camera's RTSP URL with any of the three SDK approaches shown in the Quick Start Guide:

// LTS CMIP3432, main stream (Hikvision format)
var uri = new Uri("rtsp://192.168.1.80:554/Streaming/Channels/101");
var username = "admin";
var password = "123456";

For sub-stream access, use channel ID 102 instead of 101.

Snapshot and MJPEG URLs

Type URL Pattern Notes
JPEG Snapshot http://IP/snapshot.jpg Standard snapshot
3GP Snapshot http://IP/snapshot_3gp.jpg 3GP format (mobile-optimized)
Stream Snapshot http://IP/stream.jpg Stream-based snapshot
DVR Channel Snapshot http://IP/stillimg[CHANNEL].jpg Replace [CHANNEL] with channel number (LTD DVRs)
ISAPI Snapshot http://IP/ISAPI/Streaming/channels/101/picture Hikvision ISAPI (requires auth)

Troubleshooting

Identifying the correct URL format

LTS cameras span multiple generations with different URL formats. To determine which URL your camera uses:

  1. Try the standard Hikvision format first: rtsp://IP:554/Streaming/Channels/101
  2. If that fails, try the double-slash variant: rtsp://IP:554//Streaming/Channels/1
  3. For older CMIP3xxx models, try rtsp://IP:554/live.h264
  4. For CMIP8xxx (4K) models, try rtsp://IP:554/live.sdp

Default credentials and activation

  • Older LTS cameras: default password is 123456 or admin
  • Newer LTS cameras (with Hikvision 5.3+ firmware): require password activation on first use, similar to Hikvision
  • If you cannot log in with default credentials, the camera may need to be activated via the LTS Discovery Tool or Hikvision SADP Tool

Using Hikvision tools with LTS cameras

Since LTS cameras run Hikvision firmware, you can use Hikvision utilities for network discovery and configuration:

  • Hikvision SADP Tool -- discovers LTS cameras on the local network and can activate/reset them
  • LTS Discovery Tool -- LTS-branded version of SADP with identical functionality
  • iVMS-4200 -- Hikvision's free VMS software works with LTS cameras

"401 Unauthorized" error

  1. Verify your credentials are correct (default: admin / 123456)
  2. On newer firmware, ensure the camera has been activated and you are using the password set during activation
  3. Check if the camera has a lockout policy -- too many failed login attempts may temporarily block access
  4. Some models require digest authentication rather than basic authentication for RTSP

Double-slash URL issue

The //Streaming/Channels/1 URL with a double forward slash at the beginning is a known Hikvision pattern. Some HTTP clients or RTSP libraries may normalize this to a single slash. If your connection fails:

  • Ensure your URL string preserves the double slash
  • Try both //Streaming/Channels/1 and /Streaming/Channels/101 variants

FAQ

Are LTS cameras the same as Hikvision?

LTS cameras are manufactured by Hikvision and run Hikvision firmware. The RTSP URL format (/Streaming/Channels/101), ONVIF implementation, and ISAPI interface are identical. The main differences are branding, pricing, and US-based technical support from LTS. Any code written for Hikvision cameras works with LTS cameras.

What is the default RTSP URL for LTS cameras?

For most current LTS cameras, use rtsp://admin:123456@CAMERA_IP:554/Streaming/Channels/101 for the main stream. Use channel ID 102 for the sub stream. Older models may use /live.h264 or /live.sdp instead.

Do LTS cameras support ONVIF?

Yes. All current LTS IP cameras (CMIP series) support ONVIF Profile S and Profile T. ONVIF can be used for automatic discovery and configuration alongside direct RTSP URLs.

What is the difference between CMIP and CMHR series?

CMIP cameras are IP (network) cameras that support RTSP streaming. CMHR cameras are HD-TVI analog cameras that connect directly to DVRs via coaxial cable and do not have network RTSP capability. Only CMIP series cameras can be connected to via RTSP URLs in software.
